[09:18] <jcoxon> morning edmoore
[09:19] <edmoore> hello!
[09:19] <edmoore> how's it going?
[09:19] <jcoxon> good thanks
[09:19] <jcoxon> EARs?
[09:19] <edmoore> heading out at about 11
[09:20] <jcoxon> was it yesterday as well?
[09:20] <edmoore> yep
[09:20] <edmoore> the wind is a bit lower today
[09:20] <edmoore> and it's a bit warmer
[09:20] <jcoxon> cool cool
[09:20] <edmoore> and it's the sunday, so all inall it should be better, with luck
[09:20] <jcoxon> haha
[09:20] <edmoore> also fergus should have xubuntu on his eee by now
[09:20] <edmoore> so more excitement
[09:21] <jcoxon> amazing
[09:21] <jcoxon> i'm going to resist dual booting my mb, instead use my linux server for that stuff
[09:21] <edmoore> cool
[09:21] <jcoxon> though its pretty cool that you can run KDE apps natively
[09:21] <edmoore> I had no idea of that
[09:23] <edmoore> show off
[09:23] <jcoxon> its the only thing zeusbot does!
[09:24] <jcoxon> found some cool perl code that works out if a coord inside or outside a polygon
[09:24] <edmoore> could I have a looksee?
[09:24] <edmoore> I like nice algorithms
[09:25] <edmoore> steve seems pretty taken with the idea of ARMs and TNKernals
[09:25] <jcoxon> http://www.pegasushabproject.org.uk/wiki/doku.php/missions:haps:cutdownpolygon.pl
[09:25] <edmoore> might have to try harder on badgerboard v2!
[09:25] <jcoxon> apparrently its not very efficient
[09:25] <jcoxon> you've corrupted him
[09:26] <edmoore> well he realises he once programmed on a computer with a 64k version of linux
[09:26] <jcoxon> hmmmm macbooks have sharper edges then ibooks
[09:26] <edmoore> cut yourself?
[09:26] <jcoxon> no, its just the way i lean my wrists on the laptop when typing in bed
[09:27] <edmoore> I tend to lie down flat, and rest the bottom edge on my chest
[09:27] <edmoore> or with fergus's eee I just found myself plonking it wherever
[09:27] <edmoore> it's an amazing thing
[09:27] <jcoxon> they are very cool, especially the way you can mod them
[09:27] <edmoore> we were talking about putting gps in
[09:28] <edmoore> it would look so awesome mounted on the dash board
[09:28] <jcoxon> it definitly crossed my mind
[09:28] <edmoore> running UKHAS Balloon Track (tm)
[09:28] <jcoxon> i thought of sticking a gumstix in one, have a dual system
[09:28] <jcoxon> you could ssh into over usb
[09:28] <edmoore> ha, awesome :)
[09:28] <edmoore> right, need to grab some breakfast
[09:28] <jcoxon> but now i am broke :-p
[09:28] <edmoore> back 10ish
[09:28] <edmoore> :D
[09:29] <edmoore> bbiab
[09:47] <jcoxon> urgh its so annoying that gps antennas have soo much cable on them

[20:49] <jcoxon> ooooo, a MacGyver film
[20:49] <natrium42> hehe
[20:49] <jcoxon> they have been repeating the series on british tv recently
[20:49] <natrium42> cool
[20:51] <jcoxon> hows things natrium42?
[20:51] <natrium42> pretty good, working on a kiosk-like thing for a contract
[20:52] <natrium42> trying to find a canon powershot a620 or a640
[20:52] <jcoxon> for balloons?
[20:52] <natrium42> no, for the kiosk
[20:53] <jcoxon> oh right
[20:53] <natrium42> hard to find those old models
[20:53] <jcoxon> ebay not helping?
[20:53] <natrium42> and the new ones lack remote capture over usb
[20:54] <natrium42> well, i tried to snipe one today
[20:54] <jcoxon> even with CHDK?
