[00:01] <Hibby> once I fork off lysdr and get working on aprsmap (both from gordonjcp) it'll become a much more exciting place...
[00:01] <Hibby> lysdr is a lightweight SDR we're working on, and aprsmap is a prettier/more functional aprs application we're working on... it's all exciting

[00:51] <Lunar_Lander> I sent him an e-mail
[00:51] <Lunar_Lander> I will resend
[00:51] <Lunar_Lander> wait
[00:54] <Lunar_Lander> sent!
[00:54] <Lunar_Lander> please ask him if he got it

[01:52] <natrium42> Zuph: not sure, it might be direct or through the dl-system
[01:53] <Zuph> alright
[01:53] <natrium42> you could just POST or GET the string to spacenear.us directly
[01:53] <natrium42> if you have the data available
[01:53] <natrium42> no need for extra scripts
[01:54] <natrium42> or post it to your server and spacenear.us
[01:54] <natrium42> then no db duplication is necessary :P
[01:55] <Zuph> heh
[01:55] <Zuph> We're not doing that any more
[01:55] <natrium42> ah, great
[01:56] <Zuph> I just don't know how he's posting to spacenear.
[01:56] <Zuph> I'll send him an email. He'll probably answer it before I go to bed :-p
[01:56] <natrium42> one sec
[01:56] <natrium42> http://ukhas.org.uk/projects:tracker
[01:57] <natrium42> e.g. http://domain.com/tracker/track.php?vehicle=halo&time=233720&lat=5142.8844N&lon=00007.1758W&alt=123.9&heading=40&speed=20.5&pass=yourpass
[01:57] <Zuph> I'm referring to his perlscript
[01:57] <Zuph> I'm not sure if he's divided everything out yet.
[01:57] <natrium42> you could reuse the script that sendds predictions to spacenear.us
[01:58] <Zuph> He rewrote his script to post directly to track.whitestar, without database duplication.
[01:58] <natrium42> ah, ok
[01:58] <Zuph> I just don't know enough perl to determine whether or not that script *also* posts to spacenear
[01:58] <natrium42> then what's the problem? :)
[01:58] <natrium42> ah, i see
[01:59] <Zuph> Basically, the question is, "Are *we* monitoring Spacenear, or is James?"
[01:59] <Zuph> I'll email him
[01:59] <natrium42> do you have the source code?
[01:59] <natrium42> i could take a look
[02:00] <Zuph> it's on James' github
[02:06] <natrium42> it's uploade5.pl, isn't it?
[02:07] <natrium42> uploader5.pl is posting to your server only
[02:08] <Lunar_Lander> back again
[02:08] <Lunar_Lander> hi natrium42
[02:09] <natrium42> hey
[02:13] <Lunar_Lander> I got a new styropor box today
[02:13] <Lunar_Lander> only 143 g
[02:14] <Lunar_Lander> but the pharmacist who gave me it had a "WTF?" look on his face
[02:16] <natrium42> my cat likes boxes too
[02:16] <Lunar_Lander> cool
[02:16] <Lunar_Lander> as like a "home"?
[02:16] <natrium42> yeah
[02:18] <Lunar_Lander> cool
[02:18] <Lunar_Lander> I read that you can get them at labs and hospitals too
[02:18] <Lunar_Lander> and in fact, I saw a pile of them next to a bio lab

[03:10] <natrium42> Zuph: you need to fix capitalization of "SpeedBall-1" in your index.php
[03:10] <Zuph> Re: What?
[03:11] <natrium42> different capitalization
[03:11] <natrium42> e.g.
[03:11] <natrium42> if(vehicle_names[vehicle_index] != "Speedball-1") { // WhiteStar
[03:11] <natrium42> The B should be capital
[03:12] <natrium42> same for
[03:12] <natrium42> if(burst_index != 0 && vehicle_names[vehicle_index] != "Speedball-1") {
[03:12] <Zuph> Ah, yes
[03:12] <Zuph> I was wondering why those weren't showing up :)
[03:13] <natrium42> it should remove the target marker for the prediction
[03:13] <natrium42> :)
[03:13] <Zuph> Launching tomorrow! :)
[03:13] <natrium42> yeah, i am excited

