[00:01] <jcoxon> hmmm
[00:01] <jcoxon> well i'm going to head to bed
[00:01] <jcoxon> had a busy day
[00:01] <jcoxon> cya guys
[00:01] <jcoxon> chat soon
[00:01] jcoxon (n=jcoxon@jac208.caths.cam.ac.uk) left irc: "Leaving"
[00:22] <macfreak4> well i just learned two things:
[00:23] <macfreak4> the laptop can run at voltages much lower than it is rated for, and that the regulator does not turn off due to low voltages
[00:23] <defy> lol
[00:23] <defy> so one good thing, and one bad thing? :P
[00:26] <macfreak4> yeah i suppose...
[00:27] <macfreak4> although because the laptop can run at lower voltages, it doesnt nesessarily matter if the regulator doesnt turn off
[00:27] <macfreak4> it'd just be a waste of some power
[02:08] <macfreak4> anyone still on?
[02:20] <defy> yea, I'm just playing with mmtty
[02:33] <macfreak4> o okee
[02:34] <macfreak4> i just mounted the lithiums... they should be ok
[02:41] <defy> what are you using for housing
[02:48] <macfreak4> of the whole payload?
[02:48] <macfreak4> a styrofoam (polystyrene) cooler from WalMart ;)
[02:49] <macfreak4> painted bright fluorecent orange w/ bottom covered w/ aluminum foil (for radar reflection; FAA requirement)
[02:49] <defy> cool
[02:50] <macfreak4> there was a plastic handle that I cut out with a dremel tool and put small 4"x4" plexiglass over for both cameras
[02:50] <defy> aluminum foil is enough ? sweet
[02:50] <macfreak4> i hope
[02:50] <macfreak4> lol
[02:50] <defy> sweet, thats more or less how i plan on doing mine as well
[02:50] <macfreak4> o cool
[02:50] <defy> might make a perspex done and pivot one of the cameras vertically with a servo
[02:50] <defy> dome*
[02:50] <macfreak4> i'm using a mirror
[02:50] <macfreak4> and servo
[02:51] <defy> cool
[02:51] <macfreak4> more or less because i forgot that i might like to look down, too :P
[02:51] <defy> hehe
[02:51] <macfreak4> but because I don't have a servo controller, i had to hack a servo to be a "normal" dc motor
[02:51] <defy> I'm just playing around with this mmtty software, either i cant figure out what i'm doing or there aren't any valid signals around here
[02:51] <macfreak4> oh?
[02:52] <macfreak4> you're trying it out on the air?
[02:52] <defy> just receiving yea
[02:52] <macfreak4> hmm
[02:52] <macfreak4> do you have 2 computers and a male-male stereo cable/
[02:52] <defy> yeah
[02:53] <macfreak4> try it computer to computer, with the tx computer's speaker output to the rx computer's input
[02:53] <defy> are you using the line in or the mic?
[02:54] <macfreak4> line in should work
[02:54] <macfreak4> just make sure to set your computer to use it
[02:56] <macfreak4> yea the program was confusing at first, but it makes more sense after a while
[02:58] <defy> I get a lot of decoded garbage on the screen
[03:00] <macfreak4> there's a black bar under the SQ button and above the ATC button that controls the threshold
[03:00] <macfreak4> you can adjust that, which might fix the problem
[03:00] <macfreak4> make sure your mark shift bw and av settings are the same
[03:01] <defy> yea thats the squelch threshold isnt it?
[03:01] <macfreak4> yea
[03:03] <macfreak4> "1200 gram size will take a full six pound payload to 100,000 feet"
[03:03] <macfreak4> lol im using a 2200gram balloon
[03:04] <macfreak4> for six pounds
[03:04] <defy> damn
[03:04] <defy> i have no idea what size mine is
[03:04] <macfreak4> where did you get it?
[03:04] <defy> but thats what i get for 45c
[03:04] <macfreak4> oh lol
[03:04] <macfreak4> thats a good price!
[03:04] <defy> ebay :P I'm probably going to get some brand new ones before i try launching
[03:04] <macfreak4> o same
[03:07] <defy> i really need another transceiver to test this properly
[03:08] <macfreak4> yea...