[20:54] <natrium42> but the auction was voided for some reason
[20:54] <natrium42> chdk doesn't add remote capture
[20:54] <natrium42> only shutter release via usb
[20:55] <natrium42> http://rafb.net/p/0eNxoJ81.html
[20:56] <natrium42> those are the only cameras that would fit since they have remote capture *and* hi-speed usb 2.0
[20:57] <natrium42> i really need the good quality since the kiosk is going to be used for facial recognition stuff
[20:57] <jcoxon> sounds complicated
[20:58] <natrium42> http://elyxa.com/kiosk/
[20:58] <natrium42> i shot a few pictures of it 2 days ago
[20:59] <jcoxon> oh wow
[20:59] <jcoxon> thats really cool
[20:59] <natrium42> thanks
[21:00] Action: natrium42 hits ebay again in a desperate attempt
[21:00] <natrium42> i need overnight shipping at this point :P
[21:00] <jcoxon> oh crap - so there is a deadline
[21:00] <natrium42> yeah, there's a show on thursday
[21:00] <natrium42> so i need to whip something up quickly
[21:01] <natrium42> perhaps this one --> http://cgi.ebay.ca/CANON-A620-7-1MP-DIGITAL-CAMERA-W-4X-OPTICAL-ZOOM_W0QQitemZ150241996990QQihZ005QQcategoryZ107900QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

[21:03] <natrium42> not to USA
[21:04] <natrium42> or Canada, rather :)
[21:04] <natrium42> need something in USA or Canada so that they can do overnight shipping
[21:07] <natrium42> anyway
[21:07] <natrium42> any launches coming up? :)
[21:08] <jcoxon> ummmm
[21:08] <jcoxon> working on a launch focusing on cameras
[21:10] <natrium42> testing different cameras?
[21:12] <natrium42> have you tried using UV or polarizing filters, BTW?
[21:12] Simon-MPFH (n=simon@phantom.mpfh.co.uk) left irc: Connection reset by peer
[21:13] <jcoxon> well i'm doing the tracking system and doug from unmannedspaceflight.com is doing the cameras
[21:13] <jcoxon> i think he is going for a powershot with CHDK
[21:13] Simon-MPFH (n=simon@phantom.mpfh.co.uk) joined #highaltitude.
[21:13] <jcoxon> filters will definitly be on the cards
[21:14] <jcoxon> just working on some perl code for a cutdown polygon
[21:14] Action: natrium42 got one of those water-proof cases for his camera which has a built-in UV filter
[21:14] <jcoxon> nice
[21:14] <jcoxon> so a launch for you soon?
[21:15] <natrium42> i don't know how soon, but slowly getting some things together :D
[21:15] <jcoxon> cool cool
[21:15] <natrium42> i am currently considering taking fewer courses this summer
[21:16] <jcoxon> well i've gone back to gumstixs for my flight computers
[21:16] <natrium42> because i have business and contracts going on as well
[21:16] <natrium42> hehe
[21:16] <natrium42> they are nice little computers
[21:16] <jcoxon> developing telits is a nightmare
[21:16] <natrium42> oh yes, certainly
[21:17] <jcoxon> actually the tracking system will be similar to your payload hardware wise
[21:18] <natrium42> oh?
[21:20] <jcoxon> as in a gumstix and a telit

[21:25] <jcoxon> oooo, also i'm going to write some code to send your tracker the radio positions from the flight
[21:25] <natrium42> yay, finally!
[21:25] <natrium42> :D
[21:26] <jcoxon> i'm getting a rtty radio modem off rocketboy
[21:26] <jcoxon> and have worked out how to get serial access to my phone
[21:26] <jcoxon> so i'll send texts to the tracker
[21:26] <natrium42> sounds awesome
[21:28] <jcoxon> might have to be a little manual at first, as in parsing by eye the incoming data
[21:28] <natrium42> is wireless internet expensive in UK?