[05:38] <natrium42> zuph, sup?
[05:38] <Zuph> Trying to turn off the time labels on the altitude plot, any ideas?
[05:40] <natrium42> will look at it
[05:42] <natrium42> Zuph: what was the correct time?
[05:42] <natrium42> 5 or 7?
[05:42] <Zuph> 5
[05:42] <natrium42> ok, the db returns 7
[05:42] <natrium42> http://track.whitestarballoon.com/data.php
[05:43] <Zuph> Ah, GPS time is accurate.
[05:43] <natrium42> what timezone is server set to?
[05:43] <Zuph> UTC
[05:43] <natrium42> hmm, gps time doesn't even hyave the same minutes
[05:44] <natrium42> wait, it does for the later points
[05:44] <Zuph> GPS time reflects when the balloon *sent* the data, while Server time is some permutation of when we *recieve* data.
[05:44] <natrium42> right
[05:44] <natrium42> so the altitude graph uses server time
[05:44] <natrium42> but it's possible to switch it to gps time
[05:45] <Zuph> That would be awesome.
[05:45] <natrium42> just change the line
[05:45] <natrium42> var curr_time = convert_time(position.server_time)*1000;
[05:46] <natrium42> position.gps_time
[05:46] <natrium42> but your gps better be sending correct times! :P
[05:46] <natrium42> there were problem payloads in the past
[05:47] <Zuph> heh
[05:47] <Zuph> That doesn't use GPS at all :)
[05:47] <Zuph> A complicated system of epoch counting, and synchronized watches :)
[05:47] <natrium42> hehe
[05:47] <natrium42> oh, you can also order the points based on gps_time
[05:47] Nick change: kd0mto -> DagoRed
[05:48] <natrium42> change the other instance of server_time to gps_time in that function
[05:48] <natrium42> if it's possible that points are received by server out of order
[05:48] <natrium42> otherwise it doesn't matter

[07:28] <natrium42> what about altitude?
[07:28] <jcoxon> cause you get new attempt every 10mins
[07:28] <jcoxon> still working on that
[07:29] <Dan-K2VOL> nice email James

[07:32] <Dan-K2VOL> I surely should, but the most avoided, distasteful part of the mission falls to me, the comm controller programming
[07:32] <fsphil> cool, both flights are on southgatearc
[07:32] <Dan-K2VOL> I've had to help everyone get their bits up to speed, and now mine is left
[07:32] <jcoxon> Dan-K2VOL, should we clear your track.whitestarballoon data?
[07:32] <Dan-K2VOL> we're not done simulating
[07:32] <jcoxon> oh right
[07:32] <Dan-K2VOL> well, you can clear what's in there
[07:33] <Dan-K2VOL> I don't need that
[07:33] <Dan-K2VOL> I'll be letting it run more
[07:33] <jcoxon> remember you'll need to restart my uploader5 script if you want it displayed as its all based on epochs
[07:34] <Dan-K2VOL> ah, I think brad's in charge of that
[07:34] <jcoxon> okay
[07:34] <jcoxon> no worries then
[07:34] <Dan-K2VOL> I just need the numbers for my bit

[08:42] <fsphil> sometime after 9:30
[08:44] <fsphil> assuming no problems ;)
[08:45] <fsphil> they're in glasgow at the moment -- I think the launch site is further south than that

[09:05] <Yonas_> hi there
[09:05] <fsphil> hiya Yonas_
[09:08] <Yonas_> fsphil, you tried transmit images during flight, yeah?
[09:08] <fsphil> yep, sorta successfully too
[09:10] <Yonas_> "ntil the harder than expected landing destroyed the board" cause wrong parachute diametr?
[09:11] <Yonas_> on first launch
[09:11] <fsphil> aah, that was because the parachute and the remains of the balloon got tangled up on the way down
[09:12] <fsphil> the parachute was quite small that flight but it should have came down a lot slower than it did
[09:12] <fsphil> but still, everything else survived

[09:14] <chembrow> while not rsADUserInfo.EOF
[09:15] <chembrow> oops, wrong window :p
[09:15] <fsphil> that was taken with the main camera, we only got those back after the landing
[09:15] <Yonas_> and where can i see transmited pictures?
[09:16] <fsphil> the first 10 or so images here: http://www.flickr.com/photos/fsphil/sets/72157623870036944/with/4526389672/
[09:16] <fsphil> they're mostly incomplete because of a flaw in the early version of the code
[09:17] <fsphil> also a couple of images on the second flight: http://www.flickr.com/photos/fsphil/sets/72157624515320914/
[09:17] <fsphil> it worked much better that time, but the signal was a lot weaker so there are less images

