Selfrunning cold electricity circuit from Dr.Stiffler

Thanks for the video and the pictures, plengo.

Maybe your connection cables are already having enough inductance to get the LEDs to resonate at  about 8.5 Mhz
together with the board stray capacitance ?

Please try it with a ferrite choke in series with the signal generator output .

Please test then if you can get a neon bulb to light up,
this will then be a high voltage uptransforming.

Many thanks.

P.S: You are using 10 Volts peak to peak.
Dr. Stiffler is just using much less inpt voltage and
gets a gain power amplification from his ferrite core-coils...

Hello hartiberlin ,

I tried, as you asked, with 3 different coils in series with func.gen. (picture shown). All it did is change the frequency that the LEDs light up. Ex:one will be at 900khz, the other at 13MHz and the other at many different points. No brigthness difference. Concerning the neon, no high voltage anywhere. This is as simple as it can get.

Fausto.

ps: you're right. He is showing lots more than just LEDs lighting up, hight voltage and all. My design was just a simple experiment that allows you to use a reasonable amount of power with ONE wire and nothing else and still it is not coming from the FG (at least I think so).

Hi plengo
and all,
as long, as we don?t get the high voltage from a neon bulb
on another coil end ,so long we will not have any
power amplification.

I just tried a few more different cores and coils  with my function generator
going only up to around 3 Mhz, but all failed
to get me any high voltage on a neon test bulb.

NowI am going to sleep and whenI wake up I will
build up a 74HC14 oscillator which can go up to 20 Mhz with
square waves.
Then I will be able to finally see, if I can get the cores
better to resonate.

As long as I don?t have the right frequencies, there is
really no way to get it done otherwise...

Maybe Ron can still try his circuit on a different core-coil
setup, so we can see, how important this is.
Maybe he is also getting it to run on a standard ferrite
choke or a standard ferrite transformer with the right frequencies ?

Regards, Stefan.

Hi Ron,
can you please modify your core with the coils and
try to wind your own primary coil with normal copper wire( not litz wire)
around it and check, if this then also resonates so well
and gives you the same output power and neon test bulb glowings ?

What are the requirements to get the power amplification ?
Must it be this special ferrite core you have or or is it its flat shape
or is it the Q bandwidth quality factor of the litz wire coil ?
So, we really need to find this out now to scale the effect up.

Many thanks.
Regards, Stefan.

Hi Fausto,  Maybe your function generator ground is actually connected to earth through the chassis and plug of the generator.  If this is the case then you have actually provided the second function generator connection in a roundabout way via your earth lead.  If you measure the resistance between the mains earth pin and the function generator ground with an ohmmeter you may find a direct connection.  Even if there is no DC connection (measured with your meter) there may be a capacitive connection which would do the same job at RF.

I wonder if Dr Stiffler is around to answer a question about his circuit #7 in figures 14, 15, &16?  I notice that there is of order 200mA (RMS) flowing through the earth lead.  This suggests strongly that power is flowing somewhere.  The question I would like to know is - is it flowing into the circuit from the outside, or out of the circuit from the ferrite core etc, or simply resonating back and forth (ie with power factor zero).

A simple measurement that would settle this question would be to simply show as a second trace on the CRO, the voltage on the aluminum pie can (which presumably couples quite well to the circuit via the backing plate etc).  The phase between any voltage appearing on the can and the current passing through the 1 ohm sensing resistor should tell us whether significant power was actually flowing, and in which direction.  It would also be important to know which end of the 1 ohm resistor was connected to the CRO ground for the measurement - as this should be made a common ground for both the voltage and current sense - as we would need to know whether to subtract the current sensing voltage from any voltage appearing on the pie can.  (I am sure you know Dr Stiffler how to keep the CRO grounds as short as possible to avoid inductive pickup - using the little earth rings near the probe tips is best and making sure the common earth point on the resistor is very close to the pie can connection).
