RE: Solar/Joule Theif Setup
I don't have figures, sorry. But I can hook a 9volt battery up to this setup, with 5 or so LED light bulbs, and it always seemed to last about 8 to 10 hours, if that helps. To me, that is pretty good. You will not find this kind of efficiency with power inverters, and I have yet to see it in even bulbs made for 12volts. Laserhacker.com and his YouTube can explain it much better than I. I need to rewrite the diagram, when I was making this, I didn't have others being able to understand it in mind. I will hopefully do this today at some point, and add to the article and reply here. Thank you for your interest!
Thanks. Ill look further. If you do redo your diagram. Pleasepost it. Ike that youve done it with repurposed materisls.
Its still a bit confusing, this is another one I found that I had already made. Between the two, and laserhacker.com or youtube, you should be able to figure it out. Any questions, just ask! :)
It seems I forgot the blocking diode on the transistor, between base and emitter in the diagram. Don't make the same mistake, in real life!
