HIGH QUALITY TPU DVD Video Released from Jack Durban

hi all

@jack,
I am not that much into football, only when we play the european cup or the world cup.
But when I happen to stumble into the guy i will ask for you
if you are interrested in what I do in my spare time:

@all

I dont believe the RPM of the TPU was that high, otherwise a spinning compass would never have kept up with the starting rotating field.

If the earth is a giant radio station, we must be darn close to it, rigth on its surface....

Greetings Rene.

Hi Rene,

I am beginning to think that this device is really a clumsy phase locked loop based design that locks to the Schumann cavity after a little "priming" from an oscillator much like a pull starter on an engine taking it from an idle state to a phase locked one. A tank tuned to 7.8 hz is out of the question in this footprint but a Tesla generator ala 381.970 might be able to couple and lock to it with a little "kick" start.

Hmmmm.

This is exactly the coil arrangement I'm concentrating on, except I'm not using a common at this point so I can drive the two primaries independently. I tried complete all-the-way around windings (as opposed to segmented) and got nothing of consequence.

@ Localjoe

Thanks for the recognition. I built the ring only, 5" diameter and an inch and a half high, with 40 turns of baling wire for the core (not segmented as Tesla said to), primaries of 80 turns each segment of some really rotten aluminum hookup wire I couldn't bear to throw away before I used it for something, 15 turns of scrap 18 gauge copper wire for the secondaries, all wound more or less per the patent, and excited the primary with a single square wave at 3 Vpp (I like three volts for testing these builds as SM couldn't have been using much more than 2 AA batteries to launch the effect, IMHO). The best input frequency changed with the load that was applied, LEDs in this case. At the time I was interested primarily in the magnetic effects to determine whether there was any overlap with SM's device. As it turned out, one of the primary winding pairs was no good, so my testing was limited to half-wave results but accomplished the experimental goal anyway. It would spin a compass smoothly at 2 Hz with only half the device working (see attached photos), and frequencies up to about 30 Hz produced only a quivering of the compass needle confined within its own chosen segment domain. I do plan to revisit the Tesla device someday soon and build a serious replication.

I made the observation in another thread that SM may have used the Tesla patent as the basis for his thinking and saw that the generator/commutator portion could be eliminated with modern devices not available in the 19th century (MOSFETs). An on-board generator powering resonant coils is essentially what the TPU delivers. Our collaborative work here is all about the coils - I believe that the circuits to drive the device will be easy, as suggested by Jack Durban.

On the FTPU, I was wondering why I could not see enough connections to justify 8 coils all in quad. See the animation below. The quads jump from on level to the other. This way you can control both coil levels with one impulse and a back impulse. This will give you guys food for thought while I work out the other connections but it is not easy at all and very time consuming. Please consider the animation as the closest yet to the ftpu function.

Hi buzz-ard,Ã,  I was just about to suggest coils all the way around, they would work great, and infact the OTPU, with the bifilar can make use of the bifilar for such winding.Ã, 

About not getting a result, as in a moving magnetic field I assume,Ã,  I should mention that for the configuration I showed, (where only one phase is available)Ã,   the resistance of coils is usualy very small, and the inductance kind of high, so all these things should be taken into consideration.Ã,   For example, if an output coil to loop back and act as the generator is placed more on Phase 2,Ã,  then it's like a transformer on those coils, and the input to the coils looks resistiveÃ,  (or zero phase depending on the coupling factor).Ã,  Ã,  But if left open, it's inductive, so the phasors will change and it won't rotate.Ã,   I've spent a lot of time pondering the phasors in a looped back system and there's things to consider.Ã,  

On the other hand,Ã,  if a phase with the capacitor is driven at resonance,Ã,  the reactances of those coils and the capacitor will cancel out and will leave a real value, (very low due to the low ohmic resistance of the windings)Ã,  so the current phasor at resonance will then have a phase of zero, and be in phase with the driving signal generator,Ã,  so you see you get zero phase from the resonant winding,Ã,  and zero phase on the other transformer winding, and that' s not good, they need to be 90 degree out of phase.

So what's the solution?Ã,   Well, maybe rotate the receiving unitÃ,  (to create the feedback) somewhat and find a sweet spot.Ã,   I've tried this as well and no luck , nothing lit upÃ,   :)Ã,   But it's still an interesting concept for me and some time later I might revisit these experiments.Ã,   With carefull engineering we should be able to engineer a system that never finds it's balance !!
