Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

Hmmm…………….Upon  taking a closer look at my coil, I am going to have to say it is a SecondaryPrimary, not just a secondary.  In effect, I am using both the primary and secondary together as one long string.

I just finished my new baby  (coil number 6) and I think I have good news for you.  I believe I have gotten readings off the secondary!  I am at a loss when it comes to actually reading the DMM as usual, so I will just give you all the numbers and hope someone can interpret it for me.
V.                   A.               Battery
200=.8      20m=.22      1.5V=.014
20=.90      200m=.1      9V=.21
2=.916                      12V=.28
200m=1

Remember this is off the secondary!

This is great.
You are getting 0.9v from your secondary as read by the dmm.
We know from the joule thief work that this number is low and likely to be much higher than this if you were to read it through a scope.
Maybe even 10 or 20 times higher, btw.
 

All my coils are started at the top and end at the top, but I noticed some people start at one end and finish at the other.  Don't see where it makes much difference, except I think it is easier to have both at one end.

That is how he pictured it.
In his patent he refers you to the picture.
The funny thing is the picture is either incomplete, or wrong, because you cannou have an odd number of rows that end at the same side as the beginning.
Oh well, here we go again!

I am so glad this is coming together like this.
I took scope readings this summer but the ac showed less than 100mV.
Great going.

How many rows and ABOUT how many turns are on this and how many on the secondary please. This is very important for us all to know this.

thank you,

Mk1,
Yes, the bolt and the layers are covered in cotton.  What did you mean by the windings are directional for better electromagnet?  Did you mean  we should start at one end and finish at the other, or did you mean we should start both at one end and finish at same end?  I think Stubblefield showed us to start at one end and finish at same end.  Which way do you make them?

[protonmom]

Jeanna, I am not sure you still want that info since I goofed up.  I cannot now say it is off the secondary alone.  Still want the number of windings etc?   If so, give me a minute to check.

[jeanna]

Yes, and I want the details of the goof too.

Thanks.
