Joule Thief

So i made a coreless one.. and it's a flop, , 15 volts.. it does light an LED though.  Anyway. It was based on some celtic designs, I thought that the copper cutting through the center would increase relative strength, - perhaps I should do more tests.

In any event, it winds up beings a mashed together wad of copper with a continuous clockwise orientation, it was partly bifilar for the paths to contradict one another.

i see what your trying to build i think by what you describe .. 

yes that is deliccate .. angles must be perfect mass and it must be exact ... 

but  the coil i have just made will scare you ....  im not kidding ...

ist!

i bet it charges my cap pac ... almost too fast .... ; )

Use a copper coil as a core.  Bias the core so that the magnetic field produced by the core transmits the induced primary current  I think that is what innovation is up to,  Nice wraps too.

Jeanna:

That is a really cool light you made.  I really like it.  That was a very creative use of various things intended for other uses. 5 Stars!
