Selfrunning cold electricity circuit from Dr.Stiffler

Okay, now also at my place the Google video is showing,

One more information about it.

The scope in the video was always connected directly across the
signal generator output, so you always see just this output there.

Of course I had connected also the scope ground to the
signal generator ground.

So you see the damping of the output wavefrom from this
choke and LED load going into the stainless steel mesh via this one
wire setup.

I had the camera on a tripod, so it would be not so shaky,
but sometimes it was then hard to film the right parts of the table,
when I wanted to film the whole scene.

Will get better next time.
Regards, Stefan.

@amigo

well done.

Try to put a ground cable or a big alufoil
or metal mesh against one pin of the LED
( does not matter which one)
then the LED will be much brighter at the right
resonance frequency.

@stefan

Thanks !

That's what I first tried, and it made it brighter, but I noticed I do not get any change now that I have the Al foil underneath it...

I have problems measuring with my grounded scope now the current coming from
the signal generator at a shunt.

Have to isolate the scope from the ground first and then try again.

Stay tuned for this.

@amigo,
when is your LED the brightest ?
With the alufoil below your experimentation board ?

Or with the alufoil just connected to one LED pin ?

Can you try to measure how much current flows from your
driver circuit via the one wire to your ferrite transformer  ?

So the main problem is with these circuits,
how do you design a very low power very fast rising square wave
or pulse generator ?

Would be interesting to see, if shorter positive pulses will
still give the same brightness if you change the duty cycle.

Regards, Stefan.

I have made a video, especially for that paranoid delusional freak who's name I won't mention and his followers, but everyone is welcome to watch it...it's educational !
