Beautiful peace of machinery !!! I really like how much effort you put in to mechanical, wiper, like commutator. Don't even wont to think about how much time it took you to make a V12. My question would be, how much more rpms can you achieve on, say v12, if you will upgrade it to, say rotary optical encoder? Its just a disk on crankshaft, with holes for optical sensors, which in turn will drive your NPN transistor. And instead BJTs maybe Mosfets would do better, they operate faster,have lower voltage drop, you would only need to add free-wheeling diod's. Would love to build one in future, but now I'm on my electric project. see videos :)

What's the purpose of the diode? Wouldn't the current just go back to positive through the solenoid no problem?
@davidrobert20079 жыл бұрын
The diode in this application is called a flyback / freewheel diode, it's purpose is to allow the back emf (high voltage spike caused by the collapse of the magnetic field in the solenoid coil when it is disconnected from the circuit) to dissipate through the resistance of the solenoid coil. Without this diode the back emf would destroy the 2n3055 transistor pretty quickly.

Oh okay I get it. And the copper wire, I see that it rides the wheel, but where is the electrical path going? It makes sense on paper, but I'm trying to see it on the machine itself.
@davidrobert20079 жыл бұрын
The copper wire that rides the wheel goes to the base of the transistor (via a series resistor) and the transistor (being used as a switch here) switches the solenoid coil on. This arrangement allows the rotary speed control switch to use a very low voltage to avoid sparking and burning of the moving contacts.

A lot of the build process involves finding random "odds and ends" and cutting / bending things to fit - there is no set process, but what I did was to get ideas from other people's engine builds, plus a ton of research on google. For instance the crankshaft on this engine was the armature out of an old electric motor (maybe from a fridge - not sure as my friend donated it to me), the pwm wheel is made out of an aluminium airline fitting (cut down) with a bit of copper water pipe pressed onto it, and electrical tape to insulate part of the copper area. There is a lot of "Heath Robinson" type engineering involved, I recommend to start small and work your way up, and good luck.

@davidrobert20079 жыл бұрын
Hey thanks! the solenoid will only pull but not push, and it is switched on when the movable wire contacts the bare copper section of the rotary switch / commutator. When the movable wire contacts the insulated section of the commutator the solenoid switches off and the flywheel momentum turns the crankshaft, pulling the piston out for the next power stroke. I hope that helps!

davidrobert2007 That is a very clever way of doing it, similar as to how the windings of a motor receive power from the brushes as the commutator rotates right?

I love this electro mechanical devise! do you think using a laminate piston of high carbon steel would reduce magnetic lag and make a difference in speed and or power? I wonder how much more power your v12 model has than this one. I am big into apposed engine types used in aviation such as the 0-290 like what's in an old porch or VW Bug. I also like the balance of these engines naturally balancing themselves out firing in complete opposite ways at the same time. I've been seeing stuff on super electromagnets as well using paper thin sheets of cooper and insulator stacked up in a way creating crazy amounts of lines of flux and all that. I wonder can this concept be used with your circuit solenoid engine. do you imply the joule thief circuit in your circuit? I know a lot more about gas engines than I do electric but I was looking at your diagram and wondering if that transistor your using was making your circuit like a joule thief circuit or school girl circuit what have you? I don't want to sound crazy I've just got a lot of ideas from what your doing. I feel like this electro mechanical cam shaft you made is brilliant, and I want to know if you think this engine can be made to pull more than it needs.
