This is an experimental solenoid engine with my own hand wound coil. The coil is wound on a Delrin form with a .45" center and 1" OD. It has about 200 feet of #24 magnet wire, 95 turns per layer and a total of about 1100 turns. The "Piston" is 5/16" diameter taken from commercial solenoid. The stroke of the engine is about 5/8" and the flywheel is 3" OD The microswitch is rated at 10 amps at 120 volts.

Grasshopper Beam Engine constructed to study the geometry that produces the parallel motion of the piston rod. In this model the power is provided by a 12 volt solenoid and the "valve gear" is a micro switch operated by a cam.

Here’s a solenoid motor you can build from a VCR head and some commoncomponents. It uses an LED and a light sensor, paired with an LM311 comparator to manage the switching of the motor. As the head turns, the LED shines on the sensor through a hole and triggers a TIP120 transistor to turn on the motor during the power stroke. Once the beam of light is broken, the transistor turns off the motor and the momentum carries it through its revolution until the next power stroke is activated.
