[00:00] <RocketBoy> but I don't think thats necissarily the way to go
[00:01] <RocketBoy> its worth a thought - perhaps make a small one
[00:02] <jcoxon> yeah, its an interesting idea
[00:02] <Laurenceb> yes, you can go a long way with ballast
[00:02] <Laurenceb> if its bone well and you dont get sucked into a weather system
[00:04] <RocketBoy> I was thinking of giving it a go with heat sealed metalized nylon/polyester?
[00:05] <Laurenceb> sounds good
[00:05] <RocketBoy> maybe even go for the pumpkin idea

[00:18] <jcoxon> aaarrrgghhh
[00:18] <jcoxon> something must be working
[00:18] <jcoxon> if i put it direct into AT mode the Tx and Rx light up if i send a command
[00:18] <jcoxon> if its in python script mode only tx lights up
[00:19] <jcoxon> which is right if its trying to compile the scripts i uploaded yesterday
[00:19] <jcoxon> (which it will fail on as they use the GPS lib which it doesn't have
[00:21] <jcoxon> oh well
[00:21] <jcoxon> best i sleep on it

[15:44] <jcoxon> hmmmmm i think i've worked out whats wrong
[15:44] <jcoxon> my normal module runs at a measured 2.7v
[15:44] <jcoxon> however the new broken one is doing 2.61v
[15:45] <natrium42> eh?
[15:46] <natrium42> the new gm862 uses less power, perhaps that's why
[15:46] <jcoxon> this is the voltage it gives out down the lines
[15:46] <jcoxon> hmmmmm
[15:47] <natrium42> yeah, i realize that
[15:47] <natrium42> just saying that they changed things
[15:47] <natrium42> did you order yours from sparkfun?
[15:48] <jcoxon> natrium42, no, a place in the UK
[15:48] <jcoxon> i've emailed them
[15:48] <jcoxon> the thing is that the module did work originally
[15:48] <jcoxon> for about 10mins
[15:48] <jcoxon> but since i've come back to it
[15:48] <natrium42> alright, too bad about that problem
[15:48] <natrium42> seems like you are having bad luck with those modules :S

[15:50] <jcoxon> natrium42, seems so :(
[15:53] <natrium42> guh, globalstar reply --> http://rafb.net/p/qqXd4F49.html
[15:54] <natrium42> iridium is superior, but their phones are $$$
[15:54] <jcoxon> right
[15:55] <jcoxon> i should of just go the damn GM862-GPS and turned the GPS off
[15:55] <jcoxon> got*
[15:56] <natrium42> anyway, i think globalstar could be fine since service interruptions don't matter much for data transfers (but they do for phone calls)
[15:56] <jcoxon> hmmmm there is a system that CNES use
[15:56] <jcoxon> let me do some googling
[15:56] Action: natrium42 will research more
[15:56] <natrium42> inmarsat?
[15:57] <natrium42> can't you return your gm862 module and ask them for the gps version
[15:57] <natrium42> since it's broken anyway...
[15:58] <jcoxon> well i've emailed them
[15:58] <jcoxon> we shall see
[15:58] <jcoxon> the thing is that it did work
[15:58] <jcoxon> and i managed to upload a script
[16:00] <natrium42> you didn't use the brick() function, did you? :P
[16:00] <jcoxon> damn it
[16:01] <jcoxon> thats what i have in teh first function
[16:01] <natrium42> lol
[16:01] <jcoxon> just before import main
[16:01] <jcoxon> :-D
[16:01] <jcoxon> ARGOS is the CNES sat tracker
[16:01] <jcoxon> but it only will do CNES stuff, its basically 2 polar orbiting sat relay station to france

[18:29] <Laurenceb> hi all
[18:36] <akawaka> morning
[18:40] <Laurenceb> hehe
[18:40] <Laurenceb> arg horrible day
[18:40] <Laurenceb> fried my radio
[18:40] <Laurenceb> I've built a new one but it has the same problem
[18:41] <Laurenceb> it must be software
[18:43] <Laurenceb> the first byte and a half is corrupted
[18:43] <Laurenceb> it doesnt make sense
[18:45] <Laurenceb> if you dont hybernate the chip it doesnt happen
[18:45] phatmonkey (n=ben@81.2.121.150) joined #highaltitude.
[18:54] <Laurenceb> still, it explains RocketBoys problems getting it to work
[18:54] <Laurenceb> I'll ask on #avr, but I dont expect an answer
[18:56] <Laurenceb> it probably very subtle, maybe a GCC bug, or a hardware design flaw
[18:59] <Laurenceb> actually I could dump some variables in a buffer and printf it out later, that might show whats happening better
[19:03] <Laurenceb> I know the bytes get into the chip ok, and anre retrieved from the buffer ok, and that the pwm works, so its a matter f investigating the char_send function

[19:50] <mc-> Laurenceb, a thought on your radio, maybe the first few bytes are corrupted because the receiver needs to adjust the AGC?
[19:50] <mc-> or the rxer has a data slicer, which needs to adjust its level
