How To make the Joule Thief
In the comments one of my fans''Testas 3339" want to build the great
joule thief circuit so i made it.Also I know that for someone is hard to get the parts so I found way that from old cfl bulb you can salvage the parts and make simple joule thief.
The parts you need to salvage: transitor 13001 or 2n3904,1k ohm resistor,white led,ferrite ring and little transformer for copper wire.
