#2525: WhizzDrive

Today’s invention is one I made earlier.

It offers a way to use a common electric toothbrush, with an oscillatory head, as a source of unidirectional drive.

This might be used as eg a tooth polisher or as a low-torque screwdriver.

As an added bonus, this was achieved using the very low-cost internal ratchet mechanism of the ubiquitous clickpen.
