[00:00] <natrium42> EI5GTB, actually, it's probably a good thing
[00:00] <natrium42> stay away from 4chan
[00:00] <EI5GTB> ...
[00:00] <EI5GTB> on the other hand: http://paulsnet.org/lcd/b.JPG
[00:00] <EI5GTB> :D
[00:00] <EI5GTB> ktnx
[00:02] Action: EI5GTB is getting there, Laurenceb ^
[00:05] <Laurenceb> cool, thats one big lcd
[00:05] <EI5GTB> yea,. its pretty sweet
[00:05] <Laurenceb> elevation is at vcc
[00:05] <EI5GTB> yea, its just the way i had the pots set
[00:05] <EI5GTB> as i rise the elevation pot, the other goes up a bit, im trying to figurte out why..
[00:06] <Laurenceb> how much?
[00:06] <EI5GTB> about 30
[00:06] <EI5GTB> over the space of 1024 on the other
[00:07] <Laurenceb> hmm doesnt sound quite right
[00:07] <Laurenceb> how are you driving the pots?
[00:07] <EI5GTB> look at the schematic.jpg in that /lcd/ folder
[00:08] <Laurenceb> hmm
[00:08] <Laurenceb> you dont need to tie Vref to Vcc
[00:09] <Laurenceb> it will be done internally if you configure the ADC to use Vcc
[00:09] <EI5GTB> oh, i se
[00:11] <Laurenceb> http://paulsnet.org/lcd/DSC_4375.JPG
[00:11] <Laurenceb> lol
[00:13] <EI5GTB> haah
[00:13] <EI5GTB> good times
[00:17] <Laurenceb> http://pastebin.com/m32a19ad7
[00:17] <Laurenceb> ^ thats my new nav code
[00:18] natrium42 (n=alexei@CPE000625d867e2-CM0014045885be.cpe.net.cable.rogers.com) got netsplit.
[00:18] Tiger^ (i=tygrys@moo.pl) got netsplit.
[00:18] <EI5GTB> cool
[00:18] <EI5GTB> looks neat
[00:19] <Laurenceb> basically it tries to take into account the drift from wind in the atmosphere below the present altitude
[00:19] natrium42 (n=alexei@CPE000625d867e2-CM0014045885be.cpe.net.cable.rogers.com) returned to #highaltitude.
[00:19] Tiger^ (i=tygrys@moo.pl) returned to #highaltitude.
[00:25] <EI5GTB> heh
[00:32] <Laurenceb> its soo confusing..
[00:32] <EI5GTB> i didnt even try to understand it :P
[00:33] <natrium42> but you got his drift
[00:34] <EI5GTB> yea
[00:34] <EI5GTB> lol
[00:34] <Laurenceb> hehe
[00:34] <EI5GTB> i see what you did there
[00:34] <Laurenceb> Target = atan2((targeteast - Gps.longitude)*cos(targetnorth) - descent_drift_e,targetnorth - Gps.latitude - descent_drift_n);
[00:34] <Laurenceb> is what confuses me
[00:35] <EI5GTB> AAARGH
[00:35] <EI5GTB> *head explode-*
[00:35] <Laurenceb> you have to acount for longitude lines geting closer together
[00:35] <Laurenceb> ;P
[00:35] <EI5GTB> lolwut?
[00:35] <EI5GTB> heres my problem:
[00:36] <Laurenceb> when you are near the poles, 1 degree of longitude isnt as fart
[00:36] <EI5GTB> fart
[00:36] <Laurenceb> erm *far
[00:37] <EI5GTB> ok, so i have a value, varying from 0 to 1024, and i need a function to work out... ok, the user tells me its pointing north, and lets say the value ie 245, and they tell my thayre at south, and the value is 600
[00:37] <EI5GTB> i need to know what compass degrees they are at when the value is 120
[00:37] <EI5GTB> and 900
[00:37] <EI5GTB> etc..
[00:39] <Laurenceb> ok, so (value-245)*180/(600-245)
[00:40] <EI5GTB> i see..
[00:40] <EI5GTB> and i now need to put my rotator at 146degrees, what does the adc value need to read/
[00:41] <Laurenceb> y=(x-245)*180/(600-245)
[00:41] <Laurenceb> invert the function
[00:41] <Laurenceb> (600-245)*y/180=x-245
[00:42] <EI5GTB> hmm , isee
[00:42] <Laurenceb> ((600-245)*y/180)+245=x
[00:42] <EI5GTB> hmm, spose thats the only way of doing it, i was hoping i wouldnt have to do complex equasions a few times a second
[00:42] <EI5GTB> ah, ill just write a few functions
[00:42] <Laurenceb> its no problem
[00:43] <Laurenceb> that will run in < 1ms
[00:43] <EI5GTB> THATS JUST NOT FAST ENOUGH
[00:43] <EI5GTB> !!!
[00:45] <Laurenceb> http://uk.youtube.com/watch?v=F7bKe_Zgk4o
[00:45] <Laurenceb> you could remake that video
[00:46] <EI5GTB> now theres a song..

[00:51] <EI5GTB> ITS A MUST LISTEN
[00:51] <EI5GTB> nsfw!
[00:52] <EI5GTB> "grab your d**k and double click"
[00:52] <EI5GTB> LOL
[00:54] <Laurenceb> sooo old
[00:55] <EI5GTB> lol
[00:55] <EI5GTB> i only just heard it..
[00:55] <Laurenceb> http://www.spacex.com/updates.php
[00:57] <EI5GTB> nice
[00:57] <EI5GTB> what is it
[00:57] <EI5GTB> ?
[00:58] <EI5GTB> expensive?
[00:58] <Laurenceb> erm a rocket?
[00:58] <EI5GTB> heh
[00:58] <EI5GTB> but...
[00:58] <EI5GTB> nevermind
[00:58] <natrium42> lol.
[01:02] <Laurenceb> its a space rocket kiddies
[01:03] <EI5GTB> ORLY
[01:03] <EI5GTB> im just starting the design of my menu system for the rotator

[01:33] <EI5GTB> its 1:30 am on a saturday morning
[01:34] <EI5GTB> normal people arent penciling in the structure of an appliaction
[01:34] <EI5GTB> im away to bed :P
[01:34] <EI5GTB> night
[01:38] <natrium42> already?
[01:38] <natrium42> nite then...
[01:38] <EI5GTB> yea, im getting pissed off cos i realised how difficult it is to design an embedded system
[01:38] <EI5GTB> just... how things are layed out
[01:39] <EI5GTB> hmm, bed
[01:39] <EI5GTB> nighrt
[01:43] <Laurenceb> you mean code wiswe?
