Can I make a joule thief with Pnp transistor? Answered

I  was making my joule thief recently and I could not get success. I found out that I have Pnp transistors and that's why I am wiring them wrong. Can anyone provide me with a schematic to make it with Pnp transistor?  Thanks for your help!!

Yes, I have done so. Since it is a single transistor design, All you have to do is built it like normal, just reverse the polarity!

If i know is correct. Just place the PNP in place of the NPN as normal and then all you have to do is reverse the battery polarity. Afterall a PNP is practically a reversed NPN!
