[00:58] <DoYouKnow> hi juxta
[00:58] <juxta_> hey DoYouKnow
[00:58] <DoYouKnow> _
[00:58] <juxta_> MikeMc68, I forgot to ask you, does your GPS output RMC?
[01:06] <natrium42> juxta_, i think he went to bed
[01:06] <natrium42> [19:13] <MikeMc68> i have to be up in 5 hours to drive to Cambridge
[01:06] <natrium42> [19:13] <MikeMc68> talk tomorrow - night
[01:06] <Randomskk> juxta_: if it's a gps usb mouse thing it really should
[01:06] <Randomskk> all the ones I've seen do
[01:06] <juxta_> ah right
[01:06] <juxta_> cool cool
[01:07] Action: Randomskk sleep now, seeya all tomorrow
[01:07] <Randomskk> fun exciting launch tiems
[01:07] <natrium42> nite Randomskk
[01:07] <natrium42> landing prediction almost done ;)
[01:07] <Randomskk> oh natrium42: could you clear the current track on the tracker?
[01:07] <natrium42> yeah
[01:07] <Randomskk> cheers
[01:07] <natrium42> i will be playing with it shortly
[01:07] <Randomskk> checksum's working nicely on crc16 now
[01:07] <natrium42> excellent, great work
[01:08] <Randomskk> and also if it loses lock it will transmit last known position and negate the number of satellites in view
[01:08] <DoYouKnow> so are you guys launching this weekend?
[01:08] <juxta_> natrium42, hang around for a few minutes if you can, I was going to ask you a couple of bits :)
[01:08] <Randomskk> so if satellites in view is <=0 it doesn't have lock, but still says where it was last time it did
[01:08] <Randomskk> DoYouKnow: tomorrow 10am UTC
[01:08] <DoYouKnow> the cambridge group
[01:08] <DoYouKnow> cool
[01:08] <DoYouKnow> hopefully it will make it to above 30000m
[01:08] <Randomskk> it's actually a guy from uni kent, but we are launching it and also sticking a quick and dirty radio tracker on
[01:08] <DoYouKnow> :)
[01:08] <natrium42> juxta_, not going to sleep for a couple of hours yet
[01:08] <Randomskk> yup though we probably won't get confirmation of that
[01:09] <Randomskk> gps we are using is meant to cut out at 24km
[01:09] <Randomskk> probably go on a bit longer but probably not to 30km
[01:09] <DoYouKnow> ok
[01:10] <Randomskk> anyway we'll see tomorrow
[01:10] <Randomskk> seeya all
[01:10] <DoYouKnow> l8r random
[01:14] <juxta_> hey natrium42
[01:15] <juxta_> sorry about that - I was just going to ask you about the data fields on the payload I'm launching on monday
[01:15] <juxta_> I've just got 3 things in custom data: number of GPS sats, internal temp, external temp - can we rig it up so that they show up on the tracker?
[01:15] <juxta_> I tried it last night and they just showed as a single 'data' field

[03:12] jedahan (~jedahan@ool-45714877.dyn.optonline.net) joined #highaltitude.
[03:14] <jedahan> Is there a formula for bursting height based on free lift / size of balloon? We are using a Kaymont KCL 800 and winds picked up so we want to lower the bursting height / shorten the entire trip

[03:21] <natrium42> juxta, ok, i'll add it after todays launch
[03:21] <juxta_> cheers natrium42
[03:21] <natrium42> jedahan, check burst1a.xls on the ukhas wiki
[03:21] <juxta_> I just cleared off my test tracks from the tracker, accidentally cleared orion too, hopefully wasnt important =\
[03:22] <natrium42> yeah, that's fine
[03:22] <juxta_> nice work with the car icons btw :)
[03:22] <juxta_> anything with a chase- prefix gets a car?
[03:23] <natrium42> yeah, "chase" or "car" inside name
[03:23] <natrium42> had to add exception for "icarus" XD
[03:23] <juxta_> haha
[03:26] <jedahan> natrium42, thanks!
[03:27] <natrium42> np
[03:27] <juxta_> i'm driving my chase car at 1800km/h in Guinea at the moment :D
[03:28] <natrium42> rofl
[03:28] <natrium42> uh oh, if you add two more cars it runs out of colours
[03:29] <juxta_> hmm
[03:29] <natrium42> err
[03:29] <juxta_> didnt the payload colour match up with the track colour in the past?
[03:29] <natrium42> well, i have 4 colours atm
[03:29] <juxta_> also, you spell colour right, woo
[03:30] <natrium42> haha, canadian english :)
[03:30] <natrium42> var car_colors = ["red", "blue", "green", "yellow"];
[03:30] <natrium42> var balloon_colors = ["blue", "red", "green", "yellow"];
[03:30] <natrium42> var color_table = new Array("#0000ff", "#aa0000", "#006633", "#ff6600", "#003366", "#CC3333","#663366" ,"#000000");
[03:31] <natrium42> track colours are unique, so it can be off
[03:31] <natrium42> it works out correctly if you have (balloon, car, ...)
[03:32] <juxta_> ahh right
[03:32] <juxta_> we should have 2 chase cars on monday
[03:32] <juxta_> maybe 3 though
[03:32] <juxta_> we'll see I guess :)
[03:32] <natrium42> wow, nice :)
[03:32] <juxta_> if it runs out of colours, what happens?
[03:32] <juxta_> no track drawn?
[03:33] <natrium42> i can make it roll over if you have more than 4 cars or more than 4 balloons
[03:33] <juxta_> i can start up a few chase cars to see how it behaves if you like
[03:33] <natrium42> it doesn't bound check the array atm
[03:33] <juxta_> oh right
[03:33] <natrium42> so javascript will bug out
[03:33] <juxta_> bummer
[03:33] <natrium42> but i can make it roll over
[03:34] <juxta_> alrighty
[03:34] <natrium42> you can still tell the vehicle by the info boxes
[03:34] Action: natrium42 should add tool tips
[03:34] <juxta_> oh yeah
[03:34] <natrium42> just finishing landing prediction atm
[03:34] <juxta_> is the path off for cars by default?
[03:34] <natrium42> yep
[03:34] <juxta_> landing predictions?
[03:34] <juxta_> as in live landing predictions?
[03:34] <natrium42> yeah, integrating the CUSF code
[03:35] <juxta_> :O
[03:35] <juxta_> awesome!@
[03:35] <natrium42> should be live for todays launch
[03:35] <juxta_> oh brilliant
[03:35] <juxta_> does it switch on in descent mode?
[03:35] <juxta_> or at all times?
[03:35] <natrium42> did the cusf predictor work for you in australia?
[03:35] <natrium42> at all times
[03:35] <juxta_> yeah it works down here
[03:36] <natrium42> k, excellent
[03:36] <juxta_> :)
[03:36] <juxta_> how do you specify burst alt when the balloon is in asc?
[03:36] <natrium42> right now there's a config.php with all the launch settings
[03:36] <juxta_> oh ok
[03:36] <natrium42> but planning to add a proper backend soon
[03:37] <natrium42> so that you can login and change things
[03:37] <juxta_> if it's in descent mode it should be able to skip the burst alt, yeah?
[03:37] <natrium42> yep
[03:37] <juxta_> ie if it bursts early etc
[03:37] <juxta_> thats very cool :)
[03:38] <juxta_> one of the reasons for this launch I'm doing is to get a good data set with a properly deployed chute, I want to have a crack at on-balloon prediction
[03:38] <natrium42> yeah, the cusf guys did a great job
[03:38] <juxta_> based on the ascent winds
[03:38] <natrium42> :)
[03:39] <juxta_> & hopefully with crc16 we should get less buggy positions
[03:39] <natrium42> there's some code on the wiki which does landing prediction based on wind history from the ascent
[03:39] <juxta_> yeah, thats the type of thing I want to do
[03:39] <juxta_> need a rough value for drag coefficient though
[03:39] <natrium42> i.e. it doesn't need weather data
[03:39] <natrium42> could calculate it
[03:39] <juxta_> which I dont have given my balloon tumbled to the ground last time
[03:39] <juxta_> true ;p
[03:40] <natrium42> you mean drag coefficient of parachute?
[03:40] <juxta_> of the whole lot together
[03:40] <natrium42> right
[03:40] <juxta_> parachute, payload, burst balloon, lines, radar reflector etc
[03:40] <natrium42> i think i will use your first flight data for testing as i have it saved :P
[03:41] <juxta_> hehe
[03:41] <juxta_> actually, let me know how it works
[03:41] <juxta_> i'd be very interested to see
[03:41] <natrium42> sure
[03:41] <juxta_> does the code rely on a defined descent rate at sea level? or can it work by calculating the sea level descent based on current descent & air density?
[03:42] <juxta_> (assuming the balloon has already burst)
[03:43] <natrium42> here is the current altitude model --> http://github.com/rjw57/cusf-landing-prediction/blob/master/pred_src/altitude.c
[03:44] <juxta_> oh, I was going to ask too - if I set my callsign in fldigi to the same thing as my chase car name, will the tracker draw the listening line to the chase car?
[03:45] <natrium42> yes
[03:45] <natrium42> but to the current position
[03:45] <natrium42> i was thinking of keeping positions of where a radio string was received
[03:45] <juxta_> ah
[03:46] <juxta_> doesnt really matter, but thats very cool
[03:46] <juxta_> I will set fldigi accordingly :D
[03:46] <natrium42> :)
[03:47] <natrium42> hrm, actually is fldigi updating your receiver position?
[03:47] <juxta_> my chase car?
[03:47] <juxta_> no, that's an app I wrote
[03:48] <natrium42> hrm
[03:48] <natrium42> well, it's like a one line change
[03:48] <natrium42> i'll add it
[03:51] <juxta_> this is going to be great to see it all in action
[03:57] <juxta_> what the.. does java not have a round method to round to a number of decimal places? =\

[05:17] <DoYouKnow> is it true that the passive force of wind resistance subtracts from the force of buoyancy to give a constant velocity of ascent?

[05:41] <MikeMc68> too early
[05:41] <natrium42> hi mike
[05:42] <natrium42> i got rudimentary landing prediction integrated
[05:42] <natrium42> going to test a bit
[05:42] <MikeMc68> cool
[05:43] <natrium42> getting the weather data for today
[05:49] <juxta> morning mike_jh_
[05:49] <juxta> MikeMc68*
[05:49] <juxta> looks like a good day for launch natrium42 ;)
[05:50] <natrium42> haha, check the date :P
[05:52] <natrium42> refresh for correct one
[05:54] <juxta> ah right :)

[05:59] <MikeMc68> landing predicition is better this morning too
[06:02] <juxta> hey mike_jh_
[06:02] <juxta> MikeMc68*
[06:02] <juxta> did you get my email?
[06:08] <natrium42> k, prediction seems to be working
[06:10] <juxta> great :)
[06:10] <natrium42> hmm, do you think prediction track is too similar to real track?
[06:11] <natrium42> should i make it more transparent or thinner?
[06:11] <juxta> I was just about to say something along those lines
[06:11] <juxta> does google maps let you do a dotted line?
[06:11] <natrium42> don't think so :S
[06:11] <juxta> bummer
[06:11] <juxta> hmm
[06:11] <natrium42> you can always write your own line renderer...
[06:11] <natrium42> but i would rather not
[06:11] <juxta> fair enough
[06:12] <juxta> maybe a bit more transparent then
[06:12] <natrium42> what about http://spacenear.us/tracker/index2.php
[06:12] <natrium42> ?
[06:12] <natrium42> that's 1 pixel thickness instead of 2
[06:12] <juxta> oh yep, that works too
[06:12] <juxta> is the normal track 3 thick?
[06:13] <natrium42> 2 pixels
[06:13] <natrium42> refresh now
[06:13] <natrium42> that's 2 pixe, but higher transparency
[06:13] <juxta> ah
[06:13] <juxta> hmm, it looks thinner than the path
[06:13] <natrium42> which one?
[06:13] <natrium42> err, which one is better?
[06:14] <juxta> I prefer the thicker prediction line
[06:14] <juxta> (more transparent)
[06:14] <natrium42> kk
[06:14] <natrium42> rofl, 10 pixels thickness
[06:14] <juxta> heh
[06:15] <juxta> little too thick maybe
[06:15] <natrium42> indeed
[06:15] <natrium42> ok, i'll leave it at 2
[06:15] <MikeMc68> juxta yes thanks
[06:15] <natrium42> going to add burst point, etc later
[06:15] <juxta> maybe its the angle that makes it look thinner than the actual flight path
[06:15] <juxta> good-o MikeMc68
[06:35] <MikeMc68> ok guys off to Cambridge
[06:36] <MikeMc68> talk again in a few hours

[07:40] <Randomskk_> still need to get dressed etc, couple of mins
[07:40] <Randomskk_> so uh
[07:40] <Randomskk_> there might have been quite a low impedance path to ground from the RF output
[07:41] <jonsowman> what shorted where?
[07:41] <Randomskk_> coax braid to the stripboard for the center conductor? and it'd been like that from the start?

[07:44] <Randomskk_> wondered what was going on the first time
[07:44] <Randomskk_> especially since the charger said the battery was charged
[07:44] <Randomskk_> but it didn't the second time
[07:44] <juxta> it sounds a bit alarming, doesnt it
[07:45] <jonsowman> very
[07:45] <jonsowman> hmm.. didnt know this time existed on a sunday morning
[07:45] <jonsowman> havent been up before 11 in ages
[07:45] <Randomskk_> I know right
[07:45] <Randomskk_> juxta: it does rather
[07:46] <jonsowman> ok so landing prediction puts us back near oxford again
[07:46] <jonsowman> shifted west again quite a bit
[07:46] <Randomskk_> is that good
[07:47] <jonsowman> yes
[07:47] <jonsowman> further away from london
[07:47] <Randomskk_> nice
[07:47] <jonsowman> i'm ready Randomskk_ tell me when i can come down

[07:50] <jonsowman> morning edmoore
[07:50] <Randomskk_> jonsowman: may as well come down now
[07:50] <edmoore> hi jonsowman
[07:50] <Randomskk_> I'm decent :P
[07:50] <Randomskk_> yo ed
[07:50] <jonsowman> predictions look a little better today
[07:50] <jonsowman> Randomskk_: omw
[07:51] <edmoore> so they do so they do
[07:51] <edmoore> have you guys used the burst1a.xls spreadsheet?
[07:52] <jonsowman> yeh a long time ago
[07:52] <edmoore> you'll want to know how much neutral ballast to use today
[07:52] <jonsowman> also edmoore did you contact MikeMc68? i assume you saw the email
[07:52] <jonsowman> is there wifi at chu?
[07:52] <edmoore> no i was without phone sorry
[07:52] <edmoore> which email?
[07:52] <edmoore> i don't seem to have it here
[07:53] <jonsowman> he wanted to know if he could park at chu
[07:53] <edmoore> there's loads of space
[07:53] <jonsowman> ok
[07:54] <jonsowman> i've already texted him this morning saying come to chu, we'll sort out parking once you're there
[07:54] <jonsowman> right see you in a bit edmoore
[07:54] <edmoore> see you
[07:58] <Randomskk_> <jonsowman> is there wifi at churchill edmoore?

[08:38] <edmoore> a picturesque launch then
[08:39] <Randomskk_> sunny here too
[08:39] <Randomskk_> funny that
[08:39] <LazyLeopard> clear sky, touch of frost, no wind.

[08:42] <rharrison_> Where and who is launching?
[08:43] <jcoxon> guy from kent uni + hacked together radio tracker by Randomskk_ and jonsowman
[08:43] <rharrison_> cool :)
[08:43] <rharrison_> Should be a lovely day
[08:43] <rharrison_> I wanted to launch this w/e
[08:43] <rharrison_> Buy wifes off and away on girly w/e
[08:44] <jcoxon> rharrison_, there are always other weekend :-)
[08:44] <rharrison_> but
[08:44] <jcoxon> the forecast has been a bit dodgey as well
[08:45] <rharrison_> Yep and this one has a lunch in it so we shouldn't be gready
[08:45] <rharrison_> True
[08:45] <rharrison_> jcoxon you in london?
[08:45] <jcoxon> yup
[08:46] <rharrison_> Cool
[08:46] <rharrison_> So tracking on the coxon moxon
[08:46] <rharrison_> I have just cleared down the tracker
[08:46] <rharrison_> are they using fletecher
[08:46] <rharrison_> FLetcher
[08:47] <rharrison_> If so I will need on quick flick on the listener
[08:47] <jonsowman> hi rharrison_
[08:47] <Randomskk_> no
[08:47] <Randomskk_> crc16
[08:47] <rharrison_> oooh
[08:47] <rharrison_> Sexy
[08:47] <rharrison_> Cool
[08:47] <jonsowman> any chance you could quickly clear view.php for us?#
[08:47] <Randomskk_> and was working fine last night
[08:47] <Randomskk_> i.e. it was validating the checksum
[08:47] <rharrison_> First use of the crc16 for a live tracking
[08:48] <rharrison_> Excelent
[08:48] <rharrison_> Launch ETA
[08:48] <rharrison_> ETL even
[08:48] <jonsowman> 1000
[08:48] <rharrison_> Awfumness
[08:48] <edmoore> 1000 hrs but scotty just texted to say he can't get here till 9.15
[08:48] <rharrison_> Awesumness
[08:48] <edmoore> so 1000 strongly depends on speed of integration
[08:48] <rharrison_> Hehe so at 12 then
[08:49] <rharrison_> What is scotty providing
[08:49] <rharrison_> Box and camera?
[08:49] <jonsowman> yup
[08:49] <jonsowman> two cameras - still and video
[08:49] <rharrison_> Does this launch have a name?
[08:49] <Randomskk_> orion
[08:50] <jonsowman> link to payload pics on the ukhas current launch page
[08:50] <rharrison_> I'll update mobile php
[08:50] <Randomskk_> cheers
[08:50] <Randomskk_> which are the useful links?
[08:50] <Randomskk_> rharrison_: could you clear view.php too please?
[08:50] <rharrison_> Sure
[08:50] <rharrison_> holy crap it's a biggy
[08:51] <rharrison_> The payload
[08:54] <rharrison_> NB view.php can me used with reg expressions http://www.robertharrison.org/listen/view.php?reg=/ORION/
[08:54] <rharrison_> or your call sign if you just want to see your own lines
[08:55] <jonsowman> ah nice one
[08:55] <jonsowman> thanks rharrison_
[08:55] <jonsowman> :)
[08:57] <fsphil> morning all
[08:57] <Randomskk_> yo
[09:00] <jcoxon> nice tidy electronics in scotty's paylaod
[09:00] <LazyLeopard> dl-fldigi sets 7,N,2 for "orion" but webpage says 7,N,1.5. Presumably web page is correct.
[09:01] <rharrison_> http://www.robertharrison.org/mobile.php
[09:01] <jonsowman> pretty sure it's 1.5 stop bits in fldigi
[09:01] <jonsowman> but will check now
[09:01] <jonsowman> 2 secs
[09:01] <Randomskk_> jcoxon: ours will more than make up for that, no worries
[09:01] <jcoxon> LazyLeopard, xml says 1.5
[09:02] <Randomskk_> it's an arduino sized bit of stripboard with a dremel-cut down the middle to split the tracks
[09:02] <LazyLeopard> Ah. Got set to 2 when I selected "orion". I'll check again...
[09:02] <rharrison_> Possibly one for bug list then LazyLeopard
[09:02] <Randomskk_> with a few passives and the ntx2 and gps
[09:02] Nick change: Randomskk_ -> Randomskk
[09:03] <rharrison_> Randomskk cool
[09:03] <jonsowman> LazyLeopard: 1.5 stop bits it is
[09:03] Nick change: rharrison_ -> rjharrison
[09:03] <Randomskk> also it's in a maplin project box covered in blue tape :p
[09:03] <Randomskk> with the fantastic straw antenna
[09:03] <Randomskk> have to upload some photos
[09:03] <jcoxon> Randomskk, link them to the wiki as well
[09:03] <jcoxon> we should make more of the current launch page really
[09:03] <rjharrison> jcoxon i'm not going to be at my desk for launch assume you can manage the tracker
[09:04] <jcoxon> yup
[09:04] <jcoxon> no problem
[09:04] <Randomskk> have to wait til I get back to upload photos unfortunately
[09:04] <Randomskk> might be able to do one or two from my phone actually
[09:05] <rjharrison> Fingers x'ed shold be real smooth running of fl-digi today
[09:05] <rjharrison> I'm looking for perfect data capture subject to tx being correct :)
[09:05] <LazyLeopard> Hmmm... Strange. Came up 2 for me first time round. Now comes up 1.5. Must've failed to hit "Save" or something...
[09:05] <rjharrison> LazyLeopard :) cool
[09:05] <LazyLeopard> 1.5 is good.
[09:05] <jcoxon> though have to disappear at 12.30 so will hopfully its up by then
[09:05] <edmoore> jcoxon: i hope so!
[09:05] <rjharrison> I'll ne online by then
[09:05] <fsphil> my rtty settings don't change when I selected orion?
[09:06] <jcoxon> rjharrison, okay cool - team work :-)
[09:06] <jonsowman> fsphil: do they match the ones on the current launch page?
[09:06] <jcoxon> fsphil, you have an old version of fldigi
[09:06] <rjharrison> Is there a prediction anywhere
[09:06] <jcoxon> r63
[09:06] <rjharrison> save some cpu cycles on the CUSF
[09:07] <jcoxon> will need to update to the r8x to get complete changes
[09:07] <jonsowman> rjharrison: will sort one quickly now
[09:07] <fsphil> ah, one sec thanks jcoxon
[09:07] <jcoxon> rjharrison, was a good thing we started reporting which version people were using to help debugging
[09:08] <rjharrison> yep
[09:08] <rjharrison> jonsowman do I need to do a build?
[09:08] <jonsowman> http://www.srcf.ucam.org/~js843/orion1.png
[09:09] <jcoxon> Randomskk! you have a very old version of dl-fldigi
[09:09] <Randomskk> ah
[09:09] <Randomskk> laptop
[09:09] <jcoxon> from before it even reported the version!
[09:09] <Randomskk> ...ah
[09:10] <Randomskk> http://twitpic.com/174t1g
[09:10] <jonsowman> prediction link added to current launch page
[09:10] <Randomskk> oh right, this is because linux requirs compiling it
[09:10] <Randomskk> probably not got time atm
[09:10] <LazyLeopard> dl-fldigi r86 has that checksum fix, but latest downloads are r83 for OS-X leopards, and r85 for vista.
[09:10] <Randomskk> my desktop has the latest version
[09:10] <Randomskk> it still works :p
[09:11] <jcoxon> love the ferret tracker
[09:11] <fsphil> r87 stable enough, before I compile it here?
[09:11] <Randomskk> trying it now
[09:11] <Randomskk> jcoxon: got some inside pics too actually
[09:11] <jcoxon> r86 is best
[09:11] <jcoxon> though thinking about it - just get the latest trunk
[09:11] <fsphil> oh that is a cool antenna
[09:11] <fsphil> the iAntenna
[09:12] <jcoxon> i've branched it to do my experimental work
[09:12] <jcoxon> fsphil, where are you based?
[09:13] <fsphil> Cookstown, roughly in the middle of n.ireland
[09:13] <jcoxon> :-)
[09:13] <jcoxon> long range then
[09:13] <fsphil> very - should be above my horizon, just curious if I can hear anything
[09:14] <jcoxon> yeah, got a yagi?
[09:14] <Randomskk> antenna closeup
[09:14] <Randomskk> http://twitpic.com/174top
[09:14] <fsphil> yep, 10 element
[09:14] <jcoxon> fsphil, okay cool
[09:15] <jcoxon> fsphil, if you fill in rough lat and lon into dl-fldigi then it'll plot you on the map
[09:15] <fsphil> being the svn newbie that I am, this right for grabbing the latest trunk?: svn checkout http://dl-fldigi.googlecode.com/svn/trunk/ dl-fldigi
[09:15] <jcoxon> then we can work out distances
[09:15] <jcoxon> fsphil, yeah that'll do it
[09:16] <Randomskk> ferret internal http://twitpic.com/174u2s
[09:16] <jcoxon> Randomskk, did the annoying arduino spacing cause trouble?
[09:17] <Randomskk> no
[09:17] <jcoxon> Randomskk, also that cable tie over the gps could cause a little issue
[09:17] <Randomskk> we didn't need anything on the top pins
[09:17] <Randomskk> jcoxon: hmm
[09:17] <Randomskk> I mean, it works fine in testing
[09:17] <jcoxon> oh okay then
[09:17] <jcoxon> they have a habit of desensitising
[09:17] <edmoore> no scotty yet
[09:18] <jcoxon> but if it works then don't worry
[09:18] <jcoxon> Randomskk, looks good :-D
[09:18] <Randomskk> stil installing deps for fldigi lol
[09:20] <fsphil> man gcc's getting picky in its old age
[09:20] <Randomskk> okay
[09:20] <Randomskk> I don't need xml-rpc for dl-fldigi right?
[09:21] <jcoxon> Randomskk, nah
[09:21] <jcoxon> hmmm i think its time to kick simrun to make some more debs for linux
[09:21] <Randomskk> got hamlib and pulseaudio
[09:21] <Randomskk> I could probaby make some, jcoxon
[09:21] <fsphil> I can cook together an rpm for fedora too
[09:21] <Randomskk> my desktop has everything needed
[09:21] <jcoxon> i can give you guys uploading rights to googlecode
[09:22] <Randomskk> hmm and I do have a 32 and 64bit machine
[09:22] <Randomskk> should be easy enough to make some ubuntu ones
[09:22] <Randomskk> could make a ppa (small apt repository that ubuntu hosts)
[09:23] <Randomskk> then people can just apt-get install and later upgrade
[09:23] <Randomskk> ugh forgot about this
[09:23] <Randomskk> it has a compile error
[09:24] <fsphil> you need to cast the Q* strings to (char *)
[09:24] <fsphil> was the error I had just now anyway
[09:25] <Randomskk> cheers, there we go
[09:25] <Randomskk> quick search and replace
[09:25] <Randomskk> yea, had the same issue on my desktop
[09:25] <edmoore> scotty is here
[09:27] <fsphil> hehe, remembered the minus in the longitude this time. Don't want to be in the north sea again
[09:27] <Randomskk> fsphil: there's another make error in picture.cxx
[09:27] <fsphil> yep, text needs to be cast aswell
[09:28] <Randomskk> oh yup
[09:28] <Randomskk> cool
[09:28] <fsphil> seems strange for gcc to error on that
[09:28] <jcoxon> fsphil, Randomskk do you need this fixed in the main source?
[09:28] <fsphil> would be handy, jcoxon
[09:28] <fsphil> can I use svn to make a patch?
[09:29] <jcoxon> fsphil, you could use svn to diff the changes you've made
[09:29] <jcoxon> and then email me them and i'll correct it
[09:29] <Randomskk> jcoxon: it's an error upstream
[09:29] <Randomskk> in fldigi proper, I think
[09:29] <Randomskk> qrzlib and a picture widget
[09:29] <Randomskk> but yea, we can maintain a patch
[09:30] <Randomskk> anyway compiled and working
[09:30] <Randomskk> now got the latest trunk
[09:30] <fsphil> yep, up and running here too
[09:31] <fsphil> and it's picked all the proper rtty settings
[09:32] <jcoxon> i think we should make a listener scoring system
[09:32] <fsphil> is the fldigi source relatively hacker friendly, jcoxon? I've a few ideas I'd like to try for my own launch
[09:33] <jcoxon> something like number of strings multiplied by distance from payload
[09:33] <Randomskk> jcoxon: need to sort out tracker identity first though
[09:33] <jcoxon> fsphil, it is - if they are ideas that could benefit everyone then it would be great if they could be rolled into the main setup
[09:33] <edmoore> i'm up for the scoring sstem
[09:34] <Randomskk> currently so many dupes etc
[09:34] <edmoore> yagi stack on trackatron here we come
[09:34] <jcoxon> edmoore, yeah but you are close so you get less multipliers
[09:34] <fsphil> jcoxon: I had this crazy idea of sending small jpeg files over rtty. would be simpler for me than sstv
[09:34] <fsphil> with some error correction, it might work
[09:34] <jcoxon> fsphil, that is crazy :-p might find that there are better setups then fldigi
[09:35] <jcoxon> which will give you better access to the data stream
[09:35] <Randomskk> fsphil: there is a program made by the fldigi guys
[09:35] <Randomskk> for just that
[09:35] <Randomskk> sending files over fldigi that is
[09:35] SpikeUK (~chatzilla@host86-163-204-220.range86-163.btcentralplus.com) joined #highaltitude.
[09:35] <jcoxon> that said if you can tap into the stream then lots of people would be happy as they could get there super FEC working
[09:36] <Randomskk> flarq
[09:36] <fsphil> ah, i saw that mentioned on the website Randomskk - wasn't sure what it was
[09:37] <jcoxon> hmmm they just released a big update to fldigi

