What

For some time I have wanted to aim a laser with good precision across a room. Long time ago I did this with servo motors, Worked fine excpt for the good precision. I thought that steppers might do better. The problem is that steppers move ( typically ) over a degree per step. Gearing the motor down decreases the speed, but improves the precision. These can be cheap ( Amazon.com : Longruner 5x Geared Stepper Motor 28byj 48 Uln2003 5v Stepper Motor Uln2003 Driver Board for arduino LK67 : Camera & Photo ) With these in hand and a 3D printed mount ( *Bare Bones 28BYJ-48 Gimbal. by mmontee - Thingiverse ) for them I went forward with the software.
