Step charge being born and mastering TAU (video)
« on July 14th, 2018, 06:02 AM »
1vPTP signal out of my amp and monitored at the secondary via my PC based scope. Note, this is just an AM modulated signal with the carrier at 4khz and TAU at .333hz. Step charge is born here and once this signal is rectified via a diode two things will happen, the frequency will double and the TAU will half, chopping off 50% of the trailing edge of each modulation. This leaves the signal above the DC offset and removes the step down effect, so you are left with a step up effect only which I have already achieved (video to follow later). Meanwhile to fully understand what is going on here, i've made it as easy as possible.
We move forward.

New cell under construction. This cell is different from all my previous designs. It is parallel capacitance and different diameter SS tubing. There are going to be different dielectric properties to the tubing, the three tubes can be driven individually or 1, 2 or 3 configuration along with a fourth switch which can bring in a gamma match. It is fed with 50 ohm coax into its SO239 socket. Crude but simple design can vibrate acoustically to prevent bubble lock. My transformers are modified, my audio amp is working brilliantly and my new project box is in the post along with higher spec diodes along with matching resistors. I'm going to replicate Dr Andrija Puharich's research word for word and i've got a good idea with the drive frequencies so far. Last chance saloon for me so wish me luck.

From what i've learned so far from Puharich:- There appears to be a pulse driven series of harmonics apparent in an AM modulation. The length of the series of pulses is determined by the length of time of the audio signal (TAU), the rising edge of the modulation of TAU causes an apparent step charge effect of the harmonic pulses and the trailing edge of TAU modulation causes a step down effect of the same pulses. If you set the carrier at 1990 or 3980hz which Puharich states is the latter stages of high efficiency electrolysis, and you modulate it with 0.333hz, the harmonics are very apparent. Experimenting with a square wave being modulated brings in the harmonics much better than a sine wave though and I think Stan knew this and TBH I think Stan is cutting out certain stages of Puharich's work or taking short cuts. Lots more work to do yet and more experimentation taking place to get to grips with Puharich's patent.

New control box half built. Audio amp is in, step up transformer is in choke is in, amp and volt meter in, SO239 output fitted. Waiting for high speed diode, resistors and some HV switches to arrive before its all soldered together. Also need to construct the wiper arm for the variable inductor (negative choke).

Looking good Nav!

I've been going through your posts of the past few weeks. Some very useful insights there. An interesting track that merits further research.
I hope to pitch in when I can. In the meantime, best of luck with your efforts!

A little something to ponder...

The best of both worlds...

A clipped sine wave.  Look at the harmonics in that baby.

That looks familiar. It looks exactly like what I get when I try to externally drive an LC circuit off-resonance. Are you sure you've got your inductances and capacitances exactly right? When you do, it'll ring longer, without the "rise-dip-rise-dip" peaks shown in the image.

Matt, I don't know the ability of your signal generator but have you tried modulating a sine wave with it's first harmonic without clipping the sine wave? The harmonics seem to multiply in intensity especially if you create a dual modulation.
For example, if you start off with 1990hz carrier and modulate that frequency with 0.333hz, you get a lovely signal building but the harmonic distortion is a very low percentage. However, if you superimpose a secondary carrier and modulation over the top of the first with a frequency 3980hz carrier modulated at 0.333hz things change. Obviously you have kept the entire length of the modulation to three seconds but the harmonics now begin to dominate proceedings and distortion levels go up significantly. Producing a kind of pulsating modulation all way across the scope.

It would be interesting to know the dynamics of Stan's alternator/variac/gated design Matt. There appears to be no filtering in any of the schematics and through testing by myself and others on here, we know the outcome of unfiltered switching through bipolar transistors, fets and diodes. Harmonic distortion seems to be all over the place and imagine the H-bridge designs and what is taking place there.
Matt, you clipped 180 degrees of the signal, how did you clip it? Was it through signal generation or was it clipped in circuit?

It's ironic Matt, all those years ago when You, Ronnie, myself and others were trying to filter out the harmonic spikes on the leading edge of a 50% duty cycle pulse in a 555 timer and the same problem we had in the trannies and fets.
Andrija Puharich is actually telling us to harvest them in his patent PMSL.