[10:02] <jcoxon> ooo new fldigi has custom shift
[10:02] <jcoxon> and reedsolmon on rx and tx
[10:03] <jcoxon> oooo and a waterfall only mode
[10:04] <fsphil> at last!
[10:04] <fsphil> none of the resistors I have give a standard shift :)
[10:04] <SpeedEvil> fsphil: parallel some then
[10:05] <fsphil> will try that tonight
[10:06] <SpeedEvil> But custom shift is great.
[10:06] <SpeedEvil> However - sticking to the standards has plusses
[10:06] <fsphil> true - though didn't BH4's shift change during flight?
[10:07] <SpeedEvil> yes, that's another issue
[10:07] mickw (~5606ef4c@gateway/web/freenode/x-xjtebspoqwhpvfkj) joined #highaltitude.
[10:07] <jcoxon> something to work on...
[10:07] Action: LazyLeopard wonders what the HAB button in dl-fldigi does (apart from turn red if you click it once, and then stay red...)...
[10:08] <fsphil> a big red button?
[10:08] <fsphil> cool
[10:08] <SpeedEvil> The 'right' solution would be to get fldigi to be able to autotrack variations in shifts. But that's a fair bit harder
[10:09] Laurenceb (~laurence@host81-157-248-47.range81-157.btcentralplus.com) joined #highaltitude.
[10:09] <djellison> The shifts drift - I've always wanted custom shift :)
[10:09] <jcoxon> LazyLeopard, it does nothing yet...
[10:09] <djellison> I'm sure I could have got BH3 a bit longer with it :D
[10:09] <jcoxon> i was playing with the gui

[10:10] <fsphil> oh neat, you've got links to the tracker and raw data
[10:11] <djellison> What sort of launch time are we looking at?
[10:11] <jcoxon> yeah thought that would be useful

[10:11] <Randomskk> lock
[10:12] <djellison> 10:30ish maybe?
[10:12] <fsphil> yep, map is updating
[10:12] <jcoxon> djellison, yeah i guess so
[10:13] <fsphil> is the gps altitude always that jumpy?
[10:13] <fsphil> I assume the balloon isn't moving much yet
[10:13] <LazyLeopard> Got an actual frequency yet?
[10:14] <LazyLeopard> GPS altitude seems to suffer ten times the error of GPS position, if my walks in the woods are any guide...
[10:14] <SpeedEvil> not quite
[10:14] <LazyLeopard> (Ok, so I exagerate slightly...)
[10:14] <SpeedEvil> in woods is worst case for GPS alt
[10:15] <SpeedEvil> but it's a bit worse.
[10:15] <SpeedEvil> In open sky conditions.
[10:15] <jcoxon> also gps works much better when it is moving
[10:15] <LazyLeopard> Cool! The tracker's showing a predicted track?
[10:16] <Randomskk> LazyLeopard: 434.651ish
[10:17] <djellison> Why does my cat always insist on helping when I track.
[10:17] <jcoxon> LazyLeopard, yeah natrium did it last night
[10:18] <LazyLeopard> Great idea. ;)
[10:19] <LazyLeopard> Doug: It's a cat's purpose in life to demand attention especially at those times you're least able...
[10:20] <fsphil> so true LazyLeopard !
[10:20] <djellison> Remember. Dogs have owners. Cats have staff.
[10:20] <LazyLeopard> ...though they tend to do this when you're in the bath only once (or maybe twice).

[10:24] <G0MJW> Just setting up to decode. What are people using for ASCII decode?
[10:24] <jcoxon> G0MJW, we have a special program adapted from dl-fldigi
[10:24] <jcoxon> which autodetects strings and uploads them to the server
[10:24] <jcoxon> to give us the live map
[10:24] <jcoxon> G0MJW, http://code.google.com/p/dl-fldigi/
[10:25] <jcoxon> and http://ukhas.org.uk/guides:tracking_guide
[10:25] <djellison> I'm very very stupid - and I can make dl-fldigi work :)
[10:26] <jcoxon> djellison, on that note - time to upgrade your dl-fldigi :-p
[10:26] <jcoxon> still using an old version
[10:26] <jcoxon> :-p
[10:26] <djellison> 3.11.4 is the same version I see if I download.
[10:26] <jcoxon> yes but you are using r63 of dl-fldigi
[10:27] <jcoxon> we are now at r86
[10:27] <jcoxon> (we set it up to say what version you are using when it sends status updates)
[10:27] <jcoxon> so that we can debug problems
[10:27] <djellison> Well now you've done it. The new version simply dies. I run it '- it's quits 'unexpectedly' immediately
[10:28] <G0MJW> Ah - downloaded and not working Windows7....
[10:28] <jcoxon> oh poo
[10:28] <djellison> Oh hang on - wrong version
[10:29] <jcoxon> G0MJW, must admit to my knowledge we haven't tried it on windows 7
[10:29] <djellison> No - I'm right - r63 is the Leopard version. I was using the most recent version I should
[10:29] <jcoxon> how about r83
[10:29] <djellison> You want me to be experimental
[10:29] <jcoxon> sure
[10:29] <jcoxon> we've sort of done the experiemental bit now
[10:30] <jcoxon> now its not...
[10:30] <djellison> I only experiment with narcotics and alcohol. Never software. ;)
[10:30] <jcoxon> its not experimental anylonger!
[10:30] <fsphil> beta software: just say no :)
[10:31] <fsphil> most of my software is alpha, so I'm safe *g*
[10:31] <jcoxon> G0MJW, does it give any error messages?
[10:31] <jcoxon> djellison, all working for you now ;-)
[10:31] <G0MJW> No - it might be working. Not configured right perhaps. I have managed to get into RTTY modes 7 bit 350Hz ok
[10:32] <djellison> Yup - seems to be good
[10:32] <jcoxon> G0MJW, running dl-fldigi?
[10:32] <djellison> And I didn't have to re-enter my data. Which is good.
[10:32] <G0MJW> Yes. I am stuck at DL Client
[10:32] <fsphil> I only had to re-enter my lat and lng
[10:33] <jcoxon> G0MJW, so in DL Client - select orion from the drop down flight xml
[10:33] <G0MJW> Done...
[10:33] <G0MJW> But where do I enter port settings and IP data?
[10:34] <jcoxon> all done
[10:34] <jcoxon> just need to fill in your operator details
[10:34] <djellison> If you go DL Client. DL Info. It kills it. Other than that - it's good.
[10:34] <jcoxon> hmmm yeah that'll work once you've decoded a sentence
[10:35] <jcoxon> i'm having a fight with fork over that bit
[10:35] <jcoxon> i should remove it i guess till its really working
[10:35] <djellison> Ahh - i was wondering if there was an 'about this' sort of page to check I was running the right version
[10:35] <fsphil> displays here, but I just have a message about UNKNOWN in a field
[10:35] <jcoxon> djellison, thats a good idea
[10:36] <jcoxon> bascially dl info will give feedback on whether your strings are making it to the server
[10:36] <jcoxon> dl info is probably the wrong name for it :-)
[10:37] <fsphil> hehe, I've a nestbox webcam and I just realised it's playing the sound from my radio.
[10:37] <fsphil> that'll confuse some people
[10:37] <G0MJW> Right - now if we can have a bit more altitude I ought to hear it.
[10:38] Action: LazyLeopard is reminded to check the eaves for signs of avian ingress...
[10:38] <jcoxon> G0MJW, if you fill in your lat and lon details it'll plot you onto the map as a listener
[10:38] <jcoxon> http://spacenear.us/tracker/
[10:39] <G0MJW> I did - but what format? IO91JO26 or Deg, Min Sec or Decimal Degrees?
[10:39] <G0MJW> 51°36'33.14"N 1°13'37.86"W
[10:39] <jcoxon> decimal degress please :-)
[10:39] <jcoxon> and then it'll take about 10mins till it sends another status update to the server
[10:39] <G0MJW> The only one I have not got.... Calculator...
[10:39] <jcoxon> yeah apologies for the format - mathematically we find it easier to work with :-p
[10:40] <G0MJW> I ought to send you my locator class....
[10:40] <fsphil> the decimal version makes more sense to me
[10:40] <fsphil> 51.6092 N
[10:41] <jcoxon> the changes that natrium42 made to the tracker are amazing
[10:41] <jcoxon> oh and no need for NSEW
[10:41] <fsphil> 1.2272 W
[10:41] <fsphil> but verify that first, I don't know how accurate this calculator is
[10:41] <SpikeUK> Online calc > http://www.fcc.gov/mb/audio/bickel/DDDMMSS-decimal.html
[10:42] <G0MJW> - 1.2272 Yes - I was calculating.... Is West Negative
[10:42] <fsphil> yea
[10:42] <fsphil> I made that mistake last time, ended up in the north sea :)
[10:42] <G0MJW> It is not that hard - Minutes over 60 and seconds over 3600 and add up.
[10:42] <LazyLeopard> Heh
[10:43] <jcoxon> G0MJW, all working
[10:43] <LazyLeopard> It makes very little difference to me as I'm almost on The Line.
[10:43] <jcoxon> LazyLeopard, i'm -0.05 from the line
[10:43] <LazyLeopard> Even closer. ;)
[10:43] <LazyLeopard> I'm a bit over 0.06
[10:44] <jonsowman> are we still decoding ok?
[10:44] <fsphil> I visited the line once .. there really is a line :)
[10:44] <jcoxon> i can nearly see greenwich :-p
[10:44] <jcoxon> jonsowman, yup
[10:44] <djellison> My shoddy decimal puts me in the local primary school. Fortunately I'm CRB checked, so you can't ready anything into that.
[10:44] <jcoxon> fsphil, oh right now there is a green laser at night
[10:44] <jcoxon> from the observatory
[10:44] <jcoxon> very cool
[10:44] <fsphil> sounds cool - they didn't have that when I went
[10:44] <djellison> Laser - are they intending to cut the world in half?
[10:44] <LazyLeopard> ...except when you want to do some atrophotography...
[10:45] <fsphil> they keep it on all night LazyLeopard ?
[10:46] <G0MJW> Thanks fsphil
[10:46] <fsphil> G0MJW, your on the map now
[10:47] <G0MJW> Thanks - Why fly so low? Below powerlines etc?
[10:47] <djellison> I'd call that last data point 'walking it out'
[10:47] <LazyLeopard> Dunno, but I've seen it whilst driving home late on a cloudy night...
[10:47] <jcoxon> G0MJW, we haven't launched yet :-p
[10:48] <djellison> You can put three zeros on the end of that altitude in about 2hrs time :0
[10:48] <jcoxon> well its not really 'we'
[10:48] <jcoxon> going to get great photos

[10:48] <G0MJW> Ah - I thought the air was a bit still there. It is one of those days here too. When launch?
[10:48] <djellison> Any moment now I'd expect
[10:48] <fsphil> here's a thought: if the launch was timed correctly, would a balloon at 30km be able to photo the night/day terminator?
[10:49] <djellison> fsphil - Sort of. We did it about 18 months ago :)
[10:49] <jonsowman> launching soon, having lift issues
[10:49] <djellison> http://vimeo.com/1629086
[10:49] <G0MJW> OK - You do know today is a major EU UHF contest don't you? There are stations out all over Europe with large antenna systems.
[10:50] <djellison> What freq GOMJW?
[10:50] <G0MJW> All of them. SSB/CW segments.
[10:50] <G3VZV_Graham> 1296MHz and up
[10:51] <G0MJW> No! 144MHz and up
[10:51] <G3VZV_Graham> sorry:)
[10:51] <djellison> Well - they're going to get 10mw of entertaining extras
[10:54] <jcoxon> G0MJW, we often don't do too much advertising about launches
[10:55] <LazyLeopard> Hmmm... Interference possibilities the other way round?
[10:55] <jcoxon> as not everyone is as pleased
[10:55] <G0MJW> You broadcast it to the world on Twitter...
[10:55] <jcoxon> true
[10:56] <fsphil> who has priority no the 434 frequency, the license exempt users or amateurs?
[10:56] <fsphil> no=on

[10:56] <G0MJW> Go dual freq. Most idiots only have one transmitter.
[10:56] <jcoxon> fsphil, niether both are secondary users
[10:57] <jcoxon> any way we've got lots of users and a very good checksum so we should get good data
[10:57] <cuddykid> just logged on..whens the predicted launch time now?
[10:57] <jcoxon> asap
[10:57] <cuddykid> okay!
[10:58] <G0MJW> .....you know what students are like on Sunday mornings. I remember it well.
[10:58] <Randomskk> back
[10:58] <Randomskk> lol not enough helium
[10:58] <Randomskk> amosot took ut the football players
[10:58] <jcoxon> oh dear
[10:58] <jcoxon> recovered?
[10:58] <Randomskk> yes
[10:58] <jcoxon> or over
[10:58] <Randomskk> and meo helium aded
[10:59] <LazyLeopard> Ah. That explains the track that looked like flight...
[10:59] <Randomskk> about to refly
[10:59] <Randomskk> got telem back too
[10:59] <jonsowman> cool we're nearly ready to go

