The projects listed here are ones I’ve spent enough time to warrant some documentation. Not everything I piddle with deserves such treatment, so what you will see here is a bit more special than average to me.
A whiteboard plotter is a popular project that has been done may times and in many different ways. Basically, two motors are used to move a marker across the surface of a whiteboard. I plan to start with some simple goals and incrementally add features as I gain a better understanding of the existing mechanism.
