Summary

Overview
This is a simple hack that allows users to activate an electric toothbrush without having to press the on/off button. This modification adds a reed switch to the main board of the toothbrush so it can be activated through close contact with a magnet embedded in a 3D printed ring. It’s suitable for users with limited finger dexterity or one handed users.

Usage
Superglue the magnet into the hole on the 3D printed ring. Turn the toothbrush on and off by placing the magnet ring on the outside of where the reed switch is.
