[16:17] <jcoxon> hey hotgrits
[16:17] <hotgrits> hi jcoxon
[16:18] <hotgrits> i'm gonna make a balloon someday
[16:18] <hotgrits> ...MAYBE this summer
[16:18] <jcoxon> hehe
[16:18] <jcoxon> its not difficult
[16:19] <jcoxon> even i can do it!
[16:19] <hotgrits> ya, the balloon thing doesn't look difficult. the *recovery*, well ... !
[16:19] <jcoxon> were are you based?
[16:19] <hotgrits> Raleigh, NC
[16:20] <hotgrits> how much money did you put into your project?
[16:21] <jcoxon> ooo cool i've been to NC
[16:21] <hotgrits> really? neat!
[16:21] <jcoxon> got a friend a Duke
[16:21] <hotgrits> Raleigh? Charlotte? Asheville?
[16:21] <jcoxon> and so other friends who live near durham
[16:21] <hotgrits> ah, Durham. Yep, that's my neighborhood.
[16:21] <jcoxon> really nice state
[16:21] <hotgrits> there's a flight from Gatwick straight to RDU ...
[16:22] <jcoxon> ooo cool, i went to NY first
[16:22] <jcoxon> hehe
[16:22] <jcoxon> then went south to savannah
[16:22] <jcoxon> then drove north to NC
[16:22] <jcoxon> but cost, well it depends if you take the gumstix approach
[16:22] <jcoxon> and whether you want to do radio or not
[16:23] <hotgrits> i was planning on using an NSLU2
[16:23] <jcoxon> oooo, cool
[16:23] <jcoxon> usb :-D
[16:23] <hotgrits> ...use a USB-controllable camera ...
[16:23] <jcoxon> yeah
[16:23] <hotgrits> ... and GPS ... and maybe even an altimeter
[16:24] <hotgrits> cost for the NSLU2 is ~ $80 US, iirc
[16:24] <hotgrits> and I'm a HAM (N4JMT) so radio will be a part, though I don't know how I want to use it
[16:24] <jcoxon> not my areas sadly :(
[16:25] <jcoxon> really wouldn't be expensive
[16:26] <hotgrits> I'm figuring around $500 or less. And I have most of the parts here already
[16:26] <jcoxon> yeah
[16:26] <jcoxon> and with radio the failure rate is reduced
[16:26] <hotgrits> I like what you've done with the gumstix but since I don't have much experience with hardware I'll stick to the software approach
[16:26] <hotgrits> true
[16:27] <hotgrits> when's your next launch?
[16:27] Action: jcoxon checks his osx dashboard counter
[16:27] <jcoxon> 55 days
[16:27] <jcoxon> hehe
[16:27] <jcoxon> i've got exams in a month
[16:27] <jcoxon> (actually its 55 days till the launch window opens
[16:27] <jcoxon> )
[16:28] <hotgrits> heh
[16:28] <jcoxon> though this summer is going to be insane
[16:28] <hotgrits> is this a CAA launch window?
[16:28] <jcoxon> well its the one i ask for
[16:28] <jcoxon> (haven't done it yet)
[16:29] <hotgrits> ah, gotcha
[16:30] <hotgrits> wonder how a 802.11 signal would be received if I put an access point in the payload.
[16:30] <jcoxon> i'm going to look into that for pegasus IV
[16:31] Action: hotgrits surfs jcoxon's pegasus webpages
[16:32] <jcoxon> just about to put up my parts list for pegasus III
[16:33] <hotgrits> having a cutdown would be good in my case, as there's a very real possibility of my balloon landing in the Atlantic
[16:34] <jcoxon> yeah
[16:34] <jcoxon> i intend to work on a cutdown device
[16:34] <jcoxon> oops forgot to add that
[16:35] <hotgrits> hmm. might make sense for me to go cheap like you for the first one
[16:36] <hotgrits> i'd love to get movies, too. Another way a USB device could come in handy - usb cameras are cheap
[16:36] <jcoxon> through but solid state memory isn't
[16:36] <jcoxon> though*
[16:37] <jcoxon> however i'd love movies as well
[16:37] <jcoxon> this summer will be doing about 20 launches on my university projects
[16:37] <jcoxon> don't worry i'll get a camera in there
[16:37] <hotgrits> maybe a flash drive for storage? An external laptop hard drive?
[16:38] Action: hotgrits raises the price and payload weight considerably ...heh
[16:38] <hotgrits> I'm too ambitous for just starting. heh.
[16:38] <hotgrits> you're the pro
[16:38] <jcoxon> nah i've had one success and one failure
[16:38] <jcoxon> not a pro
[16:38] <jcoxon> there are people who have done loads of launches
[16:39] <jcoxon> and then there are the scientists who do this for a living
[16:39] <hotgrits> well you can learn just as much or more from failures
[16:39] <jcoxon> going to work with some this summer as well for 2 weeks
[16:39] <jcoxon> oh yeah
[16:39] <jcoxon> probably more
[16:39] <hotgrits> i just don't want any "expensive" failures ...
[16:40] <hotgrits> but i don't know of any restrictions on unmanned radios here in the US, so that's a big plus
[16:40] <hotgrits> my radio can transmit through the whole flight
[16:40] <jcoxon> there don't seem to be any
[16:40] <jcoxon> http://balloon.utarc.org/
[16:40] <jcoxon> these guys are pros
[16:40] <hotgrits> yeah, i've seen their site. Tennessee is right next door to NC, too, though still a bit of a haul to get there
[16:41] <hotgrits> "near" is measured a bit differently in the US than in the UK :)
[16:42] <jcoxon> yeah
[16:42] Action: hotgrits reads through the latest utarc project ... wow ... that's sophisticated!
[16:43] <hotgrits> i've got a lot to learn, apparently
[16:43] <jcoxon> they are good, very good
[16:44] <hotgrits> ah well, nice to meet you jcoxon! I'm jealous of your success, even if its only one
[16:44] <hotgrits> i'll pop in later once i've got the project moving a bit faster
[16:44] <jcoxon> cool
[16:44] <hotgrits> maybe time to get a webpage or wiki together for it
[16:44] <jcoxon> see you around
[16:44] <jcoxon> good idea!
[16:44] <hotgrits> thanks. see ya!
