RE: Opensource CDI ignition
couple of questions JMJ, I made the circuit last night but it does not work quite right. On the far right of your schematic there is a resistor and capcitor (C6 and R1) now it says on the diagram to use 4.7uF, but in the parts list it says 4.7nF. I'm just wondering if this is my problem. It makes enormous sparks, but the circuit free runs at about 1Hz, it sits there happily sparking to itself but I'm getting over 600v from the diode bridge[:-]
PS, your toroid pics, is that really 0.1 wire for the 450 turns, it looks a bit thicker? I gave up on 0.1 as my fingers are too big to wind it so used 0.2.
Cheers,
Rich
