    flyback transformer driver

    your luckey ive never had 10 or 15 kv caps as the local electronics stores dont have them of that rateing , so with some of my ignition coil drivers i use a high voltage trippler, to tripple the output hv from the ignittion coil, some hv tripplers are larger and black in colour if youve see all...

    flyback transformer driver

    go to page 3 in the high voltage stuff section look at flyback driver schematic. if you want to measure the high voltage output on a digital multimeter look at high voltage resistor devider. and if you dont have a flyback transformer with a biult in high voltage trippler  to give bigger longer...

    flyback transformer driver

    look carefully through the high voltage section  youll find flyback driver circuit  it uses a 25k pot and 10k potentiometer or variable resistor, dont worry if you cant find trimpots as i dont use them i use potentiometer s, the flyback driver circuit i used was oriiginally  used in the vortex...

    Need some electronic add-on ideas for my new project (Stirling engine)

    hello daza long time no hear. i to have the details to biuld the stirling engine to , you can use the counters from out of a cassette player i think as youll only need to modify it to turn a small wheel and run a band from it to the cassette counter , thats one idea , as for turning a generator...

    Capicitor Help

    :) it looks abit like an inductor to me as the grey looking cover is like the ones on my inductors. hold a magnet to it and if it sticks, then you have an iron core inside that, and it would be an inductor , if it dosent stick it would be a capacitor , but unusual one for what i can see