We don't know at this stage what Matt is driving with this signal. Hard to say until he comes back with more information about where this signal is manifesting. If he's driving an LC circuit out of resonance then you would be indeed correct and a simple sweep of the sig gen would put him in the ball park, find the resonance and lower distortion. See what Matt says about the circuit first though.

A few more things today. The volt and amp meter is set up with the audio amp and working 100%. High speed diode is on the cooling block with a little cpu paste and the post which will hold the wiper arm is in place. Waiting for the resistors for impedance matching the audio input to the output of the chokes.
Please note, those Kinter amps can output no where near the stated output of 500w. I've tested it and you will be pushing it to get more than 60w total, 30w per channel is about the limit but that's not what it's there for, it's there to amplify the sig gen output and it is quite responsive to any signal between 20hz-20khz. It also deals with the TAU frequency reasonably well give or take.
The name of the game is to investigate what Andrija Puharich is saying in his patent concerning modulated audio signals.

By the way Matt, the circuit will be switchable between the high speed diode and no diode. I've ordered an high voltage three way switch. We'll see the signal either way.

This is a current signal driven into a transformer, seemingly unimportant until you see what comes out as voltage.



That white trace is the dv/dt, otherwise known as induction.

The signal is produced digitally with an arbitrary waveform generator.  If you know anything about Digital to Analog Converters, you may wonder why an IDAC is always 5-10 times faster than a VDAC.  Some may say, "It's the nature of electricity."  They would be correct but their answer incomplete.  Magnetism (current) is always faster than Dielectricity (voltage) and there is a good reason why--review Ed Leedskalnin's Perpetual Motion Holder.

If you want something special to happen on the secondary side of a transformer that you do not want reflected back to the primary, your input signal is very important.  You want the energy (all of it) to stay where you put it.  The clipped sine wave is an important key.  It does something during induction I have yet to see any other waveform do.

I've looked back through hundreds of OU circuits and the common theme in many of them is rectification.  Could be clue...

for audio amps there are 2 different power values: music power and sine power.

so audio amplifiers sometimes have high music power values but poor sine wave power values.

to get a true high power amp you have to ask for "true sine power" value.

There's ol' Gunther.  Thought you had fallen off the map.

And another aspect Nav...  You will find driving current produces much better waveforms than driving voltage.  Slew rate is everything.

I've been toying with this circuit.  It needs improvement, but I suspect it can be tweaked enough to be quite useful.

The Op-Amp needs to have a much higher slew rate for starters.  An LM324 won't do.  I can find low voltage Op-Amps that have a good slew rate like the TLV2774, but it cannot handle enough voltage to really bias a MOSFET and certainly not enough current to bias a bipolar transistor.  Then we have the gate charge of the MOSFET while pushing back-n-forth through the Miller Region, so we need some burst of current to do this effectively.  An IRF630 has a reasonably low gate capacitance, so if our frequency isn't way up there near the top of the audio spectrum, we should be able to drive it quite well.

This circuit takes a line level voltage and turns it roughly into an equivalent current (a transconductance amplifier)--one volt, to one amp.  Then we pick how many volts we need based on the turns ratio of our transformer.  So once we have the voltage picked, we need the proper drop resistor to provide the voltage needed for feedback to the Op-Amp.  It's all kind of pain in the butt, but doable--there's not a hundred parts here to adjust, just a handful.

I'll do some more tinkering with it later this week and let you know if it will do the job.

I'm just occupied with impedance matching the output of the amp to the primary at the moment Matt but I'll take a look. I'm toying with parallel resistance across the input terminals of the primary, my amp is happy anywhere between 4-16 ohms with optimum at 8 ohms. It's all dependent on the feedback the primary is receiving from the secondary on this AM signal, i'm hoping I can put a resister in the value of 4-10 ohms across if the impedance of my step up transformer moves into the kiloohms or just leave it be if it isn't. The dc resistance of the primary is dead on 10 ohms but the reactance of the step up transformer along with the chokes is an unknown at the moment because of the modulated carrier wave, I just don't know how it will perform.
