Joule Thief

[gadgetmall]

@ Gadgetmall:

Thank you.  I have not thrown an AA battery away since we all started this.  I keep thinking....maybe it is not really really dead yet.  I have a baggie full of them and some of my friends are saving theirs for me as well.  Might as well really kill them before sending them to the landfill.

I recharge them with a bedini also until they leak . maybe 10 times .. when they leak it dries to a white power all over the 8 aa holder . i just wash it in baking soda and water and it clean again . . The cool thing is ones that dont leak . They are enigizers and duracell / the off brands and rayovac Leak after 10 or so recharges . BUT you see they are still usable up to this point ..

I wanted to see how many 1.2v AA batterys it would take to light the CFL up.
One just wasn't quite enought to light it up.
So I tried two and it light up.
Its not nearly as bright as it was off 12v but its not bad for just two batterys.

Heres a video of it lighting off two 1.2v batterys.

@ Wer:

First, welcome to our group!  Next, that is a great price for something like that.  I purchased 3 solar cells a few weeks ago and have not had the time to work with them.  Thank you for posting this, and again, welcome to our band of merry experimenters here.
