Good you've got it working Rowland
It's a nice simple looking design, something I could probably make
Does it have a potentiometer or something so you can adjust the output? I built a PWM the other day from a Jaycar kit and it was working ok, but now when I turn the nob nothing changes
must have killed it.
Electronics is not something I've taught myself much about, so if I took your diagram into Jaycar or someplace, would they be able to get the parts I need?
Cheers
