Stubblefield coils (bifilar) and speculations

Nice avatar.

@ Jeanna,

Nice avatar, maybe I should make one too. 

My alternator is almost done and next will be to match the Newman to it then I'll work on the NS cell full time. I wound one last week that I am testing and so far with a 1/8 watt resistor across the terminals that gives a constant 0.460vdc @ 0.30ma (two days ago it was only giving 0.360vdc @ 0.20ma). So the resistor conditioning is helping.

Take care,

Michel

Thanks guys, ,

As the coil gets dryer the numbers go down. Today I saw some oscillations in the numbers both volts n amps. My guess is that the coil is using the battery from the meter along with the cap for this but I couldn't say how.

I have a plan for later this season. I am too scattered with life events for now, but when the rain settles in so will the energies.

Here is my plan, so if anyone thinks it is worth a try go for it.

-Make 2 similar coils with heavy enough gauge for some kind of amperage to show.
-Twist the 10's together. on one of them
-Put a cap across the 10's of the other.
-The one with the cap will be the pulsed power source for the other. It's copper wire will be the         
       (+) of the battery and the iron the (-) side.
-The one with twisted 10's is rigged up like a joule thief. with a resistor and a transistor as  switch. and a light. (the twisted ends attach to the - side of the other and the 5 and 6 make the loop circuit that has the resistor and transistor and light.)

Then start to take away the transistor, resistor and see if just the oscillator of the one with the cap will make the light happen.

I might even start by putting the joule thief I have on this to see that.

It was the last idea I had before I stopped last spring. I still want to follow this thought.

Oh yeah, thanks Michelinho - I forgot the resistor part. I'll need to do that soon too.

I tried 2 other caps to do this last year and Ian set me straight with this little blob. 

I have always felt that the NS coil generator had an oscillating current. I didn't know how to show it. I tried a small spark gap, but I couldn't tell. The other day, Ian explained to me that this blob type (he used the proper term, of course) is the kind that will allow the oscillations to occur unimpeded. They wonk back and forth in this particular kind of capacitor.

So

Thank you, Ian

2 days ago, I bought a bigger cap.

(BTW- the one I tried first is .01uf capacitor polyester film from RS
the results were as I said .)

I put in a .1uf cap (ten times larger capacity) same type 2 days ago. The volts n amps were the same for a while.
Next day they were 330millivolts and 1.45 milliamps (yes, milliamps).

Yesterday (so one day later just sitting there with the cap in place) I added a 300R resistor to the other ends the 5 and 6 wire ends.

The volts n amps changed to
70millivolts and .5uAmps.

I wish there were a way to attach these ultra thin wires together better than these clips. It is pretty shaky for a connection. I would be changing them more frequently just to see the differences.


It is foggy now, I will take the measurement around noon. Hopefully the fog will lift so the reading has some equivalent sun effect to the last few days. I want to see what effect this resistor has over time.

The odd thing is ohms law. E=IR so, R = E/I so 300 ohms = .07volts  / .0005Amps But that is not a true statement. I think the meter is really throwing the results off.  .07 / .0005 = 140ohms not 300ohms.

I wonder if this is showing ac?? and the meter can only read half of it? I will look at the ac volts right off the meter. Trouble is the meter guesses the ac volts are double the dc volts, so it wouldn't be proof.
