Electron Reversing Device

[poynt99]

The problem with measuring the input to the SG from the battery,is that the SG uses 32ma at 12.5 volts befor anything is hooked up to the output side.So where already useing more power with out a load hooked to it.

Each element in the system needs to be measured and accounted for, in order to properly sort out any suspicion that there may be excess energy entering the system somehow.

It's also helpful to treat everything beyond the battery as part of the total load. Although the FG is supplying energy to the rest of the circuit, it too uses energy. As such, it can be likened to a resistor that passes on energy from the battery, while dissipating some power of its own. Therefore, it really is a load. The only true source in the circuit is the battery. Hence; PBAT - (PFG + Pcircuit) = 0

I did quickly try two other air core coils,one from a MOT and one from an old project-niether worked.
Im guessing this is because they have no capacitance.

Perhaps, but all coils exhibit some capacitance. In the case of a Tesla bifilar however, that capacitance is significantly increased.

Do you get the same effect from your sim .99 if you remove the 50p cap?

I did not try it as I am waiting for the DC measurement of your coil.

I also must admit that i am unsure how you can disipate more power on the output than you are consuming on the input?
To do this,wouldnt the components have to be over 100% efficient themself?

It's a matter of perspective actually. What you are calling the "input", isn't really the input at all; the FG is. The battery is the source, and everything else beyond it dissipates power and therefore is a load on the battery.

I don't think I answered your question above.

The coil is part of the circuit, and therefore it receives its share of energy from the battery. However, unlike the resistors and diodes in the circuit, the coil stores rather than dissipates that energy, and then it returns that stored energy back to the LED's rather than through to the relatively high impedance path back through the FG. That's how the LED's are able to receive more power than the series diodes and meters (D1/R1, and D2/R2 in my case).

I'm sure my coil has capacitance... how could it not? I have no idea why my meters aren't reading it. They do read down into the low pF range when tested with actual capacitors.

My coil has inductance of 670-695 microHenry, measured three ways ( ProsKit MT5210 and Arduino inductometer, and resonating a tank circuit and calculating manually) and a DC resistance of 3.9 ohms (also measured with three different meters, ProsKit, Fluke 83 and Simpson 464). 60+60 turns of #27 enamelled magnet wire.

But I can't get a capacitance reading with either capacitance meter (Fluke, ProsKit). If I put a small cap (22 pF) in parallel with the coil, I read a short. If I put the small cap in series with the coil, I get the value of the small cap. Ditto with the other bifilar coil (the one used in the "coreless" JT video from a few days ago.) No capacitance reading, inductance about 125 microHenry, DC resistance 1.4 Ohms, 23+23 turns of plastic insulated #26 stranded wire.

I just made another matching bifilar coil to play with, and I'm changing the 1n914 diodes to 1n4004, changing the green LEDs to some other ones, and will resume testing after I've rested up some.

TK,

Did you remove the connection between the two coils to make your capacitance measurement with the meters?

You would then be measuring between two open-ended coils. I assume that is what tinman did.

I had strange effects measuring a spool bifi capacitance. Measuring capacitance between the coils(coils not connected electrically, open ends) like 11nanofarad, but when I connected the cap meter 'across' one coil, as if to measure resistance, it measured near 1uf. Either coil.

I was impressed with this amount of capacitance 'between' the coils. till I realized I was measuring across 1 coil.

Very strange.