[21:29] <jcoxon> yes and no
[21:29] <jcoxon> its ?15 a month for 3gbs
[21:29] <jcoxon> but
[21:29] <jcoxon> the contract is 24months
[21:29] <jcoxon> there might be cheaper
[21:29] <jcoxon> or less of a contract
[21:29] <jcoxon> i guess it would be a lot cheaper per message then sms
[21:30] <natrium42> yes, sounds pretty cheap
[21:30] Action: natrium42 hates long contracts too, though
[21:31] <jcoxon> maybe i can find a pay as you go
[21:33] <jcoxon> sms are 12p
[21:33] <jcoxon> its therefore probably not worth it
[21:33] <jcoxon> if i'm launch every couple of months
[21:35] <natrium42> here the cheapest plan is about $70 per month
[21:35] <natrium42> so you are well off :P
[21:36] Simon-MPFH (n=simon@phantom.mpfh.co.uk) left irc: "Leaving"
[21:36] <jcoxon> but i'm thinking i might as well do texts
[21:36] <jcoxon> say 100 updates is ?12
[21:39] <natrium42> if you want, you could also send positions of the chase car
[21:39] <natrium42> i will extend the tracker for that
[21:40] <jcoxon> one step at a time methinks :-)
[21:42] Simon-MPFH (n=simon@phantom.mpfh.co.uk) joined #highaltitude.

[21:51] <mc-> hi natrium
[21:51] <mc-> natrium42
[21:51] <natrium42> hey mc-
[21:52] <mc-> was reading the logs
[21:52] <mc-> can you hack into the shutter on a camera?
[21:52] <mc-> rather than having to use a canon?
[21:52] <natrium42> well, i have to transfer the pictures via usb as soon as they are taken
[21:53] <natrium42> only canon and nikon cameras can do that
[21:53] <natrium42> select few
[21:53] <mc-> why can't the others?
[21:53] <natrium42> i guess it's not a popular feature
[21:54] <natrium42> new canons all lack it as well :/
[21:54] <natrium42> hmm, perhaps i should get Canon PowerShot S80 instead of the A620/640
[21:54] <natrium42> it has a wide angle lens
[21:55] <mc-> are you sure other cameras can't do this?
[21:55] <natrium42> http://capture.sourceforge.net
[21:55] <natrium42> http://gphoto.sourceforge.net/doc/remote
[21:55] <natrium42> those are cameras supported
[21:56] <natrium42> i have never found any other manufacturers that mention that ability either
[21:58] <natrium42> next balloon i fly will also use one of those cameras again
[21:58] <natrium42> so that i can upload pictures live to the tracker
[22:02] <jcoxon> if you trigger the camera via usb you then know that there is a picture to download
[22:02] <mc-> olympus supports this as well
[22:02] <natrium42> mc-, yes, but again... old versions
[22:03] <natrium42> jcoxon, well, yes, you could switch the camera to USB mode and download the image
[22:04] <natrium42> you don't get a live preview, though
[22:04] <natrium42> which is needed for the kiosk
[22:04] <natrium42> for a balloon payload, it's possible
[22:05] <natrium42> although a bit hacky
[22:06] <jcoxon> :-)
[22:07] <natrium42> i have also considered an SD hack
[22:07] <natrium42> you could either (1) switch SD between camera and computer or (2) emulate SD with an FPGA connected to computer
[22:07] <mc-> can you switch into a webcam as a preview?
[22:08] <natrium42> mc-, yes a secondary preview camera is also a possibility
[22:08] <mc-> or 1 cam, and set it up as a webcam
[22:08] <natrium42> if it supports it
[22:09] <natrium42> some cameras also have video out
[22:09] <mc-> then switch to digital cam to take pic
[22:09] <natrium42> so that could be used
[22:10] <natrium42> bbl, gotta get some food
[22:10] <mc-> just sending you a mail
[22:14] <mc-> edmoore, did you launch?
