Mysterious Resonant Circuit

CONCERNING CAP MARKINGS:

220J is 22pf

Using a one or two number marking, the number is directly in pf.

Using a three number marking, it is based upon the formula AB X 10^C in pf. In the case of a zero, then it is just AB.

For instance:

220J = 22pf
221J = 220pf
222J = 2200pf
etc....

103J would then be 10 X 10^3 pf, or 10,000pf or .01uf.
104J 100,000pf or .1uf

The end letter is the capacitors tolerance.

D = +/- 0.5 pf
F = +/- 1%
G = +/- 2%
H = +/- 3%
J = +/- 5%
K = +/- 10%
M = +/- 20%
P = +100% / -0%
Z = +80% / -20%

Now, some capacitors have a second number underneath the first, and it is voltage.

104J
50

This would then be a .1uf cap at 50v.

I hope this helps.

Hi EM,
please can you state the exact frequency,
where you get these OU results ?

Does it only happen at this one frequency ?

Please don?t change the toroid and the coils.

It might be a lucky coincidence, that your winding combination
has got you this.
Maybe the 4 coil windings exhibit some anti-Lenz characteristic ?

Better replicate the setup with exactly the same parts again and also try to build a third
bigger unit, to see, if you can scale up the effect in power.

Also, why do you put the 2 LC lowpassfilters filters in parallel with the battery, but not in front of the battery ?

Can you also use a real powersupply instead of a battery to power this circuit
or does the internal battery resistance play a role inside the circuit ?
What, if you put a 100 nF cap directly parallel with the battery together with a 100 uF electrolytic cap ?

Many thanks and looking forward to more tests.

Regards, Stefan.

Get another battery and attach a DC motor, or buzzer, or attack it to various parts of the current circuit.

Based on my research I have established it IS possible to pull in EM fields and motors and buzzers are ideal, it could very well be the air core coils that do the receiving.

If doing such can boost the output then you should be closer to your goal as energy does not have to be lost from the loose coupled source.

I don't know what EM intended with the bandpass filter circuits but they aren't supressing RF in the battery. They are shorting RF around the battery. Same final effect in the battery.
I think the most important function for these LC circuits is they are completing the RF circuit where the battery was breaking it.
If he uses a power supply I suggest the LC's stay connected. At their resonant frequency their impedance is near zero.

I think you will find he is using the coil and cap to get rid of the nasty noise which is across the battery, i am having the same problem, i have about 2 volts of crap across my battery, and it doesnt go by putting different cap across, he is trying to get a smooth dc across his battery because he can then be confident of the power consumption.
My rendition is running at about 22Mhz, but have not had much chance to refine cap values yet.
