...the key is the POWER SUPPLY....it is an active power supply...I tore it apart and immediately saw the Tesla/Meyers connection....(THERE IS A 200V CAPACITOR WHO'S NEGATIVE GOES TO AN INSULATED PLATE "OPEN CIRCUIT").....It is giving out pulsed DC.....but special kind, If I look at it on my scope in the 20-50v range, all I see is a 30v DC line right....but If I zoom in to 2v setting...it is step charging and discharging...meaning the "straight line" at this power looks like saw teeth of a hack saw.... Also the output is through a torroidal bifilar coil...

This is a quote from a very early post in this thread.  It indicates a couple of things to me.  The part about the 200V capacitor having its negative lead going only to an "open circuit" is clearly an incorrect observation.  I will bet money that the minus side of that cap is connected to the input bridge rectifier minus terminal and also to the main switching transistor's source or emitter, among other things.  You must be looking at only one side of a two-sided board.

The observation that the power supply gives out "a special kind of pulsed DC" is humorously naive as well.  All switching power supplies exhibit "ripple".  It sounds like this is a cheapie and has a fair amount of ripple.  That is not uncommon and certainly is nothing special or "Tesla/Meyers" related.

To answer your repeated question regarding "how could it ever put out more than 27V", it is clear that there are two other common-knowledge facts that are completely unknown and mysterious to the author/experimenter:

1.  The way voltage regulation takes place in a switching power supply is by way of PWM or pulse width modulation.  The turns ratio of the transformer only establishes a range; the actual output voltage is detertmined by a feedback loop which is easily upset by RF radiation and which controls a chip that performs the PWM function, which in turn sets the output voltage.

2.  An earlier post proclaimed that the output voltage was "regulated by a 30V capacitor".  That is simply incorrect, as the capacitor has nothing to do with regulating the output voltage.  Furthermore, a capacitor rated at 30V will generall survive surges up to 40-45V for short periods, so it is entirely plausible that a higher voltage than 27V could be present on that capacitor.

Since those posts, there have been numerous arguments that the power supply has been measured and only puts out 27V.  The point is, however, that the supply was not measured during the video we watched where the motor sped up when "beaded" as opposed to hooked up straight.

I don't think Stefan is saying that your experiment doesn't work, and I know that I'm not saying that at this point, either.  What I am saying is that all of your arguments as to why the theory of supply voltage deregulation is impossible are obviously faulty.  I am also saying that your understanding of basic conventional electronics and switching power supplies is lacking.  I'd still suggest re-doing the first video experiment with a battery in place of the power supply.  If the motor still speeds up when going through the bead, then you'll have something interesting.

... you can spend easily 2000$ for a GOOD
regulated labratory power supply.
And even that supply would have some limitations
on powering rf circuits .... (...)(...)

.....Haha....all I can do is laugh at people like you. I find it absolutely hilarious that you insult my intelligence and call me naive, while at the same time you you make "ass"umptions on a circuit you have never seen. Trust me Linda, just because I do not use terminology that fits with your snobbish pedigree, does not mean I am naive in any way.
I believe Tesla, I believe he knew exactly what he was doing....as well as he knew exactly how to say it. So please pardon me when I say "regulated power supply" What I mean by that is this.....there are 2 circuits....first circuit rectifies the 120VAC, and feeds it to a 200v capacitor, the capacitor is then pulsed to the step down transformer, via an N-Channel Mosfet, triggered by a sensing loop on the step down transformer...thats the 1st circuit....2nd circuit is as follows.......step down transformer's secondary output (complete isolation) is then rectified again...then fed to a 35V capacitor.......that capacitor is then pulsed via a small transistor, triggered by an opto-isolator running off the 1st circuit via a logic timer...like a 555....this is then pulsed out through a bifilar choke coil....and thats that!!