[03:08] <macfreak4> well i got good news today
[03:08] <macfreak4> my physics teacher sent out an email to the staff looking for ham operators
[03:08] <macfreak4> and already two students have said that their dads are hams and might like to help out
[03:08] <defy> awesome
[03:09] <macfreak4> because i don't think i can get my license in time
[03:09] <macfreak4> (launch is less than 4 weeks away)
[03:09] <defy> man you're studying physics too? thats cool, I'm thinking about starting uni again next year and maybe doing physics
[03:09] <macfreak4> yea i like physics a lot
[03:09] <defy> ah yea, i've been studying for my license
[03:10] <macfreak4> i dont even have a book yet :(
[03:10] <macfreak4> but i'll get my license eventually...
[03:11] <defy> cool
[03:11] <defy> what kind of prerequesets did you need going into physics
[03:11] <defy> mostly math stuff?
[03:14] <macfreak4> oh sorry im a high school freshman
[03:15] <macfreak4> everyone has to take physics
[03:15] <macfreak4> (am assuming the question was refering to university)
[03:19] <macfreak4> which reminds me i have a test tomorrow
[03:19] <macfreak4> :(
[03:20] <icez> uhoh
[03:20] <icez> you're already in physics?!
[03:21] <macfreak4> yea
[03:21] <macfreak4> AP Chemistry next year, too
[03:21] <icez> weird
[03:21] <macfreak4> why?
[03:21] <icez> i can't take physics before chemistry here
[03:21] <macfreak4> oh yeah my school does it differently...
[03:22] <macfreak4> and then when new students come in their junior or senior year they have to be in a freshman class because they haven't had physics yet :P
[03:22] <icez> but physics is really cool
[03:22] <macfreak4> yea
[03:22] <macfreak4> where are you located?
[03:22] <icez> arizona
[03:23] <macfreak4> oh
[03:23] <icez> you?
[03:23] <macfreak4> (Missouri)
[03:23] <icez> ok
[03:23] <macfreak4> i find it a very nice place to launch balloons -- no oceans. at all. lol
[03:24] <icez> yeah
[03:24] <icez> i have trouble launching anything here
[03:24] <defy> sweet, i left highschool about 8 years ago :P havent been back to school since
[03:24] <macfreak4> oh
[03:26] <icez> i'm almost done:p
[03:26] <macfreak4> with high school?
[03:26] <icez> yeah
[03:26] <macfreak4> oh shit i gotta do some studying
[03:26] <macfreak4> cya
[03:27] <icez> cya

[08:54] <defy> hey there :)
[08:54] <jcoxon> hey defy
[08:56] <defy> hey did your gpsstix get a fix without an antenna?
[09:12] <jcoxon> nope
[09:12] <jcoxon> but i am also inside
[09:12] <jcoxon> yours arrived yet?
[09:13] <defy> yup, no fix, but I'm also inside and have no antenna, i had a 6 foot cable with an sma plug on the end but that didn't help...spose i should go out and get a proper antenna
[09:13] <jcoxon> gps signals are really week
[09:14] <defy> yea, i couldnt find a cat5 cable long enough that let me hang it outside
[09:14] <jcoxon> hehe
[09:15] <defy> this rtty is pretty cool, I got it working over the air with my ham radio and an old frs
[09:15] <jcoxon> oooo
[09:16] <defy> i just hold the frs to my laptops mic while its transmitting and the decoder actually picks it up and decodes it perfectly
[09:16] <jcoxon> oooo/
[09:16] <jcoxon> so its not data
[09:16] <defy> its text
[09:16] <jcoxon> whats actually being transmitted?
[09:16] <jcoxon> sounds?
[09:16] <jcoxon> (i guess it is a radio
[09:16] <jcoxon> )
[09:17] <defy> yea just beeps and bops
[09:17] <defy> its like 5bit morse code
[09:18] <defy> but what I'm not finding is very good linux support for it, i cant find any transmitting software that isn't for X windows =/
[09:18] <jcoxon> might need a bit of hacking
[09:20] <jcoxon> right, just ordered my gps antenna
[09:20] <defy> sweet
[09:20] <jcoxon> £12 in total
[09:44] <jcoxon> i guess you've seen: http://linpsk.sourceforge.net/
[09:50] <defy> yeah
[09:50] <defy> requires X =/
[10:22] <jcoxon> grrrrr
[10:22] <jcoxon> how good is your programming :-d
[10:24] <defy> depends on the language, I'm mostly a web developer :(
[10:24] <defy> modperl/mysql stuff...not that handy for the gumstix
[10:24] <jcoxon> true