[09:18] <mattltm-alt> Hi all :)
[09:18] <chembrow> morning
[09:18] <fsphil> so hopefully the third time everything will work :)
[09:18] <fsphil> morning matt!
[09:20] <Yonas_> fsphil, third hardware will be the same?
[09:20] <fsphil> yes - identical to the last one, but with a better antenna and a few more improvements to the image code
[09:22] <Yonas_> figure of antenna?
[09:23] <fsphil> this is a picture of it before I installed it: http://www.flickr.com/photos/fsphil/5431825038/
[09:24] <Yonas_> and how did u get altiti\ude? GPS?
[09:24] <fsphil> the loose wires are straightened out
[09:24] <fsphil> yea, gps
[09:25] <Yonas_> model of gps receiver?
[09:25] <fsphil> that was an fsa03, but next time it will be something different
[09:25] <fsphil> probably a gpsbee
[09:26] <chembrow> fsphil is that just a 1/4 wave ground plane?
[09:26] <fsphil> yep chembrow, just made out of some coax
[09:26] <chembrow> (I've been learning about antennas lately :)
[09:26] <chembrow> nice. have to remember that method
[09:27] <chembrow> I went a bit overkill and etched a bit pf PCB to act as the centre mounting plate on mine
[09:27] <chembrow> http://www.flickr.com/photos/chrishembrow/5522985480/
[09:28] <chembrow> it was a slow weekend
[09:28] <fsphil> oh that's cool
[09:28] <fsphil> needs more leds :)
[09:28] <Yonas_> chewbrow, what about radiation pattern?
[09:28] <chembrow> maybe next time. is there enough RF propogation to drive a few?
[09:29] <chembrow> Yonas_ I don't think it's got enough mass to affect that, but then I could be wrong
[09:29] <fsphil> doubt it :)
[09:30] <chembrow> I figured that if a plain piece of copper worked for ferret (http://www.hexoc.com/pages/hab/ferret.php) then this should be OK
[09:30] <Yonas_> as for me, in my next launch i will use 1/4 loop horyzontally
[09:31] <Yonas_> cause radion maximum direct to horizont
[09:31] <fsphil> yea it worked really well for ferret
[09:32] <chembrow> Yonas_ how will that work for the chasers who will be closer to the payload? or are you looking for a long-distance flight
[09:32] <Yonas_> yes, long distance
[09:33] <chembrow> nice
[09:33] <Yonas_> and i will ask to try receive signal ham neighbors
[09:34] <Yonas_> that one I will make http://users.tpg.com.au/users/ldbutler/VHFLoopAntenna.htm
[09:35] <Yonas_> and it will be used as part of framework for parachute

[10:12] <Hibby> hola
[10:12] <mattltm-alt> Im back :)
[10:12] <fsphil> re re
[10:12] <fsphil> evil deeds completed?
[10:13] <mattltm-alt> Yes.
[10:13] <mattltm-alt> I've just been donated 10 original xbox's
[10:13] <chembrow> beowulf cluster?
[10:13] <Hibby> aaace
[10:14] <mattltm-alt> Thats what im thinking.
[10:14] <SpeedEvil> Beowulf isn't useful.
[10:14] <fsphil> build farm
[10:14] <mattltm-alt> Would a 10 node cluster be useful to this community?
[10:14] <chembrow> are they chipped?
[10:14] <mattltm-alt> Nope. Original
[10:14] <SpeedEvil> I mean - it's generally pointless to use a cluster if the machines are too slow, as rthre electricity costs less than a modern machien
[10:14] <chembrow> SpeedEvil not useful, but what else would you do with a boat load of surplus equipment
[10:15] <SpeedEvil> chembrow: ebay.
[10:15] <russss> yeah 10 original xboxes are probably about as powerful as a modern dual-core CPU these days.
[10:15] <mattltm-alt> fsphil: My restraining order prevents me going within 10Miles of a farm. :P
[10:15] <fsphil> moo .. I mean .. oooh
[10:15] <chembrow> I'd probably chip them and turn them into MythTV front ends
[10:15] <russss> I used to use an original xbox for XBMC but they're too slow to decode HD
[10:15] <mattltm-alt> I'm tempted to cluster them and stick thim in the data centre on the end of a 1GB pipe.
[10:16] <chembrow> russss I only use HD content on my main server; I record SD so they'd be fine for that
[10:16] <Yonas_> fsphil http://www.kyes.com/antenna/navy/rpatterns/antena03.gif
[10:16] <mattltm-alt> With all 10 clustered, its 7.28Ghz of processing power.
[10:16] <fsphil> there doesn't seem to be a decent software h.264 decoder for linux yet that can decode HD in real-time
[10:16] <chembrow> I currently use via epia mini-itx boxes, but they're rather slow
[10:17] <chembrow> fsphil ffmpeg works OK
[10:17] <mattltm-alt> Maybe I could make it a dedicated SETI cluster?
[10:17] <Hibby> mattltm-alt: with that many gig0rhertz, how can you say no?
[10:17] <fsphil> I couldn't get it working chembrow, though that was a few months ago. there may be updates
[10:18] <fsphil> it played BBC HD, but struggled - would pause quite a lot
[10:18] <SpeedEvil> What's teh CPU in original xboxe - it's around 500MHz isn't it?
[10:18] <mattltm-alt> Looking on ebay, i'm tempted to buy some and see how big I can make it!
[10:18] <chembrow> fsphil on my Fedora and CentOS MythTV servers it plays OK, with no hand of to GPU. that's on AMD X2-5200+ 4gb ram
[10:19] <SpeedEvil> Contact your power company. You may be able to get renewable energy credits for not turning it on. :)
[10:19] <mattltm-alt> Looks like you can pick up an original xbox for £10 - £15
[10:19] <chembrow> SpeedEvil thought it was 800mhz - still not much tho
[10:20] <mattltm-alt> SpeedEvil: My power costs 3p pKwh and I dont pay the bill :)
[10:20] <russss> 733MHz
[10:20] <mattltm-alt> Each xbox has a Intel Celeron/P3 733 MHz
[10:20] <russss> generally a CPU of that era needed at least a GHz to decode HD
[10:21] <mattltm-alt> 64Mb ram and 10Gb HD
[10:21] <chembrow> urh, celery
[10:22] Action: SpeedEvil connects an extension cable to mattltm-alt's sockt.
[10:23] Action: SpeedEvil sighs.
[10:23] <SpeedEvil> mattltm-alt: I thought you were in the UK?
[10:23] <SpeedEvil> 3p/kwh is well below what I've seen for electric - at least for non night-rates.
[10:24] <mattltm-alt> I like the idea but when you compare a cluster of 10 xboxes running at 7.28Ghz with my current cluster of 8 x P4 3.4Ghz running at 27.2Ghz......
[10:24] <mattltm-alt> Not worth the time.
[10:24] <mattltm-alt> May as well put another 8 into my current cluster :)
[10:24] <SpeedEvil> And oodles more RAM
[10:24] <mattltm-alt> SpeedEvil: I am :0