So....I find your attitude and your wording, VERY telling as to what kind of agenda you have Linda!....I understand if you put a higher voltage into a transformer it's output is higher!.....Here's the thing Linda...I took measurements on true wall RMS....it wads 119VAC @ .54amps....True RMS at motor was 27VDC @ 2 amps....The only thing that changes is frequency...I verified it.....AND I DON"T CARE IF YOU BELIEVE!!...when i get another ADP model power supply, I'll make a video just for you k??...However this test is small stuff....I am moving up to 110Kv....
I honestly don't care Linda...I just take offense when people call me naive...I may not be classically brainwashed...oops I mean trained.....In electrical engineering...However, I know my physics very well....(and the Tesla approach is purely physical)

Ya, that's all I have to say bout that!!.....You guys are on your own. I am moving onto a much larger scale project......and I am tired of trying to separate the "Pros" from the "Hoes"....think about it....if an agency wanted to keep something down....or keep it out of public knowledge...how would they do it???
Answer....providing a place for people to talk, then talking all kinds of trash....Now there I am not totally paranoid...I know that people have a hard time changing learned thought...But like I said.....I am tired of trying to separate the "Pros" from the "Hoes"

One other thing Linda....How would RF upset a PLL circuits output voltage....Isn't maximum V determined by resistors??? Resistors that feed the Mosfet???....Neither RF, nor any other type of noise (radiation) can effect the R values...So V will remain constant...the only thing "noise" can alter is frequency!!!
You give yourself too much credit.....or I not enough...You decide which

Well, well, well.  So I am a "Hoe" with a secret agenda then?  Your description of the power supply is getting closer to being factual (what about the minus side of the 200V cap?  I'm right, am I not?).  That's good, you must be learning somethng.  You again continue to show that you do not understand how your power supply works when you refer to it as a PLL circuit and talk about the voltage being set by resistors that feed the MOSFET.  I know the circuitry of switching power supplies, including the one you refer to.  It contains no phase locked loops (PLL) and no 555 timers.  It has a PWM controller chip.

The MOSFET is driven by a PWM chip and not directly by a resistive divider.  The feedback signal does go through a resistive divider and an opto-isolator before it gets into the PWM chip's input.  RF does not effect the values of the resistors, of course.  It can very easily effect the overall amplitude of either the correction signal or the reference signal at the PWM chip, thus changing the PWM duty cycle and finally the output voltage.  Most simple PWM chips use a constant frequency and vary only the duty cycle (as I said) to keep the output voltage in regulation over a varying load current.  Strong RF in the vicinity can easily disrupt the feedback circuit and error amplifier signals.  It is well known.

Your power supply is very common, totally normal, extremely simple and has nothing to do with Tesla.  It still seems like you would rather become emotional and insulting than just look at what people are saying which, by the way, is 100% true and very well known in the case of power supplies going out of regulation when subjected to strong conducted RFI.  The more you rant and rave about how that is just completely impossible with your special power supply, the more obvious it becomes to anyone experienced in these matters that you are indeed naive.  Sorry, but it's true, whether you like it or not.

Anyway, you again miss the entire point.  Nobody is attacking you or your project.  Some of us are curious whether the effect of the motor speeding up when powered through your bead is a genuine anomaly or if it can be explained by other, well-known RF bench effects.  Your stubborn and just plain incorrect arguments and now your resorting to calling people whores with secret hidden agendas shows everyone that you are widely missing the point.  The point being:  TRY USING SCIENTIFIC METHOD, SIR! 

Eliminate these pesky theories people like me pop up with not by getting all emotional and rudely insulting them and babbling on and on most ignorantly about how you think your power supply is magically immune from all possible RF interference, but shut us down by using good old fashioned simple scientific proof!   It should be very easy.  Why are you so resistant to a simple test?

Stefan, myself and others have asked all along that you simply show the supply voltage on a scope or even on a meter while you do the motor speed-up bead experiment or just use a battery instead of the power supply to quickly eliminate what you consider to be our silly theories about possible power supply deregulation.  NOW WHAT IS SO DARN TOUGH ABOUT THAT?
