[00:00] <scotty> cheers
[00:09] <natrium42> done
[00:10] <DoYouKnow> you guys have seen the 1337 project?
[00:10] <DoYouKnow> http://space.1337arts.com/
[00:11] <natrium42> yes
[00:16] <DoYouKnow> "FAA regulations only apply to balloons with payloads over four pounds."
[00:16] <DoYouKnow> nice :)
[00:17] <DoYouKnow> we don't have to be licensed either... but I'd assume it's unwise to fly it over the flight paths. Probably have to go a little bit out, at least
[00:20] <DoYouKnow> but anyway, looking again at there site, it's utter coolness

[00:24] <edmoore> they've all shifted east
[00:24] <edmoore> and a bit north
[00:24] <edmoore> so a 10am sunday launch lands in in watford
[00:24] <jonsowman> is it looking ok for sunday edmoore
[00:24] <jonsowman> ?
[00:24] <jonsowman> also, we have the ferret tracker working
[00:24] <edmoore> not currently
[00:25] <edmoore> take a look on sattelite view
[00:25] <jonsowman> ok
[00:25] <edmoore> 10am puts it in a residential area
[00:25] <jonsowman> is there anything to make an antenna out of in the lab?
[00:25] <edmoore> there should be loads and loads of coax floating around
[00:26] <jonsowman> and for radials?
[00:27] <edmoore> just any old wire
[00:27] <edmoore> as long as it conducts, it'll work
[00:28] <jonsowman> ok cool
[00:28] <jonsowman> will you be at the lab tomorrow by any chance?
[00:33] <scotty> hey ed, is everything cool for sunday i checked the prediction looks good
[00:43] N900evil (~Speedevil@tor/regular/SpeedEvil) joined #highaltitude.
[00:46] <scotty> i've looked and sunday looks fine to me :)
[00:58] <jonsowman> scotty: bear in mind luton apt
[01:03] <edmoore> scotty: a 10am launch currently puts us in watford, which isn't particularly good
[01:03] <edmoore> to give you an idea, we usually only launch when the wind takes it north-east from cambridge into the fairly empty fens of east anglia
[01:04] <edmoore> london suburbs are a different ball-game altogether. will have to keep eyes on the plot
[01:04] <edmoore> it could easily shift again
[01:05] <edmoore> right, I'm going to head in
[01:05] <jonsowman> edmoore and scotty: reckon its better to shove this ferret tracker in a seperate box and have it as a seperate payload?
[01:05] <scotty> right
[01:05] <scotty> seperate payload?
[01:05] <edmoore> jonsowman: have it self contained, but i'd be inclined to attach it to the main payload
[01:05] <edmoore> otherwise you can get some chaotic pendulum motion
[01:05] <jonsowman> right
[01:05] <scotty> cool :)
[01:06] <jonsowman> are you in the dept tomorrow edmoore
[01:06] <edmoore> I can be yeah
[01:06] <scotty> well i hope sunday will be good :)
[01:06] <edmoore> not too early though please :)
[01:06] <scotty> cos im well looking forward to it
[01:06] <edmoore> ultimately it's your payload so your call :)
[01:06] <edmoore> but we'll do our best to get it up
[01:06] <scotty> cheers :)
[01:06] <jonsowman> Randomskk and I will be there for some of the day tomorrow
[01:07] <jonsowman> will let you know what times edmoore
[01:07] <edmoore> iain is in there for a good chucnk too
[01:07] <edmoore> ok thanks
[01:07] <edmoore> i probably won't be down in the morning but ,may come after brunch
[01:07] <edmoore> right, see you
[01:07] <scotty> xool

[01:08] <scotty> :)
[01:08] <scotty> so jon do u think sunday will be ok, i know its shifting closer to cambridge at the moment
[01:10] <jonsowman> scotty: the problem is luton apt and getting into london suburbs
[01:10] <jonsowman> which is generally not a great idea
[01:11] <scotty> yeah..
[01:15] <scotty> well i did the predictor for 13:00 and its in sandrige..
[01:15] <scotty> that well clear of london
[01:15] <scotty> i dont see luton airport either
[01:16] <SpeedEvil> You want it so that it's going to be clear of anywhere - when you launch +-1 hour, and with the lift varying between 50 and 150% of nominal
[01:16] <SpeedEvil> At teh absolute minimum IMO
[01:16] <SpeedEvil> And moving the launch location by 1km around the site gives you an idea of the stability
[01:16] <scotty> right
[01:17] Last message repeated 1 time(s).
[01:17] <scotty> the radius on the flight predictor gives me the 1 km around
[01:18] <scotty> still doesnt hit london lol
[01:18] <scotty> maybe im wrong
[01:19] <scotty> well im up for it :)
[01:19] <scotty> gotta go, cheers guys :) have a good night

