I had an old broken laserdisk player that needed throwing. So, amongst the parts I've salvaged a nice little set of X/Y positioning mirrors. I'm using a 2mw red diode from a cheap laser leveller as the source, and Audacity to make some square waves.
Now all I need is money for an Arduino kit, couple of op-amps and associated bits.
make lots
