Here is the driver and its schematic. -THE SCHEMATIC WAS UPDATED- http://www.volny.cz/jmartis/qrv4_en_f... If you have any questions, feel free to ask in the comment section or by personal message. Note: Lately I have fried a lot of flybacks with this driver, so when testing start with more primary turns, something like 14, then if you dare you can go lower.