[01:28] <natrium42> haha, 10th march is nice
[01:28] <natrium42> you launch in cambridge and it lands in cambridge
[01:31] <jonsowman> yup 1200 launch gives a landing site 6 miles away
[01:31] <jonsowman> haha
[01:31] <natrium42> :)
[01:34] <jonsowman> we might do a launch weds then, we'll see
[01:36] <natrium42> badgercub?
[01:36] <natrium42> did that silabs transceiver work well?
[01:37] <jonsowman> im not sure whats going on with BC at the moment
[01:37] <jonsowman> havent spoken to ed about it
[01:56] <jonsowman> hmm wonder if we can do a weds launch
[01:56] <jonsowman> thatd be brilliant

[06:13] <natrium42> not bad, you?
[06:14] <juxta> I'm alright :)
[06:14] <juxta> will be launching again on monday
[06:14] <natrium42> coolz, what's the payload?
[06:15] <juxta> just gps and radio
[06:15] <juxta> only using a 200g balloon
[06:15] <juxta> wanting to test higher telemetry rates
[06:16] <natrium42> neat
[06:16] <juxta> I think I will wait till gets atm I'm thinking of waiting till it gets to 5km
[06:17] <juxta> then switching to 100b for 2km, back to 50b for 1km, upto 150b, etc etc
[06:17] <juxta> involves a bit of mucking around in fldigi is the only thing
[06:18] <SpeedEvil> maybe just 50,100,150,50,100,150, ...
[06:18] <natrium42> and to a safe rate at descent :D
[06:18] <SpeedEvil> just repeating
[06:18] <SpeedEvil> it'll only ~half the rate at which 50 strings normally go
[06:19] <natrium42> true
[06:19] <juxta> I'll be back to 50b for descent
[06:20] <juxta> I was thinking of interleaving with 50b chunks incase we can't decode the higher bitrates
[06:20] <juxta> I need to pop it on a CRO and make sure the timing is right

[11:19] <MikeMc68> Hi
[11:19] <Randomskk> by DL client do you mean payload xml type?
[11:19] <MikeMc68> The launch site is Churchill college grounds right ?
[11:19] <Randomskk> yes
[11:19] <MikeMc68> yes
[11:19] <Randomskk> though the launch isn't confirmed yet
[11:19] <Randomskk> it's "orion"
[11:20] <MikeMc68> Orion isnt in the DL Client list
[11:20] <Randomskk> reload dl-fldigi, it should appear
[11:20] <Randomskk> admittedly it's not in mine either

[11:26] <Randomskk> Laurenceb: looks pretty cool
[11:26] <Laurenceb> yeah power supplies need more work atm
[11:26] <Laurenceb> also I need a falcom fsa03 footprint
[11:26] Action: SpeedEvil needs a yeti footprint.
[11:29] <MikeMc68> you can get the footprint from the eagel cad library
[11:29] <MikeMc68> available from esawdust
[11:29] <Laurenceb> huh
[11:29] <MikeMc68> i have a copy
[11:29] <MikeMc68> is that what you meant ?
[11:29] <Laurenceb> yes
[11:29] <Laurenceb> pls ;P
[11:29] <Laurenceb> wheres the download?
[11:30] <MikeMc68> pm me your email i'll send it to you
[11:31] <jonsowman> morning all :)
[11:31] <MikeMc68> hi
[11:31] <MikeMc68> the predictor is now saying a landing spot near the south coast (Brighton)
[11:31] <jonsowman> for when
[11:32] <MikeMc68> ahh - weird - now it's back near Bracknell again
[11:32] <Laurenceb> done
[11:33] <MikeMc68> sent
[11:33] <MikeMc68> if you can get it to burst at 60km it will land pretty much near where it took off from ;)
[11:35] <SpeedEvil> That seems unlikely.
[11:35] <MikeMc68> :D
[11:36] <MikeMc68> theoretically - what would happen if you put 3 balloons on a payload - each with varying degrees of helium in ?
[11:36] <MikeMc68> i presume there is a point where no matter what it just won't go any higher?
[11:38] <SpeedEvil> yes
[11:39] <SpeedEvil> at some point you get to where an inflated balloon will have an internal pressure increase with diameter greater than the external pressure lapse with diameter at the point at some point
[11:39] <SpeedEvil> this means it's neutrally bouyant.
[11:39] <SpeedEvil> with no, or very little payload - this might be at 40km, say.
[11:40] <SpeedEvil> 60km is on the order of 30 times less dense than 40km, so will besically require _much_ larger balloons
[11:43] <Laurenceb> MikeMc68: interesting how the top pads are placed
[11:44] <Laurenceb> more clearance from the routing maybe
[11:44] <MikeMc68> yeah

