[13:31] <jcoxon> hi NeoThermic
[13:31] <NeoThermic> hello
[13:31] <jcoxon> welcome to #highaltitude
[13:31] <NeoThermic> :)
[13:32] <NeoThermic> I came here from your site actually :)
[13:33] <jcoxon> :-D
[13:33] <jcoxon> there aren't that many links to it
[13:34] <NeoThermic> oh, the internet is a fun place to randomly surf :)
[13:34] <jcoxon> hehe
[13:35] <jcoxon> its usually a quiet channel
[13:35] <jcoxon> but were are slowly gaining visitors
[13:36] <NeoThermic> I found it intresting that you only needed to fill out some forms to launch a weather baloon
[13:37] <jcoxon> yeah but its not the sort of thing that would require a licence
[13:38] <jcoxon> they are very safe, considering that meteorlogical balloons are released everyday and there has never been an incident involving one
[13:40] <NeoThermic> Out of intrest, I noted you have a fair few images. Does your site run PHP?
[13:40] <jcoxon> it probably could
[13:40] <NeoThermic> Its just I've got a basic thumbnailing script for image collections as such
[13:41] <NeoThermic> basic as in pages display ala: http://www.neothermic.com/laptop/Images.php
[13:42] <jcoxon> oh cool
[13:43] <NeoThermic> all you have to do is create a /thumbs directory, chmod it to 777, and upload images.php. On the first load, images.php creates the thumbnails, on subsiquent loads, it spots that the thumb already exsists and displays it :)
[13:44] <jcoxon> do the thumbs link to the original pic?
[13:44] <NeoThermic> yes, click them :)
[13:44] <jcoxon> :-) i'm off your site now hehe
[13:44] <NeoThermic> plus, with a tiny bit of CSS, you can change how everything looks :)
[13:45] <jcoxon> cool
[13:45] <jcoxon> thumbnails are probably a good idea
[13:45] <jcoxon> the lack of any really website is that i didn't have time
[13:45] <jcoxon> after the launch the real world took control again
[13:46] <NeoThermic> Eh, the real world, how often that gets in my way :P
[13:48] <NeoThermic> so when you hoping to get pegasus 2 working?
[13:48] <jcoxon> it all depends on me finding a balloon
[13:48] <jcoxon> if i got one tomorrow then i reckon i could launch in a month
[13:48] <jcoxon> the gps/gumstix/phone are all set up
[13:49] <NeoThermic> I thought you had one spare from Pegasus?
[13:50] <NeoThermic> "The balloon itself was got from ebay (its amazing what you can get there) as was a 200g Totex balloon. I actually got two just in case we messed one up while filling them up."
[13:52] <jcoxon> oh yes i do
[13:52] <jcoxon> but i want at least a 1000g balloon
[13:53] <NeoThermic> ahh
[13:53] <jcoxon> want to get a lot higher :_P
[13:54] <NeoThermic> You can, I'm assuming, also get more items in the sensor package with a larger balloon?
[13:55] <jcoxon> yeah
[13:55] <jcoxon> for sensors the limiting factor is my terrible electronics skill
[13:56] <jcoxon> though its going to have 2 temp. sensors and perhaps even a geiger counter
[13:56] <jcoxon> just for fun
[13:56] <jcoxon> though the real aim is to get as high as possible
[13:57] <NeoThermic> I'm sure the boys up in the ISS would be surprised to see it ;)
[13:58] <jcoxon> hehe
[14:00] <NeoThermic> so where abouts are you located then? I note your hostmask says Cambridge Uni (I think), and that you had to contact Wattisham Air Base, but I can't fathom any more detail than that :P
[14:02] <jcoxon> i'm at cambridge right now
[14:02] <jcoxon> but live in suffolk where i launched
[14:02] <jcoxon> have you looked at the google map of the flight path?
[14:02] <jcoxon> it doesn't seem to like IE
[14:03] <jcoxon> (but i use a mac so it works for me!)
[14:03] <NeoThermic> I must of missed the page, got a link?
[14:03] <jcoxon> http://www.mapbuilder.net/UserMap.php?UserName=jamescoxon&Map=pegasus1
[14:04] <jcoxon> are you willing to share that thumbnail php script? would like to give it a go
[14:05] <NeoThermic> sure, lemme locate a copy for you to use
[14:08] <NeoThermic> http://www.neothermic.com/testing/Images.phps
[14:08] <jcoxon> you thinking of doing anything balloony
[14:08] <NeoThermic> just paste into a PHP file and you're good to go
[14:09] <NeoThermic> It does sound intresting, although I lack the eletronic skills to do what you're doing. Plus I don't think Luton airport will enjoy seeing my balloon ;)
[14:10] <jcoxon> :-D
[14:11] <NeoThermic> one of the things I would try is have a small model rocket attached with its own GPS device, and once the balloon reaches what it thinks is peak altitude, to launch the rocket and see how high that goes
[14:11] <jcoxon> rockoon
[14:11] <NeoThermic> ohh, the pun ;)
[14:12] <jcoxon> hehe
[14:12] <jcoxon> am very tempted
[14:13] <NeoThermic> in theory, you could use the serial port, if it ends up spare to initiate the rocket, since most model rockets are eletronically started
[14:13] <jcoxon> yeah, actually i could use a GPIO port
[14:14] <NeoThermic> you would also require a small rig to get the rocket pointing directly up, and far enough out so it doesn't hit the balloon
[14:15] <jcoxon> yeah
[14:16] <NeoThermic> would also be quite fun designing a rocket to carry a GPS device and small mobile phone for broadcast of its location upon landing
[14:16] <jcoxon> that wouldn't be difficult
[14:17] <NeoThermic> weight would be a big consideration
[14:17] <jcoxon> i could lighten the system
[14:18] <jcoxon> and also run everything off a nokia battery
[14:18] <NeoThermic> you could also use more than one propellent to allow more weight
[14:23] <NeoThermic> http://www.srcf.ucam.org/~jac208/pegasus/pictures/IMAG0242.JPG
[14:24] <NeoThermic> there's an object in that image :P
[14:24] <jcoxon> ooo thats a good one
[14:25] phatmonkey (n=phatmonk@65.98.2.81.in-addr.arpa) joined #highaltitude.
[14:25] <jcoxon> where?
[14:26] <NeoThermic> when you zoom in, on the right
[14:26] <NeoThermic> about 1/3rd / 1/4th down the image
[14:28] <jcoxon> ooo i can see it
[14:28] <jcoxon> how strange - perhaps a dead pixel
[14:28] <NeoThermic> nope, if it was a deadpixel, you would spot that in other images :)
[14:29] <NeoThermic> for example, the five deadpixels on my CCD of my camera are very visible on the thumbnails when lined up in this set: http://www.neothermic.com/phpBB/viewtopic.php?t=57
[14:30] <NeoThermic> (actually most are hotpixels, but the same problem in general)
[14:31] <NeoThermic> hmm, mabey it is
[14:31] <NeoThermic> http://www.srcf.ucam.org/~jac208/pegasus/pictures/IMAG0249.JPG has it as well
[14:32] <jcoxon> damn thought we had seen a ufo
[14:32] <NeoThermic> hehe
[14:32] <NeoThermic> could of been following it
[14:32] <jcoxon> hehe
[14:33] Action: NeoThermic waves to phatmonkey
[14:39] <NeoThermic> oh yeah, for the image script you'll also need GD, but that shouldn't be a problem
[15:27] <phatmonkey> ooh, hi!
