I was only referring to the Russian site which implied that the design was a fake. However, if you have managed to make it work it would be a great help to anyone who's trying to replicate if you were to give that more details about the design.

As a matter of interest I will assemble the circuit in a few days when I have a bit more time. Luckily I have all of the right components.
The results will be posted here. Stand by...

So, how I see, conected to inverter have little ticker wire and 30-40 turns, it is on top. Conected to transistor colector and plus have 50-70 turns of little tinner wire and it is inside.

I also see copper tape under and over first winding, how is it connected, to ground?

Look Mr Semenihin's  diagram (schema ньюфонарик3.JPG ), it is one primary 10-12 turns and no copper foil.
The secondary has  3 coils, two copper foils and between them are 15-18 turns.  A copper foil means one turn with a little gap.
Yes, Yes, thank you, Mr. Semenihin !!!
Please, Which is the button for correct my Writing ?

A (big) step in the right direction. This might jump-start successful replications. Kudos to you!
