Solenoid engine build

I build a solenoid engine that is based on the design of The Pratical Engineer (Emiel Noorlander).

Project page: https://thepracticalengineer.com/blog/diysolenoidengine

Some dimensions

A: Plunger

Material: steel bar
Ø: 6mm

B: Crankshaft

Material: Aluminum strip
Tickness: 2mm

C: flywheel axis

Material: steel bar
Ø: 6mm

 

Little change in the electronic schematic

The design of the schematic by Emiel had a missing resistor between the mosfet Gate and Ground.
The Gate is like a capacitor, when it is loaded the Gate closes, if the current is not unloaded fast enough the Mosfet stays active.

Always add a resistor between the Gate and Ground.

I added that to my build, and informed Emiel about this.

SW2 = Toggle switch
SW2 = Momentum switch
D1 = Diode (min. 3A)
Q1 = Mosfet N-Channel, IRF530N
R1 = Resistor 10K
R2 = Solenoid
