Hi All
             Probably by the time you commented on this device you didn't know about the A videos of Don L smith on youtube, but I do recall in one of this he said "people had a problem making this and I have to tell them how, they are making them in Russia now" this quote is not verbatim but you can watch the video and confirm the idea behind it, thing is, he was an engineer and way beyond even tesla at least technology wise, he assumes everyone trying to build this devices knows the simple basics of engineering for he is used to it!... In reality we are a bunch of dummies overseing this facts, I do have some engineering experience, not to say it is our fault , he said he is not saying everything but you can see in his eyes the benevolent profesor that he is, just trying to make us think on our own,I believe he was just trying to tell us that: study the basics and you will tune up this machine just right for it needs to be in resonance.Variable speed controllers and so forth sound just right from that point of view, -easy?- not even for the intuitive mind!, otherwise we would've have this machine already... One thing I do know due to my experimenting, even the wrong type of capacitors will set you up for failure, some retain this hight frequency electricity some don't, I know because I pulsed several types of capacitors, and batteries, sounds complicated? basically I just shorted out a capacitor and batteries charging circuit!-manually-but if I didn't do it just right, nothing would show up on the multimeter! John Bedini has a video were he shows 2 types of electricity the yellow one and the most intriguing one , also mentioned by tesla and described as a "gas",etc, that can't be easily measured: the blue spark energy...this last one killed almost instantly by the yellow one, see? see the predicament? we have to be faster than this forms of energy! Bedini figured out how to separate both of them! I've seen both sparks while at it,The right capacitor and battery able to retain this tricky blue spark will light up an LED but a multimeter will give you no reliable readings and viceversa, our instruments  are not suit up for the task but you can observe the physical effects somehow, it lights up brightly for and instant then again it is just from one manual pulse! I thing Smith-obvioulsy- found the way to make this pulse continuous. I did used a radio "cheap"(you can't find sh... over there this days), excuse me radio shack 12v 7amh battery to reach 150,200 volts in a recharcheable disposable camera cap, I know many would say," Ho it is just a memory effect of this type of cap" But I don't think so, ok ok go to the forum related to it, but see? you must thing "multidemensionally" everything is related...Then again it begs the question, where is he now? what hapened to all of this great machines ? Where are the fabulous applications of this technology?, Do you know what I would do if all of this were practical and the world wouldn't believe me?, which I think is the case.... I would make my money and dissapear in brasil living in my own supersecret facility , why would I save a world that don't want to be saved?
Yes just like Tesla and Marconi it's been said did that very same thing... But don't loose faith please, do it for all of the innocents whom don't know better...

Cheers

Not the same device, but another of his (Don). In the picture "Useful Circuits From Nikolai Tesla", the one in the lower right corner. Look Carefully, you see that top and bottom windings are NOT turned the same way. Not sure if this is a typo and/or this is also something that is present in Don's devices.

Im trying to learn how to use "LTSpice IV" To learn how to tune these devices.

This D.Smith link explain, that he is fully unseriosly to
bring such UNWORKABLE and NONSENSE
as "inventor an SCHEMATA SELLER to the pubilc.

THIS IS fully "destructive" for Beginners, to hope..
and lost money.

This Circuit (Link) contains at minimum 3 BIG "bugs" so
-because any of each. NOTHING can work from this
schemata .  Ask your school teacher, your radio-repair-men
or (better an radio amateur) anyone , with "basic" on physic.
find in overview fis bugs. (no needs to learn the text or to
compare with  attatched Tesla Patents,(that needs an "higher" understanding in electronics...


So your "sourounding" or users here can explain (each) better than me,because litte bit difficult, my natif language is german, and my englisch ist to low graded , to do the work....


Gustav Pese

because this is an physical - electrival nonsense.


To learn and become knowledges over electrontic .
it dont need to find out fierst the errors  and problems
from and author and inventer, that an lot of people
give attention at first.
so mutch errors begnning wron polarit of diode,
wrong application of an voltage divider (that divide also the ampereage
 Exa,ple here 1000 to 1.. so the enerie (watts) are also divides 1000:1.  So that never an 20KW inverter (12V) can connected this way on an ohnic-resitive divider.
any one have idea, vor the rectifier brige (must bei 10KW and usabel for RF (Highfrequencies. here ist uses 100Khz / 500 Khz about !! Anyone have think about it ?

So you have 3 different points, includes 2 "faults"  it have more, sothis divive is an robbery for yoir time, so it dont need
to buy any experimental sets ...
