Selfrunning cold electricity circuit from Dr.Stiffler

[SpongeDave]

one has to remember that the overall power is maybe at 0.8-1W. This is a fact, which is clearly achievable using one wire, conventional electric theory.

     Congrats, you have a crystal (light emitting) diode radio for a shortwave station in Mexico.
     Run it in a Faraday cage with no external wires and report back to me. ;-)

@All

Let me post some worst case figures for you to look over. My single coil, driven by a Colpitts Oscillator drawing 5mA into an impedance converter drawing 20mA from 12 volts.

12 x 2.5E-2 = 0.300 or 300 mW input.

Driving 75 LEDS in series with a forward drop each of 3.2 -3.8 volts with 4mA in the series chain. Lets use the low forward drop;

75 x 3.2 = 240 volts therefore 240 x 4E-3 = 0.960 or 960 mW

Do you all understand? and this is worst case.

Thanks for doing the test with the thin wire, but how much was thin ?
I have verified your scheme, you really have a set of LEDs fed in parallel, so the current should not be little. When you use a thin wire, can you measure the current with the oscilloscope ?
Is it possible do you tries with longer wire, at least 2/3 mt. and you do again the test.

Best regards,
Adriano

Friend! I enjoy the acronym. How is the family doing.
