Do you like spare time DIYs and also spoiling your toothbrush for fun? Then I have a perfect idea for you, that too with more fun than thought. Follow the procedure and end up with a vibrating robot of your own. Not a difficult task, but just the effort to install a battery, and a pager motor on the head of a toothbrush, which can be controlled by a single vibrating (eccentric) motor. Don’t think I am trying to play with your teeth. Check out the video for your satisfaction.
If you are convinced then crack a cheap pager for vibrating motor, which will be attached on with the foam tape over the bristle head. The motor usually runs on any common voltage between 1-9 V. You can try either alkaline or lithium coin cell, and even devoid your watch for that. Solder the short copper wire that leads to the motor terminals and enjoy your own invention that is unique, at least when so much of spoiling work is involved.
