I had something interesting happen yesterday.
first for a bit of background,

1- I have a dozen stubblefield generators. These are induction coils. Some of mine have secondaries. I made various sizes and materials and cores etc.
2- I have been playing around with a joule thief for 6 months and using the secondaries wound from them to produce various effects like lighting many leds or fluoro tubes for hours and pushing their design to see what they will do.
From before the start of this thread, I have thought the joule thief with secondary had the potential to replace the sparking induction coil.


So, yesterday, inspired by this thread and the thoughts of radiance and tesla's uncharted circuits, I put a few of my things together.
I had other plans but this is what happened:

I connected the secondary of a step-up stubblefield generator to my scope probes, and I turned on the scope.
Then I put the battery to the compound joule thief.

The stubblefield coil was still not connected to the joule thief, and,
I got a wave.
It was only about 100mv, but it was all radiant, and I was not even touching any of it to ground it.
The airborn oscillations of the area around the joule thief were enough to set the stubblefield generator in motion.

I want to encourage anybody to keep up with this work here. It has a lot of merit and will lead us to our goals.

One of mine is quiet, so I am thrilled to see 100mV from one transistor passing radiant energy through the air.

For me the next thing is to match these elements. Pulling things out of a shoebox and seeing them work is only the proof of concept. Now, the real work begins.
But, now I KNOW it IS possible to do this circuit with a transistor.

I made 2 videos to show this.
Each is 2 1/2 minutes long.
If you would like to watch them, here are the links:

Jeanna.
You can increase the output even more by using an APM-circuit, i made a similar experiment some time ago: http://www.youtube.com/watch?v=YD_QKaaF3ik (Picked up energy from the ignition coil)
It is helpful to see that the signal contains various rings/radiant spikes thanks to your oscilloscope shots which visualizes that nicely !
I had to rectify the signal to charge anything, which is weird because the radiant content of the signal should have potentially charged the battery.


Replacing the spark gap with solid state components is desirable and you hopefully will find a way for certain applications. Can you oscilloscope do fourier analysis? You could then find out about the HF content in comparison to a spark gap.

Hi Jeanna,
really nice work.
COuld you please post a circuit diagram of your JT circuit ?

What does it do, if you ground the JT and / or the STubblefield coil
with one end to your sink or heating pipe ?
Will there be more induction ?

Please try to work on the resonance frequency of your
STubblefield coil with the drive frequency of your JT.

Many thanks.

Regards, Stefan.

Hi Mark ,
Thanks.

and Stephan,

There are many pages of progress on these things you are asking for. I will start by providing links to the thread I started.
You can read the whole thread, of course, but if you want to skip around, please be sure you stop and look at these 3 posts.
They describe the evolution of this circuit drawing.
I realized a while back that the way Tesla drew his circuit has wide implications, and I want to be free to see them. So, I have changed my drawing. And it is still evolving.

I have been checking the frequency of the JT all along.
The one I was using in the video has a frequency of 50KHz sometimes, and 208KHz sometimes. This is being measured across the wires of the secondary. When there are 2 different secondaries, and multiple inductors there is a lot going on.
I have much more to look at and I will continue to report it.

What happened yesterday was something different.
I need to do a much bigger study now. (this is very exciting for me)
I believe, today, that the NS (Nathan Stubblefield) coil is a receiver.
I am not prepared to say much more. I have many ideas etc, but I don't want to speculate because there is much to find out.

So, for now,
here are the 3 pages:

http://www.overunity.com/index.php?topic=7617.msg187473#msg187473

And, here is the most recent drawing of the JT circuit because it is the closest to what I used in the videos.
Later, I will add a full drawing of this plus the NS coil and the scope.

Oh, the scope probes are connected to the 2 wires of the secondary of the NS coil and that NS coil is NOT touching the JT circuit. And, I am not touching it either!

Thank you,

jeanna

EDIT

I just changed the picture and schematic to show more exactly the circuit and radiant connection that is on the videos.

I took a moment to remove 2 of the extra inductors and one extra led. With those changes there may be a change or not.
If there is a change there is more of a ring somewhere because the frequency is now over 620KHz. but the ring is more frantic.

Therefore,
I believe this drawing is a fair representation of what you saw on the videos.

thanks,

jeanna

@Stefan: In the video you posted there is the same tone at an enormous volume level audible like in the glass-container Kapanadze video. It has its strongest peak at 100 Hz.
I wonder if that is just nothing special in high power electrical devices. I think in big industrial plants in the generator rooms there can be such noise level, but i am not sure.

Here is again the 3 KWatts Kapanadze video which was earlier removed.
For easier viewing I am directly putting it here into the webpage:
