[17:49] <DanielRichman> Red light turn green - guess which GPS just got a fix!
[17:49] <DanielRichman> Atmega + lassen iq success!
[17:49] <jcoxon> hehe
[17:49] <jcoxon> good work
[17:49] <jcoxon> and good use of leds
[17:50] <DanielRichman> You can say so much with one led
[17:50] <DanielRichman> it's a tri-colour (red & green, optional mix to yellow)
[17:50] <SpeedEvil> Or one LED.
[17:50] <SpeedEvil> Morse++ +++ + +++ + ++
[17:50] <DanielRichman> pff.
[17:51] <DanielRichman> Red/off pulsing => starting up, red/yellow => gps data ok, but no fix yet, green/off => all is good, green/yellow => gps good, temperature sensors bad, green/red => had a fix, lost it
[17:51] <DanielRichman> it worked perfectly!
[17:51] Action: DanielRichman is happy
[17:51] <DanielRichman> time for some homework :X

[19:40] <Laurenceb> hi
[19:41] <Laurenceb> what hapened with the balloon?
[19:41] <rjharrison> It opoed
[19:41] <SpeedEvil> nothing yet
[19:41] <rjharrison> poped
[19:41] <SpeedEvil> oops
[19:41] <rjharrison> Oh which one
[19:41] <Laurenceb> last night
[19:41] <Laurenceb> nova13
[19:42] <SpeedEvil> payload not recovered
[19:43] <Laurenceb> :(
[19:44] <Laurenceb> google changed its color scheme

[19:51] <natrium> hrm?
[19:52] <SpeedEvil> notfor me
[20:07] <DanielRichman> Hmm. Circuit seems to be munching 100mA - sound ok?
[20:08] <Laurenceb> whats powered up?
[20:08] <DanielRichman> GPS, three leds, arduino, about 4 Potential dividors, two voltage regulators
[20:09] <DanielRichman> **not arduino, atmega162
[20:09] <Laurenceb> sounds about right
[20:09] <DanielRichman> great
[20:10] <DanielRichman> testing the SMS now
[20:10] <DanielRichman> should work
[20:10] <DanielRichman> all the standalone tests were fine - just testing it integrated into the main app now
[20:10] <Laurenceb> 50ma gps, 15 avr, then the rest for leds ect
[20:10] Action: DanielRichman waits until the 5 minute timeout is reached.
[20:10] <DanielRichman> two leds are kept on, one flashes - it fluctuates between 83mA and 90mA
[20:10] <DanielRichman> ~92mA, even
[20:11] <natrium> SMS PLZ
[20:11] <DanielRichman> natrium, I can't send you a sms :(
[20:11] <natrium> why not?
[20:11] <DanielRichman> crazy international tariff, and the phonenumber is hardcoded
[20:12] <natrium> ok then
[20:12] <DanielRichman> sorry :(
[20:12] <SpeedEvil> DanielRichman: if driving the LEDs at 20mA - they are likely just as visible at 5mA - and it's a fair saving
[20:12] <SpeedEvil> giving you more time on the ground
[20:12] <DanielRichman> SpeedEvil, too much of a pain to change
[20:13] <DanielRichman> besides, how much of a big deal is 20mA?
[20:13] <SpeedEvil> 20mA*2.5 = 50mA
[20:13] <DanielRichman> (currently using a 560R, its a bit more like 11mA)
[20:13] <DanielRichman> saving 6
[20:13] <DanielRichman> => 12mA
[20:13] <SpeedEvil> fair enoguh
[20:13] <DanielRichman> battery I'm testing it is 200mAh
[20:13] <SpeedEvil> Battery liffe on the ground can be unfortunately important though.
[20:14] <DanielRichman> *with
[20:14] <DanielRichman> Not sure how beefy the lithiums are, but should be ok
[20:15] <natrium> DanielRichman, btw, a good idea is to use sms2email
[20:15] <natrium> then you can set up your server to add the positions automatically
[20:16] <natrium> by redirecting all emails to your script
[20:16] <DanielRichman> interesting
[20:16] <natrium> i will show you my script one sec
[20:17] <Laurenceb> I'll show you my scripts if you show me yours

[20:20] <DanielRichman> Hmm. It'll be irrelevant if this thing doesn't actually want to send smses...
[20:20] Action: DanielRichman restrains himself, refuses urge to debug, gets on with h/w
[20:21] <natrium> DanielRichman, http://pastie.org/508886
[20:22] <DanielRichman> Tastey regular expressions :)
[20:22] <natrium> hehe
[20:22] <DanielRichman> regexps are great in PHP
[20:23] <natrium> and then forward your emails to script like "|/path/to/your.php"
[20:23] <DanielRichman> 'cause the language is so slow it's actually quicker to use a regexp than check each char
[20:23] <natrium> you can use C too :P
[20:23] <natrium> or asm!11one
[20:23] <DanielRichman> !!!