[11:50] <SpeedEvil> hmm
[11:52] Action: Laurenceb wonders about pwming the EN pin
[11:55] <jonsowman> !ping edmoore
[11:59] <Laurenceb> I guess falcom recommend a 33uF tant on the gps, and the TI reg i was going to use has a 500us linear ramp up softstart
[11:59] <Laurenceb> - fixed
[11:59] <Laurenceb> so thats approx 200ma
[12:00] <Laurenceb> so as long as the micro isnt running any nasty hardware at the same time thats fine

[13:27] <edmoore> sunday launch looking better now with the 6Z
[13:28] <edmoore> although it traces a loop around luton airport.
[13:28] <edmoore> it really is a minefield around there

[13:49] <scotty> looks like everything weather wise looks good for sunday :) payload is no where near london :)
[13:49] <scotty> keeps moving west
[13:52] <juxta_> good news
[13:52] <juxta_> was anything organised re tracking?
[13:52] <juxta_> edmoore: the issue was that I was pasting the telem in including the $$ preamble, which wasnt being stripped out
[13:52] <scotty> yeah ed and random sky said they could add another box i tink
[13:53] <scotty> well they said they had a box that they add with my payload for live tracking
[13:53] <scotty> set up the http://spacenear.us/tracker/
[13:53] <scotty> too..think its all good.
[13:54] <juxta_> excellent :)
[13:55] <scotty> misses lutons flight path
[13:55] <juxta_> heh, the car you can see on the tracker is one of our chase cars for Monday, looks like he was doing some testing
[13:55] <scotty> oh cool.
[13:55] <scotty> i think mike is coming tommorw, to help track with his car

[14:36] <jcoxon> jonsowman, hows the crazy tracker construction going?
[14:37] <jonsowman> we are ferreting (haha) around the lab finding bits and pieces to put together
[14:37] <jonsowman> atm a second arduino protoboard or similar so we can make a second tracker

[14:37] <jcoxon> jonsowman, do you need code?
[14:38] <jcoxon> you can use tinygps lib to parse the nmea on the arduino
[14:38] <jonsowman> we're ok on code at the moment, it all works
[14:38] <jcoxon> and got easy rtty code
[14:38] <jonsowman> we just need to make it do checksums
[14:38] <jcoxon> calculations is on the wiki
[14:38] <jonsowman> lovely cheers
[14:38] <jonsowman> we just really need an arduino protoboard at the mo

[14:39] <jonsowman> cannot find one in the lab and ed isn't picking up his phone
[14:39] <jcoxon> there is something fun about rapid payload construction
[14:40] <jonsowman> yep
[14:40] <jonsowman> but also frustrating when you cant find the required bits
[14:40] <jonsowman> haha
[14:40] <jcoxon> we should perhaps organise a weekend - launch on sunday, construct saturday
[14:40] <jcoxon> with junk brought along by everyone
[14:40] <jcoxon> see if we can pull off any crazy prototypes/ideas
[14:41] <jonsowman> haha that'd be great fun
[14:42] <jcoxon> scrapheap HAB challenge
[14:43] <jcoxon> something perhaps for the summer, post exams
[14:44] <jonsowman> sounds like a good plan
[14:51] <jonsowman> well well no protoboard
[14:51] <jonsowman> stripboard it is.
[14:51] <jcoxon> not got any atmega168s lying around
[14:52] <jcoxon> to make your own custom board?
[14:52] <russss> so, I've had no success getting hold of anyone WRT running amateur radio courses at the hackspace :/
[14:52] <russss> does anyone know any instructors in the London-ish area?
[14:52] <jonsowman> hmm we were thinking that but we then have to xtals and caps etc - easier if we can just use the arduino i think
[14:53] <jonsowman> <randomskk> also there aren't any lying around
[14:53] <russss> Bromley and District ARS look active but their email bounces :/
[14:54] <jcoxon> i did mine at BDARS
[14:54] <jcoxon> jonsowman, pah use internal osc
[14:54] <russss> I really want to dispel the stereotype that radio amateurs are old and have no grasp of modern technology but this isn't helping.
[14:54] <jcoxon> russss, ummm i have some email address
[14:54] <russss> cool
[14:54] <Randomskk> russss: haha because they are
[14:54] <Randomskk> jcoxon: we still don't have any atmegas lying around
[14:55] <Randomskk> shedloads of pics though
[14:55] <jcoxon> Randomskk, fair enough
[14:55] <russss> I should get some ATmegas for the hackspace to join our collection of ATTinys
[14:55] <Randomskk> and all I have at college are smt atmegas
[14:56] <jcoxon> russss, i should switch my beacon from an atmega168 to a attiny

