Inductance of (*1)self-induction (or autoinduction) has a pulse/wave length less than resonance frequency of the coil, so splash is 10 times less. Measure the resonance frequency, and now knowing resonance frequency of the transformer, you mutiply it by 10. So if your resonance frequency is 1MHz, and your inductance splash will be 10MHz. So, for make slower this inductance splash, your frequency of drossel/coil must to take it(splash), his frequency must to be 10 times less. So if you have 1MHz of resonance, the resonance of droseel/core must to be 100MHz. For make him to slower all this. Make it longer in time. It(droseel/core) makes it slower when waves are passing. So other part, LS circuit/contour must be configured for frequency of the generator. So, for start measuring, you connect a capacitor, anyone you have (random), now you picked one, measure the frequency, but this frequency must to be a reasonable, like 20-30-40-50KHz, you measured the frequency of the resonance, so you must to tune the generator at this frequency, it must to be precise. You measure the resistance, where is a bit less, now you put a continuous resistance (permanent/fixed one). Then you put this "наоборотник", and then you can to pick up the resistance. To make run the generator at resonance frequency. The wave pass so quickly, and with a osciloscope you don't even see it. On "наобратник" you have waves, energy, you have splsh, you see it and then it vanish. Now I measure the resistance, and look for the lower one, and now I put "наоборотник". You must to build a resistance inside the generator (I think that he says, you need to tune a potentiometer connected to the generator). The frequency tune must to be exact. The tune is very hard. Some temperature changes will afect and this frequency will change. It does work fine with an exact temperature. If frequency goes somewhere, you will lose the effect. This build is unsuccessful, but working one. This is just a introductory/familirization work, for see the effect. The configuration is very hard, I took 3-4 days for me. I tryed first by picking a capacitor. But I saw that it won't work by just picking a capacitor, so I just started to measure the resonance frequency of the circuit/countour with differente temperatures. You start with 2x100Kohm potentiometers. Transformer and drossel are playing secondary role, LS contour/circuit and generator are important. Transformer give the splashes to drossel for selfrunning/selfpowering. Resonance is essential for selfpowering. So, the easier way is, to put power (power input?) through a diode. When you make selfpowering, you put a diode on power input, and you put a tool, miliamptermeter, and you see if it takes power or doesn't. You see if you have splashes or not. When you see just a 0, diode will not allow you to see in the negative way, it will only show you power input. When it falls to 0, it is selfpowering. In my schematic I have the diode, and switcher with a battery for this. So you put a miliampermeter between them, you put miliampermeter with the battery in parallel. You should put (*2)кт315.
(*2) Analogs if you don't have KT315
I started to translating the first video, and when I clearly understand what he says, it just doesn't make any sense, and absolutelly no useful information. And the guy who is speaking, only talk about resonances. Also he says some tools that I don't know, even, I can not to find any information about these tools in internet. It is absolutelly no sense (at least for me, but still, maybe I am wrong, but I don't see something useful).