[13:45] <jonsowman> hi Josh__
[13:45] <Josh__> Hey Jon! How you doing?
[13:45] <jonsowman> very well thank you, yourself?
[13:45] <Josh__> yeah good thanks, got a question for you so will pm you
[13:46] <Josh__> but also have a genreal question for everyone
[13:46] <jonsowman> sure
[13:46] <Josh__> on payloads....and how to seal them? should insulating glue be required or something?
[13:47] <jonsowman> they need not be entirely watertight, otherwise you'll get lots of condensation inside
[13:47] <jonsowman> it's more important that things stay warm, especially the radio
[13:47] <Josh__> true, howhave you sealed yours previously
[13:47] <Josh__> good old friend gaffer tape? :D
[13:48] <jonsowman> pretty much
[13:48] m1x10 (m1x10@ppp046176109156.dsl.hol.gr) joined #highaltitude.
[13:48] <jonsowman> certainly for cameras, experience says to leave the lens open to the elements rather than try and seal it
[13:49] <Josh__> yeah, you wouldnt think it would be that way but i guess so
[13:51] <Darkside> it works really well
[13:51] <Darkside> except when you land in water
[13:51] <Darkside> and destroy a GoPro HD Hero
[13:52] <fsphil> ain't they waterproof?
[13:52] <Darkside> only in thise cases
[13:52] <Darkside> those*
[13:52] <fsphil> ah
[13:52] <Darkside> and we didn't use the case
[13:52] <Darkside> plus juxta cut a hole in the case for a usb connector (external power)
[13:52] <jonsowman> D:
[13:52] <fsphil> eek!
[13:52] <Darkside> so yeah, that was Horus 8...
[13:53] <Josh__> how did you attach the payload to the string on the end of the balloon?
[13:53] <chembrow> jonsowman I put a skylight filter in front of the camera lens on my payload - it would be best to remove that?
[13:54] <chembrow> I was trying to keep it sealed for warmth
[13:54] <jonsowman> generally people recommend not putting anything in front of the camera lens
[13:54] <jonsowman> they always mist up
[13:54] <m1x10> Hi all
[13:54] <fsphil> ello m1x10
[13:54] <chembrow> OK. will re-visit that then
[13:55] <junderwood> you don't need to worry about convection - there's no air.
[13:55] <junderwood> If you have a small hole for the lens there isn't much space for radiation
[13:55] <jonsowman> indeed
[13:55] <chembrow> about 50mm diameter
[13:56] <jgrahamc> GAGA-1 parachute test: yep, those are my grey hairs: http://www.youtube.com/watch?v=DdSX5pUCXRs
[13:56] <jonsowman> should be fine :)
[13:56] <chembrow> might revisit the entire payload container anyway. it's make from 50mm home insulation ATM and it's a little heavy - 600 grams empty
[13:56] <SpeedEvil> You can do it so it won't mist up on ascent. Totally sealed, dry nitrogen fill, maybe heated window
[13:56] <jonsowman> jgrahamc: are you still using the CUSF hourly predictor?
[13:56] <SpeedEvil> But ...
[13:56] <jonsowman> chembrow: yeah that's quite heavy
[13:56] <jgrahamc> jonsowman: I am using it (mainly because I'm trying to find a weekend for launch), but feel free to change the parameters if you need to.
[13:57] <jonsowman> OK no problem, I will definitely need it next week, but it can stay as it is for a while :)
[13:58] <jgrahamc> Change it when you need to. I only need a rough idea of "is this Sunday even possible"?
[13:58] <jonsowman> OK sure :)
[13:58] <jonsowman> thanks
[13:58] <jgrahamc> And the current answer is... no
[13:59] <chembrow> jonsowman yeah, I was very surprised. it doesn't feel that heavy in the hand, but according to my kitchen scales ...
[13:59] <chembrow> http://www.flickr.com/photos/chrishembrow/5555963966/
[13:59] <jonsowman> that is very neat and well made though
[13:59] <jonsowman> impressive
[14:00] <chembrow> thanks.
[14:00] <SpeedEvil> I bet half the weight is the tape.
[14:00] <chembrow> :)
[14:00] <chembrow> only bit I wasn't sure about, before weighing it, was if I needed to give the GPS antenna clear air above it - not had chance to take it outside and test it yet
[14:01] <jgrahamc> I'm using a ready made box which weighs 200g: http://blog.jgc.org/2010/09/gaga-1-capsule.html
[14:01] <jonsowman> very nice
[14:01] <jonsowman> similar to the one we launched Nova 18 in
[14:01] <jonsowman> if not exactly the same

