No, it isn't. It is Patrick Kelly's explanation on page 38

Thanks for pointing that out, I didn't realize there was a section in Chapter 5 relating to Dons device in there. I worked through it by experimenting with some of his work from the chapter 3 write up.

More reading to do as it appears, not enough time in a day for everything I'd like to do....

Device on photo is conceptual device and I don't think it ever worked. It represents basic idea of briefcase device, not a sized replica. Don mentioned that briefcase device is a solid state device.
I don't know how does it actually work, but I'll try to figure it out. Because I do believe the device is real.
The next thing I will try to do is to go solid state. So if you have any ideas on how to do it I'll be glad to discuss it with you.

Since the table top unit was never demonstrated as a working unit you have to treat it as a non working unit. The suitcase demonstration, since it was never opened, has to be considered a possible fake no matter how much we want to believe it worked. To replicate a device that was known never to work - in public anyway, seems self defeating... why replicate a non working unit as the results are known. Either way, some of dons theory's are workable, we can take it from there and work through the obvious.

If you look at the second portion of his "simple device", the L2 and IT are connected directly together - short circuit senario. This converts all the voltage to current so we are working in the realm of pulsed electromagnatism, moving current from the resonant circuit to the output IT.

The trick is in finding resonance in a loaded coil, and not disturbing or loading the primary resonant circuit. The output becomes "new energy" and out of phase with the input thus it's not loading the input circuit.

This is simply my take on what he was attempting to accomplish...

@ Amigo

I have also ordered the same NST amigo! Nothing happens huh? keep at it and try stuff!

@Mrulye

basically what you propose is a old-fashion tesla coil setup that has the spark-gap in series to LC1 circuit. As i am reading also from Tesla's colorado spring notes, it is necessary for raising the Q to eliminate the spark-gap from the LC circuit. Several schemas are proposed in the book.

But in Don case, the outline is pretty much self explained. The arrestor does not isolate coil from caps. Actually the coil-caps are tightly screwed together!

Secondly, DOn's receiving coil, has only 1 cap (fom resonating) the L2C2 part1. The second part has nothing (only diodes).

In any case, if we are not capable to resonate at least a part of the circuit to tremendous resonance (say 3Kv at 10 amps) then our devices do not have a chance.
...

The most optimistic scenario is that Don's device is a non functionable but shows the way to go. I should mention that when made the Tesla conference demonstration with the suitcase, he claimed is a scaled down version of the device examined, yet resisted fiercely at opening it.

So, we can safely conclude that the table-top device it is not the whole story. In my oppinion we should abandon listening to every one may he be Don or Kapanadze and focus to the pure light of this Technology that is Nikola Tesla.
Anyway, they use his name and attribute their inventions to him, yet refuse to discolse anything of value.

[mlurye]

It's the way I connected it.

[amigo]

mlurye,

Would you be more clear, please? Move it where?

That schematic is basically drawn on what's visible on the high quality photos of the tabletop device.

If that configuration is wrong, then obviously the circuit does not work and it never did work and DS is full of ****.

Further more, I have just gotten a 9.5kV LowGlow neon transformer, used on cars for decorative lighting. It needs 12-14VDC so I feed it that through a SLA battery. Nothing else is changed in the circuit, as per the photos.

And yet NOTHING happens. My scope probe picks up nothing to write back home, just like with the previous test using much lower voltage (1.5kV).

So what gives?

I'll ask everyone again, whoever might know and understands: what is the purpose and point of those two diodes on the NST side? Why are we rectifying into DC, not to mention the siginificant voltage drop on the diodes in the process, etc?

[mlurye]

amigo,
I don't think it's possible to make this schema work with spark arrestor.
But if you'll move one end of capacitor on other side of arrestor then it will work.

[amigo]

amigo,
It's all depends on how you are planning to build the device.
Can you show the schema you are using to build it?

Basically what the tabletop device is. Baroutologos posted a schematic of the primary circuit couple of pages back:

http://www.energeticforum.com/attachments/renewable-energy/4636d1263817910-donald-l-smith-table_device_concept.jpg

I have only been experimenting with the primary stage, even though I wound a secondary already, I did not split it mid-point, might make another one.

I want to see what the primary does first as this configuration that DS showed in the tabletop device makes no sense to me, especially rectifying the NST output into DC voltage.

We need to somehow find out what was the value of the spark arrestor he used. That is if that tabletop device ever worked to begin with...

[mlurye]

From my limited testing so far, I did not see the spark arrestor doing anything whatsoever, as per DS configuration.

Further more, the voltage drop over those diodes in L1 circuit appears to be significant. For the sake of argument, I replaced the MW oven diodes with standard 1N4007s (two each to get 2kV) and the voltage on L1 picked up by the scope probe went up but still nothing to write home, ie. could not excite the arrestor.

Why exactly do we need those diodes as I am not clear on their purpose, beside rectifying the NST output which provides us with exactly what? If there's no path to the ground via the arrestor, we aren't getting any sufficient oscillations in the L1 circuit, no?

Also, I do not believe that NST voltage matters, mlurye. If we are to believe this is all about amplification through resonance, then any startup voltage could be used, with a properly chosen arrestor.

I think in my next order from digi-key, I'll get a bunch of arrestors with different values and be able to test the effect.

In any case, I still think we should not be worried about, or bothering with, specific NST values or models, or trying to match its resonant frequency. It is there just as a source of HV not the source of oscillations, they are rectified by the diodes...

3kV NST with mid point works with 350V spark arrestor.

Hey, you have built a replication? Cool! Can you share any photo?
bear in mind that, no-ones assures you that your built is Don's built (in case he does not hide any core or anything).

By the way, your findings are very reasonable i would say. Well within my poor estimates.

Can i ask few questions that are in my mind? What Q you enjoy on the primary? (meaning current magnification at what voltage range?)

Are your collection diodes ok at those frequencies?
any attempt to tap anything?

Have you came to any conclusion why he uses that particular L2 configuration from a practical point of view?

I built it, but it doesn't work yet. I don't have correct NST(I have 3kV with mid point) and may be it's part of my problem. Having hard time to tune it up.

I don't think that Don is hiding anything. All information about device available on youtube.

It's easy to build it, it's hard to tune it up.

Here are diodes I have 4x1A10kV High Voltage Diode HV Rectifier Tesla coil Ham - eBay (item 360227896137 end time Jan-27-10 03:13:57 PST).

@baroutologos
1 more time. Don's tabletop device resonates at 200kHz (I built it and tested resonant frequencies for L1 and L2.1, it is exact 200kHZ for both)
L2 has 18 turns each.
@bedinimotor
I WOULD NOT advice you to use MOT, it has very high current draw comparing to NSTs.
