Two simple circuits are together in this schematic. The one below conisting of a inductor , a mosfet, a diot, a led and a capacitor is the boost convertor. I added a flip flop to give pulses to mosfet. It should operate at 90 hz which is I think enough to boost the voltage. I guess it requires more adjustment to give it a really good high voltage but I cant do this here as I continually get the message " CAN NOT FIND A SOLUTION".
