But that would produce different waveforms no?

No; it's the output of the chip.... can't say the resulting wave is exactly the same; apparently it's maybe nearly congruent but without a slight gain


a 1:3 transformer input and output look the same as a 1:3.5

if the foils are the same, the coil becomes directional also, so it's important to know which side was ground and which side was power....


you end up with a CW(foil), CCW(wire) and CCW(wire) inductors or CCW(foil), CW(wire) and CW(foil)

I am still waiting for an explanation for this fact:

We can produce waveforms that are identical to Akula's scopeshot, with the same circuit, but NO LEDs remaining on perpetually.

And the corollary question: How can a "wrong" ferrite material wind up producing the same waveforms when stimulated in the same way by the same circuit ?

The fact that the same waveforms are produced by the same circuit strongly indicates to me that we are using the same ferrite material, and/or we are operating at such paltry low frequencies that the material isn't all that important. I reject the claim-without-evidence that two "identical" circuits except perhaps the ferrite material, could make identical waveforms, but only one of them keeps the LEDs lit after removing power.

I don't see any identity in presented there scopeshots with Akula's scopeshot

Please point out the differences.

Try again; the connections are opposing... so you get cw, ccw, cw or ccw, cw, ccw


A) Reference wire pairs, 1 layer of tape removed; dark pair to the left(higher mH), white pair (lower mH).
b) How much of a gap the outer copper has; and the solder point for the secondary (white wire)
c) foil being removed, short wire cut, still is a pair with a white wire
(c-d) unwind primary, and a layer of tape between W1 and W2
d) beginning to unwind inner coil, from short wire that was cut in B
e) the gap of the inner foil, the connection point, oriented to match the others.


I really don't mind someone challenging me rather than letting me think I had it spot on; other than that the foils are only attached to the lower mH coil.