[10:59] <djellison> It was an awesome flight

[11:03] <djellison> I remember my concerns about camera battery life. My first flight had 100 photographs of sheep at the landing site.
[11:03] <Randomskk> 434.651
[11:03] <G3VZV_Graham> 599 here
[11:03] <SpeedEvil> I get no trail on the tracker. Also no zoom buttons.
[11:03] Action: SpeedEvil tries reloading.
[11:04] <G0MJW> Exact freq?
[11:04] <jonsowman> 434.651
[11:04] <jcoxon> got a bit of a trace now i think
[11:05] <G3VZV_Graham> 435.651.7 using USB on my 910
[11:05] <fsphil> right, time to get my yagi up
[11:05] <G3VZV_Graham> easeir than tracking satellites - no doppler..nice
[11:06] <jcoxon> yup can hear it in london
[11:06] <djellison> I can just hear it
[11:06] <cuddykid> very neat how the predicted path changes when the balloon changes course
[11:06] <LazyLeopard> Can see a faint trace (434.651) but nothing decoding yet. Getting bursts of FM interference too... :/
[11:06] <cuddykid> what aerials are you all using? yagi?
[11:06] <LazyLeopard> Beginning to decode, sort of...
[11:06] <jcoxon> shifts a bit smaller then 350
[11:06] <G0MJW> Not much here yet - but hills. Once it gets higher should be OK - 19 ele yagi
[11:07] <jonsowman> yeh shift is a bit below 350
[11:07] <jonsowman> not quite sure why
[11:07] <LazyLeopard> 10-element yagi
[11:07] <jcoxon> moxon :-p
[11:07] <LazyLeopard> Got one line in. ;)
[11:07] <djellison> 7 el yagi - it's a dual band handheld satellite Arrow antenna- but with the 2m elements removed
[11:08] <cuddykid> nice, cheers guys

[11:21] <djellison> It's locked itself down to one gps string
[11:21] <SpeedEvil> looking at
[11:21] <LazyLeopard> ...and they're talking astronomy on Desert Island Discs. ;)
[11:21] <djellison> Who is it? Brian Cox?
[11:21] <jcoxon> its to do with the crossing over the meridian line
[11:21] <Randomskk> it's lost lock
[11:21] <Randomskk> gps time not changing
[11:22] <Randomskk> not negating sats in view though
[11:22] <djellison> Oh god here - Maggie Aderin-Pocock. I find her very very annoying.
[11:22] <SpeedEvil> Randomskk: it's probably not actually lost lock
[11:22] <jcoxon> sure its not frozen because of going over 0.0
[11:22] <SpeedEvil> Randomskk: it's hit a bug in the code as it went past the meridian
[11:22] <Randomskk> SpeedEvil: code error then?
[11:22] <Randomskk> gps time is frozen
[11:22] <SpeedEvil> Randomskk: well - looking at the output anyway.
[11:22] <LazyLeopard> Hmmm... Maggie Aderian-Pocock, apparently...
[11:22] <djellison> any chance of it recovering itself?
[11:22] <G0MJW> Very strong now, probably high. Beam heading from here 45 deg
[11:22] <SpeedEvil> djellison: unlikely - it's not going to head over the meridian again
[11:23] <jcoxon> perhaps its time to fire rjmunro's bearing calculator into action
[11:23] <LazyLeopard> Heh!
[11:23] <SpeedEvil> and maybe nuke those last points from the tracker - so it shows the updated track, but nothing else?
[11:25] <jonsowman> good idea LazyLeopard
[11:25] <jcoxon> would need to stop the listener server sending data to the tracker
[11:26] <djellison> or we all just quite dl fl digi
[11:26] <rjharrison_> I can do that
[11:26] <djellison> quit, even
[11:26] <rjharrison_> Lets log I'll just stop the tracking
[11:26] <djellison> actually best not, just in case it magically recovers
[11:26] <rjharrison_> Oh it will
[11:26] <rjharrison_> Wont it blow back across
[11:26] <Randomskk> qrt, be back in a mo
[11:26] <rjharrison_> iirc the flight path
[11:27] <rjharrison_> iirc it should come back to life in about an hour or am I missing something
[11:27] <rjharrison_> oh I am
[11:27] <djellison> the flight path now, of course, is predicted from the bug-ridded false latlong
[11:28] <jcoxon> i can delete the dodgey points
[11:28] <jcoxon> but the listener server will just add more
[11:28] <rjharrison_> it's gone West already and is in negative zone

[11:32] <jonsowman> MikeMc68 and scotty are both chasing
[11:32] <SpeedEvil> IIRC it was just outside dunstable

[11:33] <djellison> Landing in the Aylesbury, Dunstable, Tring area
[11:33] <jonsowman> http://www.srcf.ucam.org/~js843/orion1.png
[11:33] <djellison> or on the M40
[11:33] <jonsowman> its actually slightly north of there
[11:34] <djellison> Tell you what - it's not drifted freq much at all
[11:34] <djellison> Must be a nice robust thermal design
[11:34] <G0MJW> It is getting really strong here.
[11:35] <jonsowman> erm its a maplin box coveredin foam and duct tape
[11:35] <G3VZV_Graham> S9+20 here :)

[11:39] <jonsowman> ok Randomskk and I will be back in a bit
[11:39] <juxta_> ah no :(
[11:39] <LazyLeopard> Was looking good. Hopefully payload is doing the right thing.
[11:39] <SpeedEvil> juxta: still transmitting strongly - so maybe yagi - it's also got a sms on landing
[11:39] <juxta_> is the lat still working?
[11:39] <SpeedEvil> juxtano
[11:39] <SpeedEvil> Oh. SMS on landing. That's not run from the same GPS/micro is it?
[11:39] <juxta_> hey SpeedEvil
[11:40] <SpeedEvil> hey
[11:40] <LazyLeopard> Nope! ;)
[11:40] <juxta_> SpeedEvil, nah i think thats seperate
[11:41] <juxta_> roughly where is it by DF SpeedEvil?
[11:42] <SpeedEvil> dunno. /me is well over radio horizon.
[11:43] <juxta_> oh righto
[11:43] <SpeedEvil> It was heading pretty much dirctly southwest, with some jiggles - on the predictor - for south of dunstable
[11:43] <LazyLeopard> Meh. I need a *decent* old fashioned compass. Direction-finding then might be half-way non-fuzzy.
[11:43] <G0MJW> Still 50 deg so heading my way more or less. Graham is closer and should have a better bearing.
[11:43] <SpeedEvil> LazyLeopard: can you see the sun?
[11:43] <juxta_> hmm
[11:43] <juxta_> hopefully the GPS code comes good or something
[11:43] <LazyLeopard> Good point. ;)
[11:43] <fsphil> what's the frequency atm?

[11:48] <SpeedEvil> It should be at ~15km
[11:48] <SpeedEvil> a way from burst
[11:48] <juxta_> anybody speak to MikeMc68? my chase car software didnt work for him by the looks :(
[11:49] <jcoxon> hmmm thats wobbly
[11:49] <G0MJW> Had to re-tune drifted down 100Hz out of the filter..still going down
[11:50] <G3VZV_Graham> the signal is 59 with an 817 and an arrow lying flat on the shack floor...amazing
[11:50] <jcoxon> that sounds like its coming down

[11:53] <fsphil> where's an earth shattering ka-boom when you need one? :)
[11:53] <SpeedEvil> where it might be right now was a bit where the predictor did a very fast little loop
[11:54] <juxta_> any bearings on it?
[11:55] <G3VZV_Graham> its so strong its difficult to track but in now seems strongest 145 el and 30 ele
[11:55] <jonsowman> any news guys?
[11:55] <G0MJW> I would say the TX battery is going flat as it is really wobbly. It is passing towards MK on my beam heading
[11:55] <G0MJW> Leighton Buzzard
[11:56] <cuddykid> what freq are we on?
[11:56] <cuddykid> do you think whip will get signal in worcester (but on top of hill) with LOS?
[11:56] <G0MJW> Freq depends when you ask - currently 434.6511
[11:57] <jcoxon> 434.650 for me
[11:58] <jcoxon> its very characteristic of descent in my opinion
[11:58] <cuddykid> cheers, will try, but doubt if i will get signal using just whip antenna
[11:58] <G3VZV_Graham> now 185 az still 30 el
[11:59] <G0MJW> Bearing still 40 +-10
[12:00] <G0MJW> Can someone adjust the tracker to put it Just south of MK?
[12:01] <LazyLeopard> Something like 310-330 from here, best I can figure, but there's no clear sight-line at ground level...

[12:13] <jcoxon> hehe
[12:13] <G0MJW> Back to about 50 from Didcot but the fading makes it hard to tell exactly

[12:31] <G3VZV_Graham> if you add the + 0.125 longtitude of cambridge to the transmitted 0.56893 does that get us anywhere near the correct location?
[12:32] <Randomskk> rjharr_mobile: payload weight was about 2.5ish kg
[12:32] <rjharr_mobile> Woooof
[12:32] <Randomskk> yea
[12:32] <Randomskk> we thought it was 2kg
[12:32] <Mike_ChaseCar> i've stopped the c ar to log ina nd check and it's now East London
[12:32] <Randomskk> underfilled it
[12:32] <rjharr_mobile> Balloon size?
[12:32] <Randomskk> Mike_ChaseCar: tracker is mirrored about somethi g
[12:32] <Randomskk> rjharr_mobile: trying to recall, would 2100 make sense?
[12:33] <rjharr_mobile> Yep unusual put possible 1500 common
[12:33] <Randomskk> 1200 apparently
[12:33] <rjharr_mobile> so total weight is ~4.5kg inc balloon
[12:33] <jcoxon> Mike_ChaseCar, the gps is broken - the longitude is wrong but latitude and altitudea are correct
[12:33] <jcoxon> bbl
[12:34] <Mike_ChaseCar> so what is the predicted landing spot ?
[12:34] <rjharr_mobile> Did you apply the rule of thirds to the para and balloon
[12:34] <rjharr_mobile> c u jcoxon
[12:34] <Mike_ChaseCar> somone just give me a name of a town or village near please
[12:34] <G0MJW> Bearing changing quickly so it is close to 90 now. Fading makes it difficult to be precise
[12:34] <Randomskk> rjharr_mobile: balloon, 10m, para, 20m, payload iirc
[12:34] <rjharr_mobile> Dont notmally give me time to say buy
[12:34] <rjharr_mobile> bye
[12:34] <rjharr_mobile> oooh
[12:34] <G3VZV_Graham> thame ish
[12:35] <rjharr_mobile> If balloon shreds and stays with the payload then it will fold the line around the 10m mark which means the payload is surrounded by balloon remains
[12:35] <G3VZV_Graham> still 220 ax now 15 ish el
[12:35] <G0MJW> J7 or J8 M40 - approx. But it depends when it pops.
[12:36] <rjharr_mobile> This is is due to the lack of friction at burst alts
[12:36] <rjharr_mobile> I mornally recommend and have a 100% sucess rate at para 2/3 and balloon obv on the end
[12:36] <Randomskk> that may be what we've done
[12:37] <Randomskk> it was 10m and 20m
[12:37] <Randomskk> in presumably the correct way around
[12:37] <rjharr_mobile> This way there is a 1/2 separation of balloon from payload and para
[12:37] <rjharr_mobile> does that make sense
[12:37] <Randomskk> think so

[12:38] <scottjames> whats the link for the landing prediction.??
[12:38] <rjharr_mobile> hey scottjames cool
[12:38] <scottjames> Thanks
[12:38] <G0MJW> What is your bearing Graham?
[12:38] <LazyLeopard> ...or maybe south of there...
[12:39] <scottjames> do u guys have an updated predictor url?
[12:39] <rjharr_mobile> Lets hope the sms works ok :)
[12:39] <rjharr_mobile> Are they independent
[12:40] <scottjames> guys i need a landing predictor corrdinates...
[12:40] <scottjames> please

[12:41] <LazyLeopard> About 320 from Orpington +/- 20 degrees)
[12:42] <scottjames> is it near aylesbury...?

[12:42] <scottjames> ?
[12:42] <scottjames> for the final destination
[12:42] <rjharr_mobile> scottjames the truth is i'm not sure anyone actually knows atm
[12:42] <G0MJW> Very strong here on my handheld but weak on the beam because of the elevation angle.
[12:42] <scottjames> so shuould i still head for high wycombe yes????
[12:43] <rjharr_mobile> The predictor won't work due to the garbled data
[12:43] <scottjames> ah...
[12:43] <G0MJW> That puts it near wallingford...
[12:43] <scottjames> well where should i head to pick it up roughly?
[12:45] <G0MJW> Currently 19000m If it bursts at say 28 it will be in Bournemouth by then.
[12:45] <jonsowman> decoding nice and strong in cambridge

[12:49] <fsphil> you and me both LazyLeopard :)
[12:50] <LazyLeopard> My Heath Robinson drain-pipe mast doesn't really cope with the breeze...
[12:51] <jonsowman> woo tracking
[12:52] <jonsowman> anything we can do about the coords being wrong? are they just mirrored about 0?
[12:52] <LazyLeopard> Come to that, an alt/az rotator would be good for satellite tracking too.
[12:53] <LazyLeopard> jonsowman: Don't seem to be, far as we could figure...
[12:53] <jonsowman> just totally wrong?
[12:53] <LazyLeopard> Is the code that decodes the NMEA listed anywhere?
[12:53] <SpeedEvil> Is the code up anywhere?
[12:54] <G0MJW> Latitude seems OK. Longitude is not right. About 1 at the moment is my estimate.
[12:54] Action: G3VZV_Graham agrees:)
[12:55] <jonsowman> ill put the code somewhere accessible now
[12:55] <jonsowman> 2 secs

[12:57] <jonsowman> scottjames: is your gps working?
[12:57] <jonsowman> <randomskk> why don't we think mirroring it about 0 gives the correct position? leads to a wrong bearing or what?
[12:57] <G0MJW> What does the NEMA string look like?
[12:58] <jonsowman> normal gpgga
[12:58] <SpeedEvil> http://aprs.gids.nl/nmea/#rmc
[12:58] <G0MJW> I wonder if you are missing the "-" If we see a change when we pass 1 we will know what is up.
[12:59] <jonsowman> I don't think the nmea has -
[12:59] <jonsowman> rather a N or S
[12:59] <jonsowman> code was untested across miridian so...

