[11:48] <jcoxon> though i've just tested it and it seems to be fine
[11:49] <rjharrison> has he done a lunach?

[11:49] <jcoxon> maybe this afternoon
[11:49] <rjharrison> Cool
[11:49] <jcoxon> no audio
[11:49] <rjharrison> Need some sample data really to test his broblem
[11:49] <rjharrison> problem
[11:52] <jcoxon> is there a way to pass more custom data yet to the tracker?
[11:53] <jcoxon> e.g int_temp

[17:32] <jcoxon> any experience with radios?
[17:32] <howely> no
[17:33] <jcoxon> okay well the first thing to start with is giving http://wiki.ukhas.org.uk a read
[17:33] <howely> i have done thata
[17:33] <howely> that
[17:33] <howely> im hoping to send a payload of 8 cameras
[17:33] <jcoxon> okay well then the basic setup is a GPS, a microprocessor such as an arduino and then some form of communcation - either a mobile phone or a 10mW radio
[17:34] <howely> ok gtg

[17:51] <jcoxon> thats pretty impressive
[17:51] <jcoxon> the current record is 420km
[17:51] <gb73d> well i spent a few hours improving the feeder system too
[17:51] <gb73d> ok will try to improve it
[17:52] <jcoxon> hehe
[17:52] Action: natrium42 should put distances onto the signal lines in the tracker...
[17:53] <gb73d> i mada 435 mhz gp but whern i measured the swr the 446mhz gp was a bit better 1.5 v 1.7
[17:53] <gb73d> also found i have a feed thru capacitor inline
[17:53] <gb73d> not a b2b bnc as i thort
[17:54] <gb73d> the jim 75 preamp is set to 20db with the 225-1500 mhz bandpass filter

[17:55] <gb73d> i do get lpd qrm tho
[17:56] <jcoxon> :-)
[17:56] <gb73d> am going to try trimmin gthe 435 gp to a better swr
[17:56] <jcoxon> i need to make a better setup
[17:56] <gb73d> ant is 57m asl
[17:56] <jcoxon> but i'm often in the field doing the launches
[17:56] <jcoxon> :-)
[17:56] <gb73d> i wish i had a big yagi beam on a rotator
[17:57] <jcoxon> so do i
[17:57] <jcoxon> the cusf guys have their rotator setup to auto track the balloon using the position data off the server
[17:57] <gb73d> thats really cool
[17:58] <LazyLeopard> Just hope they weren't trying to follow the payload that played gps games... ;)

[19:13] <rjharrison> Hi all
[19:13] <rjharrison> Quick question for the electronic buffs
[19:14] <rjharrison> I have the gps linked to the avr via a serial connetion
[19:14] <rjharrison> now I have put a pin in the middle to send data in for testing
[19:14] <rjharrison> ie when the gps is there
[19:15] <rjharrison> However the avr never sees the signals
[19:15] <rjharrison> In fact if I do loop back in to the uart sentding the data it doesn't even see the sent data
[19:15] <rjharrison> Whats happening the GPS seems to be sucking the data into it
[19:16] <rjharrison> I have programmed the gps for no output on the nmea tty lines

[22:39] <edmoore> well, i guess it's conceivably 30nm
[22:39] <SpeedEvil> A bit of computation would get you a range
[22:40] <jcoxon> natrium42, no worries

[22:44] <SpeedEvil> More simply - the coast doesn't look right
[22:44] <SpeedEvil> The shuttle departs to the east.
[22:44] <SpeedEvil> (ish)
[22:45] <SpeedEvil> Hence we're looking east.
[22:46] <SpeedEvil> If we assume canaveral is under the launch - the coast is all wrong.
[22:46] <russss> well, the sun is behind it, so it's either a cape canaveral launch in the morning or a Vandenberg launch in the evening.
[22:47] <russss> or not in the US I guess ;)

[22:48] <russss> but the thing is if you wanted to time going skydiving to coincide with a launch, the shuttle is your best bet because they have the narrowest launch window.

[22:49] <SpeedEvil> russss: especially for rendevous.
[22:49] <jcoxon> actually might be able to come along
[22:50] <russss> SpeedEvil: yeah that's what I meant. The last non-ISS shuttle mission was the last Hubble one wasn't it?
[22:50] <russss> that was a while ago
[22:50] <N900evil> I forgot aboujt vandenburg
[22:51] <jcoxon> russss, ooo i could check out that G5
[22:51] <russss> jcoxon: it has no RAM or graphics
[22:51] <russss> SpeedEvil: orrr it could be a Guyana launch
[22:53] <jcoxon> russss, did you get to the bottom of the model?
[22:53] <jcoxon> as in what it is?
[22:53] <russss> it's a G5
[22:53] <russss> because it has the ludicrous liquid-cooled heatpipe plumbing
[22:53] <russss> it appears to be dual-CPU
[23:00] <jcoxon> much water damage?
[23:00] <russss> none visible
[23:00] <russss> it has no drives, either
[23:00] <russss> so most of the stuff which could be water damaged isn't there.
[23:05] <jcoxon> i'll find some bits then and bring them along

[23:16] <jcoxon> russss, is there a monitor at the hackspace/
[23:16] <jcoxon> ?
[23:16] <russss> er
[23:16] <russss> only the Apple one with the DVI input
[23:16] <russss> so as long as you've got DVI you're fine.
[23:16] <russss> someone stole our VGA monitors.
[23:19] <jcoxon> okay, will have a route
