Hi Itsu,

To check the correct tuning of the toroidal tank, you could use say a 2-3 turn loose coupling coil wound on the toroid to monitor the amplitude on the oscilloscope when tuning the trimmer capacitor for maximum, this way you can remove the probe self capacitance from the tank and the tuning can be correct also for the collector-emitter waveform test.

I suspect when the 5 kOhm trimmer pot has a certain value other than full zero Ohm, the voltage drop across it changes hence the transistor matching to the tank (operational point) also changes when the loading effect of L3 appears at the collector as you tune L3 to resonance, this may cause what you find.  You may wish to use say only 5 - 7 V supply instead of the 12 V battery for a test to see whether this strange behavior develops then  (no 5 kOhm or just short circuit it).

Regarding the brigthness getting less when you tune L3 to 13.56 MHz from its own frequency of 15 MHz may indicate the ferrite is already a bit lossy at that frequency? (unless you know its specifications but this is minor issue at present)

Thanks for your kindness.

erfandl and All-----I was able to get this 'Crystal Circuit Exciter' to stay running at 20 volts (the voltage Dr. Stiffler used on his signal generator experiments).  The led array I am using came on super bright.  At that brightness be careful about looking directly at it.  I saw spots after doing this experiment.  Here is the short video of this thing at 20v.  The camera dimmed the light appearance down.  It is much brighter than it appears here.

PS---Slider I just ordered one of those voltage AND amperage meters off EBay.  We need to know the wattage or this experiment is somewhat meaningless.  The field 'excitation' messes with the electronic meters though and I really don't trust them.  Measuring the voltage drop across a resistor is a better way.  I will say this ---- That little MPSA06 didn't blow up producing a huge amount of light.  Interesting.
thanks lidmotor.OK I using an plastic part removed from LED light to protecting eyes

All----I finally got my cheap function generator in the mail and got it to do a true replication of Dr. Stiffler's experiment.  The
Wiper Coil' I made was critical in getting this to work at 13MHz.  This effect does work at other frequencies depending on what coil you choose.

----Lidmotor

As I understand, the claim of Dr. Stiffler is that at 13,65 MHz some energy is sucked from the environment.

Looking at Lidmotors function generator test I make the following calculation:

A function generator usually is able to give a 2 Watt signal (10 Vpp through a 50 Ohm load --> 0.2 Ampere --> 2 Watt).

Lidmotor uses "an open circuit load" at which a function generator usually allows 20 Vpp. But also with an "open circuit load" it will not provide more than 2 Watt.

The calculated 2 Watt seem to be about right to produce the demonstrated LED brightness in Lidmotor's video.

One will have to look at the specs of Lidmotor's function generator to make a better calculation (look at the "amplitude characteristics" in the manual).

With an oscilloscope one could measure the true rms Voltage over a 50 Ohm resistor in series with the function generator output and also the phase angle, which would allow a calculation of the power fed to the coil. But will it work with a 50 Ohm resistor between the function generator output and the coil? If it does work one knows at least an upper bound of the energy going into the coil, which would be 2 Watt (or 4 Watt if one believes that the function generator can provide 4 Watt at 20 Vpp with an open circuit load). One could increase the series resistor to a 100 Ohm or even 1 K Ohm in order to arrive at lower upper bounds.

Have someone looked into Stifflers "spatial resonant frequency" and how that can play into better ing performance?

Dear Conrad,

Would like to notice that 10 Vpp has an RMS value of 10/2.82 = 3.54 V and this dissipates  P=3.542/50= 0.25 W in a 50 Ohm resistor.   Your calculation: (10 Vpp through a 50 Ohm load --> 0.2 Ampere --> 2 Watt)
would be correct if you wrote or used 10 V RMS and not 10 Vpp, ok?  AND this calculation is valid for a single 50 Ohm resistor across which there is 3.54 Vrms voltage, ok?  For s generator case, see this:

Regarding the function generator, it surely has a 50 Ohm internal resistance across which the specified max 20 Vpp appears BUT this is an unloaded case. And notice that 20 Vpp has about  7 V RMS value.  If someone connects a 50 Ohm resistor across this generator output, the 20 Vpp becomes 10 Vpp only, hence 3.54 V RMS of course and dissipation in the attached 50 Ohm is 3.542 V/50=12.53/50 = 0.25 W  (and 0.25 W is dissipated in the internal resistance of the generator too). 

