Door Alarm Coil pulse motor
This is a homemade electronic pulse motor that uses a bifilar inductor found in a cheap door alarm. The circuit that I am using is a very old ‘electric clock’ circuit used in the ATO Clock. I added a 10 K variable resistor to the base feed and an LED indicator light. The energy storage component is a 2.7v 5 F super capacitor charged to 1.5 volts.
