Magnetic stirrer 120mm fan

A basic magnetic stirrer based on a 120mm fan.

Features a on/off switch and a pot for speed adjustment. While I do not normally recommend controlling the speed of a motor with a pot, in this case the motor uses very little amperage. A video of it in action can be found here https://youtu.be/qgcFWakViK8
