What i'm looking for is a hardware kit/device which can do basically what an etch-a-sketch does but can be controlled via a raspberry pi.
That is, it's a flat device which can move an "arm" around a 2d grid:
My idea is to put a magnet on the arm endpoint, then a piece of glass on top, and be able to move around a magnetic "bug" as a cat toy.
Anyone know of such a kit? Or someone willing to build one with motors that could be hooked up to a raspberry pi?