[13:00] <jonsowman> what makes us think it isn't mirrored about 0?
[13:01] <LazyLeopard> About 300-ish from Orpington.
[13:02] <G3VZV_Graham> jonsnowman - 'cos it is SW on me and I am at -0.655
[13:02] <G0MJW> OK - it is converting a float to an int... if that is negative it will have an error (I think) 1 + 1-reading?
[13:02] <LazyLeopard> jonsowman: It was something about the way it picked up after it was jammed at 52.1839,0.65532,3359 for quite a while.
[13:03] <LazyLeopard> Could try flipping it and see where that puts it...
[13:03] Hiena (~Hiena@81.93.195.181.datatrans.hu) joined #highaltitude.
[13:03] <jonsowman> have you got access to the tracker code LazyLeopard
[13:03] <jonsowman> we could try flipping it?
[13:04] <G0MJW> No - it is not that. The error is only in the lower digits.
[13:04] <jonsowman> <randomskk> flipping seems like it would put it near the predicted path
[13:04] <jonsowman> can we reverse engineer the error offset from the code?

[13:05] <jonsowman> well to refuse to lock
[13:05] <jonsowman> just have to hope it recovers after it drops below that
[13:06] <jonsowman> it has before, I am told
[13:06] <jonsowman> there we go
[13:06] <jonsowman> it has
[13:06] <LazyLeopard> Yeah, it's returning zero altitudes now.
[13:06] <jonsowman> yup
[13:06] <jonsowman> it will just keep sending that position lat/lon until it regains
[13:06] <jonsowman> last field is sats in view, should go up again once it regains lock
[13:07] <jonsowman> some time after burst
[13:07] <jonsowman> do we have an eta to burst given ascent rate?

[13:13] <jonsowman> we think so
[13:13] <juxta> ah righto
[13:13] <juxta> oh yeah that GPS module is no good above 24km, is it
[13:13] <rjharrison> At home
[13:14] <rjharrison> Still in the air?
[13:14] <juxta> seems so rjharrison
[13:14] <LazyLeopard> yeah
[13:14] <jonsowman> yeh juxta we knew that from the start, not too worried
[13:14] <juxta> yeah
[13:14] <G3VZV_Graham> yes loud and clear here even on a handheld
[13:14] <juxta> was it a code error?
[13:14] <jonsowman> clearly down to our awesome antenna:
[13:14] <jonsowman> http://twitpic.com/174t1g
[13:15] <jonsowman> juxta: not sure atm
[13:15] <rjharrison> Current freq?
[13:15] <jonsowman> 434.6505
[13:17] <jonsowman> do we still reckon this is not mirrored in the meridian
[13:17] <jonsowman> >
[13:17] <jonsowman> ?
[13:17] <G3VZV_Graham> yes we do
[13:17] <G3VZV_Graham> altitude must still be rising..now reading 30 deg ele
[13:17] <juxta> so somewhere near Oxford?
[13:18] <G0MJW> Still seems to be East of me - though the antenna elevation pattern my be suspect. If it is it must be 1W or less longitude. It is possible it is 0.577W
[13:18] <jonsowman> excuse the screwed number of satellites value
[13:18] <jonsowman> thats our fault
[13:19] <G3VZV_Graham> still west of south from of Milton Keynes 0.6555W
[13:20] <rjharrison> Nice pic
[13:20] <rjharrison> no signal here in leeds
[13:21] <russss> haha nice antenna
[13:21] <russss> colourful
[13:22] <LazyLeopard> About 290 or 300 from here in Orpington, maybe 20 degrees elevation +/10 or more...
[13:22] <SpeedEvil> Ok - it's the printing
[13:22] <SpeedEvil> lonst= (int) lon; lonend= (lon- lonst)*10000;
[13:23] <SpeedEvil> with lon at -0.5 - lt tries to print 0 (correctly) - and then lonend is set to -5000
[13:23] <rjharrison> Ok is that the formula SpeedEvil
[13:23] <SpeedEvil> sprintf(Radiostring,"$$ORION,%lu,%02u:%02u:%02u,%d.%04u,%d.%04u,%d,%u",ticks,GPShr,GPSmin,GPSsec,latst,latend,lonst,lonend,alt,sats);
[13:23] <G0MJW> Thougt it might be there but I didn't reverse engineer it. cos I could not work out lonst
[13:23] <SpeedEvil> so it's printing it as an unsigned
[13:24] <G0MJW> So we add 0.5 deg and make it negative?
[13:24] <SpeedEvil> Are the ints 16 bit?
[13:24] <G0MJW> Oh! More difficult.
[13:24] <juxta> SpeedEvil: 8 bit I think?
[13:25] <SpeedEvil> can't be
[13:25] <juxta> oh
[13:25] <juxta> no
[13:25] <juxta> yeah, sorry
[13:25] <juxta> 16
[13:25] <juxta> yeah it's 16, I remember worrying about it on my balloon
[13:25] <juxta> as it overflows at 32k on a signed int, and I thought I might pass than on alt
[13:25] <SpeedEvil> I think it will go to 32768-(value)
[13:26] <SpeedEvil> err - nbo
[13:26] <SpeedEvil> I mean 65536-
[13:26] <russss> just shove it into an unsigned and then cast it to signed :)
[13:27] <SpeedEvil> It will also do this for degrees lower than 0 - when it goes that far
[13:27] <G0MJW> Wallingford!
[13:27] <SpeedEvil> Ok.
[13:28] <SpeedEvil> (65536-57679)
[13:28] <SpeedEvil> -0.7857 degrees
[13:28] <G3VZV_Graham> now 195 az and 40 ele from MK
[13:29] <G0MJW> That is plausible.
[13:29] <fsphil> I should be hearing something by now, starting to think my antenna isn't high enough
[13:29] <Randomskk> does anyone have access to the tracker? natrium42 / jcoxon?
[13:29] <Randomskk> jonsowman: battery and laptop are on charge
[13:29] <Randomskk> jonsowman: want some crisps?
[13:29] <rjharrison> SpeedEvil do we have a formula

[13:30] <scottjames> i am near high wycombe in ayles bury
[13:30] <Randomskk> scottjames: we think we've worked out correction factor for the gps on ours, how is/was your gps doing?
[13:30] <scottjames> hows the predictor going on
[13:30] <scottjames> awesome
[13:30] <Randomskk> currently >24km altitude so our gps has cut out
[13:30] <scottjames> my gps isn't respongsing
[13:30] <scottjames> yeah
[13:31] <Randomskk> not surprised, I wouldn't expect you to get texts from 24km
[13:31] <Randomskk> was it working after launch for a bit?
[13:31] <juxta> how high did the sms work to?
[13:31] <scottjames> a little..but i think the little crash... did something
[13:31] <rjharrison> SpeedEvil PM
[13:31] <scottjames> and once seeled the cant open it
[13:31] <scottjames> :(
[13:31] <Randomskk> scottjames: ah okay
[13:31] <Randomskk> yea fair enough
[13:31] <Randomskk> hopefully cams etc were okay
[13:31] <scottjames> yeah they are fine
[13:31] <Randomskk> should have an epic failed launch video if nothing else
[13:31] <Randomskk> sweet
[13:31] <SpeedEvil> hmm. The alt seems to have frozen.
[13:31] <SpeedEvil> oh
[13:31] <scottjames> umm...what can i do now?
[13:31] <Randomskk> SpeedEvil: yea, >24km
[13:31] <Randomskk> scottjames: wait
[13:32] <scottjames> ok...
[13:32] <Randomskk> once it bursts and falls below 24km our gps should get lock again
[13:32] <scottjames> so i wait till it buursts
[13:32] <jonsowman> have we got a correction formula for the current data
[13:32] <scottjames> :) awesome
[13:32] <Randomskk> at which point we shoul dbe able to work out where it is
[13:32] <Randomskk> jonsowman: SpeedEvil seems to have worked it out
[13:32] <scottjames> that would be awesome
[13:32] <jonsowman> ah good
[13:32] <scottjames> i want thoose nice pics
[13:32] <Randomskk> 65536 - current apparently?
[13:32] <jonsowman> altitude lock
[13:32] <Randomskk> anyway going down again
[13:32] <G0MJW> Burst!
[13:32] <Randomskk> huh 23km
[13:32] <jonsowman> definite burst
[13:33] <Randomskk> looks like it's burst and on the way down
[13:33] <scottjames> it bursy?
[13:33] <Randomskk> hey jonsowman our guess was dead on
[13:33] <Randomskk> 13:30
[13:33] <scottjames> oh ok
[13:33] <rjharrison> If you get warbling on the signal then yes
[13:33] <jonsowman> Randomskk: we are good
[13:33] <rjharrison> it's very teltail
[13:33] <Randomskk> :P
[13:33] <Randomskk> sweet
[13:33] <LazyLeopard> Coming down ;)
[13:33] <scottjames> so now its burst
[13:33] <scottjames> where do i head too?\
[13:33] <Randomskk> rjharrison: can you update the tracker to apply the correction?
[13:34] <G0MJW> Princes Risborough / High Wycombe
[13:34] <rjharrison> Randomskk will try to fix asap
[13:34] <Randomskk> high wycombe is predicted landing so would make sense
[13:34] <Randomskk> rjharrison: sweet, thanks!
[13:34] <SpeedEvil> If any figure has 5 digits - negate and add 65536 I think
[13:34] <Randomskk> okay heading down to jonsowman now
[13:35] <SpeedEvil> Oh - and add a negative sign to the lat
[13:35] <scottjames> i am near high wycombe
[13:35] <scottjames> can you update http://spacenear.us/tracker/ so i can go there...... or even the landin predictor
[13:36] <jonsowman> scottjames: give us a sec
[13:36] <scottjames> ok :)
[13:36] <scottjames> 22.2 m/sec decent..parachute is kinda working
[13:36] <SpeedEvil> At -1.0304 degrees - it will read 65535 degrees, 65231
[13:36] <fsphil> it's coming down fast
[13:37] <SpeedEvil> ok - unlikely to reach 1 degree I guess - just negatethen
[13:40] <juxta> SpeedEvil: shouldnt it be something like (65536 - (long*100000))/10,000?
[13:40] <Colin__> scottjames: the parachute will work better at lower alt wont it?
[13:40] <juxta> or am I mistaken?
[13:41] <juxta> yeah it will slow right down once it reaches denser air
[13:41] <scottjames> cool
[13:41] <scottjames> umm yeah..
[13:41] <juxta> any sms's yet scottjames?
[13:41] <scottjames> umm can i get a rough heading to pick it up..as i said i am near high wycombe. checking texts now

[13:49] <scottjames> really need real path..

[13:49] <rjharrison> I can do it

[13:50] <G0MJW> lon is out by factor of 10

[14:15] <Randomskk> Mike_Chase: thatwas from the sms gps which may or may not be more accurate
[14:15] <rjharrison> Given the alt of the last pos my guess is that it is in the trees if the tracker is working

[14:17] <Randomskk> that's a reasonable amount off the predicted land spot

[14:17] <Randomskk> http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=@51.5974,-0.9939 I think is more likely to be correct
[14:17] <Randomskk> the sms one
[14:17] <SpeedEvil> that is -1 .(65536-65511)
[14:17] <Randomskk> I suspect something else up is up with the tracker gps after it mysteriously swapped
[14:18] <Randomskk> SpeedEvil: so the same bug as before after all
[14:18] <LazyLeopard> The West co-ord in that is still suffering from the unsigned flip problem after the decimal point...
[14:18] <Randomskk> how annoying
[14:18] <SpeedEvil> So -1.03
[14:18] <Randomskk> http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=@51.586,-1.03 then
[14:18] <Randomskk> seems somewhat reasonable

[14:20] <Randomskk> I think mike said his radio was offline
[14:20] <SpeedEvil> Is there a raw dump of the data as it's recieved, before processing by the server?

[14:29] <Randomskk> road gets a bit wider to one side to give you space to stop etc

[14:30] <juxta> dont know what we call that here

[14:45] <Randomskk> sweet!
[14:45] <Randomskk> nice and in the middle of a field
[14:46] <rjharrison> Will people with numbers phone scotty and let him know that it's safe
[14:46] <rjharrison> As you shit yourself a bit
[14:46] <jonsowman> does anyone actually have scott's number?
[14:46] <Randomskk> rjharrison: mikemc is at the crown pub down gangsdown hill
[14:46] <jonsowman> if not i can phone ed and get it
[14:46] <Randomskk> jonsowman: could you text ed to tell him to text scott?
[14:46] <Randomskk> if ed has his phone...
[14:46] <jonsowman> Randomskk: will do
[14:48] <jonsowman> ed is texting me scotts number anytime now...
[14:48] <Randomskk> lol okay
[14:49] <jonsowman> apparently ed was on scotts payload sms'er
[14:49] <jonsowman> so he's been getting texts all afternoon
[14:49] <jonsowman> lol
[14:49] <rjharrison> hehe
[14:49] <Randomskk> oh lol
[14:49] <Randomskk> unfortunate
[14:50] <Randomskk> must cost a bit too
[14:50] <jonsowman> haha
[14:50] <jonsowman> yeh
[14:50] <Randomskk> so the SMSs worked in the end anyway?
[14:50] <rjharrison> Cool
[14:50] <Randomskk> but so did our tracker, kind of :D
[14:50] <jonsowman> let's get the ferret back and fix the bugs
[14:50] <rjharrison> :)
[14:50] <jonsowman> then it can fly again
[14:50] <rjharrison> Yep
[14:50] <Randomskk> and test it this time
[14:50] <Randomskk> perhaps secure it to the box with more than blu tack? :P

[14:52] <jonsowman> mike is by a black nissan navara with a radio ant on the roof
[14:52] <jonsowman> is that G0MJW's?

