Donald Smith Devices too good to be true

[p75213]

What I wanted to illustrate to you with 12V NST is this: if you take the HV output, and connect one side of an HV diode to (EARTH) ground and the other to the HV output of the nst, while you have a spark plug or Gas Discharge Tube (GDT) in parallel with the diode, you have little spark. Only when you take a battery terminal(doesn't matter which) and air ground it to a counterpoise (un Earth grounded mass of metal), you create strong sparks on the spark plug or GDT.

Most importantly, take your reading off your gaussmeter. I was getting 30 microtesla (300 milligauss), and what Don said, "One Milligauss is the magnetic flux equivalent of approximately 100 Volts of active energy" which means I have 30KV of active energy. Where you find this energy is not where you expect using your gaussmeter.

Interesting. I'd have to ask why?

Hi ilandtan,
first, my nst's arrived. i ordered two same freight cost for one or two. both appear faulty! will not run properly. what i do have is a couple of HR208 flyback transfomers, no diode built in. it has been raininng heavily here so no work on the house. i have put my figueras device on hold while i work through the theory more slowly. i still cannot get past some sort of radiant effect is needed for the massive output. time will guide me.

i am back on the Don at the moment trying to rationalise the electret theories. i have ordered some machining for a reusable mould for the canaubra wax as a short term fix. all my polymer tests have ultimately returned either positive or negative homocharges, which i think has to be material related. however it is possible that i should build a corona discharge cabinet as this might be a better solution for the polymers, or so the related information suggests. homocharges look to be more difficult to harvest, requiring contra voltage to charge for performance. ok in microphones where it is low level voltage.

i will look for a plasma globe and start this test. i had wondered about the coil and its Rx/Tx. will keep in touch when a globe surfaces.

Germanian diodes

Hi ilandtan,
I have read the article you referred to. I did not see any diodes in the Utube video link. My understanding is that germanian diodes are low voltages and susceptible to junction breakdown with any overloading. One of the reasons they went out of fashion?

Have a globe on order.

Hi ilandtan,
I got chinese instructions and screen prompts, my night classes are not easy! I am getting approx 13.2uT ==> 132mG. Frequency is coming in around 575.6 k Hz with a 1sec gate. i suppose if the input increased the output in uT would increase to a saturation point? I need a different circuit to modulate the input to test that theory. Interestingly, it took a couple of minutes for the flux to develop about the coil when it remained quite steady. Good lesson!

Mine came from Amazon, instruction and display in English. So part of my realization of DS, was he learned to capture the radio frequencies off these devices (see my post with plasma tube). Look at his description how to build the plasma ball device. If the frequency is around 30kHz, and he is telling you:

Get about 30 feet (10m) of Jumbo-Speaker Cable

what do you think he is doing? Creating an RF antenna. The harmonic he is using is an obvious choice. Do the math and tell me if you agree?
BTW - I can tell you that my plasma ball gets about 370mG of magnetic induction.

Hi Dwane,

I don't know if you have had a chance to use your meters on your Tesla coil RX/TX, but you should be able to see output in uT and then calculate the milligauss. You should be able to capture the radio frequency. Mine was around 500kHz.

Hi ilandtan,
still thinking of you! been busy with building, figueras and patiently waiting for bits and pieces. the two meters have now arrived , flux and frequency counter, still waiting for the neon transformer. have ordered one with adjustable control. seem to remember Don using one of these. earliest delivery date is 22 may! and between june 13. maybe it is slow because trump has been trumpeting?

patience is a virtue best learned sitting down

Has anyone tried to build a simple "small" Tesla that is calculated for the output voltage that you are looking for? It would actually be a small thing because it doesn't need to put out millions of volts. Pass the output lead through say 3 parallel MVO diodes and you have your pulsed dc. Tune the Tesla to the frequency you want and most likely you will not burn that one out with a direct short either.
The junk made today is designed to fail so you will buy more. Not last. Run the Tesla in a vat of oil and you can make it "invincible", not really but a good arc snubber.

What do you mean small tesla coil? What are you trying to do?

[thaelin]

NST or?

I think the midget nst should be just fine, to see the effect I want to illustrate. Don Smith said ignition coils bring lots of power. I have to look for that quote. But I wouldn't spend a whole lot, you just need to have your measurement gear and the ability to create flux, by pulsing Earth ground.

Well, I went to order and they are out of stock! Have ordered a grid voltage unit from China. more patience required. Have received the flux meter, just waiting on the frequency counter. Will keep you apprised of the postal system!!

Hi ilandtan,
thanks for the info. I have found this nst that is imported from USA Midget.

What worries me about the nst is their sensitivity to circuit breaking. they seem to breakdown very easily. They are not designed for the work we are doing imho. i have bought two over the past year and both have broken down. for me at $90 a time they don't look like a good investment. I also have a yihau 3010d which has caused me many problems. it seems that the manufacturing process if too cheap these days. not built to last. I am wondering if I should spend the time and try and build a hv supply using say an auto ignition coil. the only thing is will they run at 30khz+.

let me know what you think of the midget nst specs.

Don't have a NST. i had been using it for charging my capacitor tests. for some reason it stop working. i would be back to using a tv flyback transformer. NST's are difficult to get at the moment what with all the led displays.have everything else.

I use 12V NST, circuits, so I have isolation from the grid, and also ask why Don's device seem to be run from batteries. His "Commercial Device" running a 120V Luminous Tube Transformer, is being driven by an inverter via a 12V battery. Why didn't he just plug it into AC?

I think there is something to it. You can see the magnetic energy Don was talking about.

This is the NST I use, and got it from here: https://www.amazing1.com/neon-transformers-12v.html

I'm sure there are equivalents.

[Dwane]

You probably already have:

12V NST
Spark Gap or GDT 220V or above
HV Diode that can rectify directly from NST HV
