RESONANCE EFFECTS FOR EVERYONE TO SHARE

[gotoluc]

Sai Ram Luc,

My secret Christmas wish to the Universe was that I could be able to fully finance your important work...

Because for anyone to comment correctly you really need to give everyone a full "3D" picture of what is going on or we end up like the "4 blind men trying to describing the elephant"

If you are using AC - you really ought to be monitoring the current, voltage and most importantly POWER FACTOR at ALL times.
(perhaps you should come and borrow a scope that can do that for you?)

This will tell you and all of us what is really going on in all the coils at all times.

Cheers
Thane

Sai Ram Thane,

thank you for your offer to borrow one of your Power meters. I just tried it now with a cheap plug in power meter and the meter displays the SG consumes 11 watts just sitting there doing no work and when I connect the coil to the output of the SG the meter starts to flip back and forth from 11w to 12w and back to 11w. I don't remember if your power meters have a .00 resolution?   if not, there would be not much point to using it to get a real readings.  We also need to understand and consider that the effect gets better with higher voltage and my SG could only output 7 volts RMS max. at that point, so I would not be comfortable to evaluate the effect at this low of a voltage going through the coils.

Thane, I will be posting a video link to a Tesla experiment and I know you will recognize the one who is doing the demonstration but I ask you to not give out his name as he may want to stay anonymous and we should respect that. I have great respect for him to take the step forward to start sharing his experiments and that is the most important of all.

Thank you my friend and brother.

@gotoluc:
Yes, that is what I was trying to get across earlier. The signal generator driving the primary with a square wave, is like striking a gong. The secondary has its own resonant frequency, or wavelength, that may be approximated by taking the wire length as a quarter wavelength, then adjusting for various variables like capacitance, top load, etc. So your signal generator and capacitative coupling is acting like the HV power supply and spark gap of a Tesla coil system, and the air-core secondary is "ringing down" between driving pulses. If you can drive the primary directly at the secondary's ring frequency, you should get the most voltage amplification and greatest "range". The damped decay in the secondary's ring trace is related to the "Q" of the system. The better the "Q" the less decay in this ringdown trace.
I think.

You can determine the exact resonant frequency of your secondary, by looking at the output of the coil with the scope, through a 1-meg resistor. Drive the primary directly (or even just loop a turn or two of wire around) with a small signal from the SG (square waves work best). Hook the ground of the scope probe to the base of the secondary, and hook the probe to the 1-meg resistor, hook the resistor to the top of the secondary. Sweep the generator near the calculated frequency, and look for a peak on the scope trace==the output voltage of the coil will peak when you are driving the primary at the 1/4 wavelength resonant frequency.
Then, when you put power to a real primary using the SG amplifier or the H-bridge, this will be the frequency to start with.

Hi TinselKoala,

thanks for your reply and great information on finding the real frequency the secondary is resonating at. I was sweeping around yesterday and had found it was peaking at 2Mhz and wondered why it was not charging the cap but that would be because my primary is peaking at 625Khz.

I'll add more length to the secondary to tune it to the primary resonance and see what that does.

I'll post the finding

Thanks for sharing

Hi everyone,

here is a link to an excellent video demonstration of Tesla's work. I know this good man and I hope he can join us and share his great knowledge.

@everyone,

the video link I just posted is from Karl Palsness. It now looks like he doesn't mind that his name is shared since he has started a topic at the Energetic Forum.

Sorry Thane for asking you to not to mention his name but all I got from him was the video link and no instructions.