If a 50 Ohm generator has 20 V RMS across its output (i.e. 56.4 Vpp) and you load it down with 50 Ohm resistor, the dissipation in this resistor will be 2 W.  This is because the 20 V RMS becomes 10 V RMS across the output hence across the resistor you attached   (102V/50 = 2 W).

I agree with the rest of your post.

Thank you Gyula!

Attached please find a revised estimate of an upper bound for the output energy from the function generator in Lidmotor's test.

It remains to estimate the energy dissipated in (coil  +  AV-plug  +  LEDs). But if it works with a 1 K external resistor R the output energy from the function generator would be less than 0,05 Watt which is for sure less than the LEDs need to shine brightly (49/1050 = about 0,05).

If the function generator test works with a 1 K Ohm external resistor, OU (or energy from the environment) is very likely. I am still very engaged in playing with stepper motors and gyroscopes, therefore I do not want to go into Stiffler-stuff. But Lidmotor could easily try some external resistors in his function generator tests.

Greetings, Conrad

Hi Conrad,
Yes, that is okay now. 

By the way, I believe this is the generator (FeelTech FY3200 series) Lidmotor uses and here is a good review on the generator
https://www.youtube.com/watch?v=EZ-i6lOTT9k
and the user manual is here:
https://img.banggood.com/file/products/20170423222303FY3200S%20Series.pdf

A notice is needed when using say a 1 kOhm resistor in series with the output of a generator: at 13-14 MHz frequencies, the quality of a resistor does count because a 1 K resistor is simply not a 1 k resistor any more but can be less due to the combined effects of its own parasitic components like mainly self capacitance and inductance which may gradually shunt the resistor.  Carbon and maybe film resistor types or so called inductance-free resistors should be used when meaningful power measurements are to be made around 13.5 MHz.

Hi Lidmotor,

Thanks for showing the test with your nice generator at a different frequency than 13.56 MHz. I suspected such setup may give similar results at other frequencies too, see my opinion on this here https://overunity.com/17249/dr-ronald-stiffler-sec-technology/msg522662/#msg522662  and here https://overunity.com/17249/dr-ronald-stiffler-sec-technology/msg522415/#msg522415 

These results do not rule out the views and findings Dr Stiffler holds or maintains on this setup of course, especially his finding that the P-N junction of LEDs can be excited by RF fields via a metal plate placed very closely behind them so that the junctions are capacitively excited. And the LEDs need to be connected in series and their circuit should be closed by two diodes to let current flow happen.

Gyula,

initial test shows that removing the probe from the toroid output and changing it to a 2 turn loose
coupling coil, the trimmer cap needs to be full (23pF) to show some oscillations.
Connecting a second probe to the collector/emitter stops the oscillations.

So think i need to have some more capacitance in the tank to work without the probe attached.

Anyway, reconnecting the probe to the toroid output and using the 2th probe across collector/emitter
shows the below signals:

(Blue is the collector/emitter signal, yellow again the toroid output).


More later,  itsu

Hi Itsu,
Unfortunately, the probe capacitance can affect the resonant frequency of the tank, though in a smaller way because the collector is tied to the tap and the emitter AC wise also connects to the positive rail via the internal impedance of the supply and any filter cap across the supply rails.  But this probe issue can be fine tuned by trial and error.
Thanks for the collector waveform. I think it will still change a little when the tank has the correct resonant frequency. I indicated the distance between the zero and the minimum collector voltage, it is about 2.5 V.

Thanks Gyula,

i will try a bigger variable cap and use a L3 coil (with leds) that resonates around 13.56MHz.

Question about the 100nF cap, i thought it will be included in the L3 / leds series resonance (pulling it down greatly), but it seems to have little influence.
Does this mean that there is no series resonance in play (L3 via capacitance to the leds)?

Anyway, here the diagram as i now have it running.

The 100 nF can influence resonance at 13.56 MHz only very very little, it is practically an AC short circuit.
I will think on the mutual influence between the tank and L3, both are a parallel resonant circuit connected in
series via the stray caps or fields.     Gyula

Gyula and Conrad ----Thanks for the feedback on that function generator I am using.  So I guess it gives out only about 1 watt.  Not much to play with but that is the whole point.  The crystal circuits we are building allow for increased power and the question is whether or not there is a gain.  It is an interesting study either way.

Mikrovolt-- I thought about a filter add on all last night.  Dr. Stiffler usually had one in his circuits.  I have always been sloppy in my work and left them off but in this study there might be a real need for one.  If there is a true gain then fine tuning might the difference in seeing it or not.  Just guessing.
