I'm finally moving forward on a project I've been contemplating and working on more-off-than-on for about five years now. I'm planning on using the Bottango Solar Board and software to drive it.

Pan and tilt eyes, jaw, rotate and tilt head, plus one servo for each arm for simple gesturing. Ten servos, which is all the board can handle without adding another board. Skull will be 3D printed, skeleton is store bought. The head rotation is via a turntable bearing on top of a universal joint for tilting. The two plates connected to the rod and universal joint, and for mounting the bearing are aluminum.

I'll have him tell bad dad jokes, halloween puns, and one-liners. He'll stand on a wooden platform, dressed in a ragged suit. I like this idea better than "spooky", threatening comments. I'd much rather entertain with jokes.

I'm happy to hear any suggestions or warnings about such a project. My experience with this sort of thing is limited to an old RC glider I built years ago.