[14:05] <jgrahamc> Yes, chembrow's antenna is really nice. Mine is made from cut up coat hangers.
[14:06] <chembrow> mattltm thanks - it was a quiet weekend
[14:07] <chembrow> I just hope it performs
[14:07] <fsphil> plenty of testing :)
[14:07] <chembrow> it works really well from the back garden to my study :)
[14:09] <fsphil> you could do that without an antenna ;-)
[14:09] <chembrow> yup
[14:10] <fsphil> predictions for a launch here are still bad, all ending up in the irish sea or scotland
[14:10] <jgrahamc> I did a test of my antenna etc. the other weekend over a reservoir: http://blog.jgc.org/2011/02/gaga-1-flight-computer-testing.html Coat hanger FTW!
[14:14] <fsphil> suppose I better go back to work :)
[14:14] <NigeyS> yeah stop skyving phil :P

[14:16] <jonsowman> yes indeed
[14:16] <NigeyS> will the IRD's go on this flight Jon ?
[14:17] <jonsowman> NigeyS: yes indeed, a new set
[14:17] <NigeyS> great! can't wait to see the results
[14:17] <jonsowman> a new design by Centronics that should cope with the pressure better
[14:17] <jgrahamc> IRD?
[14:17] <NigeyS> ah yes i remember you mentioned that
[14:17] <jonsowman> ionising radiation detectors
[14:18] <jonsowman> geiger-muller tubes effectively
[14:18] <jgrahamc> Ah. Haven't messed around with those for a long time.
[14:19] <jonsowman> they flew on Apex II last time
[14:19] <NigeyS> they can give you a fairly nasty shock iirc
[14:19] <jonsowman> but one failed before launch, the other failed at altitude for unknown reasons
[14:19] <jgrahamc> About as much as a camera flash capacitor <-- speaks from experience.
[14:19] <jonsowman> NigeyS: indeed, they're running from a 600V supply
[14:19] <NigeyS> lol that sounds unpleasant!
[14:19] <jonsowman> in fact they are powered from a camera flash inverter
[14:19] <NigeyS> oo higher than the one's ive seen previously, i think they were 400v
[14:20] <jgrahamc> It was nasty. I dismantled the camera for GAGA-1 so I could drill a hole through it and... zap.
[14:20] <NigeyS> ouch :(
[14:20] <NigeyS> jonsowman, do you forgoe the "harmless" part of the payload box message when carrying IRD's ?
[14:21] <Josh__> jgrahamc: where did you get your parachute from? :)

