[02:06] <natrium42> Laurenceb, hey
[02:11] <Laurenceb> hey there
[02:11] <Laurenceb> ever written code for phones?
[02:12] <Laurenceb> I'm looking at java on the ericsson t610, you can do quite a lot
[02:12] <Laurenceb> unfortunately not talk to the camera
[02:12] <natrium42> haven't used mobile java, sorry
[02:14] <Laurenceb> I'l have to try it
[02:15] <natrium42> are you using that phone on your payload?
[02:16] <Laurenceb> yes
[02:16] <Laurenceb> its cheap and looks like an interesting platform for development

[09:32] <jcoxon> morning jatkins
[09:34] <jatkins> I'm hoping to get a balloon and parachute ordered by the end of today
[09:34] <jatkins> as my payload's nearly finished
[09:35] <jatkins> I've been looking at the balloon data page on the wiki, just wondering if there's a way to estimate burst altitude

[09:47] <jatkins> also, I was just reading your site about pegasus 1 - did you include a cut-down device or just wait for balloon burst?

[10:15] <jatkins> I've nearly finished linking up the gps
[10:15] <jatkins> got it working with my pc, just finishing off doing the rs-232 with the arduino
[10:16] <jatkins> on the arduino, you just use the digital pins for rs-232, so it's really easy
[10:16] <edmoore> awesome, well done
[10:16] <edmoore> camera interfaced?
[10:16] <jatkins> yep
[10:16] <jatkins> just radio to do
[10:16] <edmoore> cool, sounds grand
[10:16] <edmoore> jcoxon_: ping
[10:17] <edmoore> what are your thoughts on the radio?
[10:17] <jatkins> 434mhz, just for downlinking gps data
[10:20] <jatkins> is radiometrix a good place to get a module from?
[10:21] <edmoore> yes, it is indeed
[10:21] <jatkins> ok, thanks
[10:22] <jatkins> does radio usually communicate on rs-232?
[10:22] <jatkins> to the arduino

[19:02] <edmoore> hi jcoxon
[19:04] <jcoxon> hey edmoore
[19:08] <edmoore> put one pic up
[19:08] <jcoxon> yay
[19:08] <edmoore> am on wireless which is sloooow
[19:09] <jcoxon> in the bar?
[19:09] <edmoore> but will stick the rest up when i get back to me (now unrestricted) room
[19:09] <edmoore> yes
[19:09] <jcoxon> cool cool
[19:10] <jcoxon> i've now shifted my website to dokuwiki
[19:10] <edmoore> oooh
[19:10] <jcoxon> and got google adsense and analytics
[19:10] <edmoore> very nice
[19:10] <edmoore> I like it
[19:10] <jcoxon> cool picture
[19:10] <jcoxon> http://www.pegasushabproject.org.uk/fhalp2/P1010255.JPG
[19:12] <edmoore> just after cutdown I think
[19:13] <jcoxon> nice view of cambridge
[19:17] <jcoxon> edmoore, did the cutdown fire?
[19:17] <edmoore> yep
[19:17] <edmoore> appears to have
[19:17] <jcoxon> now thats interesting
[19:18] <edmoore> I can't confirm that though
[19:18] <edmoore> tis in my car

[19:35] <jcoxon> right i've worked out the orientation
[19:37] <jcoxon> it is cambridge, from the north west, you can see bar hill where the m11 meets the a14
[19:39] <edmoore> ?
[19:39] <edmoore> oh yes
[19:40] <akawaka> cool pic
[19:42] <edmoore> so it landed within 300m of cb24 4ra
[19:42] <jcoxon> oh right
[19:42] <jcoxon> was going to ask
[19:43] <edmoore> so not even bar hill
[19:43] <edmoore> odd
[19:43] <edmoore> really will be interested to see the logs on this'n
[19:44] <jcoxon> did you check out hte photos when you went to collect it?
[19:46] <jcoxon> it was the perfect day for a launch
[19:49] <edmoore> yes
[19:49] <edmoore> i did
[19:53] <edmoore> sorry, network is playing silly
[19:53] <edmoore> dodgy wireless
[19:57] <jcoxon> :-)
[20:07] <edmoore> so what next jcoxon
[20:07] <edmoore> ?
[20:07] <jcoxon> well
[20:07] <jcoxon> i'm not sure
[20:07] <jcoxon> as in what?
[20:14] <jcoxon> hmmmmm
[20:14] <jcoxon> our predictions we out by quite a bit
[20:14] <jcoxon> it landed 7km away from launch
[20:14] <jcoxon> haha
[20:16] <natrium42> hey edmoore & jcoxon
[20:16] <natrium42> where are the pics?
[20:16] <edmoore> hi natrium42
[20:16] <natrium42> :)
[20:17] <akawaka> what was the prediction?
[20:17] <jcoxon> natrium42, only one pic up at the mo
[20:17] <jcoxon> http://www.pegasushabproject.org.uk/fhalp2/P1010255.JPG
[20:17] <jcoxon> akawaka, we used the uni of wyoming
[20:17] <natrium42> ah, wow, nice
[20:18] <jcoxon> it placed it landing much further south
[20:18] <natrium42> is that ascent?
[20:18] <jcoxon> we think thats apogee
[20:18] <jcoxon> as i edmoore has the payload i haven't got hte log off it yet
[20:18] <akawaka> any idea yet if the flight time was as predicited, or much shorter?
[20:18] <natrium42> "You don't have permission to access /fhalp2/ on this server."
[20:18] <natrium42> bah :P
[20:19] <jcoxon> oh its only one pic
[20:19] <jcoxon> more soon!
[20:19] <natrium42> good, good :)
[20:19] <jcoxon> once edmoore leaves the bar
[20:19] <edmoore> you make me sound like a drunkard
[20:19] <jcoxon> akawaka, our ascent was a lot quicker
[20:19] <jcoxon> hehe, was sort of the plan
[20:20] <jcoxon> akawaka, the uni of wyoming predictor has a set ascent rate
[20:24] <jcoxon> its interesting - if the cutdown did work then either we lost radio at cutdown or the radio module went wrong and the gm862 carried on
[20:24] <edmoore> maybe cutdown caused a voltage drop or something?
[20:25] <jcoxon> yeah
[20:27] <jcoxon> i guess the log will reveal all
[20:43] <natrium42> cutdown was on the same battery??
[20:45] <jcoxon> yup
[20:45] <jcoxon> twas all on a single supply
[21:09] <MetaMorfoziS> The next sentence will be true. The previous sentence is false.

[23:23] <edmoore> there are a million ones of the landing site which i've not included
[23:23] <edmoore> just 2 of them
[23:23] <jcoxon> fair enough
[23:23] <jcoxon> so the camera battery works well then
[23:26] <jcoxon> about the blurredness
[23:26] <jcoxon> will the light sensor be in the lens or could it be external (and so do we block it with the case
[23:29] <edmoore> not sure, but you might be right
[23:29] <edmoore> worth having a loook
[23:30] <jcoxon> cause they are really blurred
