Lidmotor | Transistor Solenoid Engine @Lidmotor | Uploaded February 2022 | Updated October 2024, 1 hour ago.
This is a solenoid engine that is triggered using a simple low voltage two transistor circuit. The circuit is an LED blinker that is configured to use the coil in the circuit as the driver for the solenoid engine. As the magnet moves inside the coil it provides a feedback current to the circuit. This feedback is enough to sync the blinker to the solenoid cycle.
