Selfcharging cap circuit from Larskro fake or real ?

[Groundloop]

Hi Groundloop.
well done with the circuit diagramm, but I believe, the LEDs 1 and 2
might be the wrong way around ?
As the Schottky diode as it is used this way normally blocks already the Back EMF
I wonder if the LEDs would not be reversed in the circuit to at least conduct some of the
BackEMF pulses back to the positive pole of the caps ?

Or are the LEDs only there to keep the voltage at the caps not going to high by
shunting current away, if  their treshold voltage is reached ?

Many thanks.

Regards, Stefan.

Stefan,

It is hard to tell what way the LEDs are connected.
I guess we have to wait until Larskro provide a circuit drawing.

Nikolai Zaev also worked with nonlinear capacitors that converted temperature to electricity.

I believe that second cap is a super cap, or memory cap as they are called sometimes in the surplus catalogs.  I have that exact same cap right here in my hand.  It is as Groundloop says: .47 F 5.5 volts.  I can light a couple of leds with it for a long time.  That is almost 1/2 farad at 5.5 volts so there is a good amount of energy there.  Using it in a JT type circuit will make it last a lot longer still.  This is the second super cap I had ever purchased after finding out that I could use them like a battery.  (I have obtained many more since then...some very large)

Not quite the "exact same". Your cap has both terminals on one side, as does mine of that style (mine are 1 F though.) Larskro's cap has one terminal on each end, I think.

I don't know if what he's showing is the same "capacitor recovery" effect I showed with the "TKBloomer" circuit, where the supercap's voltage is seen to be rising, while the LED is lit, even though no power is being supplied externally.

Or... you could build it and try the LEDs both ways.

Why can't the motor be replaced with a simple coil and the reed switch replaced with a mosfet or bjt ? If that is self running then almost any coil switching set up should be able to self run as well.

This was my immediate thought as well. However, nothing switches quite like a reed switch.

Maybe the black electrolytic capacitor is a very small battery in disguise. I've got some that look like that and I considered slipping a capacitor plastic cover on them to make them appear to be capacitors, which they would very much so appear to be with some capacitor plastic on them.

Or the loop on and loop off could be opposite to what we are led to believe.

Cheers

If it's faked in some blatant way like that, I'd be very disappointed. I hope it's really a spike-recycler. It might take a little while to test the energy budget to see if it's just fluffing up charge like some battery-powered circuits do without really changing the total energy. But I don't know if you can actually do that fluffing with a supercapacitor instead of a battery.
