How to Make a Toothbrush Timer Out of a Pair of Novelty Chattering Teeth

Make Magazine explains how to make a toothbrush timer out of a pair of chattering teeth. The project, created by Steve Hoefer, uses a timer chip and modified servomotor to chatter the novelty teeth for the suggested amount of time necessary to brush teeth properly.

Using a 555 timer chip, a modified servomotor, and chattering novelty teeth, get your dentist-recommended brush time every time, with the Toothy Toothbrush Timer.
