[00:52] <edmoore> gcc
[00:52] <Laurenceb> then olmex jtag ?
[00:52] <Laurenceb> *olimex
[00:54] <edmoore> we use crossworks
[00:54] <Laurenceb> jtag cable?

[17:24] <gordonjcp> edmoore_: wtf?
[17:24] <edmoore_> teddynauts!
[17:25] <edmoore_> so the local school's 10 and 11 year olds designed space suits for teddies
[17:25] <gordonjcp> hahaha
[17:25] <edmoore_> we rigged them up with temperature sensors to see whose teddy performed best
[17:25] <gordonjcp> that's *brilliant*
[17:25] <gordonjcp> and then flew the teddies, I see
[17:25] <gordonjcp> how did they do?
[17:25] <edmoore_> just getting the temp data off now
[17:26] <edmoore_> but there was a reasonable spread so clearly they were doing something
[17:26] <gordonjcp> how many did you fly?
[17:26] <edmoore_> 4
[17:26] <edmoore_> 2 on each side
[17:26] <gordonjcp> cool
[17:26] <edmoore_> plus some other experimenty bits and bobs, and souvenir lego astronauts
[17:27] <Ei5GTB> LOLOL
[17:27] <Ei5GTB> today?
[17:27] <edmoore_> yep
[17:27] <gordonjcp> edmoore_: total weight?
[17:27] <edmoore_> just got back
[17:27] <Ei5GTB> nice
[17:27] <edmoore_> 2kg
[17:27] <gordonjcp> edmoore_: good day for it
[17:27] <edmoore_> 1.5kg balloon
[17:27] <edmoore_> 6m/s ascent rate
[17:27] <gordonjcp> bloody cold here in Glasgow, nice thick air
[17:27] <edmoore_> 30085m
[17:27] <Ei5GTB> NICE
[17:27] <Ei5GTB> what freqs were you guys on?
[17:28] <edmoore_> 434.650
[17:28] <Ei5GTB> nice, i must listen out next flight..

[18:56] <edmoore_> wanna see a photo?
[18:56] <jcoxon> seen it
[18:56] <jcoxon> :-p
[18:56] <jcoxon> looks very cool
[18:57] <jcoxon> i was wondering if you had done that and thought to myself to suggest it if not
[18:57] <jcoxon> then i thought lego but you guys thought of that as well
[18:57] <jcoxon> :-p
[18:57] <jcoxon> haha
[18:57] <jcoxon> good launch today
[18:57] <jcoxon> so cool that you saw it land
[18:58] <edmoore_> yeah!
[18:58] <edmoore_> it looks so cool
[18:58] <jcoxon> parachute deployed?
[18:58] <edmoore_> beautifully
[18:58] <edmoore_> the 5' one from aerocon
[18:59] <edmoore_> a properly constructed one - looks much better than the crappy sheets we always use
[18:59] <edmoore_> and it was about 8m above the payload so the whole thing was very very stable
[18:59] <jcoxon> :-D
[18:59] <jcoxon> oh thats cool
[18:59] <jcoxon> was a little challenge to track today
[18:59] <edmoore_> just translated silently over the sky above us
[18:59] <jcoxon> required some reconfiguring
[19:00] <edmoore_> yeah thanks for that - sorry we forgot to tell you
[19:00] <jcoxon> hehe its okay
[19:01] <jcoxon> http://www.pegasushabproject.org.uk/wiki/doku.php/data:nova9
[19:02] <jcoxon> reckon you made 30km?
[19:03] <edmoore_> 30085m
[19:03] <jcoxon> oh nice
[19:03] <edmoore_> also, look how warm the payload case is

[19:14] <natrium> lon = 28739.8 and lon = 954

[19:34] <natrium> edmoore, next time add a beacon to each teddynaut
[19:34] <natrium> and release them all via small parachutes
[19:35] <edmoore> :)
[19:35] <edmoore> pricey, perhaps
[19:35] <edmoore> natrium: we saw it come down!
[19:35] <edmoore> was so cool!
[19:35] <edmoore> the tracking software rocks now
[19:35] <natrium> niice
[19:35] <edmoore> it told us pricesly the place in the road to park that lay under the path, and sure enough a few minutes later it went right overhead
[19:36] <jcoxon> thats amazing
[19:36] <jcoxon> so the tracking code also predicts now
[19:36] <jcoxon> both are intergrated?
[19:36] <natrium> does it calculate descent rate also?
[19:39] <edmoore> yes
[19:39] <jcoxon> cool
[19:39] <edmoore> it dynamically updates drag model for payload based on actual telem
[19:39] <jcoxon> right i'm off
[19:39] <jcoxon> cya all
[19:39] <edmoore> and the prediction and dynamic updates are now fully integrated

[22:48] <jcoxon> natrium, no pics from me
[22:48] <jcoxon> wasn't there!
[22:49] <natrium> yes, but you have a direct line to cusf :)
[22:49] <fergusnoble> they were LM75
[22:50] <fergusnoble> have any gone up on our website yet?
[22:51] <Laurenceb> on the board?
[22:51] <fergusnoble> no, just soldered wires directly to the pins and blobbed them in epoxy
[22:52] <fergusnoble> were all daisy chained onto the i2c port on the board
[22:53] <Laurenceb> ah cool
[22:53] <Laurenceb> I tried to use something similar on the aerosol sampler
[22:54] <Laurenceb> but it just kept failing, we couldnt work out why
[22:54] <fergusnoble> yeah, its a pita
[22:54] <Laurenceb> after 4 attempts we went with a thermistor
[22:54] <fergusnoble> had to stay up all night soldering and coding just to get that working
[22:54] <Laurenceb> we didnt use the LM75... I cant remeber what it was now
[22:55] <Laurenceb> :P
[22:55] <fergusnoble> yo wouldnt think a temperature sensor could cause so much trouble :)
[22:55] <Laurenceb> it was something insanely small as we needed to know the airflow temperature in a 2mm tube
[22:55] <Laurenceb> I'm still trying to get this stupid eeprom working

[22:57] <Laurenceb> but the data coming out is still completely corrupted
[22:57] <fergusnoble> ok, just processing the photos from one camera
[22:57] <Laurenceb> there seem to be areas of SRAM getting overwritten on the actual AVR
[22:58] <fergusnoble> too tired to upload them properly so if you promise to go easy on me bandwidth wise i'll just host them locally

[23:04] <Laurenceb> which camera?
[23:05] <Laurenceb> lots of the launch crew seem to be covered in mud
[23:05] <fergusnoble> yeah, it was pretty muddy
[23:06] <fergusnoble> i think thats the premier with a polaroid filter, will have to check with iain
[23:06] <fergusnoble> also flew the powershot with a UV filter
[23:08] <Laurenceb> interesting
[23:08] <Laurenceb> premier onto gpio?
[23:08] <fergusnoble> or maybe they were both premiers, it all got changed around just before launch as we ran out of helium and had to didtch some weight
[23:08] <fergusnoble> yeah
[23:09] <fergusnoble> so we only flew 2 instead of the three planned cameras
[23:09] <fergusnoble> we needed a really high ascent rate so we emptied a whole cylinder into a 1.5kg
[23:10] <fergusnoble> im really surprised it made to to 30k
[23:10] <fergusnoble> looked ready to urst on the ground
[23:11] <fergusnoble> ok, i need to sleep
