[00:09] <EI5GTB> ?
[00:10] <EI5GTB> thats an equasion for acceleration|
[00:10] <EI5GTB> ?
[00:10] <EI5GTB> or is it U=..
[00:10] <EI5GTB> hmm
[00:11] <EI5GTB> Laurenceb, I NEED TO KNOW !!
[00:11] <Laurenceb> kinetic energy
[00:12] <EI5GTB> is it??
[00:12] <EI5GTB> hmm..
[00:12] <EI5GTB> AAAH
[00:12] <EI5GTB> U = (At^2)/2
[00:13] <Laurenceb> yes
[00:13] <EI5GTB> :D

[00:39] <Laurenceb> cya
[00:39] <EI5GTB> oh, before i go, know a cheap place to buy a 10 turn pot?
[00:40] <Laurenceb> nowhere ?
[00:40] <Laurenceb> they are expensive
[00:40] <EI5GTB> grr, i have one
[00:40] <EI5GTB> but for an elevation AND azmuthn rotator you need 2 apparently
[00:41] <EI5GTB> unles... think of any other cool ways of measuring elevation?
[00:41] <Laurenceb> would make sense
[00:41] <EI5GTB> inclinometer?
[00:41] <Laurenceb> ooh found it... but with stupid myspace thing
[00:41] <Laurenceb> http://uk.youtube.com/watch?v=wfa8W5oMRoY
[00:42] <Laurenceb> maybe an accel but it would be more expensive... pot is probably the best way to go
[00:42] <EI5GTB> hmm
[00:42] <Laurenceb> thats so old be soo good

[10:26] <jcoxon> indeed :-)
[10:27] <EI5GTB> ok
[10:27] <EI5GTB> :P
[10:29] <EI5GTB> im wondering aout the rotator im builfding.... im measuring the position using a 10 turn pot.... should i putan avr out there that wil encoed the elvation and azmuth and send it back to the controller as an rs-232 signal... or just run wires from the pot into the controller (10m or thereabouts)
[10:30] <jcoxon> hmmm you might want to ask laurence but probably have the avr out there
[10:31] <jcoxon> rs232 will be more resiliant the the distance then the wires from the pot methink
[10:31] <EI5GTB> thats what im beginning to think..
[10:31] <EI5GTB> yea
[10:31] <EI5GTB> that, and i need less wires..
[10:31] <EI5GTB> heck. i could run the whole thing on 3 wires
[10:31] <EI5GTB> well, 4
[10:32] <EI5GTB> crap... 4
[10:32] <EI5GTB> 5
[10:32] <EI5GTB> power(AC) power(dc) signal rx signal tx and gnd
[10:32] <EI5GTB> rather than controlling the relays from in here... have them controlled by the avr outside..
[10:34] <EI5GTB> ill need up down left right
[10:34] <EI5GTB> 4 relay lines
[10:34] <EI5GTB> or it could be as easy to run the 6 wires..

