[13:27] <edwardmoore> hi jcoxon
[13:28] <jcoxon> hey edwardmoore
[13:28] <edwardmoore> all well?
[13:28] <jcoxon> yeah
[13:28] <jcoxon> been doing my dissertation
[13:28] <jcoxon> nearly there
[13:28] <jcoxon> and yourself?
[13:28] <edwardmoore> fun for all the family
[13:28] <edwardmoore> just ticking along with work
[13:28] <edwardmoore> nothing to write home about
[13:28] <jcoxon> cool cool
[13:28] <jcoxon> drop tests on sat?
[13:29] <jcoxon> your free?
[13:29] <jcoxon> you*
[13:29] <edwardmoore> should be- where from?
[13:29] <jcoxon> time or place?
[13:29] <jcoxon> place - i'm not sure
[13:29] <edwardmoore> your call on both
[13:29] <edwardmoore> tho a not too early start would be nice
[13:29] <jcoxon> guess we don't actually need permission to do it
[13:29] <jcoxon> oh i was thinking after lunhc
[13:29] <jcoxon> lunch*
[13:30] <edwardmoore> i would suspect it might attract a little too much attention at churchill
[13:30] <jcoxon> thats what i was thinking
[13:31] <jcoxon> perhaps EARS
[13:31] <edwardmoore> yeah
[13:32] <jcoxon> i'll start putting together the payload this evening
[13:33] <edwardmoore> what is the jetstream like?
[13:35] <jcoxon> why the jetstream?
[13:35] <edwardmoore> oh don't be so naive :p
[13:36] <jcoxon> we ain't got no permission
[13:36] <jcoxon> but i'll check anyway
[13:36] <edwardmoore> if the skies are clear...
[13:36] <jcoxon> mean
[13:36] <jcoxon> very very mean
[13:37] <edwardmoore> ?
[13:37] <jcoxon> 100knots at 300mb
[13:37] <edwardmoore> lol
[13:37] <edwardmoore> ok
[13:37] <edwardmoore> sod that
[13:37] <jcoxon> it'll be quite windy on the ground
[13:38] <edwardmoore> hmmm
[13:38] <jcoxon> 22mph according to bbc
[13:38] <edwardmoore> that's a lot
[13:38] <jcoxon> grr only 6mph on friday
[13:39] <edwardmoore> life's a shitter isn't it
[13:39] <edwardmoore> hrmmmm
[13:39] <jcoxon> we can play it by ear i guess
[13:39] <jcoxon> if the forecast gets worse say tomorrow
[13:39] <jcoxon> then we can have a think
[13:39] <jcoxon> i'll work towards having a system working by sat
[13:40] <edwardmoore> ok cool bananas
[13:41] <jcoxon> hmmm need to find a connector for this radio modem
[13:41] <jcoxon> it has a really unhelpful pin out pitch
[13:51] <jcoxon> edwardmoore, i've got a question
[13:51] <jcoxon> for the software for reading the accelerometers
[13:51] <jcoxon> what info do we need
[13:51] <jcoxon> as in is it okay to sample them as quick as possible just from userland (about 15hz)?
[13:51] <jcoxon> do we just want to record directly the data or should it undergo some calculations?
[13:52] <edwardmoore> yeah 15hz should be good
[13:52] <edwardmoore> and then we can do the data crunching on the ground
[13:52] <edwardmoore> may as well just sample raw data up there
[13:52] <jcoxon> so should i just log the data?
[13:52] <edwardmoore> yeah
[13:52] <edwardmoore> in an excel-happy format
[13:52] <jcoxon> i'm thinking about the software to write for radio modem
[13:53] <jcoxon> cause we have a nice link
[13:53] <jcoxon> perhaps send alternative strings of gps pos, acceleromter (say 15 bits of data in one line, and servo snoop?
[13:53] <jcoxon> (while logging them all in the air
[13:53] <jcoxon> )
[13:54] <jcoxon> so it would be:
[13:54] <jcoxon> gps pos
[13:54] <jcoxon> accel data: 1,2,3,4,5,6,7,8,9,
[13:54] <jcoxon> snoop 1,2,3,4,5,6,7,8,9,
[13:56] <jcoxon> actually might be better to have a single string with them all in
[13:56] <jcoxon> quicker

[14:04] <edwardmoore> probably quicker yeah
[14:04] <edwardmoore> but it is a good idea
[14:05] <jcoxon> just found my 200g balloon
[14:05] <mc-> jc, any joy from party days?
[14:05] <jcoxon> hmmm mounting these extra components is going to be a challenge
[14:05] <jcoxon> mc-, tried phoning them this morning no answer
[14:05] <jcoxon> will try again at about 3.30
[14:06] <mc-> ok, also do you have my payload or does steve?
[14:06] <jcoxon> steve has it
[14:07] <mc-> I wondered if it's worth doing a radio range test with my payload?
[14:09] <jcoxon> maybe
[14:09] <jcoxon> right i'll bbl
[14:10] <mc-> ed, I did a rough plan for some rockoon flights
[14:13] <edwardmoore> ooh tell
[14:16] <edwardmoore> but... tell later. have an appojntment
[14:16] <edwardmoore> back tonight
[14:19] <mc-> ok
