Magnetic Resonance Devices based on Don Smith Concepts

[Yucca]

I have noticed a peculiar behaviour, perhaps someone can explain this asymetry?

OK, again operating with the secondary ends connected across bridge. gap distance kept the same in each case. Centre tap ignored. I was counting gapfires per second (gf/s) using a 20 second sample time:

==============================
When all of the secondary is ungrounded:
0.80 gf/s

When I ground the base of the secondary:
5.20 gf/s

When I ground the top of the secondary:
2.90 gf/s

==============================
then I reversed polarity of the primary coil and saw this:

When all of the secondary is ungrounded:
2.10 gf/s

When I ground the base of the secondary:
5.80 gf/s

When I ground the top of the secondary:
3.50 gf/s
==============================

These results are strange, why does grounding the base of the secondary give much higher output energy regardless of the polarity of the primary excitation?

Again I must also say again, the gf/s increases from a slow rate to a higher stable rate over the course of maybe 20 seconds. And then if you leave the device off for a few minutes you can see the slow rate on startup again, it really is weird, if you turn it off for just 10s then it starts up fast again. Could this be some aetheric inertial behaviour perhaps?

But always when I switch back and forth between top and bottom grounding I see a large difference in performance.

edit:
This is a radio circuit really, so maybe the tuning changes lots depending on slight adjustments, it's certainly got some weird behaviour and power outputs can vary greatly.

wow those pictures are handy did i miss some information posted somewhere?

OK this is making more sense now, so we know there's a cap on one side of the secondary, so we tune the primary and the secondary also.

now we see  a cap across the top half of the secondary and i cannot see a wire connecting the bottom half so i would guess it also is linked back to the top as per the diagram, so both halfs are indeed in parallel.

It is also interesting to see the construction of the coil, he uses 2 different sizes of tube, the inner has the primary wound on it, and he uses  2 seperate half length tubes, one for each half of the secondary and they each push onto the primary tube, we can see 2 wires connecting to the connecting block in the middle tap.

Now i would imagine the grey boxes are high voltage caps, although i would have expected to see diodes in there place, not that familiar with real high voltage components so i could be wrong, so wheres the diodes.

@Yucca
very interesting with the gf/s
Not sure what it means sorry.

i have now finished building my HV psu
I already have a loptx based supply i built some time ago for lifter tests.

but have been bringing together stuff i built for the TPU.
My new psu uses a blocking monostable driven from a signal generator followed by a 5 stage multiplier, i wasn't sure if i would get the current to produce a good enough spark but it seems to be ok i think.

Here's a video

Although the mike doesn't pick up much of the spark sound it is quiet loud.
The current draw is low about 13ma at 90v supply voltage and the rails are clean.

@Yucca:
Good to have some epiric data! Nice one.
In the TPU the orientation of the coil was important.
Upside down it did not work at all.
Maybe the orientation of the coil in your device is also important for its function in a similar way.

@Peter:
Here is a better resolution one: http://www.yousendit.com/download/YkxKOGNkWkJWRDljR0E9PQ

The diodes are there, in front of the HV cap positive terminal rail.
Actually the wiring of the secondary is quite remarkable.
The outer ends are connected together to the high pressure cable (plus line to the cap)
via the rectifier diodes.
And the center tap is connected to the minus line to the cap.
This is different than in Smith´s pdf diagram.
I have drawn a schematic of how it might look like, but i don´t know what these two components are in the top half of the secondary. Probably also caps ?!
Also that feedback unit is not clear to me in its functionality.

The OD of the primary is 2" and the OD of the secondary is 3"
The primary was supposed to be slidable inside of the secondary to tune the device,
but Smith was already tuned even without sliding just by adding two caps.

The remarkable thing about the whole device is that it seems to work with unidirectional impulses on the primary and the secondary with (nearly) no negative amplitude.

Oh man thank you for that image what a difference a good photo makes.

Yes i see the problem identifying the 2 little grey components, they look like high value plastic molded resistors to me, i have never known small caps to be coloured grey before but i guess anything is possible.

That is also silver plated copper wire for the secondary not tinned.

The good news is now all i need to buy is 1 very high voltage high current diode as the output rectifier.

The box you have a question mark over on the output leg is an inductor.

I wonder how many of these components can still be bought i bet they turn up from time to time on ebay.

Cheers,
Peter
