Inverted Joule Thief Part 2
This is part 2 of my ‘Inverted Joule Thief ‘project. I added 200 more turns to the secondary winding of the coil to increase the output of the device. The end result was that the circuit produced more light and had better charging. A second transistor and heavy duty resistors were added to help with deal with the heat produced. A regular flourescent tube was used instead of a modified CFL.