[15:02] <jcoxon> is
[15:02] <jcoxon> ?
[15:02] <jcoxon> its transparent with copper cable, continous rather then gaps down the middle
[15:05] <SpeedEvil> you mean there are two conductors next to each other like a 8
[15:05] <SpeedEvil> with a lead in the middle of each o
[15:06] <jcoxon> yeah but there is a gap inbetween of about 40mm
[15:07] <SpeedEvil> that sounds like 300 ohm
[15:07] <SpeedEvil> I forget the dimensions though
[15:07] <SpeedEvil> there are calculators out there

[15:33] <scotty> yeah same :)
[15:33] <scotty> looking forward to it too!
[15:33] <edmoore> emphasis on hitting the launch window though as it's not a great day.
[15:34] <scotty> i have got everything that was on the check list
[15:34] <edmoore> cool
[15:34] <scotty> well, when is the best time for launch....
[15:34] <scotty> i think 10:00
[15:34] <scotty> am
[15:34] <scotty> puts it in woodrow...
[15:34] <edmoore> scotty - can you take a picture of the bottom of your box?
[15:35] <scotty> yeah i'll do that now
[15:36] <jcoxon> edmoore, any experience with ladder line?
[15:37] <edmoore> never used it I'm afriad

[15:40] <edmoore> cool
[15:41] <edmoore> what time can you get here tomorrow?
[15:41] <scotty> Any time! i need you to tell me whens best
[15:41] <edmoore> early as poss I guess
[15:41] <scotty> 10:00 am launch looks good
[15:41] <edmoore> yeah
[15:41] <scotty> well i can get there for 9:30
[15:41] <edmoore> so assuming it works, if you get here at 8.30 that should be loads of time
[15:41] <scotty> (its 2 hour dirve from kent)
[15:42] <edmoore> 9.30 is too late
[15:42] <scotty> ok ok :) i can get there at 8:30
[15:42] <scotty> will you be there?
[15:42] <scotty> or your two collegues?
[15:42] <edmoore> just incase something doesn't quite work, which often happens
[15:42] <scotty> yeah
[15:42] <edmoore> i will probably be there for the beginning
[15:42] <scotty> cool...:)
[15:42] <edmoore> i need to get the helium and so on
[15:43] <scotty> so when i get there i will give u a bell at 8:30. will you be in the bar
[15:43] <scotty> (if it opens that early lol)
[15:43] <edmoore> yep
[15:43] <edmoore> it should be open for breakfast
[15:43] <scotty> cool!
[15:43] <edmoore> a beer might be pushing it though
[15:44] <scotty> well give me a bell tonight if anything changes drasticly. but the weather should be fine. see you tommorw at churchill college at 8:30 :)
[15:44] <scotty> im bringing all on the checkist + balloon, payload and parachute.
[15:45] <scotty> (laptop internet etc)
[15:45] <edmoore> cool
[15:45] <edmoore> the more you can heave ready on arrival (eg parachute attached to payload so it can just be tied to the balloon) the better
[15:46] <edmoore> leave a good meter or so between the payload and the parachute, so the chute is clear of the forebody wake
[15:49] <scotty> im not sure how to do the parachute to the payload attachment ( made a loop in the spin hold of the parachute) i have a ring on the payload for the main cord to be attached. and i have it all marked out..should be 5 mins set up. Just want to make sure i have the best cord knot :)
[15:49] <scotty> i have all the cord measured out. 15 meters for parachute then extra 5 for balloon. 20 meters overall.
[15:50] <edmoore> ok excellent
[15:50] <edmoore> well we can sort that out tomorrow then
[15:51] <scotty> cool:) see you tommorw at 8:30. Thanks

