I pulled out my old Laser Projector which has 2 Galvo’s to control very high speed mirrors. Previously I had used a USB DAC to control the position of the laser dot to draw shapes. I got to thinking, how cool would it be if I could make my Fez Domino draw instead. The problem I am having is do you guys know of a High Resolution DAC shield or circuit that can be created to go from -5 to +5 volts? Of course even if it was -12 to +12 would work with a resistor.
So… Any ideas?
