Hi all,
I really never expected to be posting in this forum, as I had long ago given up on free energy, etc.  In the distant past I spent quite a bit of time experimenting with N-machines, Bedini stuff, and nothing ever panned out.  Every once in a while I poke around to see if there's anything interesting or new that might possibly have a chance.  Never happens.

A couple of days ago something popped up on Youtube that caught my eye.  Tinman's bifilar coil overunity.  It looked so simple.  I followed what he was doing and couldn't fault his technique or results, but I still couldn't believe it.  (BTW, I've been involved with both analog and digital electronics for about 45 years)

After I saw 3 people had replicated it, one with some especially nice scope work I decided to try it myself.  The result was disappointing.  Then on watching Tinman's video again, and noting the LED lit up when he was in the middle of switching from the input side to the output side, I realized that I'd made a mistake in my setup, and corrected the problem.

Now, it does appear to work!??  I don't know what to say.  I told my wife last night, while talking about this, that I placed the odds of this working at about 1%.  But there it is, output larger than input, same resistor values.

Details of build:
Pancake bifilar coil about 10" OD, about 35 pairs of turns, #22 or #24 flexible hookup wire.
BK  4001 FG
TDS210 Scope
Resistors both 150 ohm
Frequency about 700 kHz (for best result, but not a sharp resonance)

I tried just as Tinman did the first time, switching scope and scope ground between input resistor and output resistor.  Then I isolated the input from the FG with a couple of caps just to make sure I wasn't having a weird ground loop problem.  Still worked.

At "resonance" the voltage across the output resistor is roughly 3 times the voltage across the input resistor.

So, I have to ask myself at this point if I'm just buying into a bit of mass delusion, or if this is real.  What am I missing in interpreting this?  I should know better, but there it is (or seems to be).  If this is a delusion, at least I'll have a few hours of thinking that maybe, just maybe, this stuff is possible!

Hey Hfo   Welcome

I deleted your pic as it was up for approval and reposting it resized as the big pictures stretch the page a lot.  I use Picpick free pic editor. I set the image resize to 30% to get the right size.

Thanks for showing

Im out of this testing as I dont have a sig gen that hits the freq you guys are looking at.  Looking at another Hantek that is a scope and arb func gen up to 25mhz

Question..   Tesla referred to it as a given freq and potential.  If you change the input voltage does the freq you are operating to see the effect change? just trying to connect dots.

Oops you can't attach an image to an email so I am posting this here.

MH
Your confused

Below is the correct interpretation.,

I hope it is safe for me to post now.

TinMan, MH, you are both right as usual. There is significant capacitive coupling between the two individual half-coils of the bifilar winding, and there is also significant capacitive coupling from the open end of the L1 coil to Ground, through space.

The issue of the proper placement of the CVR is still under discussion and experimentation. I tend to agree with MH on that issue but "traffic continues".

I also want to make it clear that the schematic above is not mine, I just made the ground connections explicit in my edit. The original comes from Partzman, and his coil parameters are listed on that version of the schematic. He has been working on this for a long time, and I and some others are quite new to the program and are still coming "up to speed" as it were.

In my own work with that circuit thus far, I have found that there can be a _huge_ difference in performance depending on whether 50 ohm ordinary resistors, or ~10 ohm non-inductive resistors, are used for the L2 "load".  I'm hoping someone will "donate" a 50 ohm NI resistor to me so that I can eliminate at least one variable in that problem.



Mags, I would recommend against getting a combined scope/AWG, as the AWG function in those units is a compromise and generally has low power/voltage output and takes up processing and controls that are better left to the scope function alone. Two separate units will of course cost somewhat more but will be _far_ more versatile in your laboratory use.  Even a "cheepo" DDS AWG stand-alone is likely to be better and easier to use than the AWG built into the scope. But I'm just going by what people are saying on a test equipment forum, I have no personal experience with a combo unit like that.

In answer to your question.... in my experience, yes.
