They were made by Symbol Tech and are usually labelled as servos or some such. There must be a million of those things lying around, you can always find them on ebay.

I'd use a small value as you don't want to filter out the high-end too much. With, your beams should look slightly sharper as the mirror won't wiggle with the PWM output. but I got decent results with and without. You really ought to add a signal-levelling cap between GND and INV+ pins, as close to the chip as you can get it (soldered piggyback would be my preference). overkill as I'm not using 3 of the op-amps)Īnd hook it up in voltage following mode: Use any single-supply op-amp (I used the LM324 from rat shack as I had it lying around. LINK: Laser X-Y-Axis control - Arduino Forum ![]() I found this online - very cheap way to make a controller. I just need a way I can write computer code to control about 3 or 5 +/-5VDC ILDA pins. ![]() I am a programmer and just want to code some simple cirlces, squares, etc using an Arduino Uno USB board. I have 2 new RGB projectors with galvos and ILDA DB-25 port. Hello, it's been a while since I've posted.
