We love when gearheads and hardcore DIY experts show off their talents, and what we’ve got here is a perfect example of that. In the above video, engine builder and YouTuber David Robert gives a little demonstration of his homemade V-12 solenoid engine, and it really is a sight to behold.

The overall design is configured to look like an internal combustion engine, but the actual mechanics are very different. Using magnetic solenoids to drive the crankshaft, this engine can run as either four or two stroke and can alternate between the two.

Built from 140 found parts, this engine was built for fun out of scrap materials after Robert successfully built a similar single cylinder prototype. It doesn’t crank out much torque, but it sure is a cool little novelty that any gearhead can enjoy!

If you want to get a more detailed look at the technical details of Robert’s project, you can check them out below.

  • Type: 60 degree V12 electric piston engine
  • Maximum RPM: 3,200 RPM
  • Input voltage: 24 volts dc
  • Speed controller: Mechanical PWM
  • Cylinder bore diameter: 8mm
  • Piston stroke length: 10mm
  • Total theoretical displacement: 6cc
  • Firing order: 1, 12, 5, 8, 3, 10, 6, 7, 2, 11, 4, 9 (Same as old type Ferrari)
  • Main bearing size: 4x9x4 mm (684zz)
  • Big end bearing size: 4x9x4 mm (684zz)
  • Flywheel mass: 900g
  • Switching transistors: 2N3055
  • Solenoid model: SOLEN 121E16530 (with built in flyback diode)
  • Total mass of engine: 6kg approximately
  • Exhaust emissions: zero

As Robert points out in the video’s description, he didn’t just jump right into building a V12 solenoid engine. Before embarking on his V12 project, he built five other solenoid engines, including a steam engine-style solenoid engine and a V8 solenoid engine.

He really outdid himself with the V12 model, though!
