Pill Bottle Electric Motor — 2 Coils
This is my ‘Pill Bottle Electric Motor’ with two coils. The simple one transistor circuit that I am using here to drive the motor is from my ‘Basic Electronic Pulse Motor’
. Basically one coil is the sensor (trigger) coil and one coil is the drive coil. The energy running this motor comes from a 2.7 volt / 5 Farad super capacitor filled with about 2.5 volts.