[15:05] <Randomskk> lol uh
[15:05] <Randomskk> now off the phone
[15:05] <Randomskk> would probably have made more sense to give him willis' number
[15:05] <Randomskk> but anyway
[15:05] <Randomskk> they're on the same field damnit >_>
[15:05] <Randomskk> can you ask G0MJW to phone mikemc?

[15:06] <jonsowman> they'll find each other
[15:06] <Randomskk> shall I phone and say he's on the wrong side
[15:06] <Randomskk> okay
[15:06] <Randomskk> they'll figure it out

[15:56] <ProjectCirrus> just guess the diameter then take the lift value
[15:57] <ProjectCirrus> keep updating your diameter until you get an appropriate ascent rate then use the value of free lift the sheet says at that point

[16:01] <fsphil> working on it a bit last night, nothing yet - just sending text for the moment
[16:01] <ProjectCirrus> good start!
[16:02] <jedahan> using burst1.xls , is there a way to calculate burst height and ascension rate based on free lift alone, and ignore diameter?
[16:02] <jedahan> or should we just use a string to calculate diameter and make sure we are weighed down enough on the other end?
[16:02] <jonsowman> jedahan: not really
[16:03] <jonsowman> just play with the diameter field in the xls
[16:03] <ProjectCirrus> thats kind of what im saying... just guess a diameter and work from there keep guessing it until you get the value of free lift popping up
[16:03] <fsphil> binary search -- start small, then high, then half the difference...
[16:03] <jedahan> well we aren't aiming for a particular amount of free lift, just a particular ascension rate

[16:05] <jcoxon> i've been away from my radio since 12.30 but looks like i managed to get quite a bit of the strings
[16:06] <jonsowman> then it can fly again
[16:06] <jcoxon> jonsowman, hehe its a well known bug
[16:06] <jcoxon> i use tinyGPS lib
[16:06] <jonsowman> we might well look into that
[16:06] <ProjectCirrus> phil is it between roughly 1.2v and 1.4v
[16:06] <jcoxon> but modded a little to report sats

[16:11] <fsphil> surprisingly well
[16:11] <fsphil> though the signal is very strong
[16:11] <ProjectCirrus> do you know roughly what resistance the ntx2 pin is giving?
[16:11] <fsphil> i wouldn't expect much at distance
[16:12] <fsphil> the ntx2 has a 100k resistor internal I believe
[16:12] <ProjectCirrus> its just im building the potential divider tomorrow and its good to know so i can choose my pots appropriately
[16:12] <fsphil> I'm using a 22k and 22k+2k2+2k2 -- same as suggested on the ukhas page

[16:15] <fsphil> though it wouldn't harm
[16:15] <ProjectCirrus> very true, i just want to give as good a start as possible

[16:16] <fsphil> got both, just in case

[16:20] <ProjectCirrus> well, ive got the gps serial cable put into a 3.5mm stereo jack, so a headphone splitter should work ok, in theory only one chip will want access at a time and also ive had the smartphone and my computer read it at the same time no problem

[16:26] <edmoore> so what's the status on orion?
[16:26] <ProjectCirrus> I'm not sure, haven't been on long enough but a payload for someone was recovered
[16:27] <ProjectCirrus> i'll assume it was orion
[16:27] <edmoore> i heard it had eyeballs on it yeah
[16:27] <edmoore> not sure who found it though
[16:27] <fsphil> last I heard G0MJW had found it, but nobody else had found him :)
[16:27] <edmoore> jonsowman knew the most I think
[16:27] <edmoore> yes, that was as far as I got
[16:27] <edmoore> phoned mikemc68 who could see a car which we think was MJW's
[16:31] <G0MJW> Back home now.

[16:33] <edmoore> ok - who has the payload?
[16:35] <ProjectCirrus> ok, if we all close our eyes then whoever has it can bring it up to the front and there will be no more said

[16:41] <SpeedEvil> jonsowman: For each of lat/lon - if more than zero parts of the number, - before of agfter the point are over 10000, the number is negative. You need to seperately for both parts - subtract 65536 if the number is over 10000, and then negate the whole number (or print a minus before it)
[16:42] <SpeedEvil> in this case only lon went screwy - it would also happen south of the equator
[16:43] <SpeedEvil> to lat
[16:45] <G0MJW> Mike has the payload - not me. I have photos.

[16:50] <edmoore> cool
[16:50] <edmoore> has he made contact with scotty?
[16:51] <ProjectCirrus> i truely have no idea
[16:53] <G0MJW> What to do with pictures? Mike was waiting for Scotty who appeared to be getting progressively further and further away.

[17:09] <fsphil> lol, they duct taped the tracker on the side?
[17:10] <Randomskk> back
[17:10] <Randomskk> so mikemc has met with scotty
[17:10] <Randomskk> fsphil: the box is scott's payload
[17:10] <Randomskk> the duct tape is the thing jon and I bodged together last night
[17:10] <Randomskk> handily it worked
[17:10] <G0MJW> Yes - Note my camera is still set to BST so it is an hour out if you needed to know this.
[17:10] <Randomskk> G0MJW: thanks so much for your help, btw
[17:10] <fsphil> duct tape keep the universe together
[17:11] <fsphil> it looks well, though the iTenna didn't survive the landing :)
[17:11] <Randomskk> hehehe
[17:11] <Randomskk> not surprised
[17:11] <Randomskk> straw is not particularly resistant to plastic deformation
[17:11] <fsphil> nope lol
[17:12] <Lunar_Lander> what do you think about polyethylene balloons?
[17:12] <G0MJW> No - in fact the antenna was broken which is why is cut off mid Transmission and why it took me 15 minutes to find.
[17:12] <Randomskk> D:
[17:12] <Randomskk> ah
[17:12] <Randomskk> it properly broke?
[17:12] <Randomskk> or just deformed so much it couldn't really tx

[17:12] <G0MJW> Yes. Properly solder joint gone.
[17:13] <Randomskk> the pink bit was the driven element, the yellows ground plane radials
[17:13] <Randomskk> oh wow
[17:13] <Randomskk> that's a pretty hard impact
[17:13] <G0MJW> No - I don't think so hard. But probably dragged across the ground.
[17:13] <Randomskk> ah, fair enough
[17:13] <Randomskk> still, it survived the flight
[17:13] <fsphil> that'll do it
[17:14] <Randomskk> haha the photos look great
[17:14] <Randomskk> plenty of rocks on the landing site but at least it's a clear empty field
[17:14] <edmoore> yeah not a bad landing site
[17:15] <fsphil> and it landed the right way up
[17:15] <Randomskk> apparently his texted GPS co-ords were a fair bit off

[17:16] <edmoore> just got a text from scotty

[17:17] <DoYouKnow> what kind of parachute did you guys use?
[17:17] <Lunar_Lander> people I got a question
[17:17] <edmoore> DoYouKnow: 44" PML DuraChute
[17:18] <DoYouKnow> ok
[17:18] <Lunar_Lander> what do you think about utilizing polyethlyene balloons?
[17:19] <G0MJW> Yes. GPS error is almost as bad as AIREY vs WGS84 error.
[17:20] <DoYouKnow> Lunar_Lander, isn't that for scientific balloons?
[17:20] <edmoore> Lunar_Lander: I've never used one and know little about them, so without more information I couldn't tell you
[17:21] <edmoore> oh scrap that, I'm having a dmumb day
[17:21] <edmoore> dumb*
[17:21] <G0MJW> Why would a lunar lander need a balloon?

[17:25] <Randomskk> notably including the only thing holding it in place being some bluetack
[17:25] <edmoore> the model holding the box is doing it particularly well, I must say
[17:26] <DoYouKnow> Lunar_Lander, I can't see the point of having something float up there for so long, making recovery more difficult
[17:27] <DoYouKnow> but that's just me
[17:27] <DoYouKnow> you would need a powerful transmitting system that would upload images, measurement data, etc
[17:27] <DoYouKnow> right?
[17:27] <G0MJW> You know it could be a lot better if you had some horizontal component in the transmitted signal. Most hams have horizontally polarised antennas.
[17:28] <Randomskk> I think that mainly comes down to radiation pattern and how much ends up beamed into space? but it's a good point
[17:28] <Randomskk> yagis are easier to deal with horizontally too
[17:28] <edmoore> crossed dipoles might do it
[17:28] <G0MJW> Perhaps a quadrifilar helix?
[17:29] <edmoore> but a 1/4-wave monopole is so easy
[17:29] <Randomskk> that's the thing
[17:29] <Randomskk> that antenna today took about a minute to make
[17:29] <Lunar_Lander> sorry I have been afk
[17:29] <Randomskk> and still worked pretty well
[17:29] <G0MJW> and under a second to break
[17:29] <Randomskk> yes, that's the flip side
[17:29] <Lunar_Lander> thanks edmoore!
[17:29] <Lunar_Lander> yeah I think they are expensive too
[17:29] <Randomskk> however otoh
[17:29] <edmoore> that's not a fault with the antennas as a rule
[17:29] <edmoore> just that is was done in a hurry
[17:29] <Randomskk> better the antenna breaks than whatever it lands on breaks
[17:30] <Lunar_Lander> DoYouKnow: Actually it could be recorded in the payload
[17:30] <G0MJW> No reason not to put antenna above the payload.
[17:30] <Randomskk> G0MJW: the main issue is that the payload tends to be covered in metal foil
[17:30] <Randomskk> which I imagine would interfere
[17:30] <edmoore> yes
[17:30] <edmoore> and gps interference too
[17:30] <Randomskk> depending on desired radiation pattern I guess
[17:30] <DoYouKnow> Lunar_Lander, how would you get it back?
[17:30] <DoYouKnow> to earth?
[17:31] <Randomskk> quadrifilar helixes are fun
[17:31] <Randomskk> jonsowman has built one in fact
[17:31] <edmoore> I think a bigwheel probably has some mileage

[17:31] <Randomskk> still, hurrah! payload recovery
[17:31] <DoYouKnow> so they would stay up there
[17:32] <Randomskk> and scott's project was a success
[17:32] <Randomskk> well
[17:32] <Lunar_Lander> yeah, so you use a cutdown
[17:32] <Randomskk> he is going to have an interesting report to write

[17:32] <Lunar_Lander> but it is expensive
[17:32] <Lunar_Lander> I got an offer today
[17:32] <Lunar_Lander> 1380 GBP
[17:32] <DoYouKnow> what do the scienntific balloons use that go up to 138,000 ft?
[17:32] <DoYouKnow> polyethylene?
[17:32] <edmoore> super pressure balloons or zero pressure balloons
[17:33] <edmoore> yes, polyethylene
[17:33] <edmoore> but not off the shelf
[17:33] <edmoore> the chains are aligned in the stuff they use

[17:33] <Lunar_Lander> I read that Raven Industries doesn't sell their balloons to amateurs
[17:34] <Lunar_Lander> and Aerostar neither
[17:34] <edmoore> Lunar_Lander: hence we built our own as you can see in the links
[17:34] <ProjectCirrus> get uni backing
[17:34] <Lunar_Lander> and that 1380 Pound offer was from Global Western
[17:34] <Lunar_Lander> who made the "Sprit of Knoxville"
[17:34] <edmoore> that's *incredibly* cheap
[17:35] <Lunar_Lander> yeah ProjectCirrus I'm in touch with my prof ;)
[17:35] <Lunar_Lander> yeah
[17:35] <edmoore> mark caveizel I beleive is not making them anymore though

[17:36] <Lunar_Lander> 60,000 cu.ft.
[17:38] <Lunar_Lander> I have been given an E-Mail address for a company in India

[17:42] <edmoore|away> where are you based Lunar_Lander ?
[17:42] <Lunar_Lander> Germany
[17:44] <DoYouKnow> it's interesting... the same stuff we were learning in lab about how friction counteracts the force of gravity to prduce a constant acceleration, is the same thing that results in the velocity of a balloon being constant
[17:45] <DoYouKnow> well, 0 acceleration
[17:45] <DoYouKnow> not just constant
[17:45] <edmoore|away> equilibrium is a lovely thing. but it is in the direction of gravity in this case
[17:45] <DoYouKnow> it's just the force of buoyancy and wind resistance
[17:45] <DoYouKnow> in this case
[17:45] <DoYouKnow> that are cancelling out
[17:46] <DoYouKnow> to produce a constant rate of ascent
[17:46] <Randomskk> ^ +gravity
[17:46] <DoYouKnow> yeah

[17:48] <tonyb486> what was the 1st one?
[17:48] <edmoore|away> orion
[17:48] <tonyb486> I see
[17:48] <SpeedEvil> Which was a real dissapointment.
[17:49] <SpeedEvil> I'd hoped for some nukes, and a massive pusher plate.
[17:49] <SpeedEvil> But all I got was a balloon. :)
[17:49] <Randomskk> SpeedEvil: I'll try harder next time :P
[17:49] <Randomskk> soon as we have a flight path going over your house
[17:49] <SpeedEvil> Nukes are good for society. Plot atmospheric radiation vs internet speeds.
[17:50] <SpeedEvil> It's improved immeasurably.
[17:50] <Randomskk> yes, it is immeasurable
[17:50] <DoYouKnow> how high do regular birthday balloons go?
[17:50] <edmoore|away> maybe a couple of thousand feet
[17:50] <edmoore|away> depends
[17:51] <DoYouKnow> ok
[17:52] <DoYouKnow> well, one guy attached a bunch of ballons to his chair and floated tens of thousands of feet

[18:21] <DoYouKnow> is anyone planning on sending up a quickcam-like webcam to near-space with a good wide angle lens to do some astrophotography during daytime?
[18:22] <DoYouKnow> how would you avoid the sun though... that could burn a hole in the ccd device
[18:22] <SpeedEvil> you need something lots better than most cams.
[18:22] <imipak> (naked) webcam probably not ideal for astrophotography
[18:22] <DoYouKnow> yeah, but you can stack the photos with a webcam
[18:23] <SpeedEvil> You can see stars with a long integration time - but it requires pointing.
[18:23] <DoYouKnow> you can pick a target star and track it, then you have an aligned set of frames
[18:23] <SpeedEvil> not really
[18:23] <SpeedEvil> The noise goes down as sqrt(x) for some sorts of noise.
[18:23] <SpeedEvil> fixed panel noise is not affected by this.
[18:23] <SpeedEvil> So if you take 1000 pics - your noise is only 30 times lower
[18:24] <DoYouKnow> don't you think it would be better than the project infinity results?
[18:24] <SpeedEvil> and if you can't pick out any stars unambiguously without integration, you can't track them
[18:24] <DoYouKnow> they only saw 2 or 3 stars
[18:24] <DoYouKnow> without any significant pointing afaik
[18:24] <SpeedEvil> no idea what that was
[18:25] <DoYouKnow> so what would you recommend?
[18:25] <DoYouKnow> that wasn't a star?
[18:25] <DoYouKnow> or venus?

