Tinman does some interesting things?

Lol-that was fast

OK,i left the first two parts out of the video-long and boring.
The core i made from cast iron powder,and set with two pack epoxy.
The primary and secondary are wound together(1:1) at 1 layer each dimension.

I carried out some further experiments,but will leave them for another day-as it is late here.
But the results i am getting are like no other transformer i have tested so far.

Further updates to come.

Thanks for the details mate interesting stuff.

ok so it's more like bifilar and on a core.
Made one while I waited around 1.5x1.5x1.5 inch wood block... with telephone patch cable (blue/white bifilar)
played with using center as a winding and outside as other windings... it somehow managed to translate a signal to those  even though they aren't parallel in any way...
once I saw your response reconnected all blues and all whites...
do get a good signal transfer... I have a newer signal generator, not really sure about it's input character (how much power it can generate) yet... but do get a good resonance right around 1.0Mhz without a capacitor... can add a few nanofarads and lower the frequency of resonance but then I get lower output, and of course that's much higher input power since it's on longer.  It doesn't have a pulse setting and is kind of tricky to get bias to 0 (course analog resistor settings)  and changing the amplitude changes the biasing too...


It IS interesting; need to swap it for a toroid coil.... but the few I tried had too high of resonance; and those really didn't like having capacitance....

hello d3x0r et all,
I just posted this comment in Tinman`s YT channel:

ideas are like bubbles floating in the aether, this one just lightly grazed me in 2011, but never developed it !! http://overunity.com/6123/joule-thief/msg305125/#msg305125

I still do not have a scope so I cannot go further blindly !! . . . but very happy of Tinman catching the same bubble !!

cheers
Alvaro
