Has anyone here managed to figure out how to make the faceplate on an Iron Man helmet, open and close automatically? I know someone called Masterle has done it, but I've been banging my head against a wall trying to figure it out. Worm drives, Servos, Motors. But nothing seems to be small enough to fit into the space with my head in the way! I know how to do it manually but I want to show off a bit.
Any help or clues as to how, would be much apprieciated.