[18:29] <SpeedEvil> What is it - page is not loading due to stupidly heavy use of flash
[18:30] <SpeedEvil> your lens size is set by the viewing angle you want and the size of the imager

[18:30] <SpeedEvil> with webcams, this is 2mm or so.
[18:30] <DoYouKnow> no, I mean for aperture
[18:30] <SpeedEvil> Typically
[18:30] <DoYouKnow> a good lens for greater aperture
[18:30] <SpeedEvil> So you can have a 45 degree 2mm dia lens.
[18:31] <SpeedEvil> Or a 4.5 degree 20mm lens
[18:31] <SpeedEvil> or a .45 degree 200mm lens
[18:32] <SpeedEvil> you need stabilisation to take pictures of stars meaningfully
[18:32] <SpeedEvil> Find a camera that at night will take pictures of stars while you're waving it around randomly, and it will work for dark sky hooked to a balloon
[18:33] <SpeedEvil> I suspect you pretty much need an intensified camera - either solid state or otherwise
[18:34] <DoYouKnow> so you think this group just had a lot of luck involved?
[18:34] <DoYouKnow> do you think*
[18:35] <SpeedEvil> Getting the brightest stars when the camera happens to stop swinging so hard isn't too bad.
[18:35] <DoYouKnow> I was thinking the key element of their design was the decision to opt for a bigger lens
[18:35] <DoYouKnow> ah ok
[18:35] <SpeedEvil> Bigger lenses have optical limits too - the optical invariant comes into play
[18:36] <SpeedEvil> basically - with a 2mm across imager - you absolutely cannot have for a 60 degree FOV - a lens more than 2mm or so in diameter.
[18:36] <SpeedEvil> Or rather - a lens more than 2mm diameter will waste light, as most of it will miss the imager
[18:37] <SpeedEvil> similarly for the same imager, with a 20mm lens with a 6 degree FOV
[18:37] <SpeedEvil> This is a consequence of the laws of thermodynamics when you get down to it
[18:38] <SpeedEvil> Find an astrophotography forum, and ask the question about cameras you can wave around freehand at night, and take pictures with
[18:39] <DoYouKnow> probably expensive
[18:39] <DoYouKnow> whatever they are

[18:58] <Randomskk> fsphil: wait 'til you see the video
[18:58] <Randomskk> first launch attempt did not have enough helium, just bounced onto the football field
[18:58] <MikeMc68> No worries guys. It was fun and it was a great practise run for my own launch. A lot of lessons learnt.
[18:58] <Randomskk> hehe
[18:58] <Randomskk> like 'bring an actual ballast mass, not a bottle of water and some peanut butter and a wrench and hope it adds up to the same thing'
[18:59] <MikeMc68> lol yep
[18:59] <Randomskk> MikeMc68: have you got any timescale for your launch?
[18:59] <Lunar_Lander> I got an idea for a Tardigrade experimenr
[18:59] <Lunar_Lander> *experiment
[18:59] <MikeMc68> I have 18th to 28th March Annual Leave - plan is to get payload ready in that time for an early April launch
[19:00] <Randomskk> cool
[19:00] <Lunar_Lander> I found a scientist in North Carolina who works with them
[19:00] <MikeMc68> so finfers crossed in about 3 weeks
[19:00] <MikeMc68> fingers
[19:00] <Lunar_Lander> I suggested sending me two packages
[19:00] <Lunar_Lander> and one does the flight the other one not

[19:00] <MikeMc68> cool
[19:00] <MikeMc68> Anyway...... food time. Laterz
[19:00] <Randomskk> seeya
[19:00] <Lunar_Lander> and then both crossed the atlantic twice, but only one flew into the stratosphere
[19:00] <Lunar_Lander> later

[20:37] <juxta> hey MikeMc68, jonsowman
[20:37] <juxta> payload recovered ok yesterday?
[20:37] <MikeMc68> today
[20:38] <MikeMc68> yeah
[20:38] <MikeMc68> Just uploading the pics
[20:38] <MikeMc68> will have to wait for Scotty for the payload pics
[20:38] <juxta> oh yeah, same day over there
[20:39] <juxta> no luck with the car track software MikeMc68?
[20:39] <MikeMc68> my radio died - so it made no difference
[20:39] <MikeMc68> :(
[20:39] <juxta> oh bummer :(
[20:39] <juxta> flat battery?
[20:39] <MikeMc68> No it's dead - i think it's a fuse
[20:39] scottjames (~sj86@94-195-51-124.zone9.bethere.co.uk) joined #highaltitude.
[20:40] <juxta> oh right
[20:40] <scottjames> Hi all thanks for the awesome launch today!
[20:40] <MikeMc68> then to top it off - the cigarette lighter power supply adapter I took to power my laptop for the day refused to work too
[20:40] <scottjames> uploading pics now!
[20:40] <juxta> hi scottjames :)
[20:40] <edmoore|away> he's back!
[20:40] <jonsowman> hello scottjames
[20:40] <MikeMc68> So I had no laptop, no internet access and no radio - it was a clusterfuck
[20:40] <juxta> haha damn, that's a pain MikeMc68
[20:40] <scottjames> question i am have made a username on ukhas, but password taking ages to be sent to my hotmail.
[20:40] <scottjames> any chance of getting it...so i can do a page on Orion?
[20:41] <MikeMc68> Anyway.....
[20:41] <MikeMc68> Here are my pics - they are intentionally small
[20:41] <MikeMc68> http://picasaweb.google.com/EarthshineDesign09/OrionLaunch#
[20:41] <scottjames> wow awesome Mike!
[20:41] <MikeMc68> scottjames once you have you rpassword you can create your own wiki pages
[20:42] <MikeMc68> Video to follow once I have edited it (not today)
[20:42] <scottjames> very nice!
[20:42] <scottjames> looking forward to video Mike
[20:42] <juxta> oh nice, the payload had 2 cameras?
[20:44] <scottjames> yeah i put 2 in!
[20:44] <juxta> scottjames: your chute is exactly the same as mine by the looks of things, hehe
[20:44] <scottjames> one video (which is epic) Mike and edd know why lol
[20:44] <juxta> how did the pics pan out?
[20:44] <scottjames> and a still
[20:44] <scottjames> camera
[20:45] <MikeMc68> lol yeah
[20:45] <MikeMc68> i'm just taking some video stills
[20:45] <scottjames> CUSE i will send back the add on to the payload tommorw :)

[20:49] <edmoore> hi juxta
[20:49] <scottjames> lol maybe
[20:50] <juxta> were you chasing etc too yesterday edmoore?
[20:50] <edmoore> not chasing, but did help with launch
[20:50] <edmoore> today :p
[20:50] <MikeMc68> uploading some video stills now
[20:51] <juxta> it's too early here
[20:51] <scottjames> some sample flight photos are up here: http://cid-f1685fe4901686f0.skydrive.live.com/browse.aspx/Orion%20Flight%20Photos?ct=photos
[20:51] <scottjames> the video will be up soon, its really good!
[20:52] <edmoore> nice
[20:52] <edmoore> can't wait to see it!
[20:52] <MikeMc68> ooohh a bit of ice
[20:54] <jonsowman> looking good scottjames
[20:54] <MikeMc68> OK i've uploaded some video stills too - including the successful and ABORT! ABORT! Attempt 1
[20:54] <MikeMc68> http://picasaweb.google.com/EarthshineDesign09/OrionLaunch#
[20:55] <juxta> abort?
[20:55] <edmoore> http://picasaweb.google.com/EarthshineDesign09/OrionLaunch#5445997402847256386
[20:55] <jonsowman> we had a slight mishap juxta
[20:55] <edmoore> at this point the balloon started floating at 20mph sideways and 0.5m/s down
[20:55] <juxta> uh oh
[20:56] <juxta> not enough lift?
[20:56] <edmoore> couldn't weight the payload, couldn't weigh the ballast bag, so somewhat of a guess at both
[20:56] <juxta> ah right
[20:56] <fsphil> probably the most exciting thing to ever happen at a football match :)
[20:56] <MikeMc68> my pics are intentionally small - if you want the full sized version let me know
[20:56] <juxta> haha
[20:56] <edmoore> http://picasaweb.google.com/EarthshineDesign09/OrionLaunch#5445997707160814226
[20:57] <edmoore> that's the coach on the side who caught it
[20:57] <MikeMc68> he should take up goalkeeping
[20:57] <juxta> ooh, lucky, looks close to trees
[20:58] <edmoore> at least there were no power lines for it to collide with
[20:58] <MikeMc68> I like this one - right after launch - http://picasaweb.google.com/EarthshineDesign09/OrionLaunch#5445997388900733890
[20:59] <edmoore> jon is wasting no time getting to the radio
[20:59] <fsphil> perfect weather
[20:59] <MikeMc68> Yeah even when it was about 2km up you could still see it
[21:00] <SpeedEvil> I wonder how far you could track it from a good location with a modest scope with filter
[21:01] <MikeMc68> many miles up
[21:01] <edmoore> we have seen them clear as day with 60km euclidean
[21:03] <SpeedEvil> you mean eye?
[21:03] <jonsowman> yes edmoore, unfortunate picture of me running
[21:03] <edmoore> SpeedEvil: yes
[21:03] DoYouKnow (~Michael@adsl-75-4-147-33.dsl.emhril.sbcglobal.net) joined #highaltitude.
[21:03] <SpeedEvil> neat.
[21:03] <MikeMc68> Scott any idea of altitude reached yet ?
[21:04] <SpeedEvil> I suppose a big sunlit white sphere can be _very_ visible in the right circumstances.
[21:04] <jonsowman> i reckon 28k
[21:04] <SpeedEvil> depending on the background hugely.
[21:05] <MikeMc68> i'm going to attach 30 metre mylar panels to mine
[21:06] <SpeedEvil> A steerable mirror would be fun. :)
[21:06] <SpeedEvil> A 1m*1m or so panel.
[21:06] <SpeedEvil> Just some frame and some taught mylar.
[21:07] <MikeMc68> mine is going to be a 1/10 scale model of the ISS
[21:07] <fsphil> would be very dramatic just after sunset
[21:07] <SpeedEvil> MikeMc68: Booring.
[21:07] <juxta> anybody here going to be around at 00:00ish?
[21:07] <SpeedEvil> MikeMc68: MIR.
[21:07] <SpeedEvil> MikeMc68: really confuse.
[21:08] <SpeedEvil> juxta: probably.
[21:08] <SpeedEvil> juxta: if you mean the one in just over 2.
[21:08] <SpeedEvil> ? hours
[21:08] <scottjames> 2 mins and the video will be up!
[21:08] <scottjames> with music
[21:08] <juxta> nice work scottjames
[21:08] <MikeMc68> I've had an idea for a cheap balloon - no need to attach any kind of GPS, or transmitter to it
[21:08] <SpeedEvil> With the copyright holders permission? :)
[21:08] <MikeMc68> Just attach it to a 33000 metre length of rope
[21:09] <juxta> heh
[21:09] <SpeedEvil> MikeMc68: there is surprisingly light fishing twine available on ebay
[21:09] <juxta> you could probably lift 30km of fishing line
[21:09] <jonsowman> MikeMc68: yep that'll work
[21:09] <jonsowman> juxta: will it break under its own weight
[21:09] <juxta> jonsowman: good point
[21:09] <SpeedEvil> IIRC ~2GPa/ton-meter being available.
[21:09] <juxta> I'm actually planning on using fishing line for my launch today
[21:10] <SpeedEvil> Which is good for 20km IIRC.