[20:48] <jonsowman> thanks a lot :)
[20:48] <natrium42> dunno what happened
[20:48] <natrium42> i switched the server to UTC, maybe that's why
[20:49] <natrium42> should be able to set local time in the config, eh...
[20:50] <jonsowman> in which config?
[20:50] <natrium42> there's a config.php with all mission settings
[20:50] <natrium42> eventually there will be a backend where you login and set it up
[20:50] <jonsowman> ah right i see
[20:51] <natrium42> btw, going to work on flight prediction today
[20:51] <natrium42> maybe it will be ready for flight tomorrow :)
[20:52] <jonsowman> that'd be brilliant
[20:52] <jonsowman> i think the weather is looking alright for tomorrow, not fantastic but probably launchable
[20:52] <natrium42> good
[21:08] <rjharrison> bad day
[21:08] <rjharrison> :-(
[21:09] <Lunar_Lander> ohhhhh
[21:09] <rjharrison> Teenager from wife previous marrage decided to steal 3K worth of goods from house
[21:10] <rjharrison> Abd sell them to go away for the weekend
[21:10] <rjharrison> humm
[21:10] <SpeedEvil> :/
[21:11] <SpeedEvil> I hate that happening as it may mean that it's not covered on insurance. Even over all of the other shit.
[21:12] <SpeedEvil> Which is also no fun. Wish there was an easy solution - but...

[21:21] <rjharrison> oooh launch tomorrow?
[21:21] <jonsowman> yes, weather permitting
[21:21] <Laurenceb> rjharrison: what happened?
[21:21] <jonsowman> its touch and go weather-wise at the moment
[21:22] <rjharrison> If launch tomorrow and lands henly I have local resource for recovery
[21:23] <rjharrison> Laurenceb well basicaly wife child from previous marrge who has live with use week on week off for the last 14 years decided to steal 3k of goods and sell them to fund his lifestyle
[21:23] <Laurenceb> ouch
[21:23] <Laurenceb> good luck sorting it out
[21:24] <rjharrison> in the last 6 months has given up alevels at college moved in with bad crown and now wants to live on benifits and cant do it till hes kicked out of home
[21:24] <rjharrison> So he trashed his dads house by having a facebook party
[21:24] <Laurenceb> :(
[21:25] <rjharrison> and then stoke 2 laptops and my camera fromthe house a long with the kids Ds's
[21:25] <rjharrison> stole
[21:25] <rjharrison> 3K of goods
[21:25] <rjharrison> :(
[21:25] <jonsowman> that's awful

[21:26] <jonsowman> best of luck sorting it out
[21:26] <rjharrison> Yep
[21:26] <rjharrison> Esp when my kids are 9 6 and 2

[21:42] <SpeedEvil> jonsowman: yes
[21:43] <SpeedEvil> jonsowman: along with an indication that it's not a valid lock
[21:43] <SpeedEvil> jonsowman: simply outputting the GPS time works for example
[21:43] <Randomskk> jonsowman: e.g. perhaps '0 satellites in view'
[21:43] <Randomskk> or that
[21:43] <jonsowman> ok, will do
[21:43] <jcoxon> yeah put out the last position, i swap all my commas for forward slashes
[21:43] <SpeedEvil> Nobody might have heard the last position of the GPS for example.
[21:43] <jcoxon> so that it doesn't get uploaded to the server
[21:44] <jonsowman> clever
[21:51] <SpeedEvil> Is there a reason not to just output last GPS time, and position?
[21:54] <jcoxon> not really

