Replication of the flashlight device by Vladik Hook.. in  russian 4 clips..


"Well , I will explain the principle of resonance and how to find it . Only from my pocket harder will not : - \ .
I showed in the " Torch Video 1" I found resonance with ferrite cups, now explain in detail .
On the frame is wound coil , its inductance in cups should be 115 uH, cups on a copper foil glued to it connect oscilloscope . Generator rectangle looking resonant frequency ferrite , as it is in resonance ferroelectric his sinus will increase, the maximum amplitude of the sine - our band. It is a way to learn any frequency ferrite at home . Then everything is simple to use this resonance - you need to take it off , this teeter LC circuit for the frequency of resonance. One end of the circuit is always connected to the incoming capacitor , and the second key is switched . Here 's how it works , but on the Soviet ferrites is easy."

The #3 is very convincing.

Yea very convincing super capacitor connected to jule theaf
It works until small super capacitor is drained and than stops

Yes, the circuit works great as a JT all right, although the current can be a bit higher than a real JT might need. But at 10 mA input the LEDs are still pretty darn bright and the thing will run on a 3V button cell like CR2016 for eight hours or more. (I hope you saw the alt.snakeoil Video Report.)

So a supercap that would keep it going for ten or twenty minutes isn't too hard to imagine. And the circuit would behave just in that way, too, when he turned the pot past the optimum point. Goes out, then needs to be retuned/recharged.

The author would have to reskin the supercap because the videos show regular electrolytic cap labeling and cans.
Also a supercap can be conceivably inserted inside a gutted electolytic cap if it is smaller.  Like in a Russian Matryoshka Doll.

I think Akula was accused of this Matryoshka technique on a Russian forum and that's why he gutted his electrolytic caps on video later.
Vadik Guk never gutted his elcaps on video.
