I know, right?
Anyway, I am re-building the circuit again. At some stage the voltage increased even further and the coil started 'dancing' around the table. Then (with a big spark) both LEDs, MC34063, and a couple of capacitors gone up in smoke.
BTW, the power supply is limiting the current to 100 mA max so all that power didn't come from the PSU.

I suspect that your 1kv and even the 540 v readings are erroneous. Look at the components in the circuit: 60 V is well over the ratings of everything except the wires themselves, unless you used unnecessarily high voltage electrolytics.

Yes, I will bet my bottom dollar (not far away now) that all the power did come from the PSU, and was stored in the capacitors until it was released through a failed component. Just for grins, charge up a 2200 uF capacitor to 60 volts then short it with a bit of wire. Report your experience here, if you can still see to type.



Good work anyhow. But what are the black clipleads attached to the front face (calibration terminals?) of your oscilloscope? Please explain, I've never seen anything like this in use to make a measurement before.

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.

TK:

This is a very logical conclusion with which I totally agree.  Folks can make of it what they will.  Duplicate the waveforms but no O.U.  Maybe you should try your circuit in his lab?  As I suggested a while back, before you told me that his device ONLY works in his lab, it is receiving energy from somewhere, probably man made.(Electrosmog)  This would not make him a fraud per se, but it would explain what you are seeing in your lab.

Has anyone asked him why he thinks his circuit only works in his lab?  What does he think the reason is?  If this turns out to be the case it is still cool as it is "free to him energy", and lighting leds for free is always a good thing.  I like this result much better than recovering supercaps with regular cap sleeves.

I guess we will see?  Great work on this by the way.  As always, I learn a lot from you.

and difference in the windings of the inductors....?

But that would produce different waveforms no?
