By Andrew Gregory. Posted
This article was originally published as part of HackSpace magazine, which has since been incorporated into Raspberry Pi Official Magazine.
This looks like it shouldn’t work, but it does, and we’ve spent far too long playing with it. The two gears are non-uniformly shaped, but they’re put together so that the widest point of one gear exactly meshes with the smallest point of the other one.