[14:21] <Josh__> great blog by the way!
[14:22] <jonsowman> NigeyS: nope, the Apex II payload was designed to carry them from the start
[14:22] <jonsowman> so the launch will be the IRDs plus everything else
[14:22] <jgrahamc> It's from Sperachutes: http://blog.jgc.org/2011/02/gaga-1-parachute.html
[14:22] <NigeyS> oh brill, looking forward to it :-)
[14:22] <Josh__> thanks!
[14:22] <jonsowman> NigeyS: Apex II was primarily designed for the IRDs and uplink testing
[14:22] <jgrahamc> jonsowman: are you planning to launch from Churchill?
[14:23] <jonsowman> jgrahamc: yes
[14:23] <jgrahamc> Ha. So we might well end up launching the same day if we're both weather dependent.
[14:23] <Dan-K2VOL1> ah weather
[14:23] <NigeyS> hey Dan !
[14:23] <jonsowman> indeed
[14:26] <Josh__> jgrahamc: where can i find all your posts about GAGA-1 on the blog?
[14:27] <jgrahamc> There's a 'gaga' label which takes you to: http://blog.jgc.org/search/label/gaga
[14:27] <jgrahamc> From there they are all interlinked (I've tried to make sure that you can click through to relevant stuff from each post).
[14:28] <jgrahamc> There's no single GAGA-1 blog post, perhaps I should make one.
[14:28] <jgrahamc> Would probably be a good idea to have a single index of them all somewhere.
[14:29] <Josh__> thanks!
[14:29] <jgrahamc> Or do this Google search: http://www.google.co.uk/search?client=safari&rls=en&q=gaga-1&ie=UTF-8&oe=UTF-8&redir_esc=&ei=A1WLTcT6J8uFhQftxMTBDg#sclient=psy&hl=en&client=safari&rls=en&q=intitle:gaga-1+site%3Ablog.jgc.org&aq=f&aqi=&aql=&oq=&pbx=1&fp=a08c652451654ca7

[14:31] <jgrahamc> Caveat emptor: GAGA-1 hasn't flown yet, so all of this is unproven.

[14:39] <Josh__> guys my camera uses a lithium ion type k bettery....obviously it's not going to power the camera for long enough....is there an adaptor that allows me to use an external battery whilst it stills thinks the original battery is in place? i would run an external battery through USB but i'm worried that it'll interpret the USB as a connection to a PC instead of power.
[14:40] <jonsowman> we built a switch mode regulator and connected it directly to the battery contacts on the camera
[14:41] <jonsowman> for Apex II we tried using the li-ions, but they weren't great
[14:41] <jonsowman> so using the reg for the upcoming launch

[15:26] <fsphil> I only received one string from it groupo, on the way down. didn't know it had been launched :p
[15:26] <groupo> yeh i think that was the string we got too, at 13.07, was the last position we got
[15:28] <fsphil> yea
[15:28] <fsphil> odd
[15:28] <groupo> yeh, its frustrating
[15:28] <fsphil> I was just heading out when I first heard the signal, I recorded it - there may be a few more strings there
[15:28] <fsphil> but that was during ascent, it won't help narrow down it's landing position
[15:29] <fsphil> any idea what happened? it seemed quite a strong signal,, though it was moving around a lot
[15:32] <groupo> we are not really sure, it seemed to be working fine, then has now cut off
[15:32] <fsphil> where you able to track it on the way up ok?
[15:32] <groupo> what were the last gps cordinates you found on its location?
[15:33] Simon-MPFH (~simon@phantom.mpfh.co.uk) joined #highaltitude.
[15:33] <groupo> yeh, we tracked fine up to about 20km, but cut down was meant to be at 25km, and we then lost contact about then
[15:34] <fsphil> where you following it at all?
[15:34] <fsphil> last string I got --> $$STRATHAB1,81,13:07:29,55.538799,-2.6283400,17271
[15:34] <fsphil> there was a CRC error on it though, one or more values could be wrong
[15:34] <groupo> yeh, a car load of guys are out now heading to where we think it is to try radio
[15:34] Nick change: sconklin -> sconklin-afk
[15:34] <fsphil> righty -- it should still be transmitting hopefully, if they get near it they may get the signal again
[15:35] <fsphil> it travelled a pretty good distance
[15:35] <groupo> yeh i know, at risk of being in sea
[15:35] <groupo> that string you have is last we know of it
[15:35] <fsphil> not much risk I don't think
[15:36] <fsphil> I'm pretty confident it made land
[15:36] <fsphil> the signal after that last string was intermittent -- I did get a few altitudes but no positions
[15:36] <groupo> ok, good
[15:36] <groupo> what altitude?

[15:40] <groupo> it is in the area predicted
[15:40] <jonsowman> yeah
[15:40] <jonsowman> it should be very, very close

[15:53] <mattltm> Thats gona make a mess :(
[15:54] <jgrahamc> Of course, those altitudes could be wrong given that there were errors in the received strings.
[15:54] <groupo> yeh, its coming down fast, unless error

[15:59] <groupo> im not sure where sourcecode is,
[15:59] <groupo> that would be useful though
[16:01] <jgrahamc> Guessing from the received strings it looks like it travelled 7.8km during that same time period.

