Donald L Smith

[wrtner]

wrtner,
I am still a bit confused on that part. My meter is showing that the plasma globe is running around 18khz. Should i be seeking 1/4 wave of that frequency?

As I understand it, the circuit should be designed to oscillate at that frequency. From memory, there is a transformer and a second circuit coming from the other winding. This extra circuit should also be designed to resonate at that same frequncy, 18khz.

Resonance gives a sort of "pseudo-superconductivity". If both circuits resonate at the driving frequency of the globe, then this "pseudo-superconductivity" runs through the whole apparatus.

Ok, i managed to make a small experiment.

I took a standard 220/30 volts trasformer (windings are isolated) and at input side i connected a resistor in parallel. Transformer specs is
* primary winding 16 ohms resistance, 1.692 H
* secondary below 1 ohm, 27.6 mH

1st try was to connect a 18KOhm resistor and measure output frequency.
2nd try 1Mohm resistor.

Even though are blind resistor values, no deviation in output frequency was measured by my DMM.
...

So, how the f... Don Smith claims he "corrects" the frequency by the application of the transformer's L a parallel R?

Anyone having the chart and willing to do some more detailed measurments have a signal generator?

The only possibility would be if resistor is able to change phase of voltage.
I have no scope so no way to check it.
If that's the case , then it has to be no just one resistor but a clever way to put it maybe like voltage divider with center tap ? I don't know, but if resistor can create a lag on voltage wave then Smith may use that to intermodulation of two waves (in reality this is the same wave just one lags in phase) - that will create a "beat" of other normally slower frequency.
Just an idea

I think the Donald Smith device is interesting and the simplicity would tend to draw you in but like most of the stuff on the web you have to treat it as a non working device.

Reading through some of the materials he makes some interesting points which when tested could provide some clues but is far from complete. The circuits he shows have to many discrepencies in them as well as to little information for the average joe to replicate what he claimed. If it were that easy we would be talking more about the improvement of the device instead of making one work. As a result, everyone would have one with varying degrees of success.

I've seen no evidence anywhere that he actually had a working unit. That of course doesn't mean he didn't but at this point there is no proof he did.

The larger unit he shows, using the storage capacitors could have some interesting effects. Although not shown, the output was pulsed at line frequencies throught the step down transformer by way of a HV semiconductor ( finding one capable of the HV may be challenging and/or expensive ). This would allow a few thousand pulses to bring the cap bank up to peak voltage then discharged throught the step down 1 time. This discharge would be of reasonably high amperage which would give an even higher amperage through the step down. It would, of course, depend primarily on the ability of the NST to bring the caps back to peak between discharges.

Another interesting idea would be to follow the earth grounding between each isolated system through the safety spark gaps which leads to the low voltage output side of the transformer.

I wouldn't get to "stuck" on that resistor or worry about the frequency throught the output. You can always rectify the output and store it in a battery bank and reuse the stored energy through an inverter. Batteries don't care about the frequency of the pulsed DC, they seem to absorb it fairly well.

All the devices I've studdied so far have a few things in common... their not complete in some respect, poorly described, misleading or missing components and all have been claimed to work with no real proof or is simply a fake from someone looking for their 15 minutes of fame.

Look at Kapanadze videos for actual exhibition of working device then return back to Smith device.He seems to use the same concept,but he stores energy temporarily in capacitors.I'm quite sure that most of electrons are in capacitors forever, or they could be if reverted back in clever way.They flow from one terminal to the other.Smith found a magic one-way pump.In his capacitor electrons just flow from one terminal to the other - there is ALWAYS imbalance of electrons - contrary to capacitors in normal circuits.Then he "turn knob" and capacitor is already charged instantly (because they are not polarized ones, self-heeling)

Since it dosnt appear to be easy to calculate the resistor needed, maybe you could try a potentiometer so you have a variable resistor to play with.

Hi Baroutologos,
Looking in the Tables and formulas book Don suggested I bought used.

OK I am looking at the reactance chart for 1 Hz to 1 kHz. Anyway I took the * primary winding 16 ohms resistance, 1.692 H, and drew the line to 120 CPS it says .0012 megohms as close as I could get it.
I did not add or subtract the Resistance you allready have.

