Stubblefield coils (bifilar) and speculations

Re:

Still playing with the coil, a lot of fun and strange things.

I got it to go up to 1.8Vdc now and steady at 0.610Vdc after discharging it for a few minutes. At one time I was shocking it with pulse with a 9V battery and my multimeter went crazy. the coil after the pulsing was going from 1.2Vdc to .7Vdc to 1.1Vdc to .9Vdc for a few minutes, checked AC, it was crazy there too, going from .02Vac to .105Vac to .2Vac etc... It was oscillating. Shorted it and it stopped, can't get it back to do it.

Well off for the shock treatment.... 

Take care all,

Hi all,

The thickness of the insulator might have a role to play in longevity because the small coil after a long draining session with a 1/8 watt resistor has left its potential to 0.045Vdc. Seems to be stuck there for now. I used a thin layer of cotton, thicker may be better. Worked well for 2 days. I'll see what comes up with it in the next week or so.

Take care,

Michel

EDIT: I just squeezed the coil and it must have move something inside as it is now going up to a steady 0.430Vdc.

Re:

Took the coil apart and the rust is showing through in many places but still not much. The first time, I wound the coil tight and rewound it with much less pressure. Resealed it and it is now at a nicer 0.608Vdc.

Restarting the tests and shocks.

Take care,

Michel

I am having another sleeve made for big brother, it will have 4 layers of cotton as insulator and wont wind it as tight.

Since I am here, I thought I'd mention what is going on outside.

I put a non electrolytic capacitor across the 2 10's wires. (the kind that looks like a soft plastic blob on 2 wires.)

The voltage shot up from 30millivolts to 263 millivolts. And the amps read 545microamps too. This doesn't sound like much cuz it isn't  BUT this cell has been dry all summer. I added water to the soil. That is when it showed 30 millivolts.

That was yesterday. Today in the early morning the volts were 200millivolts. The amps were 145microamps. I think this is the solar thing. early morning is less high noon should be more. I'll check.

G'day all,

Way ta go jeanna
