[00:40] nowhere ? [00:40] they are expensive [00:40] grr, i have one [00:40] but for an elevation AND azmuthn rotator you need 2 apparently [00:41] unles... think of any other cool ways of measuring elevation? [00:41] would make sense [00:41] inclinometer? [00:41] ooh found it... but with stupid myspace thing [00:41] http://uk.youtube.com/watch?v=wfa8W5oMRoY [00:42] maybe an accel but it would be more expensive... pot is probably the best way to go [00:42] hmm [00:42] thats so old be soo good [00:42] *but [00:42] haha [00:42] CHAV!!

[10:26] indeed :-) [10:27] ok [10:27] :P [10:29] 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] hmmm you might want to ask laurence but probably have the avr out there [10:31] rs232 will be more resiliant the the distance then the wires from the pot methink [10:31] thats what im beginning to think.. [10:31] yea [10:31] that, and i need less wires.. [10:31] heck. i could run the whole thing on 3 wires [10:31] well, 4 [10:32] crap... 4 [10:32] 5 [10:32] power(AC) power(dc) signal rx signal tx and gnd [10:32] rather than controlling the relays from in here... have them controlled by the avr outside.. [10:34] ill need up down left right [10:34] 4 relay lines [10:34] or it could be as easy to run the 6 wires..

[22:03] do i convert it to a 10bit digit and send it digitally, or leave it as an analoughe varying voltage [22:03] well, ill probably run it all on cat5 [22:04] are you tansmitting lots of rf nearby? [22:05] come to think of it... yes [22:05] hmm you'll probably be ok running analogue [22:05] but your main problem may well be sheliding the pots [22:06] Hiena (n=Hiena@81.93.195.181.datatrans.hu) left irc: "-=Halt!

[22:06] you should be ok with analogue on cat5 [22:07] fergusnoble (n=fergusno@fn217.quns.cam.ac.uk) left irc: [22:07] but use some filtering to block high frequency signals [22:07] yo [22:08] grand job [22:08] hai edmoore [22:10] EI5GTB: use one of the microchip ethernet ICs [22:10] then you can have a web interfece [22:11] right, time for a beer [22:11] lol, its my first project :P [22:12] how are you controlling the motors? [22:12] relays [22:13] hmm [22:13] do you know how fast it turns? [22:13] roughly.. [22:13] y> [22:15] whats the motor voltage? [22:15] 24vac [22:15] sounds hardcore [22:16] hah [22:16] how? [22:16] 24vac [22:16] whats wrong with that? [22:17] I'm just worried it will be a bit of a jerk when the motors turn off [22:17] will the motors run on 12vDC ? [22:18] nope [22:18] how would an ad motor run on dc? [22:18] ac* [22:18] well if it uses universal motors [22:18] they should be ok [22:18] just not sure if you'll get enough torque [22:19] dc will give more torque than ac [22:19] but 12vDC is still less torque than 24Vac [22:19] these are ac motors.... when you hook up dc.. its like a break [22:20] ac motors cant run on dc [22:20] like a break? [22:21] induction motors wont run on DC, but I'd imagine they used universal motors [22:21] Action: EI5GTB gets the motors [22:24] nope, dc makes em freeze up solid [22:24] just as you would expect from an ac motor [22:25] hmm odd [22:25] probably uses induction motors [22:25] yup [22:25] hang on, how do you reverse it? [22:25] there are 3 leads coming out of them [22:26] gnd forward and revers [22:27] gearhead on it? [22:27] is there one? [22:28] odd... [22:28] maybe it has seperate coils [22:28] yup [22:32] akawaka, just got the question :P yea [22:32] using this for a telescope or something?
