I not shore is here feroresonance. Here is other circuit. To find ferorerosonance use one turn on primary and one turn on secondary, on secondary put 10 omh resistor and oscilioscope. And put into primary from range 800-2000 kiloherc frenquency of 5 volts and were you get maximum amplitude on that resistor, here and is ferroresonance. Seems i write coresct. Akula say about one turn... but other part of his words I now not remember. Need relisten conference....
Or you can use other numbers of turns, if you get same frenquency of fading out vibration, then here can be ferroresonance...

This is one of the standard ways of determining resonance in a coil/core. What part is the "ferro" part and what part is just ordinary electrical LCR resonance?

Please do re-listen to conference and let us know what you can get from it. I am finding your comments very helpful, actually, even if you are sometimes wrong!

By the way... current draw is 110 mA at 3.0 V and when I pull the power it takes the LEDs about 4 seconds to fade out completely.




I am afraid to say that I have Joule Thiefs that do much better than that and use a lot fewer components.

Questions!
sorry!

110mA at 3V is way too much. All you need is to generate spikes on driving transistor and shut it off as soon as LEDs get lit then wait until capacitor gets discharged and LEDs are in off state again before next pulse train...

Also for resonance - the effect is same as per Lithuanian experiment just on much smaller scale which is not harmful to health. So you need to reach NMR conditions of black hard ferrite (won't work on greyish soft) to have additional energy input there;)

yes, you opened the toilets doors in the bank. there is no money.