[22:09] <Randomskk> btw the tracker doesn't accept lat,lon 0,0
[22:09] <juxta_> morning
[22:09] <Randomskk> heya
[22:10] <juxta_> that's by design, isnt it Randomskk?
[22:10] <SpeedEvil> Randomskk: planning on launching from a boat off africa?
[22:10] <Randomskk> so actually we could just have it transmit that when there's no lock, hmm
[22:10] <Randomskk> SpeedEvil: ha it could potentially be an issue one day
[22:10] <Randomskk> juxta_: yea
[22:10] <SpeedEvil> :)
[22:10] <Randomskk> but just this payload currently transmits a valid packet with 0,0 when there's no lock
[22:10] <Randomskk> though i guess last known position is still better
[22:10] <SpeedEvil> when there is no lock - that doesn't mean that your last broadcast of the position before lock was picked up
[22:11] <Randomskk> it is being a bit shit getting a lock
[22:11] <juxta_> yeah I think last known is better
[22:11] <Randomskk> SpeedEvil: yea
[22:11] <Randomskk> also need to implement the checksum
[22:11] <jcoxon> Randomskk, the chances that its actually 0.00000 0.000000 will be so small
[22:11] <Randomskk> though it seems the tracker doesn't actually care
[22:11] <jcoxon> it'll accept 0.01 0.0000
[22:11] <jcoxon> for example
[22:11] <Randomskk> jcoxon: fine I will do a launch at 0,0 just for you :p
[22:11] <juxta_> Randomskk: use the CRC16 checksum, XOR is a bit weak
[22:11] <jcoxon> Randomskk, with GPS drift :-p
[22:11] <jcoxon> good luck
[22:12] <Randomskk> juxta_: this thing is flying tomorrow, so we want the simplest thing possible
[22:12] <Randomskk> if crc16 is still simple to calculate over the string to be transmitted then we can do that
[22:12] <SpeedEvil> yeah - 0,0 or one launch isn't an issue
[22:12] <juxta_> there's an avr library for crc16
[22:12] <SpeedEvil> for
[22:14] <juxta_> Randomskk: http://pastebin.com/jtN2H8cp
[22:15] <Randomskk> oh sweet
[22:15] <Randomskk> okay
[22:15] <Randomskk> will do that
[22:17] <juxta_> Randomskk: here's the xor sum:
[22:17] <juxta_> http://pastebin.com/rzLtcjXr
[22:17] <Randomskk> does the tracker need to be told it's doing crc16?
[22:17] <juxta_> Randomskk: nah it will pick it up by the checksum length
[22:18] <Randomskk> okay cool
[22:18] <juxta_> hmm, that break on the asterisk is a bit redundant in the xor sum method, oh well
[22:19] <juxta_> Randomskk: is this for scotty's launch?
[22:19] <Randomskk> yea
[22:19] <Randomskk> our box to be stuck on the side
[22:19] <juxta_> ah cool :)
[22:19] <Randomskk> em406a gps, ntx2 radio, arduino
[22:19] <Randomskk> plus four lithium AAs and a 434 vertical+radial groundplane antenna
[22:20] <Randomskk> tiny tracker
[22:20] <Randomskk> spent this afternoon making it at the cusf lab
[22:20] <juxta_> :)
[22:20] <juxta_> thats basically what my payload is for monday
[22:20] <Randomskk> hehe yup
[22:20] <Randomskk> it's good fun and pretty straightforward to make
[22:20] <juxta_> I have a backup cw beacon too, but I'm debating weather to fly it
[22:20] <Randomskk> otoh this GPS cuts out above 24km
[22:21] <juxta_> yeah thats a bit of a pain
[22:21] <juxta_> I used the lassen
[22:21] <fsphil> is there a camera in tomororws payload?
[22:21] <fsphil> tomorrows
[22:21] <juxta_> I made up a shield for the arduino with the ntx etc onboard
[22:21] <Randomskk> but that's significantly better than the current on-board system that scott's flying, e.g. a mobile phone
[22:21] <Randomskk> fsphil: yes, and video
[22:21] <Randomskk> juxta_: yup same
[22:21] <fsphil> sweet
[22:21] <Randomskk> well ours is a bit of stripboard
[22:21] <Randomskk> but still
[22:21] <juxta_> whatever works ;)
[22:21] <fsphil> I've give the yagi a go tomorrow, but as I understand it by the time it's above my horizon the GPS won't be working
[22:22] <Randomskk> potentially
[22:22] <juxta_> how'd you get around the header spacing issue Randomskk?
[22:22] <Randomskk> it may not cut out until 27km or more
[22:22] <juxta_> fsphil: where are you?
[22:22] <Randomskk> juxta_: we just didn't need to use anything D8 onwards
[22:22] <juxta_> oh righto
[22:23] <juxta_> hmm
[22:23] <fsphil> juxta, middle of n.ireland: 54.6°N, 6.7°W
[22:23] <juxta_> my battery has the red X on it, I think I'll be forced to get out of bed soon
[22:23] <fsphil> just about line of sight, depending on which way the balloon goes
[22:23] <juxta_> ah alright - will be interesting to see when you hear it :)
[22:24] <juxta_> Randomskk: re the gps lock etc
[22:24] <jonsowman> we're running it on AA alkalines at the moment and it might be undervolting the GPS a bit
[22:25] <jonsowman> the time is correct but lat/long is 0/0
[22:25] <juxta_> I think jcoxon said he likes to change the telemetry format if it loses lock, to something like ORION/XX/lat/long/x/x
[22:25] <Randomskk> yea
[22:25] <Randomskk> we may do that
[22:25] <juxta_> or you could transmit the number of sats
[22:25] <juxta_> thats what I did, it's useful for biting your nails and hoping it gains lock
[22:26] <jonsowman> number of sats is included in the string anyway
[22:26] <Randomskk> yea, thinking of doing that - at least then it'l show up on the raw data page
[22:26] <Randomskk> rather than having to get people to paste it into irc etc
[22:29] <juxta_> righto, time to get up
[22:30] <juxta_> what time is the launch Randomskk?
[22:30] <Randomskk> 10AM
[22:30] <Randomskk> UTC
[22:30] <juxta_> ok that's doable for me
[22:30] <juxta_> I'll try to be online
[22:30] <juxta_> best of luck :)

