[xee2]

@ gadgetmall,

I am no longer following this thread, but I happened to notice your post and was surprised. I am glade to see you are still posting. To those who do not know, Gadgetmall did a lot of work finding ways to lower the power consumption of Joule thief circuit.

To Artic Knight,...I would like to hear a little more about how frequency affects other frequencies,..........I've done lots of reading but have a hard time wrapping my mind around it,......but believe its' very significant,...Tesla seemed quite interested in it...........shylo

xee2 glad to see you brother . I got that feeling to touch base before the .. well . u know .  For the new guys at the tail end this is an unfinished project i was doing . its basically a big ring some wire a transistor pulled from a broken PC powersupply along with the adjustable pot . this was based on Jeannas Light  and she has Done most of the hard research and documented the numbers here mainly .. As you see its got a 110 plug on it and runs from a C cell for about three weeks solid . This one is turned down all the way cause i remember blowing out  some strings of white leds with it . My brother says it makes him sick and it hurts his head from it being so loud . I cannot hear it  and i am sick already soo..Now is a good time to stock up on warm white leds . as you see the 20 at the end are extremely bright white just like the filament bulbs . these are amazing  power savers light source with plenty of lumen s 

Ps. Bill please forgive me i forgot how to resize the pics . i reduced them from 8 meg each but the size is too big . Feel free to fit them . i just cant remember how .

@ Gadgetmall:

Nice looking bulbs! Are they LED? Do You or anyone else have any idea, how to get them? Who ships them wordwide?

@ Gary:

I do not want CFL. I prefer warm white LEDs. As far i am experimenting, i did not get enough light for reading. I have put some Seebeck modules to my woodstove and charge a 1.2V rechargeable. Its a nice way to get your own electricity The next step - make enough light to read, do more experiments etc.
