I left you a link right when you asked for the torroid suprise its a multi pack for a few bucks  and the leds and what not.

Ive seen the cycling and i have seperate readings between the copper and the bolt lower than with the iron i might add.  i dont want to bring these up now because i don't want folks confused.

My coper is solid not stranded its larger than the diameter of the ink tube inside a bic pen..

Here this is a photo of my latest cell the one i've been taking readings from

@ Jeanna:

If it is really ferrite (iron oxide)  you will need diamonds to cut through it.  All of our tooling was diamonds.  Ferrite is not as hard as aluminum oxide (al203) but it is close.  Put it this way, on the Mohs' scale of relative hardness, al203 is 9, ferrite is like 8.7 and glass is 5.5.  Diamond is 10.  Way harder than glass.

@ All:

I completed re wrapping my 2nd coil and, tah dah, no shorts.  I need to get to bed but i will wet it in the a.m. and see what happens.

Hi to all you builders.

A suggestion for a source of soft iron wire.  In the USA, if you go to the building material outlets like Home Depot or any builders supply, in the construction dept, they have iron wire for tying  rebar together.  Rebar is short for reinforcing steel in used in making poured concrete forms.  They rebar varies in diameter from  3/8 inch to one inch.

The tying wire is very soft because it is made to wrap around the rebar to hold them together before the concrete is poured.  I don't think it is coated except for maybe a thin layer of paint.  It rusts very easily after getting wet. 

So, don't look for wire just where the wire dept is.  Go to where the construction supplies are and ask for wire to tie rebar together.

Hope this helps,

@ All:

First tests with the new cell:  (This test was one with just wetting the cell in the sink)

.79 vdc
15 mA
1.0 vac

This is identical to the results from my single layer coil.  This one has two layers.  No difference that I can see.  Interesting.

I blew out another fuse on my digital meter while testing this. (I have no idea why)  I had to use the analog to measure mA. It is a .5 amp fuse and should not have blown from what I am measuring here. (I would love to have .5 amps)

Has anyone else achieved more volts and/or mA with additional layers?