[20:23] <DanielRichman> You're toying with dangerous things here
[20:24] <DanielRichman> postfix's ability to forward emails to a pipe is great
[20:25] <natrium> it is
[20:26] <DanielRichman> so simple but ridiculously powerful.
[20:27] <DanielRichman> Yay for linear programming
[20:27] Action: DanielRichman yawns.
[20:30] <DanielRichman> Anyone here used Rhythmbox?
[20:34] <DanielRichman> "Anisa is buying apples... she wants at least 6 apples... she buys `a` apples... Explain why a) a >= 6"
[20:34] <DanielRichman> -.-
[20:34] <DanielRichman> This is meant to be Admaths
[20:37] <Laurenceb> lol
[20:37] <Laurenceb> whats the definition of linear programming?
[20:38] <DanielRichman> Fancy name for a practical applications of lots of inequalities
[20:39] <DanielRichman> for ex: Anna buys a apples, b bananas. Wants atleast 6 apples, 8 bananas. Apples cost 24p, Bananas 20p. Must buy 18 fruit in total. Has max of £4 to spend. Go figure
[20:39] <Laurenceb> so thats solved automatically?
[20:40] <DanielRichman> Oh no it's not "programming"
[20:40] <DanielRichman> no computers involved.
[20:40] <Laurenceb> oh ok
[20:40] <DanielRichman> "You will need graph paper for this question".
[20:40] Action: Laurenceb never came actross this even in a level maths
[20:41] <Laurenceb> its just logical arguments surely
[20:41] <DanielRichman> It's been a bit of a nosedive. Last week Cumulative Binomial Distribution, now this...
[20:41] <KingJ> It's in D1 at A Level
[20:42] <Laurenceb> heh fairdoos
[20:42] <Laurenceb> I never studied it, but it was a few years ago
[20:42] <KingJ> Ah. I sat the D1 exam a few weeks ago
[20:44] <DanielRichman> How'd it go?
[20:44] <KingJ> Not bad, very easy exam
[20:44] <DanielRichman> You doing further maths too?
[20:45] <KingJ> Heh, no way. I stopped at AS, I only did D1 as an extra module this year to replace my (quite bad) M1 module from last year
[20:45] <Laurenceb> good luck
[20:45] <Laurenceb> hehe M1 sounds familiar
[20:46] <KingJ> Mechanics - v=u+at etc
[20:46] <Laurenceb> yeah
[20:52] Action: SpeedEvil drops KingJ from a tall tower, together with a cannonball, while standing at the top with a stopwatch.
[20:52] <DanielRichman> For the convenience of the examinee, assume that he's also in a vacuum
[20:53] <SpeedEvil> Dyson, or Vax?
[20:53] <SpeedEvil> And is it a wet/dry vacuum?
[20:53] <Laurenceb> lol
[20:53] <DanielRichman> It's an 'ideal' vacuum. Didn't I say convenience?
[20:53] <Laurenceb> vax ftw

[22:19] <SpeedEvil> yeah
[22:19] <SpeedEvil> seen those before
[22:19] <SpeedEvil> what for?
[22:44] <Laurenceb> Im a chargin ma lazerz
[22:47] <Laurenceb> for tracking lgg projectiles
[22:49] <Laurenceb> http://wiki.ukhas.org.uk/projects:habe <- new
[22:49] <Laurenceb> who is that?
[22:51] <SpeedEvil> ah
[22:51] <SpeedEvil> 10um sensors are _EXPENSIVE_
[22:51] <SpeedEvil> and not very efficient
[22:51] <Laurenceb> the problem is the projectile moves so fast it smears itself across loads of sensors
[22:51] <SpeedEvil> and need cryocooling
[22:51] <SpeedEvil> IIRC
[22:51] <Laurenceb> *pixels
[22:51] <Laurenceb> on the ccd
[22:52] <SpeedEvil> boresight star-tracker, ....
[22:52] <Laurenceb> I think gun launch is too hard to track
[22:52] Action: Laurenceb failed to fix windows
[22:52] <SpeedEvil> :/
[22:53] <SpeedEvil> lose anything?
[22:53] <Laurenceb> guess I'll have to get an external hdd and back everything up
[22:53] <Laurenceb> then reinstall
[22:53] Action: SpeedEvil has a windows system up for the first time in most of a decade.
[22:53] <SpeedEvil> Bought second hand laptop with it on.
[22:53] <SpeedEvil> Doing battery life tests, then windows goes.
[22:54] <Laurenceb> why have they made the urls a weird green colour on google
[22:54] <Laurenceb> makes my eyes go funny
[22:56] <Laurenceb> I need xp to test my programmer fully
[22:56] <Laurenceb> I'll probably have to borrow someones machine to do it
[22:58] <SpeedEvil> the added tools look iinteresting for google
[22:59] <SpeedEvil> I'd offer - but it's a bit far :)
[22:59] <SpeedEvil> search for 'fish' - then click the 'show options' tab
[23:02] <Laurenceb> neat
