Hello! My name is Eugene So. I am a Master’s student at New Jersey Institute of Technology (NJIT) majoring in Electrical Engineering. This website describes how to build your own linear actuator or motor using a pair of solenoid valves and an Arduino microcontroller. The linear actuator I am describing was built at NJIT in 1994 by a Master’s student named Alex Rokhvarg under the direction of Dr. Bernard Friedland. My Master’s project was to retrofit the controller for this apparatus. I used the Adafruit Metro M4 as the new controller. Here is a video demonstrating the linear actuator.
