Back to Basics

[Grumpy]

Hello all,

Have you TPU builders ever thought about why after 3 years of building nobody has a TPU?
Whats wrong with the theories, coils, setups?
Have you ever thought about to connect your MOSFETs in another way?
Ever thought about why a vibration is needed?
Ever thought about what causes a vibration?
Ever thought about the core - no core confusion?
Ever thought about why the coils are not patented and only the way to control the beast is patented?
Ever thought .......
........
........  have I to continue with my questions?

Have you ever tried to think about what the people here have NOT done and then you tried it?

Of course the answer to all my questions is

NOOOOO

Otto

Vibration is just a secondary effect.

The real reason so many attempts fail is that we can not reliably generate the shockwave, and when we do, we can not reliably make the resulting field move in one direction. 

If the detector is oscillating then the field is not moving in one direction.

Another reason is fear of high voltage.  It only hurts for a short time...LOL!

A magnetic core, causes the field to work on the core and the effect does not occur as there is an easier path for the energy to take.

@Sparks

Good points. His meter is an RMS type.
About the LTPU amperage readings, I had already covered that.

@all

Someone in Europe used my credit card illegally so I have to change it. Meanwhile, I can't use my Paypal to buy this;

http://cgi.ebay.ca/Micronta-True-RMS-Multimeter-Owners-manual-22-175_W0QQitemZ370258992779QQcmdZViewItemQQptZBI_Books_Manuals?hash=item563527de8b&_trksid=p3286.m20.l1116

If anyone can grab it and I will paypal you in about 15-20 days when I get my new card for my paypal account.

This is the only real material I found on the net on SM's Micronta 22-175 RMS Meter. Can't believe there is so little on this meter. Kinda weird. I need this to get the selector button descriptions.

Found the photo below in Google photos but I think it is not the exact model.

Man, that manual on Ebay is all there is to see all the buttons and usages and I cannot move on it. That's even weirder.

But here is some preliminary stuff;

In the following document that I thinkis basically a text version of the manual you can read under the following headings and I will comment below.

UNDERSTANDING PHANTOM READINGS

If you do not connect the meter's probes to a circuit, and set it to DC or
AC VOLTS, the display might show a phantom reading.  This is normal.  The
meter's high input sensitivity produces a wandering effect.  When you
connect the test probes to a circuit, a real measurement appears.

Frame 3063 SM places the volt meter and pushes the power on button. At that point the meter probes where not connected to the FTPU but there was still some readings shown on the meter that changed erratically, unlike what one would expect from unconnected probes. That had bugged me for a long time now and now it is explained.

MEASURING HIGH-VOLTAGE CIRCUITS

When you use the meter to check a high-voltage circuit, do not try to
position both probes at once.  Instead, clamp one probe to the neutral or
ground lead of the circuit (usually a bare, green, or white lead in AC
wiring circuits) using insulated Slip-On Alligator Clips (Cat. No.
270-354).  Then, probe for voltages with the other probe.  This helps
prevent you from accidentally touching a hot wire, because you need
concentrate on only one test probe.

That's exactly what he did. He connected the meter negative first to the FTPU wire on the lower ring, then the positive on the top ring.

Another thing that's weird is the above manual is about the only concrete thing that I know SM would have read. If anyone in the USA can pick it up, please PM me and I will give you my office fax number to fax it, or, if you can scan it and pdf it, or zip it, with thanks. Also let me know the item and fax costs and where I can paypal you back ASAP.

@All TPU-dogs:

I've been conducting basic TPU experiment with the coil in the picture:

6wrap iron wire core, terminating as secondary output. 24 wraps single core copper wound around that is the primary (bifilar option not used in this experiment).

I set up a FWBR of 1n4148 on the output charging a 470uF cap. I recorded the charge curve on my DSO and so I could calculate average harvested power.

I expected only minimal trafo efficiency, I tuned for optimum VDC out of the FWBR, at around 7.6MHz sin input I was suprised:

Input signal accross primary was 560mV p2p, output across secondary was 1.2V p2p. A 1:2 trafo ratio from a 24:6 (4:1) turns ratio?

My suprise did not stop there: the iron wire output was able to charge the cap faster than the signal generator (same settings) hooked straight up to the FWBR (no coils in circuit). There seemed approx 10% more available power with the coil trafo in place?

How could coil coupling exceed squirting the signal straight into the FWBR? I have never seen a case like this in previous experiments with highF trafos, usually squirting sig-gen straight into FWBR always outperforms the trafo being tested?

[Yucca]

I'm presuming diode losses are less significant at higher p2p, but still I am suprised at greater harvesting ability with the coil being used as opposed to sig-gen straight into FWBR.

My next task is to try and match the natural system resonance of both pri and sec.

I have found that my tektronix FG504 sig-gen with my DSO gives me the ability to do spectrum analysis: I set the gen to linear sweep from 0...40 MHz every 100ms. My scope is set to 10ms/div and triggered by the gen sweep start signal. Then when I scope the FWBR output (no cap in place) I get a nice frequency response graph displayed on my scope with 4MHz per horiz division. I will now change pri wire length and turns until I get both response peaks overlapping. These experiments will start in the AM europe time.

@Yucca,   nice !   Is there a power increase or just voltage increase?  I get those easily, we want that power to increase. The voltages also have to do with the loading.  If your signal gen. is a 50 ohm source impedance, and you hook it up to a low impedance, you have a voltage divider that lowers the voltage at the terminals.  Resonance will increase the voltage for sure, which is what you are seeing most likely. Can you draw a diagram or schematic.

@otto,   I think people have failed because they don't do what the real SM is saying to do.  We all have a tendancy to imagine more than we need to.  We like to imagine exotic phenomena, vortexes, etc., but all SM said in the videos is to tune into a magnetic frequency with the loop antenna he has (TPU)   It's not a simple one but that's the basic description of the TPU based on definitions alone.

1) this requires first to identify a frequency
2) to tune the device to that frequency

we don't identify anything but rather play with Mosfets and power supplies and focus on switching etc..,  I am convinced that this is not where it's at.  It might use switching but only for power regulation as an output stage.  So as long as we dream up exotic ideas and don't do the basics we'll never have OU, just fancy switching and beautiful PC boards.   This is an OU forum, so lets go after OU, let's identify a source and work on harnessing the energy.
