Selfrunning cold electricity circuit from Dr.Stiffler

[gyulasun]

In Dr Stifflers circuit above the Emitter seems to be shorted to the Base divider network. 
It looks like a Colpits oscillator so I guess it shoud be open at this point?

Yes, you are right. There should not be wire connection between emitter and base in that schematics, it is obviously a misprint.

There is another version of  the Colpitts oscillator where the capacitive divider (C1 and C2) is placed between the base (or gate in case of FET) and the common ground and in that case the connection from the emitter (or source in case of a FET) to the middle point of the capacitive divider is justified,  see like here:

I am getting now also about 20 Volts p-p behind L1. But then the AP LED is brightest, when I dont use L2 and  L3 at all. Just from the oscillator via  470 pF and 2.2 uH to the AP.
Then from one Pin of the LED to a iron metal plate gives me the brighest LED so far. More in about 10 hours.
Now to sleep.

Okay,
I made some new test today.

I just don?t have the right cores.

I asked Dr. Stiffler, if he would sell me a "working" coil-core
combination, but as he has got only 5 working core-coil combinations,
he declined saying that he still needs them for verification
with other parties involved.
I can fully understand this.
I will now try to buy some core-coils via Ebay.

I am now at around 27 Mhz working frequency
and the higher you go it seems to be getting better with the
Avramenko plug with my 2 x 1N4148 diodes.
At least for me 27 Mhz was better than around 10 Mhz.
The LEDs are just brighter.

Okay, I tried various setups but always the combination of capacitor
and 2.2 uH coil at the output before going into the AP was the best setup.
All the ferrite cores I had and also some ferrite magnets did not give better
brightness.
I now chained 10 blue LED diodes in series in the AP.
One pin of the AP is connected to power supply PLUS voltage
and then the circuit draws around 25 mA at 12 Volts, that gives about 300 milliWatts draw
from my powersupply.

When I remove the AP from the circuit , the circuit draws 17 mA, which is about 200 milliWatts.

I can light up these 10 LEDs pretty bright with the difference power of 100 milliWatts,
but if this is overunity, I can not really say yet...

Have a look at it yourself. Here are 3 picture, 2 with the AP running the 10 LEDs
and once the AP disconnected...

As this circuit is so high frequency, all cables length already matter.
When I connect the 2.2 uH coil directly on the breadboard without these green
cables, the AP does not light at all !
So it really depens on some cables between it and probably on electromagnetic radiation
and standing waves...

I just don?t have the right equipment to measure these RF currents correctly, so
all measurements at this level must be taken not too seriously...

Also the breadboard itsself with all the capacitances between the rows and contacts
surely change the circuit into very much capacitively coupled things...
So as long as Dr. Stiffler still uses his breadboard with his aluplate in the
background there is this huge aluplate capacitance, that really matters at these
frequencies !

These RF circuits are no joy for audio frequency engineers !


Well, I will stop now with this circuit, as long as I don?t have a core-coil
combination that seems to give me any gain...
I did not see any gain in my core-coil combinations so far.

Also the lighting of the neon bulb with one of my aircore coils in my earlier tests
had not had any big output, this was probably only from the right frequency
to excite the neon gas inside the bulb and was probably just a few milliWatts
of power there. Also it did not hurt me, when touching it...
So all in all, this Avramenko Plug technology is interesting but I could
not yet get any power amplification from it, as I don?t have the right cores...

P.S: The first 2 pics had the same LED brightness, butI held the
camera in a different angle, so in the second picture the LEDs
just seem brighter, as they were more in direct line with the camera.

The meter you see is set on the 50 mA DC scale and was hooked into
the positive supply line ofthe 12 Volts power supply with a cap across the leads,
so it did register just the DC amps.

In the 2 upper pics you can see the current of about 25 mA
in the last pic, when I removed the cap( so the AP was connected anymore)
the oscillator circuit just drawed about 17 mA.
Then the oscillator was just idle running at around 27 Mhz with no output
connected.

If you have some questions just ask.

What I also saw is, that the input power did rise more,if I did
connect one pin of the AP to the external iron plate instead
of the positive pole ofthe power supply,so
it seems in this case the RF power is just better transmitted away and
so the circuit draws more input power.
So connecting one pin of the LED chain to +12 Volt or the ground of the
circuit just worked best as this draws only 25 mA, in the other case
it drew about 40 mA !
Just running the AP without the connection to 12 Volts or ground did not work
in my case.. only, when I had the AP off board, so all the cables were between it..

You see, these RF frequencies are nasty to work with...so many dependences
from capacitance and cable inductancs...

Well,
I ordered now 10 pieces of 680 uH ferrite antenna:

and
10 pieces of 470 uH antenna ferrite sticks:

Hopefully I will soon get it via airmail and then I will
continue with this project.

Until then I will try other circuits.
