I want to spend as little cash as possible and get some sort of scanner that I can control with a microcontroller or computer. I guess my plan right now is to use my red labbie, and a green module combined with a microcontroller/audio source, and a transistor to each module. I have a couple dichros so I could make an RGY laser. However, the problem comes with the actual scanning part. I dissected a couple of old CD drives our IT guy gave me and got those little focusing things that tilt to either side, I'm pretty sure using 2 digital pins on an arduino with PWM and flipping the polarity of each should let me control the tilty thing pretty easily, and give me some sort of rudimentary XY setup with 2 of them. However, I don't want to go through all this annoyance and trouble if I can just spend a few bucks and get some really crappy galvos or a used setup or something. Plus, I still have to get the mirrors. So should I go ahead and try to make this, or is there some other way that I can get a rudimentary scanner cheaply? (No need to draw pictures on the wall or anything with the laser).
Thanks,
