Description
Plateaus for mounting round 20 and 25 mm laser mirrors to a small DC motor.
The mirror is angled at 4 degrees, so the mirror is wobbling. By beaming a laser across two rotating mirrors, and playing with the speed ratios, exciting hypocycloids can be projected.
Shaft of the 25mm model might be fixed to 4mm fischertechnik axle. The 20mm model can be slided over the worm-axle of a fischertechnik Mini- or S-Motor.
