Interesting Higher Powered Joule Thief I just made.
« on: October 24, 2013, 12:30:31 PM »
I took a ferrite out of a CFL and rewound it.  I put 30 or 40 turns around it (same wire it had just less turns) and on top of that I put 4 or 5 turns.  I have a S8050 and a BC337-25 in parallel and this is what happened with a 1.30V battery.

Can you please post a Circuit Diagram, because it's
real hard to tell what's connected to what.


Thank you.

Yeah, this camera takes blurry videos which blows but I do not have the cash to get a better one.

Thank you for posting that clear diagram.


Can you also post a new diagram showing where you insert that
bigger resistor in the YouTube video that makes the LED BRIGHTER.


Thank you.

That should have been very obvious as I slapped it in parallel with the 1k and if you do the math the final resistance would have been .99 ohms.  The big blue resistor was 1 ohm 1%1/2watt where as the 1k was 5% 1/4 watt.

Perfect and it has it listed properly as NPN.  Why a lot of them show it as PNP I have no idea.

Part 2 has much better close ups (I used some reading glasses over my lens, lol) and I am really excited by what I achieved.