Hope this helps.

Thnaks h2ocommuter for the input.
By the way, this is a mains transformer. main is already 60cps.

Nevertheless, i placed a lamp of 40 watts at 220 volts (1200 ohms more or less) and saw no difference. Ok my DMM is not the best at measuring low freqs but something i could have seen.

If you do not bother, can you post the nomograph?
Could you try yourself to see if there is a "resistor/inductor frequency correctance method?

If not, why believeing in Don Smith in the first place?

Details details.

Baroutologos,

Wow I have looked all over the place to get a good nomograph that is digital, without luck.

I guess I can take a pic. and attach it. I give it a try.

I read the book a couple of times, but my verbatim is trashed. I will look it up and Pictures or copy it for effect. try to get it out quickly.

I am so ignorant or the mathskills and the electrical engineering lingo it is embarrasing.

OK the book reguards this nomograph as a resonant tuning chart only.
I am not stupid but you guys could make more sence of what is in it than I could.
heck I only paid like 3 to 6 bucks for it used pluss a couple dollars shipping..

I revisited Dons writing again, with a fresh Doc for clarity. Exactly the same.
Just as you, I felt Don was using this as the frequency adjuster. Oh no, Look again at the writing.
We go to the nomograph to get all the resonant parts for our build! It is right there. We are choosing the values from the start, " the Isolation transformer". Draw the line, Choose the resistor, Now you know the capacitance.... It was like he was telling us point blank and we did not see it.
OK so reading the L of the input side gives us the Farads and the Resistance. period. THIS IS ONLY A RESONANT TIMMING CHART FOR THE ISOLATION TRANSFORMER.. Again it is telling us the Capacitor value and the reistor value from the L of the IT. that is it!

If I am right Don is suggesting that we are not to reduce the freq. comming out of the Isolation Transformer. It seems to me he is associating this energy like a radio freq. in that, the places carrier waves can be used. these carrier waves carry many other frequencies. "I know nothing about that either", So if Don is correct, we are not squeesing back down the freq to achieve the 120 CPS. we are using the nomograph to set the LCR and time constant of the circuit. Kind of like using a carrier wave association to resonance.

Don is gooood hug: humbly speeking. he never said we were changing the freq to somthing else. I guess we are stabilizing it.

Is this making any sence?

I'm gona ad this to my PDF

There is one here http://www.sphere.bc.ca/test/slideru...se-200ee-b.jpg that could be printed out and used to find the values.

Here is the one Don is refering to I believe.. RF Cafe - Frequency - Reactance Nomograph

This one will print on a regular sized printer sheet....

OK, those charts show at x axis the different values of L and C for resonance (0 ohms reactance) at various frequencies, and above that all the possible combinations of C and L and their resulting impedances at various frequencies (again)

Who said, that can work backwards?? i.e. by putting a resistor (thus simulating reactance) in series or parallel to a C or L you can manage to have an desired output frequency?

Baroutologos

I don't see any way that resistor will change frequency, as I said before there may be missing or mis information in anything that is on the net. I wouldn't focus on that resistor in as much as what he might have been trying to accomplish throught the system overall. There are many different ways of lowering the frequency and I don't believe that is one of them. Think of it a a diversion. I believe it was even stated on one of the documents that because of contractual obligations and fear that the information was intentionally incomplete. You have to look at it as a bunch of clues in a large puzzel, you have a few good pieces that fit, some that don't belong and others that are missing. Look at the basics, fit together what makes sense, remove the stuff that doesn't fit, and follow a logical path to find the missing parts.

I do not believe Don is stating we would be changing the freq. I believe he is stating when using the nomograph we are setting the resonance of the system only. That is if we incorporate the capacitors as dictated also by the nomograph.
Furthermore I believe he is stating if we use the other formula voltage desired /capacitance in uF = CPS "the speed and carring value necessary to accomplish the task"

Nuf said.

Ok I have some pictures validating the graph, and validating the readings.
These pictures clearly show why a digital model would be best.
