Selfrunning cold electricity circuit from Dr.Stiffler

[amigo]

In other news, I have fixed my Wavetek 191 so it fully works now with all waveforms. Prior owners have done a botchy job in replacing the BNC female connector and there was no contact.

My resonance are found around 11MHz and 19MHz, will find out exactly soon. I still do not see my neon light up...humbug.

EDIT: resonances at ~3.01MHz and ~9.51MHz

@Mark
Thanks again. My observations were only with the signal generator attached. If the scope is connected the OP seems quite strong. The Blue LED turns on quite nicely then.


@DrStiffler,
I have a batch of the 680uH cores and as they are the critical part of this investigation I wanted to clear up a few points.

1- The number turns you specified at 9 turns but I count 11 in the picture.
2- You did say that the sense of the L3 should be the same as the L2 core. Please can you verify that. Either my L2 cores are wound the wrong way by the manufacturer or the  image may be mirrored somehow.
3- You use a symbol for the L2-L3 combination which indicates 3 different windings. L2, as arrives from the supplier only has one winding. Am I missing something?

regards

AM

Its still where it was put?

Thank you Ron for posting the link. Must have been a glitch in my IE
I've added it straight to my favourites folder.

Fascinating stuff! Eagerly awaiting the next "Chapter"!

Okay, hereare for now already 4 pictures of my new tests.

I just rewired the 10 turn coil around the Litzwire coil into the other
direction and guess what, I for the first time saw
now the neon bulb glowing really bright,
but only, when I don?t use the core...
Hmm...

Check this out.
The winding direction of the 2 coils seems to be very important !

I also recorded 2 videos while playing with the setup
and you can see, how I suddenly stumbled onto the
neon bulb glowing brightly for the first time.
But you will also see, that the LED still is brighter,
just without my cores...just the coils alone...

I have toconvert now the videos from the camera format
to amore commom format.
Stay tuned.
Maybe I could buy from Ron a verified core, so
I could really test it with the amplification...

[hartiberlin]

P.S.: My AM Litzwire coil has indeed 2 coils on there, one larger turn coil
and one smaller turn coil,cause it also was used for longwave in the
radio I got it from..

So you see 4 litzwires coming from the coil plus 2 wires from the 10 turn coil around it.

The thing at the right side after the big red 470 pF  is the 2.2uH coil,
it looks like a resistor but is actually a coil.

I had modified the 40106 oscillator circuit this way, that I have now
only 3 hex-inverter drivers in parallel and am using
2 inverters after the single oscillator inverter to
"sharpen and fasten" the waveform.

Maybe as the circuit seems not to need much current,
I should only use one inverter as the output driver and
use all the others to fasten the waveform ?
I will try this later...

The scope you see shows about 12 Mhz waveform.
I used in this test a powersupply with 12 Volts DC
and the amplifier on the scope is set to 5 volts /div,so
the AC amplitude was about 8  to 9 Volts peak to peak.
It was measured at the last driver output directly.
the scope ground was connected to the circuit ground.
The scope was grounded, but I did not need now the
metal mesh what I normally used at one LED pin.

The ground line of the scope was directly in the center of the scope screen.
If you have questions please let me know,but maybe you will
just wait for the 2 videos.
Regards, Stefan.
