Selfrunning cold electricity circuit from Dr.Stiffler

Did you all see the Ossi Callanan circuit on :

?

Wow
this is pretty bright.
How much power goes into there from the batteries ?

I wonder, why in :

http://67.76.235.52/drstiffler/buildup.asp

the voltage is smallest at the resonance frequency ?
Normally, when you look at firgure 9 circuit diagramm
the voltage must be the highest at resonance,
cause the series LC circuit has the lowest resistance
at resonance and then the 50 ohm resistor gets the
highest voltage.

Maybe he has just measured across the LC circuit ?

78ma from the 12V battery. Only had 67 LEDs. Estimate the circuit could light up to 200 LEDs.

I'm sure the doc will correct me if I'm wrong, but I believe that L2 and L3 form a resonant transformer, like a telsa coil, and the "Stiffler core" resonance frequency is the frequency at which the oscillating current in L3 is maximal.  The high-voltage oscillations in L3 inductively couple back to L2, where they oppose the generator signal, causing less power to be drawn from the generator and dumped into the load resistor.

Wow that's impressive, 67 LEDs look pretty blinding, what happens when you put 200?

Hi Harti
The reason the voltage drops on the test circuit at self resonance is that the measurement circuit  is in SERIES with the coil.  You are correct that the AC voltage across the coil is at maximum, but it is out of phase with the generator, so in this series testing circuit,  you get maximum cancellation at the coils self resonant frequency, and thus the lowest output to the scope. At self-resonance, the capacitor in the LC circuit  doesn't exist physically, but is mostly made up of stray capacitance between the wires in the coil itself.  The reason Ron is measuring this way, is to prevent placing any additional stray capacitance (from scope or measuring equipment) across the coil which would alter the resonant frequency being measured, and cause an incorrect frequency reading.  Dr. Stiffler is obviously familiar with RF measurement techniques. So far, the more of his work I see, the more impressed I am.



PS
Ossi Callanan's circuit does look bright, the circuit is being fed by 12 volts, so the input signal to the coil is probably a higher voltage than the typical output of a signal generator used in some of the other circuits.  The real question is: What is the RATIO between true RMS input power  and output power?
