You should post it, we would love to see it.


Hey all:

I wonder if we can light a 9000 lumen (yes 9000) led chip?

You know we are going to have to try it right?

Nice.  What was the voltage on that 1F supercap? 2.7 volts?  You can light that bulb very nicely on only 1.5 volts (or less) using the Jeanna Circuit or a modified flash circuit.  It will be on all of the time, and bright too.  Very good job for that small toroid though.  Well done.

John:

Here is the Jeanna Circuit.  The flash circuits are very board specific depending on if you have a Kodak, Fuji AA, Fuji AAA, or no name surplus board.  If you find or have a board, I will be happy to try to tell you how to modify it.