[22:43] <Laurenceb> neat

[22:47] <Randomskk> fair*
[22:48] <natrium42> shall i take out the (0,0) check?
[22:48] <natrium42> it was there because of lauches without error checking >:|
[22:49] <Randomskk> nah
[22:49] <Randomskk> it's good
[22:49] <Randomskk> ours currently still transmits 0,0 occasionally
[22:49] <Randomskk> (won't by launch hopefully)
[22:49] <Randomskk> checksum was the first thing we needed to change in the code
[22:49] <Randomskk> second is what it does when it loses gps lock
[22:49] <Randomskk> and third is getting it to tell the gps to reset

[23:25] <Randomskk> it is
[23:25] <Randomskk> the crc16 is valid
[23:25] <jonsowman> :)
[23:25] <jonsowman> awesome
[23:26] <Randomskk> still lat/lon 0
[23:26] <Randomskk> once it gets lock it should show up on tracker
[23:26] <jonsowman> yup
[23:26] <jonsowman> give it a couple of mins
[23:26] <jonsowman> can i have a copy of the new code
[23:26] <Randomskk> you do
[23:26] <jonsowman> attach the pde if you can

[23:26] <Randomskk> or scp it
[23:26] <jonsowman> hmm yes its just screwy formatting
[23:26] <jonsowman> cheers
[23:27] <Randomskk> it's in your home dir on my pc

[23:28] <jonsowman> gps locked.
[23:28] <jonsowman> Randomskk:
[23:29] <jonsowman> and we're on the tracker
[23:29] <jonsowman> yay
[23:29] <Randomskk> ! sweet
[23:29] <Randomskk> how do we communicate not having lock
[23:29] <Randomskk> since satellites in view may be non-zero
[23:29] <Randomskk> otherwise we can't differentiate between that and the position just not changing
[23:29] <Randomskk> could have it say -1 satellites in view when no lock
[23:30] <SpeedEvil> there is a position valid field
[23:30] <Randomskk> but it might be more useful to know how many satellites were in view
[23:30] <jonsowman> http://aprs.gids.nl/nmea/#gga
[23:30] <Randomskk> SpeedEvil: not on our xml
[23:30] <Randomskk> jonsowman: that's not the issue, I've got it parsing it
[23:30] <Randomskk> but how do we alter our radio output
[23:30] <jonsowman> , -> /
[23:30] <Randomskk> it's currently just time, lat, lon, alt, #sats
[23:30] <jonsowman> maybe?
[23:30] <Randomskk> jonsowman: but then it won't get uploaded to the tracker

