Hello,
I have constructed a Joule Thief device following the instructions at:
YouTube - Make a Joule Thief
**broken link removed**
It did not work. After checking the wiring and the components I realized I was sold a 2N3906 transistor instead of the 2N3904 I had asked for.
Some google searching told me the transistor I have is PNP and the one in the Joule Thief diagrams is NPN. I am not an electronics expert, but I can see one of the diodes is reversed in the PNP type, I guess that's why it doesn't work.
Now I could (and probably will) buy the correct transistor, but I was wondering if there is a way to make it work with the 2N3906 transistor, maybe with a different wiring.
Thanks in advance!