[16:02] <jgrahamc> To hit the ground it would have taken a further 1,015 seconds of flight. That would put it 19.39km from where it was last seen.

[16:04] <groupo> a ha,
[16:04] <groupo> how did you work out the 19.4km? from the predictor tool?
[16:05] <jgrahamc> That puts it just inside England in the Northumberland National Park (north end). Somewhere near Hethpool.
[16:05] <jgrahamc> No, I assume constant horizontal speed, constant vertical speed.
[16:05] <jgrahamc> Then fiddled around with Google Maps. Gotta run to a meeting

[16:06] <fsphil> m1x10, it's not available -- at least not the current version
[16:07] <fsphil> also with the denser air near the ground, the descent speed likely decreased before landing

[16:40] <junderwood> groupo, don't believe landing predictions based on constant vertical speed. It will slow down significantly as it gets lower.
[16:41] <junderwood> and thus drift further
[16:41] <groupo> where do you think it might be then
[16:41] <groupo> ?
[16:41] <groupo> we are looking in the hethpool area around jedburgh
[16:42] <junderwood> dunno. not looked at your numbers.
[16:42] <junderwood> If you can give me two positions and altitudes I will have a look in a bit
[16:42] <groupo> the radio doesn't have a big range, unless we can gain a bit of height
[16:42] <groupo> so i think a lot of luck will be involved for us to find it!
[16:42] <junderwood> If it's on the ground you have to get pretty close to get a signal.
[16:43] <junderwood> With luck it's in a tree.
[16:43] <junderwood> Easy to find but less easy to retrieve

[17:17] <Hibby> hola
[17:18] <Zuph> mattltm: I think so. There's also an SPI interface that isn't too well documented.
[17:18] <Zuph> That's how you get NMEA out, anyway

[17:26] <Hibby> what's the prediction of speedball approaching UK shores tonight? Times/locations?
[17:26] <DanielRichman> mattltm: It doesn't matter, because dl-fldigi configures it automatically
[17:27] <mattltm> So no performance diferance?
[17:27] <DanielRichman> where automatically is, you tell someone in advance which one you're using and it's set up in the list so that hwen people select your payload it uses the correct settings

[17:27] <DanielRichman> mattltm: well technically 7ascii is slightly faster, but it's not noticable

[17:29] <Zuph> Hibby: Heh, Well, if you're feeling hacky, some enterprising individuals have hacked the downlink format for orbcomm sats :)
[17:29] <Hibby> orly?
[17:29] <Hibby> see what happens when I got to enterprise conferences for a day?!
[17:30] <Zuph> Yeah. Orbcomm sats downlink somewhere between 149-151
[17:30] <Zuph> GMSK, I believe
[17:30] <Hibby> curious indeed. We're talking about using GMSK for one of our next sats... the spec has a 1Mbit link on it :)
[17:31] <Zuph> Heh, the Orbcomm birds are quite a bit slower
[17:31] <Hibby> (UKube 1... it's how we're going to downlink the high res images)
[17:31] <Zuph> 2400 baud to the bird, 9600 from, IIRC
[17:31] <Hibby> the size of the dish we need is ridiculous... going to EADS Astrium 'down south' to look at their 12m S-Band dish for specs...
[17:32] <Zuph> Yuck
[17:32] <SpeedEvil> Lasers!
[17:32] <Hibby> I think the minimum would be 3m diameterish, can't remember. I got bored in that telecon... pedantic engineers being boringly pedantic
[17:33] <Zuph> the orbcomm ground stations would fit on a semi-trailer, and the sats are about 50kg, iirc

[19:27] <Blackover> Anyone can explain?
[19:29] <fsphil> heavier payloads need a larger balloon to reach a certain altitude
[19:30] <fsphil> well, that's not strictly true
[19:31] <fsphil> my explanations tend to make things more confusing :)
[19:33] <Blackover> and i also think that it's not strictly true
[19:35] <DanielRichman> Blackover: heavier stuff - you have to put more helium in it to make it fly, so there's more helium inside it. Which I think will make it expand faster/expand to a larger size at a certain external pressure compared to a balloon with less He in
[19:35] <fsphil> a balloon with a heaver payload will rise slower than the same balloon with a lighter payload, but both will burst at the same time
[19:35] <spacefelix> ...
[19:35] <fsphil> right I really am confusing things now, I'll shush :)
[19:35] <Blackover> but use the same ballon with the same amount of helium
[19:36] <spacefelix> Ja.
[19:36] <spacefelix> Assuming the same quantity of helium, both light and heavy payloads will burst at the same altitude.
[19:36] <spacefelix> Same quantity = same internal pressure.
[19:36] <spacefelix> But as the uplift force is the same for both, the heavier balloon will ascend slower.
[19:37] <spacefelix> But if you put more helium in the heavier payload balloon.
[19:37] <spacefelix> The larger quantity makes for a higher internal pressure.
[19:37] <Blackover> but there http://habhub.org/predict/ not
[19:37] <spacefelix> And therefore it will burst at a lower altitude.
[19:38] <spacefelix> However, it will ascend at a faster speed since it has more uplift force.