[23:30] <SpeedEvil> right
[23:31] <SpeedEvil> negate teh number of sats if no lock
[23:31] <SpeedEvil> ?
[23:31] <Randomskk> SpeedEvil: oh good idea
[23:31] <Randomskk> cheers
[23:31] <jonsowman> you alright to do that Randomskk? might go to bed lol
[23:31] <jonsowman> im sure you wont have problems testing it in no-lock condition in your room
[23:31] <Randomskk> yea, though it might need testing
[23:31] <Randomskk> it's all coded
[23:31] <jonsowman> haha
[23:32] <jonsowman> ill bring it down
[23:33] <jonsowman> is it still working?
[23:33] <Randomskk> yea
[23:33] <jonsowman> its on batts
[23:33] <Randomskk> nice
[23:33] <Randomskk> hmm its position is not particularly accurate
[23:33] <Randomskk> but still, close enough
[23:33] <Randomskk> pretty good really
[23:34] <LazyLeopard> Seems to be exploring Cranmer Road at the moment. ;)
[23:34] Action: SpeedEvil wonders what Magellan would have said at the pronouncement that a few meters is not particularly accurate :)
[23:35] RocketBoy|Away (~steve@217.47.75.8) left irc: Quit: Leaving
[23:36] <Randomskk> SpeedEvil: heh
[23:36] <jonsowman> Randomskk: locked.
[23:36] <Randomskk> rolling in his grave etc
[23:36] <Randomskk> jonsowman: cool yup
[23:37] <Randomskk> need to get the current track on spacenearus cleared I guess, and ideally the view.php raw data
[23:38] <Randomskk> okay it now keeps sending last known position but negates sats in lock
[23:38] <Randomskk> when loses gps
[23:39] scotty (~sj86@94-195-51-124.zone9.bethere.co.uk) left irc:
[23:43] <jonsowman> Randomskk: could i have the new code plox
[23:43] <Randomskk> copied
[23:43] <Randomskk> resetting it looks a bit complex
[23:43] <Randomskk> don't think I'll bother for today
[23:43] <Randomskk> maybe for wednesday if we recover
[23:43] <jonsowman> ok
[23:44] <MikeMc68> is this for tomorrow mornings launch ?
[23:44] <Randomskk> yup
[23:44] <MikeMc68> is it going to work ?
[23:44] <Randomskk> MikeMc68: did you find out about parking?
[23:44] <Randomskk> MikeMc68: it works so far
[23:44] <MikeMc68> nope
[23:44] <Randomskk> but the gps has the altitude limit
[23:44] <MikeMc68> cool cos i'm driving all the way from kent to help track this thing :D
[23:44] <Randomskk> and it may or may not regain lock
[23:44] <Randomskk> hmm
[23:44] <Randomskk> scott is at the uni of kent
[23:45] <MikeMc68> i know
[23:45] <Randomskk> both driving seperately?
[23:45] <MikeMc68> yep
[23:45] <Randomskk> fair enough
[23:45] <Randomskk> at any rate it is working so far
[23:45] <Randomskk> spent today making the antenna, arduino shield etc
[23:45] <Randomskk> antenna looks fantastic
[23:45] <MikeMc68> no idea where he is driving from or at what time
[23:45] <Randomskk> it's some colourful drinking straws taped to a bit of copper clad board
[23:46] <terry> juxta_: hi, wasn't then, but am now.
[23:46] <juxta_> morning terry
[23:46] <terry> gday
[23:47] <juxta_> are you in melb or syd? I forget
[23:47] <juxta_> syd I think?
[23:47] <terry> sydney
[23:47] <MikeMc68> Does the tracker plot the cars - and if so how ?
[23:47] <juxta_> bummer. if were were in melbourne you might *just* have been able to pickup my balloon on monday if you had a radio
[23:47] <juxta_> MikeMc68: if they announce their positions, yes
[23:47] <Randomskk> MikeMc68: I believe it can if fldigi is provided with a agps device
[23:47] <Randomskk> a gps device*
[23:48] <Randomskk> if you have a serial gps device then fldigi can read it
[23:48] <terry> juxta_: that would have been fun.
[23:48] <juxta_> Randomskk: fldigi doesnt do it at the moment, the code isnt in place
[23:48] <Randomskk> oh, really?
[23:48] <MikeMc68> a usb gps mouse >
[23:48] <Randomskk> dang
[23:48] <Randomskk> it does have a gps input but okay
[23:48] <juxta_> it's just a gui frontend at the moment
[23:48] <Randomskk> ah okay
[23:48] <MikeMc68> so it doesn't work ?
[23:48] <juxta_> (according to jcoxon as of a few days ago at least) ;p
[23:48] <juxta_> well, it can do MikeMc68
[23:48] <juxta_> you just write a little ap
[23:49] <juxta_> I wrote a java one for our launch, it just reads a GPS and posts it to the tracker
[23:49] <MikeMc68> i don't have time for that now
[23:50] <MikeMc68> if it doesn't work 'out of the box' then i won't bother
[23:50] <juxta_> I can send you mine if you like
[23:52] <MikeMc68> cheers
