[00:01] <natrium42> make sure to use the non-ubuntu version of xchat
[00:01] <natrium42> since the ubuntu one is outdated
[00:02] <natrium42> wait
[00:02] <fnoble> what benifits will the latest version bring me?
[00:02] <natrium42> i mean, not the xchat-gnome package, but the xchat package

[00:13] <natrium42> oh, the 9" version is out already?>
[00:14] <fnoble> not in the us, i think in europe and asia only

[03:47] <akawaka> and another one with a timechart showing the DSN schedule for all 36 missions they are doing right now
[03:48] <akawaka> went to the spacecraft assembly building too
[03:48] <akawaka> everything else was pretty busy
[03:48] <natrium42> not the cleanroom?

[10:20] <jcoxon> need to sort out some code to extract the corner coods from the polygon.kml to make it easy to make hte polygons
[10:20] <Laurenceb> look at my aerosol code
[10:20] <Laurenceb> it loads a kml cutdown file off the SD card :D
[10:20] <jcoxon> its just a matter of parsing in perl

[19:12] <akawaka> johan is working on a offline google maps viewer
[19:12] <jcoxon> oh now that would be cool
[19:12] <jcoxon> by caching the area?
[19:13] <akawaka> no, he just wrote his own windows app that downloads the image data from google using their protocol, but saves it locally too
[19:14] <jcoxon> cool idea
[19:15] <jcoxon> i have gps maps on my phone :-), have been using that to find payloads
[19:18] <akawaka> not a lot of roads where our predicted landing sites are
[19:19] <jcoxon> fair enough
[19:33] <fnoble> have you heard of the openstreetmap?
[19:33] <fnoble> i think all their data source is available freely
[19:34] <akawaka> hadn't heard of that, looks interesting
[19:34] <akawaka> we really need image data though
[19:35] <akawaka> not sure if johan will release this, but he'll be happy to share it with balloon people once hes done
[19:35] <fnoble> look up gpsdrive
[19:36] <fnoble> they include some perl scripts for downloading nasa landsat images
[19:36] <jcoxon> there is also nasa worldwind
[19:36] <fnoble> which are free for use
[19:36] <fnoble> and gpsdrive itself can display them offline i think, overlaying a gps position
[19:36] <akawaka> yeah, we have the nasa stuff too
[19:37] <akawaka> he's hoping to write an all in one app, download from various sources
[19:37] <akawaka> 2d and 3d views
[19:37] <akawaka> etc
[19:37] <fnoble> thats pretty cool
[19:38] <akawaka> yeah, now i need to work on redirecting his attention back to the ps3:)

[19:47] <Sarge753> Hey everyone
[19:47] <Sarge753> When is the next planned launch in the UK?
[19:49] <Sarge753> I am really interested in designing my own high altitude balloon
[19:51] <Sarge753> I am looking into a budget flight computer.
[19:54] <Sarge753> I think I am going to use a Nokia 6210 + serial cable ~£15, cheap gps with serial interface ~£15 + servo for cutting the line. All connected to an arduino
[19:54] <Sarge753> Plus a TinyTrak3 and a Canon camera with the CHDK firmware
[20:12] <jcoxon> sounds like an excellent idea
[20:12] Action: jcoxon will be back and forth a bit for the next hour
[20:12] <jcoxon> the next launch won't be for a few weeks
[20:12] <jcoxon> not sure who it'll be yet

[20:54] <natrium42> i found a guy yesterday to ship it to me quickly
[20:54] <natrium42> should get it tomorrow
[20:55] <akawaka> chdk supports it i see
[20:56] <natrium42> yep, digic II
[20:56] <akawaka> i'm considering shooting in raw mode for our next balloon
[20:56] <natrium42> how many bits does the sensor use per pixel?
[20:58] <akawaka> i think its 10 or 12-bits per element per pixel
[20:59] <natrium42> neat
[21:04] <akawaka> i figure it'll help with UV stuff
[21:06] <edmoore> fnoble: ping
[21:06] <natrium42> not sure if it would help filter it
[21:06] <natrium42> (the haze)
[21:07] <akawaka> not sure what kind of uv artifacts to expect really
[21:07] <akawaka> the haze?
[21:07] <natrium42> a filter just removes some of the haze in the atmosphere

[22:01] <edmoore> and some rigging hockery pockery
[22:02] <jcoxon> oh right, so parafoil still not glider
[22:02] <edmoore> oh sorry yes
[22:02] <edmoore> well, it does glide
[22:02] <jcoxon> i thought you were going to make a glider
[22:02] <edmoore> no, that would be a pita
[22:03] <edmoore> and, as you say, *another* project
[22:03] <jcoxon> :-)
[22:05] <jcoxon> so Big EARS was a success?
[22:05] <edmoore> yeah, great fun
[22:05] <edmoore> rockets are a laugh
[22:05] <jcoxon> :-)
[22:06] <edmoore> and seeing all of them keeps re-inforcing in my mind how ludicrously fast our sounding rocket is going to be
[22:06] <edmoore> it really will take some engineering
[22:06] <jcoxon> oh yeah, ed if it works it'll be amazing
[22:07] <jcoxon> i expect to be invited to see the launch
[22:07] <edmoore> naturally!
[22:07] <jcoxon> heheh
[22:07] <edmoore> had a wave round of the particular motor we're designing it around
[22:08] <edmoore> gives a nice perspective
[22:08] <jcoxon> so is the project on course?
[22:08] <edmoore> yep, at the moment it's all going pretty well
[22:08] <jcoxon> excellent
[22:09] <edmoore> Tigga is actually building the launch truss with rob
[22:09] <edmoore> say hello tigga
[22:09] Action: Tigga waves
[22:09] <edmoore> I think it'll go together quite quickly after they finish exams this week
[22:09] <edmoore> would you say?
[22:09] <jcoxon> damn those early engineer exams
[22:09] <edmoore> and me? I need to help rosie unpack her car as I promised to earlier
[22:09] <edmoore> back 11ish!
[22:10] <Tigga> aye, I don't know if Rob has actually built the test
[22:10] Sarge753 (n=chatzill@78.32.64.12) left irc: "ChatZilla 0.9.82 [Firefox 2.0.0.14/2008040413]"
[22:10] <Tigga> he said he was going to
[22:10] <Tigga> if he has, then we can test it, make sure sums are right, and then build the thing
[22:10] <jcoxon> cool cool
[22:11] <jcoxon> its the potential launch at X-Prize?
[22:11] <Tigga> aye
[22:12] <Tigga> transport is a bit of an issue - it's a rather long launch rail
[22:13] <jcoxon> ship it early
[22:13] <jcoxon> for big balloon campaigns they ship about a month in advance
[22:13] <jcoxon> then sit around doing nothing as all the kit has gone
[22:15] <Tigga> well, we're probably going to make it in two parts. If we're going to do any test launches with it we'll need to cart it around the country, and it looks like it's a bit too long to strap to the top of a car
[22:15] <jcoxon> yeah
[22:16] <Tigga> anyways, more cramming needed, ciao
[22:16] <jcoxon> cya
