FE Device by 'Armored Train'

[TheCell]

Hello

because the schematic is so damn easy , but seen others at YT ,who failed to replicate this, I suspect the ferite core to be self made the chosen materials to be crucial for function.
After winding the 2 coils , did he glue the both halfes together, or is there an airgap in between. Both the leds and the charging cap are fed by the same pulse , but it is not clear whether it is the active pulse or the flyback pulse.
The parameters frequency / duty cycle are surely of further interest, but :

Can someone contact this person to answer above questions please ?

I made this about two years ago. I used a ferrite core from an old TV flyback transformer. These normally do have a tiny plastic spacer (like 0.2 mm or so) to make an airgap but I can't remember if I used the spacer or not. I used a rubber band to pull the two halves of the core together, no glue. And I can't find the silly thing at the moment, it's buried in my lab mess somewhere. I made the PCB by hand using the template that appears on the website you linked.  By the way, you can put the web address into Google Translate and get an English (or whatever) translation of the page. Then you can read the Comments... they are very interesting.

What I can tell you is this: There are differences in the MC34063 chip from different manufacturers. First I used one that I removed from a car cigarette-lighter cellphone charger, then I got a batch of 10 from an Ebay seller in China. I can't remember which ones worked better but I do recall that they were different.

The thing is a fairly good receiver of wireless power. But of course you still need a source of the wireless power for it to receive.

-> but do not reveal enough

Maybe T-1000 should contact this person, if he is willing to tell the details.
Anyone can start the guessing game: resonace frequency, nr of turn ratio, ferite material  ect.

Because I don't think setups like these are impossible: EP1033807A1

TK,
It could be made without have any wireless transmission power or any output source , in fact is just a more efficient way of discharge a cap .
