Not a product, but I believe that will baffle a lot of you.  :-DD :popcorn:

I bow before Henryk Gasperowicz for pulling it off so perfectly!

All the problems I've encountered May end by seeking knowledge from this post.

Too bad. ;D
Note that the little schematic shown in the original video is completely misleading, so that it's very close to just clickbait material.

The solution at least gives something to think about. Now there's still fun to be had: try and imagine a solution for this simpler than what he did (simpler meaning, for instance, less components and/or no need for inductors, etc.) Anyone?

I know that the picture is misleading, but so are many presentations of dodgy technology. His project shows how far one can currently go with relatively simple methods. How easy it is to create a fake that seems to have no trickery involved.

He offered a simpler cirtcuit too — the one without switches.
