[01:18] <defy> hey guys :D
[02:34] <defy> so i got my heading/distance math all sorted for my waypoints system, but does anyone know how to determine weather one set of cords is within a certain radius of another set of cords?
[02:36] <defy> so i can trigger my "waypoint reached, move onto the next task"
[03:07] <defy> ah nm, i can just use distance :P
[03:09] <jcoxon> hey defy
[03:10] <jcoxon> can't stay for long
[03:10] <defy> hey :)
[03:10] <jcoxon> just to say that your gpsparser is great
[03:11] <defy> yea? cool :D I'm writing my waypoint sequencer into it
[03:11] <defy> finally got all the math sorted, now its just a matter of program logic
[03:11] <jcoxon> though i'm not sure i understand the time element
[03:11] <defy> the time element is just a unix timestamp
[03:11] <jcoxon> oh right
[03:11] <defy> number of seconds since jan 1st 1970
[03:12] <defy> but since the gumstix doesn't hold its time, it always starts at 0
[03:12] <defy> but setting the gumstix's time from the gps should be quite simple
[03:12] <defy> to get a true time in the logs
[03:12] <jcoxon> might adapt it to take the time from the gps itself
[03:12] <defy> yeah
[03:12] <defy> i was using ntpupdate
[03:12] <defy> but obviously that wont work out in the field
[03:13] <defy> ntpdate rather
[03:13] <jcoxon> yeah
[03:13] <jcoxon> right bed time
[03:13] <jcoxon> its 10 past 3 in the morning
[03:13] <jcoxon> night all

[16:59] <Tiger^> hi jcoxon
[16:59] <jcoxon> hey Tiger^
[17:00] <Tiger^> you've seen my NOTAM, haven't you?
[17:00] <jcoxon> ummm no
[17:00] <Tiger^> oh
[17:00] <jcoxon> is it in the logs?
[17:00] <Tiger^> yeah
[17:00] <Tiger^> A4025/06 - ASCENT OF FREE LIGHT BALLOON WILL TAKE PLACE FM PSN: 524841,62N 0194424,56E. WEIGHT OF BALLON: 1500G. GND 34000M AMSL 20 JUN 09:00 UNTIL 20 JUN 15:00
[17:00] <Tiger^> ;>
[17:00] <Tiger^> it's official
[17:00] <jcoxon> cool
[17:01] <jcoxon> no turning back - just check the car works ;-p
[17:01] <Tiger^> yeah :P
[17:01] <Tiger^> i'm happy to have this extra time
[17:02] <jcoxon> :-)
[17:02] <Tiger^> i'm improving the flight computer pallet
[17:02] <jcoxon> oh right
[17:02] <Tiger^> and the power supply
[17:02] <jcoxon> i'm doing my flight computer now
[17:03] <Tiger^> great
[17:03] <Tiger^> so, it's you launching, macfreak
[17:03] <Tiger^> then hmm... phatmonkey?
[17:04] <jcoxon> in theory i could launch on friday
[17:04] <jcoxon> however the cambridge team won't be ready so i'll have to wait
[17:04] <jcoxon> hopefully i'll have the radio modems intergrated
[17:04] <Tiger^> yeah, don't rely just on the phone ;P
[17:05] <jcoxon> though i haven't actually got the radio modems yet :(
[17:05] <jcoxon> they haven't arrived
[17:05] <jcoxon> also it might require some reorganisation of the wiring - perhaps i should do that tomorrow

[18:26] <ehj20> Bah, it turns the pin function diagram from the gps manufacturer is completely fictitous!
[18:28] <ehj20> Thought I was going mad
[18:31] <ehj20> jcoxon: did you manage to get a VCC supply from the waysmall serial port?
