can i make a magnetic POV?
my idea is to make a small box, with a moving POV in it, wich moves only from the left to the right, and back.
this uses a small POV system, 2 elektromagnets, some way to make the leds go in the right direction, some iron/steel, and something to controll the magnets.
i wanted to know, is this possible, and if so, what magnets, controlling device do i need and how do i make the leds go in the right direction. i've considered the tracks from a CD player, but i think theres a cheaper/better way to acieve this...
if i get enough info to make one, il make a full instructable of it :)
