[12:10] <Laurenceb> Hi all
[12:11] <Laurenceb> Ultrahab is coming on... It now has phone, gps and cutdown
[12:11] <Laurenceb> and I fixed the programming port, there was a broken via
[12:11] <Laurenceb> all the tronics is done apart from soldering on the radio cable
[12:17] <jcoxon> nice work
[12:19] <jcoxon> i'm still working on my gps parser :-D
[12:19] <jcoxon> well actually its done now
[12:19] <jcoxon> just need to test it when the damn thing gets a gps lock
[12:20] <Laurenceb> cool, have you seen arduino?
[12:20] <jcoxon> i've got one
[12:20] <jcoxon> arrived about 2 days ago
[12:20] <Laurenceb> is it any good?
[12:20] <jcoxon> ummm
[12:21] <jcoxon> haven't really pushed it yet
[12:21] <jcoxon> but i've managed to make led blink and also fade up and down
[12:21] <Laurenceb> I was thinking of loading the firmware onto an avr
[12:21] <Laurenceb> to make my own
[12:21] <jcoxon> it seemed really easy to program
[12:21] <Laurenceb> yes thats why I like it
[12:21] <jcoxon> and there are good examples on hte net e.g. gps parser etc
[12:22] <Laurenceb> bascom avr is very easy but its not open source and it seems to be a little bit buggy
[12:23] <Laurenceb> but floating point on avrs is suprisingly fast, all the glider code will run in 3ms
[12:23] <Laurenceb> did an experiment yesterday
[12:24] <Laurenceb> I came up with a flying wing design yesterday
[12:25] <jcoxon> i was going to use one to make a simple payload for testing the deployment of the parafoil
[12:25] <Laurenceb> using just 4 thermopiles, 2 atmega8s and 3 opams
[12:25] <Laurenceb> -opamps
[12:26] <Laurenceb> if you have 4 thermopiles arranged pointing front/rear , left/right
[12:26] <Laurenceb> its sensitivity changes with the weather
[12:27] borism (n=borism@195-50-215-54-dsl.krw.estpak.ee) left irc:
[12:27] <jcoxon> interesting
[12:27] <Laurenceb> but it you have sensors pointing up/down and then forwards or backwards at an angle ie 45 degrees to straight ahead
[12:27] <Laurenceb> you can do the same thing as a 6 sensor system in software
[12:28] <Laurenceb> it'd need a little amplifier with 3 opamps, and 1 avr for flight contol, one for gps parsing, and sensors
[12:29] <Laurenceb> - a six sensor array with a z axis ie vertical pair can also do this, but of course its more complex
[12:29] <Laurenceb> and with this system you can have a little cluster of sensors say on the wing trailing adge and they will all have line of sight to the ground
[12:32] <jcoxon> what sort of altitude will ultrahab reach?
[12:34] <Laurenceb> 40km I hope
[12:34] <Laurenceb> but I'll need 1500gram balloon for that
[12:35] <jcoxon> doesn't rocketboy have any?
[12:36] <Laurenceb> hope only 1200gram
[12:36] <Laurenceb> -no
[12:36] <jcoxon> oh
[12:37] <Laurenceb> that would make about 38/39km
[12:38] <Laurenceb> nothing on ebay

[16:41] <jcoxon> hey edwardmoore
[16:41] <jcoxon> gps parser finished
[16:42] <jcoxon> also logs to a file
[17:08] <edwardmoore_> hi jcoxon
[17:08] <edwardmoore_> sorry my window didn't 'boing' when you said my name
[17:08] <edwardmoore_> silly thing
[17:08] <edwardmoore_> guess it was the spurious _ what done it
[17:08] <jcoxon> yeah must of been
[17:09] <jcoxon> so i have nice float and int variables for you
[17:09] <jcoxon> for the VTG, GGA and RMC
[17:09] <jcoxon> just looking into how to convert them into a nicer form
[17:09] <jcoxon> something like decimal
[17:17] <max0> hey jcoxon
[17:19] <jcoxon> hey max0
[17:20] <edwardmoore_> what are they now then?
[17:20] <jcoxon> they are raw floats
[17:20] <jcoxon> so e.g. 5252.160
[17:20] <edwardmoore_> so they've not been converted from degrees.mins then
[17:20] <jcoxon> no
[17:21] <edwardmoore_> ok well that ain't too tricky
[17:21] <max0> jc i have openwrt on my 850g :)
[17:21] <jcoxon> max0 cool
[17:21] <jcoxon> you just using it for a router?
[17:21] <max0> i have also have a rockwell gps :)
[17:21] <jcoxon> haha
[17:22] <jcoxon> sounds like Peg IV to me
[17:22] <jcoxon> i actually never launched it in the end!
[17:22] <max0> not dared solder it yet
[17:22] <max0> hehe how come :(
[17:23] <jcoxon> on the launch day the phone started playing up
[17:23] <jcoxon> not exactly sure
[17:23] <jcoxon> and then it got retired to acting as a router
[17:23] <jcoxon> perhaps it'll rise again
[17:23] <jcoxon> edwardmoore_ do you want me to send you the code?
[17:24] <edwardmoore_> yes please
[17:24] <max0> ive just coded a few rss feeds for openwrt with wget and sed for news and weather
[17:24] <max0> :)
[17:27] <jcoxon> http://www.srcf.ucam.org/~jac208/pegasus/gpsparser.c
[17:27] <Superkuh> OpenWRT code for the 850g? Put it on the web....oh. Sweet!
[17:28] <max0> its a simple shell script which uses wget and sed if you want a copy ill put them on pastebin
[17:30] <jcoxon> hi Superkuh
[17:30] <edwardmoore_> oh btw jcoxon do you wanna swing the bot over?
[17:32] <jcoxon> yes please
[17:33] <jcoxon> was just thinking that
[17:33] <jcoxon> do you mind emailing me details
[17:33] <jcoxon> i'll just copy the config across
[17:33] <edwardmoore_> ok well if you wanna swing by highaltitude99 we can keep boring chat away from these fine folks
[17:33] <edwardmoore_> oh ok
[17:33] <edwardmoore_> np
[17:36] <edwardmoore_> emailed it to googlemail
[17:37] <jcoxon> oh
[17:37] <jcoxon> hmmm
[17:37] <jcoxon> do you mind sending to my hermes
[17:37] <jcoxon> am on my linux console right now
[17:37] <edwardmoore_> ok
[17:37] <jcoxon> can check hermes through ssh
[17:38] <edwardmoore_> done
