Selfrunning cold electricity circuit from Dr.Stiffler

Have a look at this:

THIS VIDEO NOT EXIST !

Amazing !

I hope Dr. Stiffler will publish the exact circuit.

This afternoon I have finished a series of test with the Stiffer experiment. The basic experiment setup in based to the scheme "Thomas Oscillator". The figure called: "Experiment setup 4 - 800.jpg" look the scheme and my modify. The power system is an alimentator.
In this experiment I have wanted to use a LED for the comparison of the values of brightness. In other thread of this discussion had been introduced the problem to determine the real brightness of the LEDs. The human eye succeeds in distinguishing well the differences of brightness but not the absolute brightness, for this I have inserted a test LED regulated by a potenziometer (look the picture called "Experiment setup 3 - 800.jpg").
Regulating in opportune way the potenziometer the two LEDs will have the same brightness, at this point it is possible to read the consumption of the LED of comparison (Always powered with the same tension of the apparatus) with that of the whole apparatus.
Tolerance should be of + /- 20%, but I don't consider the certain experiment if the values of consumption of the apparatus don't differ than at least the 50% of the calculated ones using the LED of comparison.
For example, look the "Experiment Setup 1- 800.jpg":
The left multimeter report the absorb current of apparatus, value is 153 mA
The rigth multimeter report the absorb current of comparison LED 6,5 mA
The LED array is composed by 50 LED (linked in series)
Every LED absorb 153/50 = 3 mA vi s value is less then 6,5 mA of comparison LED.
In other tests I have noticed that for 160 MA of consumption of the apparatus (3,2 mA for LED), the LED of comparison report 8,5 mA, equal to almost 2,5 times.

Causes the poor Italian postal service, I have not succeeded in getting from USA the spool used by Stiffer, I have decided to build it, with the data brought in the figure: called "Experiment setup 3 - 800.jpg"
The tension in exit is inferior and this surely makes less quality results, but it shows that it is possible to build interesting varyanting, using other type of material.

Best regards

comments on circuit:

I have been wrong before and I could be wrong again. But, the circuit performance seems to depend on just where the parasitic capacitance is coupled into it. If it is coupled as in fig.1 then there is rectified RF going through LED diodes. If it is coupled as in fig.2 then there is DC going through he LED diodes. In both cases the capacitor charges to the peak to peak voltage across the two paths. Since Dr. Stiffler has DC on his LED diodes, he would seem to have a circuit performing as in fig. 2. Parasitic capacitance exists between any two points, so it is not a matter of where it exits but rather how large the capacitance is. RF current will flow most where the capacitance is largest. To duplicate his circuit perhaps extra parasitic capacitance should be added at the ends of the capacitor.

Note, rectified RF looks like DC on a volt meter so a scope is needed to see it. Another way to tell is to insert a series capacitor, DC will not flow through the capacitor but rectified RF will. Reverse biasing a diode will turn it into a capacitor but the capacitance may not be large enough to pass much current unless the frequency is very high.

And one super stupid question: how can I find the uH of a coil with regular tools such as multimeter, osciloscope?

You can build one pretty cheap using a PIC16F84A, here's a schematic.

For some reason fig. 1 did not get posted.
