Stubblefield coils (bifilar) and speculations

[1tesla01]

Bill,Has there been any post about hooking any Stubblefield coils to antennas like the link Jenna poasted.I was reading on this coil and it talked about an antenna hook up?Regards Andy

Jenna, Have you read my last two post? Regards Andy

hooking any Stubblefield coils to antennas

Hi everyone,
Andy,

This coil has a lot of unusual elements to it. It is both a galvanic battery and through all the same wires n things a capacitor.

That means we are to expect sparks or the possibility of sparks if the wires are slmost but not shorted by some distance.

( as an aside, I actually have one of my coils set up to spark across the 10's, just to see. The sparks are too small to see in the daytime and I haven't been out under the tree at night since I set that up.)

I truely think the silver globes atop the batteries in the pic is the capacitor that gets sparked somehow, etc.

One of the things we learned a while ago is that if you run dc through the wires they do a major destruct thing. They go rusty almost immediately., Remarkable.

IMHO the best place to add something like an antenna, would be to the core piece 1. I, for one, will put that off for later. I want to see what this does with the earth first.

It certainly is something to try.

Bill, thanks for your comments to help me understand electrical frequency. I am having a time trying to explain what I don't get.

It is in the electric circuit that has resonance that I don't get. or perhaps why it is called resonance, maybe. We are told that these coils we are making all have a resonant frequency.

But it is not the frequency of the parts. You cannot hit the coil with a hammer and match the pitch to get the resonant frequency of the coil. It cycles up and back silently without giving a sign that it is resonating.

I appreciate the input.

I looked at the coil I am calling broken today. If I connect the secondary of that coil to the core piece 1
I get around 204mvdc:
but It is going up now. But wait it turned around! It went up to 230mvdc and now it is going down.
It stops at 196 and keeps going.
I put a capacitor on it to capture its max and look at it.
That whole 1 1/2 cycles took about 35 minutes.

That is a kind of cycling but is it a resonance of that coil? It may be the resonance of the secondary.
And it is now in my kitchen drying out after its bath. what about outside?

Now this is an interesting opportunity:
The thing that is broken about this coil is that the wires are shorted together somewhere but they are not shorted to the core piece-1.

So, I can get a "shorted" reading from this coil across its secondary, even though I can't get much else, but cool eh?

OK for now, I will post this.

@Bill,

I am beginning to think that all I really need to do is fork over some cash and buy an oscilloscope.

Once I do that, I will probably be like all the EE guys who just 'know' what it is because they can 'see' it on the screen.

Now to the thrift shop bringing some luck along with my cash!

thank you
