I got the idea from scopeboy's website
on his flyback driver
section, but the schematic was quite complex and buying four MOSFET's is a little too expensive for me...
So I simplified the design to using one MOSFET.
I get a lot of complainants of this project is not working very well or at all. This new design WORKs, however, for most people it may not work. This is due to the MOSFET (and some other components) is poor quality.
I just recently found out that manufacture who makes the components sell the best quality ones to other manufactures and sell the poorer quality ones to the whole sellers and retailers. For this project, the best grade MOSFET's is critical, and it can only be gotten by salvaging old electronic devices, unless you are willing to pay for thousands of components for the manufacture... :-)
