Old toothbrushes can be used for all sorts of things - cleaning greasy engine parts, scrubbing hard-to-reach toilet nooks, and creating robotic artists. The folks at Evil Mad Science Laboratories discovered a simple DIY robot project. It uses a toothbrush head, a pager motor, and a watch battery. A spin off of the Bristlebot is BrushBot, a project designed by Christian Cerrito, that uses two heads instead of one to vibrate around on a palette of paint blobs.
