Chances are, everyone here has seen those nifty doodads that, when spun, display an image from a couple of pulsed LEDs on the end.
I was wondering, though: Using a laser pointer placed on a spinning shaft, how hard would it be to achieve a similar effect? I would assome that, by pulsing the laser at the exact same point in the rotation, it could be made so as to appear as to maintain a stationary beam. The spinning laser could then produce multiple beams by pulsing at the appropriate intervals.
Any thoughts?
(I intend to make this thing out of a diode laser from a cheap laser pointer, and a cheap motor rom a dremel knock-off, and perhaps the optical rotation sensor from a cheap ball-mouse. Nothing fancy or expensive.)
