Mysterious Resonant Circuit

[EMdevices]

I remember Bruce,  you had switched a transistor around and it ran, LOL,   maybe we should purposefully change things around, we might never know what we're about to discover.

poynt99,   the 17.5 volts is the amplitude, so the voltage swings up to +17.5 volts then down to -17.5 volts,   that's why I devide by 2, in my power output calculation.

Peterae,   the output resistor gets hot within about 3 seconds, hot enough that I can't touch it.   Obviously I disconect the battery real quick after I take my scope shots and freez the image on the scope.

b)  The mystery comes about due to the polarity of the windings.  Look for the black dot on the coils, it tells which terminals have the same polarity when the flux is changing through the core.   In normal oscillators (like Armstrong, Blocking, etc..),  the trigger winding should be reversed from what I show, so that when the Base is (+) and current flows, the Collector can pump the resonant tank.  Also, notice the collector voltage waveform, notice it's  NEGATIVE when the NPN is on,  I sure haven't seen that before and I'm not too sure what the transistor is doing.  I'm sure it's internal parasitic capacitance playes a part.  Maybe even negative resistance is at work here, not too sure at this point.

Because of the frequency and the scope shots - I wouldn't use the terms "on" and
"off". There is even e big phase shift between base and emitter.
And what I see from the battery scope trace makes me no wonder that
the thing works with neg. ucoll.

Howdy EMDevices,

Excellent Work.  I kind of jealous actually.  I am sure there are many ways to tap ZPE, and in the coming months and years there will be many more.  Your blocking oscillator is a catalyst.  This one breakthrough will hopefully cause a cascade effect and the hundredth monkey effect will kick in and we will start seeing breakthroughs all over the place.

Again, Excellent Work!

Blessed Be Brothers...

guys,  I'm not going to answer anymore questions for right now untill I post the latest scope shots,  tonight when I get home.

the new waveforms that go along with my OU claim are very smooth and sinusoidal, compared to what I posted above in the first post. The battery RF is now effectively suppressed as well, like I mentioned already.  Just be patient.   I though it through quite a bit before I dared to post such a bold claim this morning, so this is for real, I'm honest, and I hope I did not leave something out that is basic and embarassing.   Let's hope not.

P.S.  Just as a side note,  as I was experimenting last evening, trying to supress the RF on the battery,  I noticed that shunt capacitors across the battery did not effectively short the RF, and instead caused a weird chaotic wavforms, and made the core "sing", meaning it made audible sounds, these sounds also can be produced when I vary other parameters.    Then I tried a small toroid inductor in series with the battery to block the RF, since the inductor has a high impedance at high frequency  (Z = jwL), but I noticed something very odd.  the waveform on the scope started to modulate in frequency,  I was getting FM modulation from 20 kHz up to 50 MHz and back down, then back up, very strange, I have never seen that behavior before.   It was also very sensitive to the touch of my hand.   Anyway, lot's to explore with this circuit.

@EMDEVICES

GREAT WORK !!!   

I  also claim overunity  well lets call it unity 

how ever my unit is much diffrent 

and i will be up dateing my thred today

i have come up with a number of ways it can be wired 

agin good stuff congrats emd!!
