I'm interested in building a rotating POV (persistence of vision) with an arduino. I have a quick question about the motorized part of it. (The motor will be seperately powered) I have a hobby motor, and a few motors from portable tape players (about the size of a hobby motor) in hand, but I don't know exactly if they will rotate fast enough for the POV to work. I'm planning on mounting the led's and the arduino to some light metal if I can find some around. Does anyone have any tips or suggestions? Do I need to purchase a better motor?
Thanks :) -duemilanove
