But I cant figure out what the cap does in this case. My first thought is that it changes the frequency to fit what the transistor can commute. But I maybe wrong.
Phase two: generator.Firs fail: the toys motors cant supply the current I need to light the LED in the Jule thief circuitry I made.
I will mount a 10 uF to the motor.Few months ago, a friend of mine mounted an white led to a PC fan. It lighted.
