I'm looking for a small spinning polygon mirror with motor. It can't be very big, a few 3" for the whole assembly maybe?
Looking at mounting it in a large underwater flashlight housing and then doing PWM of one or two diodes against it to draw patterned line (AtMega code prob.)
Laser printers seem to be one source of these but the assemblies I'm seeing are fairly large. Also, I plan to run this on batteries (probably lipo/lion + buck-boost to 5vdc get me where I need to drive diode drivers.)
Thoughts?
