Don’t throw away your old toothbrushes. With a small vibration motor you can use them as an exciting toy to play hockey. Just push them and they run away at high speed. The switch is a simple connector. An SCAD file is included in case you need to change the motor diameter.
All types of brushes can be used.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
