So you can not replicate this schematic? If you say, that it is exatly like Vadim schematic, then it is not exatly like Vadim, here many diferences, inductance not that addadet resistors and so on. If you replicating Akula divice with pot core, here also not exatly like in him, because he in video say, that other generator not used, but you using two generators, he use ony one.

What are you talking about? I am using the schematic you linked, yes. It has only one "generator", the MC34063 chip. Please explain how I am able to generate the exact waveforms that Akula shows if the circuit I am using is wrong.

Why don't you show us some of YOUR work? Let us please see YOUR version of this project, and please don't forget to show it running without any power supply attached.

If this words to me, then let me see you drawed schematic. And I nothing say, that you core is from not good material.

I have showed my drawed schematic many times. Each time I make a variation I show the variation. By exploring _many variations_ I have identified errors in what has been reported -- the inductance values, which side gets which inductance, the fake "80V p-p" report due to his mis-setting attenuations.... and I have now arrived at the same instrumental measurements that Akula has shown. And you are waving your hands about and doing "special pleading".  Go ahead and send me some magic ferrite material and I'll be happy to test it, since YOU CANNOT REPORT ANY TESTS OF YOUR OWN that support your claims.

I have added ONE resistor to the original schematic, based on a suggestion made yesterday. It helps and hurts, as I have described above. I have changed the value of ONE input filter/reservoir capacitor from 2200 to 3300 uF. I made up the 0.33 ohm value by paralleling three 1.0 ohm resistors and I made the 510 pF value by putting 2 1000 pF caps in series and finding ones that would give the 510 pF value exactly.  Akula has shown many circuits "working" with a flyback ferrite instead of a pot core, including this one, I thought.

If you want to criticize my work, please do not misrepresent it while you are doing so. If you think that the 3300 uF cap is an "unsuitable" substitution... I'll be happy to change it. What do you predict will happen when I do?

I am still waiting for an explanation of how, if my circuit is somehow "wrong", I get these waveforms.

(Don't forget that Akula's scope is not showing 50 v/div but is actually showing 5 v/div and at less resolution than he could be using if he had set his scope correctly. I apologize for having "garage sale" equipment.... but at least I know how to use it. )

hi TinselKoala,

It's afternoon over here.

I took a look at the circuit once more.

I do find there is no recovery at all from higher voltage potential found across 1000uf capacitor and back to the MC34063 in order to create a self run.
It looks like-The higher potential is merely used to power 2 led in series besides charging 1000uf capacitor and also serve as voltage reference for P1 base on current circuit layout.

Can you try to see if there is any drop in input current after connecting wire(temporary) from output of D1 to MC34063 pin7.
Do try to connect battery or 3v power source few times to circuit -Akula style as seen in video for 2nd experiment after connecting temp wire as well.

I'll try what you suggest, along with all the other suggestions I have received from people who seem coherent and have some actual knowledge. I must say, though, that I am getting fed up with the special pleadings, handwavings, and the resorting to more claims without evidence. I've shown to my satisfaction that the circuit I have constructed isn't picking up significant energy from the environment, that it can be made to run for a _long_ time on tiny concealed batteries, and that the circuit works to make the instrumental measurements that Akula has shown.... in short it does everything that Akula has shown. Everything. Akula simply has not shown yet where he hid the battery or the tiny thin supply wires.

If you want me to believe that different ferrite material -- the Soviet material -- will perform differently, please provide some evidence! And if you say, "well, look at Akula's circuit, he uses Soviet ferrites and they work!" I will just laugh at you. (Do we actually even have evidence that Akula himself is using "soviet ferrite" material? I'll bet his are made in China just like everyone else's.)

Akula use one generator and not clearly see how it circuit conected, so I not recomendate replicate akula lantern with pot core. I recomendate replicate lantern with two Tl494.

Tinkola, and indution not 5.9 miligenriesa and 2.6, miligenries, but 59 and 26 miligenries must be, if you replicating akula lanter with pot core. In video seems is 5.4 milihenries but writen 54 milihenries, see how many errors have this circuit? Or maybe here microhenries?
