I made another side by side speaker wire phi ratio coil, so I could stack 3 of these coils.
I series connected and pulsed the top and bottom coil, and tuned the center coil again. it seemed to need 10nF so I used the 22x 0,22uf in series that I had used before.
Then I disconnected the top coil, and only pulsed the bottom coil. The top coil now became the resonant output coil.
Now the center tuned coil had a larger voltage rise, at a lower frequency. This I didnt expect (maybe I should try tuning the coil again with parallel capacitance).
Now I took the B emf from the pulsed coil, and fed it trough a series connected equal size 10nF capacitor into the center coil. This did not do anyting at all. I think the Bemf, needs to be higher in voltage, OR it needs to be converted into a sine wave(!) because the CARC center coil needs to add up. When it is in resonance, its a sine wave, so to add up, I would need to be fed with a sine wave, via the series connected cap.
This sine wave, I have seen before, with nelsons published circuit, based around a joulethief. the bemf is stepped up and the output becomes a Sine. This could be the sine needed.
The output coil shows the same sine as the center coil. It still is untuned. I still need to see what happens if I tune this output coil. But I think I first need to transform the B emf, into a Sine, and feed it into the series capacitor.
