    Anatomy of a flyback transformer

    To measure HV you can buy a HV probe, or I make a voltage divider, then read the v drop across, the or a resistor, use the formula            E                          ' ------------- I  x  R It seems to me, you should probally do a lot of reading, I do not know how much info is on this...

    Anatomy of a flyback transformer

    I think a IRF460 is what worked best for me, it is overkill. with this board using a 7812, you wioo only have 12 volts to play, with that I had to wind my own primary. You can use a bunch of diffrent values, from what I have read 15k to 20khz works best, but I have not played too much with the...

    Anatomy of a flyback transformer

    You have it, I did not use the orange and white wires, but they may be taps off the secondary winding. also the HV ground or return, it is one of the cut pins I marked. I got much better results winding my own primary winding, I wound 4 or 5 turns of 16 gauge  magnet wire around the ferrite...

    Anatomy of a flyback transformer

    Hello, I too got a couple of these flybacks.they are not great as far as I can tell. I have tried to get a pin out from them with no luck, (you got these on ebay, right from K&plans) I found the return for the secondary (the big red wires other side or ground for the HV) unfortunately it is...