[21:59] <EI5GTB> Laurenceb, what you think: i have to get the position data from the rotator to the controller over 20m of wire
[21:59] <EI5GTB> do i use an avr out on the rotator and send the data digitalluy
[22:00] <EI5GTB> or to i leave it as an alalouge.. voiltage diveider to the conreoller
[22:01] <Laurenceb> oh hi
[22:01] <Laurenceb> sorry was afk
[22:01] <EI5GTB> np, only after asking ;P
[22:01] <Laurenceb> what sort of cable do you have?
[22:01] <Laurenceb> and are you transmiting from the antenna?
[22:02] edmoore (n=edmoore@pomegranate.chu.cam.ac.uk) joined #highaltitude.
[22:03] <Laurenceb> hi edmoore
[22:03] <EI5GTB> just the azmuth and elevation data
[22:03] <EI5GTB> 2 pots
[22:03] <Laurenceb> was reading about you in the times :P
[22:03] <Laurenceb> EI5GTB: what sort of cable are you using for the data?
[22:03] <EI5GTB> do i convert it to a 10bit digit and send it digitally, or leave it as an analoughe varying voltage
[22:03] <EI5GTB> well, ill probably run it all on cat5
[22:04] <Laurenceb> are you tansmitting lots of rf nearby?
[22:05] <EI5GTB> come to think of it... yes
[22:05] <Laurenceb> hmm you'll probably be ok running analogue
[22:05] <Laurenceb> but your main problem may well be sheliding the pots
[22:06] Hiena (n=Hiena@ left irc: "-=Halt! Hammerzeit!=-"
[22:06] <EI5GTB> well, theym will be encased in a solid metal bnox..
[22:06] <Laurenceb> ah ok
[22:06] <Laurenceb> that will be fine then
[22:06] <EI5GTB> im just wondinering... a 5v signal across all that wire..
[22:06] <Laurenceb> you should be ok with analogue on cat5
[22:07] fergusnoble (n=fergusno@fn217.quns.cam.ac.uk) left irc:
[22:07] <Laurenceb> but use some filtering to block high frequency signals
[22:07] <edmoore> yo
[22:08] <EI5GTB> grand job
[22:08] <EI5GTB> hai edmoore
[22:10] <Laurenceb> EI5GTB: use one of the microchip ethernet ICs
[22:10] <Laurenceb> then you can have a web interfece
[22:11] <edmoore> right, time for a beer
[22:11] <EI5GTB> lol, its my first project :P
[22:12] <Laurenceb> how are you controlling the motors?
[22:12] <EI5GTB> relays
[22:13] <Laurenceb> hmm
[22:13] <Laurenceb> do you know how fast it turns?
[22:13] <EI5GTB> roughly..
[22:13] <EI5GTB> y>
[22:15] <Laurenceb> whats the motor voltage?
[22:15] <EI5GTB> 24vac
[22:15] <Laurenceb> sounds hardcore
[22:16] <EI5GTB> hah
[22:16] <EI5GTB> how?
[22:16] <Laurenceb> 24vac
[22:16] <EI5GTB> whats wrong with that?
[22:17] <Laurenceb> I'm just worried it will be a bit of a jerk when the motors turn off
[22:17] <Laurenceb> will the motors run on 12vDC ?
[22:18] <EI5GTB> nope
[22:18] <EI5GTB> how would an ad motor run on dc?
[22:18] <EI5GTB> ac*
[22:18] <Laurenceb> well if it uses universal motors
[22:18] <Laurenceb> they should be ok
[22:18] <Laurenceb> just not sure if you'll get enough torque
[22:19] <Laurenceb> dc will give more torque than ac
[22:19] <Laurenceb> but 12vDC is still less torque than 24Vac
[22:19] <EI5GTB> these are ac motors.... when you hook up dc.. its like a break
[22:20] <EI5GTB> ac motors cant run on dc
[22:20] <Laurenceb> like a break?
[22:21] <Laurenceb> induction motors wont run on DC, but I'd imagine they used universal motors
[22:21] Action: EI5GTB gets the motors
[22:24] <EI5GTB> nope, dc makes em freeze up solid
[22:24] <EI5GTB> just as you would expect from an ac motor
[22:25] <Laurenceb> hmm odd
[22:25] <Laurenceb> probably uses induction motors
[22:25] <EI5GTB> yup
[22:25] <Laurenceb> hang on, how do you reverse it?
[22:25] <EI5GTB> there are 3 leads coming out of them
[22:26] <EI5GTB> gnd forward and revers
[22:27] <akawaka> gearhead on it?
[22:27] <EI5GTB> is there one?
[22:28] <Laurenceb> odd...
[22:28] <Laurenceb> maybe it has seperate coils
[22:28] <EI5GTB> yup
[22:32] <EI5GTB> akawaka, just got the question :P yea
[22:32] <akawaka> using this for a telescope or something?
[22:34] <EI5GTB> http://merklekorff.thomasnet.com/item/ac-gearmotors/rsible-parallel-shaft-ac-sub-fractional-gearmotors/8165?&seo=110
[22:34] <EI5GTB> somthing similar to that
[22:34] <EI5GTB> antennas.. for working sattelites
[22:35] <EI5GTB> and moonbounce and all that
[22:36] <EI5GTB> may pout a telescope on it sometime.. but it probably wouldnt be accurate enough
