I Made A Solenoid Engine!

I built a solenoid engine. Unlike most motors out there that hide how they work, this beauty bears all. A solenoid is a kind of electromagnet. When electricity flows through this coil, a magnetic field pulls the magnet-topped piston inside up. But when the piston reaches the top, a cam on the axle it’s turning cuts off the flow of electricity, and the flywheel's momentum pulls the piston back down.

But once down, the cam disengages, electrical flow resumes, and the piston goes up again. You can see how it turns electrical energy into rotational energy. To make this happen, my team and I got to design a bunch of custom cross axle compatible parts that I had been wanting for a long time: special cams, pistons, arms, wires, a heavy brass flywheel, and of course, the solenoids themselves.

We even made elliptical gears, Nautilus gears, and a Geneva mechanism. If you’d like to build one yourself and add these parts to your arsenal—too bad, so sad, psych! You can buy one! ABS plastic, ooh, and look at those colors! The first 500 people to use code "I love you Michael" will get 10% off.