[21:48] <Hiena> SpeedEvil, ultralight immediate glider and motorglider concept. Basically a tube and fabric homebuilt plane.
[21:50] <Hiena> Here the most gliders used for a training older than 30 years, and there is a really big gap between the trainer and the competition gliders.
[21:50] <SpeedEvil> Hiena: Awesome.
[21:51] <SpeedEvil> If I had energy and funds, I'd want to make an ultralight fapping machine.
[21:51] <SpeedEvil> flapping
[21:52] <SpeedEvil> The pilot sits at the centre of mass, and the engine and wings are displaced oppositely up and down, to generate a flapping motion.
[21:52] <Hiena> The most novice pilot should wait long times until, they could gain flighthours. The idea is making something dirt cheap, light, single seat plane, with a decent glide ratio (around 20).
[21:53] <SpeedEvil> It would have better performance if you displaced the pilot along with the engine, but then it would also be jet propelled by vomit.

[22:27] <Darkside> cool
[22:27] <Darkside> i'll be watching
[22:27] <natrium42> but you can see mission control on ustream
[22:27] <Laurenceb> icanhazwhitestarlaunch?
[22:28] <natrium42> it's a pretty hardcore mission control too
[22:28] <natrium42> with a huge projection screen
[22:28] <Laurenceb> did someone say ipad2?
[22:28] <Laurenceb> ewww
[22:28] <NigeyS> haha you got 1 then natrium42
[22:28] <natrium42> Laurenceb: i need to sell my ipad1 now
[22:28] <natrium42> do you want it? :D

[22:28] <natrium42> barely used etc
[22:28] <MNSP> did our friend just leave for a 5 min wee
[22:29] <Laurenceb> enjoy your garden walls
[22:29] <NigeyS> i'll buy it, if only to send it back to mr jobs with a nice letter of complaint about his walled garden :p
[22:29] <Hibby> our department spent a long time considering developing a satellite/cubesat tracking app
[22:29] <natrium42> Laurenceb: it's nice to read scientifict papers on, though
[22:29] <natrium42> you should try it
[22:29] <Laurenceb> so, if there a whitestar ustream?
[22:29] <Laurenceb> that is true
[22:29] <natrium42> you can mark up with touch pen
[22:30] <Laurenceb> nut you can use an ebook reader for that
[22:30] <Hibby> and thus, I would have had free ipadness. Sadly, it wasn't meant to be
[22:30] <natrium42> search whitestar on ustream.tv

[23:08] <fsphil> We can probably get a few people on global tuners
[23:09] <jcoxon> is 40m open?
[23:09] <NigeyS> was open on the chart earlier
[23:09] <jcoxon> good good

[23:09] <jcoxon> we are going to need more listeners

[23:39] <LazyLeopard> is that 7.102 LSB?
[23:39] <jcoxon> USB
[23:39] <jcoxon> apparently
[23:39] <jcoxon> confirmed from wb8elk email
[23:40] <Zupht0r> According to all the regs we found, 7.102 is legal in the US. Of course, the damn FCC documentation can be vague and obtuse.
[23:40] <fsphil> urg, S9 noise on 40m here
[23:40] <Zupht0r> It *is* against the ARRL plan, tho
[23:40] <jcoxon> lets just move on i suggest
[23:41] <Zupht0r> Agreed

[23:48] <Hibby> if I wasn't in the city centre I'd string up the 40m longwire or dipole and join in :/
[23:49] <jcoxon> :-)
[23:52] <Hibby> after I got my 817 back from group0
[23:53] <fsphil> added a few baluns and loops to the coax, got the noise down to S8
[23:54] <LazyLeopard> `Noise on HF here is around S7ish. is that 7.102 a dial frequency, of the actual frequency of the transmission?
[23:55] <jcoxon> dial freq
[23:55] <fsphil> got some morse code there
[23:56] <LazyLeopard> Yeah. Endless CQing...
[23:56] <LazyLeopard> The voice QRM sounds weird on USB. ;)
[23:57] <fsphil> yea
