Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

[protonmom]

My goof is that I called it a Secondary reading, when I should have called it a SecondaryPrimary or something like that.

8 layers of primary and over 200 windings of secondary.  Primary is approx. 20 ga and secondary is approx. 22 ga.  Primary wires covered in cotton only.  Secondary is mag wire, so no covering at all.  Center bolt is iron insulated in electrical tape   End disks are wood.

So are these good readings then?  If I were to bury it, surely I would get higher results.
**
I also have a big baby here that gets pretty good reads off the primary.  Once it has cooked in the ground for a bit, it might even give us something good from the secondary..  The latest read on THAT coil is as follows:
V.  200=.8                A. 20m=12.91                 Batt 1.5V=.409
     20=.85                     200m=18.6                 9v=.620
      2=.869                                                12V=.66

No secondary on that one as of yet.

All my bolts in my coils are about 9 inches long.  The end disks are about 4 inches wide.  Most coils are filled up to edge of disk, or as close to it as I could get without running out of wire.  The biggest coil yet has disks that are 6 inches wide.  Once I get enough wire prepared, I will start adding  secondaries to those coils.

I have a scope but have not learned how to use it yet.

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?

Like the patent , that way every layer work in the same direction(to make a better electromagnet ).

OK this is the results on the primary.
Thanks.
I crossed out what you do not need.
You do not need the battery thing, unless you are totally lost.

Do you see that
0.8v and
0.85v are the same on those 2 lines? It is just that the 0.85 is more accurate.
The one in the range that maxes at 2v shows the most detail and gives it to you in mV so it tells you 869mV
which is just more accurate.
You want to use the most accurate and detailed you can, so turn the dial to the smallest where it says 1 then turn it up a notch.
I used to turn it up 2 notches when I was starting out to be sure I was understanding.
And, please believe me there was a long time when I was not able to get this either. Just keep plugging at it, and you will too.

Thank you for the details.
You have some very big coils.
I think you stand to be the first to get something useful from a NS coil secondary here.

Can't you find any silk?
It makes the wires so much closer to each other. It is my coils wound with silk and using annealed iron that gave me any results...(the little green one #3,  did from the get go. It is just too short a secondary)

[protonmom]

Yes, Silk is on my list of to-do projects.  I just like working with the cotton better as the silk frays so much.   Eventually I will use some silk.

Thanks for trying to explain those numbers to me.   So, I should just go up one from wherever I see a number 1 and use that as my reading.  I almost always get a 1 on  the V 200m, so I should just use the 2 or maybe the 20.

As you can probably guess,  I plan to keep making coils.  Each one may be just a little bit different from the others, which is good for comparison.   

Question…..
Why is it that I am able to get AC readings on these coils sometimes?  When I do, I re-check them and it still comes out the same.  Is that just a fluke?  Or is it because the coil is oscillating, which this last one and the big one both do. ??   Would that cause the meter to give AC readings?
