Magnetic Resonance Devices based on Don Smith Concepts

[Yucca]

I now understand how he closes the loop and powers a load at the same time.

The 2 coil inductor after the secondary caps is used as a 1:1 air transformer.

He is using a pulsed load probably much like the inverter on the diagram that Yucca is building with the 2 transistors, which draws pulsed current from the secondary caps, in the positive line from the secondary caps and his pulsed inverter load is the inductor which has the pulsed load current flowing through it, this induces a fluctuating RF magnetic field which is then coupled to the second coil on that inductor which is then rectified smoothed and fed back to the 12 volt gelcel.

So the whole circuit is recharging while powering the main load, the more power that is drawn from the main load the more power is put back into the gelcell to drive the primary inverter and neon transformer.

I am going to guess that 1 of the coils on that final inductor slides closer to the primary to adjust the coupling and hence recharge power that feeds back to the gelcell.

This is very clever and is probably in place of the matching resisitor he uses in Yucca's build diagram which matches the final output inverter, but a resistor is lost energy to heat, but using this inductor instead of waste heat we get useful recharge current instead.

Peter, Interesting thought, it's a clever idea indeed. Thinking on that further maybe if the inverter switching were phase locked to the secondary coils natural resonance then oscillations could really be pumped? One can get to 20MHz easily with cheap N FETs.

Maybe the phase locking could be achieved with a small low ohm shunt in the inverter input line feeding a bandpass filter. Duty cycle could then be accomplished by turning the FET on at set phase angle and then turning off after a variable time.

The ideal phase angle to switch on I'm not sure.

I need to think about winding a two part secondary like yours. I need more wire and will get some grommet strip. First I'll try tuning what I've got for max efficiency.

@Yucca & Peterae

What do you think of this little test!!!  It is kinda like a small tesla hairpin circuit.  The interesting thing about it is that it is lighting an led on a different JT circuit...no contact.  Also you can see voltage reading off my DMM that's connected to my JT!  What are your thoughts on this?

Nice experiment, that tiny HV module is very sweet, I want one! The spark gap's a beauty too!

The tiny red hairpin wire must be going at a hell of a lick lol, I'm suprised the blue base caps can keep up.

So the seperate JT is unpowered and in the vicinity and is lighting? Do you notice your hairpin neon dimming if you bring the JT coil very close to the hairpin?

Do you have another JT to put close by and see if power is shared or do they both light just as bright?

edit:
Do you have a scope available?

@ stprue

Does the neon light if you remove the red wire loop?

@ stprue

I like your spark gap. Did you make it?

[Peterae]

stprue

great hairpin build, you must be having real fun with that little baby 

Just wondering how far away the JT lights the led.

Nice HV psu are you willing to share details on this as it could be very handy for driving the primary on Don's coils.

Yucca

The grommet strip certainly spaces the wire well, a tip is to make sure you push something like a ruler down it's length before gluing just to make it look nice and straight.

The problem i have with my theory on the 1:1 coil coupling is that he says he uses 60Hz for the final load conversion to drive presumably household devices, and i wouldn't imagine the 1:1 coil would work at such low freq's

It looks like he uses crisscrossed litz wire on that final inductor
