Here are some old photos of my early experiments with the NS coil.

1.9 volts and 472 mA's. These are not millivolts but volts. (AC) Didn't you remember this Jeanna? (smile)

I have contacted several wire manufacturers in regards to getting copper wire with water permeable cloth insulation. I will let you know if anything pans out of it. I did this because I have become frustrated in keeping things insulated. The method I first proposed is ok but only with thin materials. Even then it is not optimal. maybe I am too picky but I too like neat constructions. The faulty coil episode was definitely a short but not a direct one or consistant one. So who knows, maybe this new wire expedition will pan out.

Quotemy biggest question now is if we opposed the earth's magnetics, will we get a response. I am trying to think of an easy way to try this out.

I have learned something from watching prof Lewin and today repeated by this terrific book.
Lenz said oppose and he was only talking about the direction.
It is used as resistance by everyone who refers to this here, it seema, and wiki and everybody else...
But Lenz was talking about the direction of the flow of electricity- not the reactance or resistance to it.
So if you apply a mag field in one direction, say up, the electric field will go in the opposite direction so down. There are many things that have been subtly changed or the emphasis has been changed. I am grateful for this book link.

@protonmom, I followed your second link and I am reading it online and I see all the pics. I will try again later.
I am also finding these old definitions very illuminating!

anyway, I found that the modern facsimile of the old timey wire is first coated with varnish then covered in cloth.
In fact, I do not see it right now, but collins refers to silk being better not for any properties of silk, but because it allows you to get the wires closer to each other. (This was a big bone of contention here for a long time.)

I must say this is true.
Those that I made with silk as covering are still by far the best.

The sources I have found for the cotton insulation are a little misleading. I found some for making old time radio restorations and guitar pick-ups, etc. This "new" old tube cotton actually has a teflon inner liner so it will not work for our coils. Just make sure to call and check it out before ordering.

If someone does find a source for real cotton (only) tubing, let me know.

Thanks,

Bill

PS

I think I posted this a long time ago but, think about cotton shoe laces. The kind on tennis shoes is really just a cotton tube that has been pressed flat. Now, I am sure this stuff is made on a big roll and cut off to the proper lengths needed. if we could find a source for this, it would be cheap and, be just what we need.

Yes, but I also remember that these diminished over time and could not be restored.
There seemed to be a certain level of galvanic reaction built in which worked for a while, but stopped.
I had milliamps in one too, but only for one or 2 days- and it was never to return.

I too got 0.97v the other day as shown on the EER, but I should have said I don't count what the dmm shows any more. I am so aware that it cannot see what the joule thief secondary can make, so I don't believe it on the EER either, since the earth oscillations are so fast, even the scope is unable to pick up a lot of it. (my scope, that is).

Here are 2 screenshots adding to one sentence with what collins has to say about silk and why. I included the page number too.

Good point.
