Magnetic Resonance Devices based on Don Smith Concepts

@Yucca

Nice build

Good luck for tonights tests.

@xenomorphlabs

It will be quiet interesting to get some hands on with his setup, hopefully we should be able to answer some of these questions.

Does anyone know what approx resonant frequency we are aiming for.

I tried to do some guesstimates by measuring the dimensions of the coil and if he used 0.2uF 4kv caps again then it came out at 405Khz

The coil came out at 0.77178uH

I want to double check these figures when i get some time, as in the doc he mentions 408Mhz

I have guestimated similar numbers, so i can confirm it !

One thing i am sure of, it is not a specific frequency that he is aiming for like suggested by some people who favour magic frequencies.
He stated that he just wants resonance and sticks as many caps on both sides as needed to achieve it.

As for his docs he mentions 200 Mhz too, but i am sure that is for different devices.
And for that the coils would have to be smaller i believe.
Except he considered some RF mysterious phenomenon coming from the spark gap only like Tesla observed too hehe.

Thats good it gives me something to aim for.

@Yucca what are you going to use for your spark gap.

@peterae, thoriated tungsten rods 1.2mm diameter, ends ground perfectly flat.

OK guys, I fired it up quickly when I grabbed a few mins, proper testing is yet to come.

I tried earthing to my house wiring earth and 2 computers rebooted in the house . So I need dedicated earth connection in the garden for this.

This is running with the secondary free floating, no forced half wave.

I mention in the video that the higher frequency component is due to the flyback, but having looked at the trace some more I now think it is related to the aircoils instead because it appears to be the first harmonic perfectly phased with the fundamental.

here's the vid, apologies for grainy quality, it's an old digital camera in movie mode:

edit:
The gaps are both set at about 0.5mm and both have 2000pF over them.

One thing I´ve noticed when its been powered off for some minutes and its then started: upon starting the output gapfire frequency takes quite a few seconds to build to a higher and stable running frequency, quite weird!

Nice set-up!  Keep it up