[21:29] <scottjames> burst
[21:31] <MikeMc68> oh i see - i thought you said it did the whole thing

[21:34] <juxta> what happened scottjames?
[21:34] <scottjames> video is much nicer
[21:36] <scottjames> 20 mins to publish and its up
[21:37] <scottjames> the video is alot clearer for some reason..well al little. due to its pointing down.
[21:37] <DoYouKnow> -56C inside the compartment or outside?
[21:37] <scottjames> outside lol
[21:37] <scottjames> 25 C in compartment
[21:37] <DoYouKnow> ok
[21:37] <juxta> what temp sensor did you use outside scottjames?
[21:40] <MikeMc68> I think it was a DS18S20
[21:40] <G0MJW> Was otherwise engaged for a bit. Sorry Scottie - I was impatient and left before you arrived.
[21:41] <scottjames> lol dude i meant to email you, thank you for finding it!
[21:41] <scottjames> much appreciated.
[21:41] <G0MJW> The initial photos look like the Moller centre.
[21:41] <scottjames> your'll like the video i put up
[21:41] <MikeMc68> correct
[21:42] <jonsowman> it was indeed moller
[21:42] <G0MJW> We ran a propagation course there for many years. Churchill College.
[21:42] <jonsowman> yup
[21:43] <MikeMc68> ok i'm bushwhacked
[21:43] <DoYouKnow> if anyone knows of any clubs in the chicago area that are doing this sort of thing, it would be greatly appreciated :)

[21:51] <DoYouKnow> a "bunch of windbags"

[22:27] <G0MJW> Email it then?
[22:28] <scottjames> 100 mb
[22:28] <scottjames> ll
[22:28] <scottjames> might reupload on different site
[22:30] <scottjames> trying daily motion
[22:30] <Lunar_Lander> scottjames
[22:30] <G0MJW> Flickr - but you need to limit it to 90mb
[22:30] <Lunar_Lander> how is 009 Sound System :P?
[22:31] <Lunar_Lander> Youtube even deleted Scatman's World :(
[22:31] <scottjames> scatman's world lol
[22:31] <scottjames> its 93 mbs so its ok
[22:31] <G0MJW> Video seems 90 degrees out
[22:32] <scottjames> which video?
[22:32] RocketBoy (~Steve@217.47.75.8) joined #highaltitude.
[22:32] <scottjames> hey rocketBoy
[22:33] <RocketBoy> hiya - U got it back then?
[22:33] <G0MJW> Your video.
[22:33] <Lunar_Lander> hey RocketBoy
[22:34] <Lunar_Lander> I researched polyethylene Balloons today
[22:34] <scottjames> yeah i got it back
[22:34] <scottjames> oh well daily motion is uploading it now 13 mins
[22:35] <Daviey> scottjames: do you have the decent recorded?
[22:35] <Lunar_Lander> I found they are quite expensive
[22:36] <RocketBoy> lunar_lander: yes - much cheaper to make them yourself - with the right equipment
[22:37] <scottjames> ah no, the camera was on for the ground too long for the decent :( but it got up high
[22:37] <scottjames> 32000
[22:37] <scottjames> out of 37000
[22:37] <natrium42> juxta, try posting a position please
[22:38] <Lunar_Lander> yeah
[22:38] <Lunar_Lander> I got an offer by Mark Caviezel
[22:38] <juxta> done natrium42
[22:38] <Lunar_Lander> 1380 GBP for 60,000 cu.ft.
[22:39] <juxta> I've got to head off natrium42
[22:39] <natrium42> juxta, cheers
[22:39] <natrium42> to bed?
[22:39] <juxta> to the launch site
[22:39] <juxta> haha
[22:39] <natrium42> what's the local time?
[22:39] <natrium42> oh
[22:39] <juxta> 9:09am
[22:39] <natrium42> aah, good luck
[22:39] <juxta> thanks
[22:39] <scottjames> 8 mins left
[22:39] <juxta> I'll get on irc when I get there
[22:39] <natrium42> kk
[22:39] <scottjames> sound track better be on it
[22:41] <Lunar_Lander> RocketBoy: I got an e-mail address of some balloon plant in India too
[22:41] <Lunar_Lander> I wonder what price they'll propose
[22:42] <edmoore> G0MJW: I was at amsat yes
[22:42] <G0MJW> Hi Ed - how did exams go?
[22:42] <juxta> edmoore: how do you guys do dual balloon launches?
[22:42] <juxta> ie to avoid the string touching a balloon etc
[22:43] <edmoore> juxta: the physics takes care of it
[22:43] <juxta> so the balloons in a v configuration?
[22:43] <edmoore> unless you two balloons are perfectly identical, they should separate
[22:43] <edmoore> as they each have their own equilibrium angle where drag + line tension + lift
[22:43] <edmoore> sorry, drag + line tension = lift
[22:44] <RocketBoy> Lunar_Lander: I'd be interested in the India info - but I have had some quotes form China recently - that only worked out fractionally cheaper than the totex - and I'd rather stick with somthing we know ATM
[22:44] <Lunar_Lander> yeah of course
[22:44] <edmoore> G0MJW: they came and went - I have this year's one in 6 weeks which isn't much fun
[22:44] <Lunar_Lander> the India plant, I was told, makes cheap but sound PE balloons
[22:44] <G0MJW> Ed - Good luck.
[22:45] <Lunar_Lander> nmurali@tifr.res.in
[22:45] <juxta> edmoore: hmm, ok
[22:45] <juxta> they probably dont burst at the same time I guess though
[22:45] <edmoore> nope
[22:45] <juxta> which means if I fly 2 I could end up with a mess if only one pops
[22:45] <edmoore> G0MJW: thanks
[22:45] <edmoore> juxta: yes
[22:45] <Lunar_Lander> as for latex, I would stay with Kaymont/Totex of course
[22:46] <edmoore> juxta: a tactic is to make each of them individually positively bouyant
[22:46] <RocketBoy> Lunar_Lander: cool
[22:46] <edmoore> so you at least don't start descentding
[22:46] <Lunar_Lander> yeah
[22:46] <Lunar_Lander> I was just given this address
[22:46] <Lunar_Lander> no URL or something like that
[22:47] <juxta> edmoore: yeah
[22:47] <juxta> alright, i'm off to the launch site
[22:47] <edmoore> you're launching?
[22:47] <juxta> yeah
[22:47] <juxta> small launch
[22:48] <edmoore> scottjames: all your videos claim to be removed by the user on youtube
[22:48] <Lunar_Lander> hmm
[22:48] <scottjames> lol..shouldn't be only have 2
[22:48] <scottjames> just uploaded on dailymtion
[22:48] <Lunar_Lander> that address belongs to the "Tata Institute of Fundamental Research" in Mumbai
[22:48] <scottjames> and encoding :)
[22:50] <scottjames> publishing in progress
[22:50] <scottjames> its up!!
[22:50] <scottjames> http://www.dailymotion.com/video/xchspy_ukhas-church-hill-site-project-orio_webcam
[22:50] Last message repeated 1 time(s).
[22:50] <scottjames> sounds and all!!
[22:50] <scottjames> check it:)
[22:51] <G0MJW> If you have two balloons and one bursts the payload will decent. Then the second balloon will not burst and the payload will descend in a controlled manner. I assume this is the point.
[22:51] <Lunar_Lander> RocketBoy I also found that Raven Industries and Aerostar are quite restrictive in giving away their PE balloons
[22:51] <G0MJW> scotjames: Says Publishing in progress
[22:51] <edmoore> unless each ballon individually has positive bouyancy
[22:52] <edmoore> in which case it will continue ascending but more slowly
[22:52] <scottjames> Hope you like the vid edd, its got the crash and everything :)
[22:52] <edmoore> can't see it yet
[22:52] <edmoore> it's still processing

[22:54] <jcoxon> scottjames, all recovered?
[22:54] <G0MJW> I had assumed - incorrectly the idea of two was to lift something heavy. Yes. OK. So we can use multiple balloons to get very high and do round the world trips.
[22:54] <edmoore> still in progress here
[22:55] <edmoore> a zero pressure balloon is probably the easier strategy for that
[22:55] <Lunar_Lander> definitly
[22:55] <Lunar_Lander> what is the trick behind LDB and ULDB btw?
[22:55] <G0MJW> Yes - I understand - but you could use a bursting balloon to lift the zero pressure balloon and save on the gas.
[22:55] <edmoore> super pressure balloons, often
[22:55] <Lunar_Lander> I don't think the pumpkin shape is the secret
[22:55] <Lunar_Lander> ah
[22:55] <edmoore> it is infact the secret
[22:56] <edmoore> very much the secret
[22:56] <Lunar_Lander> I hope they'll get ULDB finally working
[22:56] <russss> the pumpkin shape is the secret to making superpressure work
[22:56] <Lunar_Lander> ah
[22:56] <edmoore> although not really a secret as there are some good papers on the subject
[22:56] <Lunar_Lander> Julian Nott used a Pumpkin to cross Australia
[22:56] <russss> seems like that's a whole different kettle of fish
[22:56] <Lunar_Lander> yeah
[22:56] <edmoore> eg the ones by Pellegrino et al
[22:56] <Lunar_Lander> Nott is cool btw
[22:56] <G0MJW> Japs used similar shapes to cross the Pacific, in the 1940s.
[22:57] <Lunar_Lander> yeah
[22:57] <edmoore> i don't think you'd save on gas with a zero pressure + bursting, unless I'm missing something. You'd have the same equilibrium volume of helium in the ZP in either case
[22:57] <scottjames> Ed its now up!
[22:57] <SpeedEvil> H2
[22:57] <scottjames> and the sound works :)
[22:57] <SpeedEvil> H2 with ZP has obvious issues.
[22:58] <SpeedEvil> but for a lift balloon
[22:58] <G0MJW> verified - but Scissor Sisters?
[22:58] <RocketBoy> scottjames: have you got co-ordinates for the landing spot?
[22:58] <G0MJW> Sorry What am I saying ....
[22:58] <G0MJW> White Stripes
[22:59] <scottjames> yeah
[22:59] <scottjames> you want them now?
[22:59] <scottjames> white stripes the start yeah
[22:59] <edmoore> wow. that's quite a mislaunch
[22:59] <G0MJW> X-files?
[22:59] <scottjames> yeah funny how the guy runs with it off the ptich
[22:59] <scottjames> pitch
[22:59] <scottjames> yeah tubular bells
[22:59] <scottjames> xfiles edition
[23:00] <G0MJW> Ah - the one album I don't have everyone else does.
[23:00] <scottjames> You guys like my spacey bit of the video at the end?
[23:00] <scottjames> i think its pretty good :)
[23:00] <jcoxon> so what was the max altitude in the end?
[23:00] <G0MJW> It is good - but still sideways on my PC
[23:01] <scottjames> i think it was 36000 meters
[23:01] <scottjames> but not sure
[23:01] <scottjames> gps broke at 25
[23:01] <scottjames> and i dont have altitude meter
[23:01] <edmoore> that's pretty high for a balloon of that size
[23:01] <edmoore> with a payload of that mass
[23:01] <scottjames> btw check out 2:50 mins into the video u see and airplane :)
[23:01] <jcoxon> scottjames, hmmm the annoying SIRF III
[23:02] <jcoxon> well done with the flight - glad it went well
[23:02] <G0MJW> Ed - but you can use less material to hold the helium for the balloon that bursts.
[23:02] <scottjames> but gps worked when it landed:)
[23:02] <edmoore> scottjames: i like the end
[23:02] <scottjames> cool :) good picture no?
[23:02] <edmoore> although you spelt 'their' wrong :p
[23:03] <scottjames> see the thames and everything
[23:03] <edmoore> G0MJW: I'm not sure how that helps, other than by getting you up their faster
[23:04] <edmoore> moreover, you'd want to jettison the latex balloon before you reached that stable point of the zero pressure, otherwise you'd lift it even higher and the zp would loose more helium that it needs to maintin neutral bouyancy
[23:04] <G0MJW> Thier - There. Their
[23:05] <scottjames> whos ding the Horus 2 launch
[23:05] <scottjames> looks cool :)
[23:05] <scottjames> doing*
[23:05] <Randomskk> hahaha the mislaunch is hilarious
[23:06] <RocketBoy> hummmmmmm
[23:06] <Randomskk> looks pretty good scottjames, nice one
[23:06] <G0MJW> Nice video. Nearly became a football. How cruse phase can the spin be reduced?
[23:06] <edmoore> some paddles sticking out would dampen it a lot
[23:07] <G0MJW> How about a notebook hard disk drive?
[23:07] DanielRichman (~DanielRic@unaffiliated/danielrichman) left irc: Remote host closed the connection
[23:07] <Randomskk> ha, the plane looks cool, great big contrail
[23:07] <edmoore> you can take that even further like we did with nova 10 - note the lack of rotation on launch - http://www.srcf.ucam.org/~cuspaceflight/media.php
[23:07] <G0MJW> Store data and act as Gyro
[23:07] <Randomskk> G0MJW: only to lose it all on landing though :P
[23:07] <edmoore> G0MJW: you need air pressure for the disc head to float off the platter
[23:08] <Randomskk> I don't want to think what happens to a hard disk that hits the ground running at 5m/s descent
[23:08] <G0MJW> Do you? I had not though of that.
[23:08] <Randomskk> that's true too I guess, it is just floating on a tiny tiny cushion of air
[23:08] DanielRichman (~DanielRic@unaffiliated/danielrichman) joined #highaltitude.
[23:08] <G0MJW> I thought they were sealed
[23:09] <edmoore> they claim to be but I've seen lots of data saying they're not
[23:09] <edmoore> I think thewy're only really sealed in as far as dust shouldn't get in
[23:09] <russss> yeah
[23:09] <russss> they have vents in them
[23:09] <G0MJW> Anyway - some or other type of spinning mass would do the same job.
[23:09] <edmoore> G0MJW: watch this space
[23:09] <SpeedEvil> They have a tiny vent.
[23:10] <russss> you'd need a pretty big spinning mass.
[23:10] <SpeedEvil> This vent is covered by a filter.
[23:10] <edmoore> G0MJW: http://vimeo.com/3803248
[23:10] Action: SpeedEvil has dissasembled >1000 hard drives.
[23:10] <G0MJW> Not so large actually.
[23:11] <Randomskk> edmoore: wow, nova 10 was pretty visible
[23:11] <scottjames> glad u guys like my video :)
[23:11] <G0MJW> Looks like a large pair of trousers
[23:11] <edmoore> Randomskk: yes. you could spot it in a field certainly
[23:11] <edmoore> I think it looks a bit like the bayeux tapestry depiction of a comet
[23:11] <edmoore> note a dual balloon launch aswell
[23:13] <G0MJW> Time for bed.
[23:13] <edmoore> snap
