How to remove the offset weight from the shaft of the electric motor inside the DR Fresh Velocity Turbo Power Battery Powered Toothbrush.
I use these vibrating toothbrushes as the power unit for several of my projects. They are cheap as they come from Poundland and 99p Stores. I expect they may appear with different names and packaging in other shops.
They are a complete package including an on/off switch, a battery, and an electric motor with an offset weight. This makes them ideal for a vibrating bristle bug or any other item that relies on vibration to provide the motion.
On my electric toy car I didn't need the vibration effect so it was necessary to remove the weight. I showed how to do this on that video but then I thought it might be handy to do a stand alone helpfile on the subject and here it it.
Here are my other projects using this power source.

If you have the smaller electric motors from the more expensive toothbrushes then you may need this helpfile.
