@Wattsup

You are thinking way too conventional...
You try to model away things you know by the book.
This is not the way to go.
We are dealing with other things here and it is not right to approch them using conventional science.
I have no idea if i made this clear but i just want to say, this thing is diffrent.

I got these stepper-motors from a guy in a parking lot today.  It went down like a drug deal for geeks.  :D

Now all I need to do wrestle me some free time to design and build a coil winder around them.

Treid to post this before and it got nuked...

Based one the explanation of packing and stablity, etc. I believe that for an arrangement of 4 coils at 90 degrees to work in a stable way, two other coils have to be added to form an actahedral arrangement.  This is similar to Marinov's arrangement where he used only one DC-fed coil around the other four and produced a "pulsar beam" out the top of the device.  Having a coil at top and bottom may contain the energy and explain why some strange anomolies have been encountered with the 4-coil arrangement and multiples of 4 in a flat plain.

It is my interpretation that all 6 coils in the octahedron arrangement should have the same pole pointing toward a common center.  Depending on the parameters the rotating field may devlop in the 4-coil arrangement which is probably not a good thing, so various parameters would have to be tried to find the correct ones.  It is probable that the optimal dimensions would change with the driving parameters whcih determine where the field occurs.

Of course, the tetrahedral arrangement uses only 4 coils.

Attached is a tested print for a Spherics Type circuit.
...
@all
here is a controller circuit I have designed and tested -- it works perfectly in practice --
...

Looks good - just make sure you put protection diodes across the coils to prevent back-emf from destroying the AND-gates and oscillator.

And / or OR or NOR or NAND or XOR or ... fffftttt.    The LOGIC.  Protect the logic.

The half bridge design that is not only tested and working it's got lots of protection as well... way more robust than anything I have found yet. It should even be better than any of the SSTC (Solid State Tesla Coil) drivers out there.

Half Bridge switch circuit is too big to load here --  and it needs documenting. However here are some tips for getting fast switching:

1. 12 - 24 V gate drive -- faster at the higher voltage.
2. use IRF 820 or other mosfet with low gate capacitance and gate charge -- you want voltage not current.
3. Use ceramic bypass cap on the HV supply -- I use 0.1u 630V cermaic + 0.15 pulse capacitor. THese caps should be right on the mosfets.
4. Fastest driver you will get (at resonable price) is IXYX 414  use the TO 220 package if you want to drive at over 700K repetition rate.

When you do get things switching fast you will need to minimize the gate to drain capacitance and shelid any circuitry within about 50cm -- the EMI is very significant if your switching 100V + in less than 10 ns. If you dont sheild and lay things out right then you glitch your input and get spurious triggering of the switch. You will also need to isolate your logic, driver and output earth lines as much as possible.

You should have TVS's on all power rails -- logic, low side and high side drivers and HV supply. you want schottkey diodes in seris with the mosfets to prevent their body diodes ever getting reverse biased, You also need hyperfast (or SiC) flyback diodes. If you do all of this your mosfets and drivers are likely to last -- if you dont you will blow them regularly.

When testing use 10x or preferable 100x probes on a 100MHz or faster scope. For cleanest results do not touch the output -- just place the scope tip close by.

I have an old book on microfiche - real pain in the arse to read - Titled: "Techniques of Shaping High-Voltage Nanosecond Pulses", by Vorobev,G. A. ; Mesyats,G. A

In this they discuss how you can send a pulse through a spark gap (or multiple gaps) to decrease the fall time (or was it rise time?  maybe it was both? - web source John Pasley says "rise time").  They also used adjascent gaps for UV enhancement of the switching time of the main gap (think he called this a "spark relay").  UV lamps for reptiles may also work, and I'll be trying this along with a brush discharge from a Tesla Disruptive Discharge coil as well, when I have time.  Basically just screwing around trying to get vacuum gap performance without the vacuum.  Hmm - could setup a quenched gap sideways so that each gap UV's the one next to it.

I suppose, when it comes down to it, we need to look at the "entire circuit" when dealing with this sort of "thing".  From this perspective, SS is slow, tubes are faster, and SM was correct.

*if* you wanted really fast pulses you "spark" through water... any you get well down into the picosecond range from memory... but you just dont have to go there, a fast mosfet switch is all you need these days -- easy if your switching under 600V -- it gets a bit trickier up to 1.2 Kv as the parts get more expensive. For the higher voltages - if you really want them - you should just use valves. Valves are cheap, easy and fast for higher voltages -- the current capacity is not a problem at all.

They should have performed this test with Fe. Unfortunately NMR measurement they did with H and C does not work with Fe. :) This is unrelated to SM TPU research.

 ???

Iron 57 has NMR frequency of 3.237778 relative to H1, so its frequency in the Earth's field should be around 6.475KHz.

I know iron 57 is quite rare, but Spherics did not specify which isotope of iron he was referring to, and iron 57 is the only isotope that exhibits NMR if I recall correctly.

Eldarion


@Eldarion

Could you please explain how you arrived at 6.475 KHz?

I came up with a different frequency:

According to Wikipedia -
http://en.wikipedia.org/wiki/Gyromagnetic_ratio

f = (gamma / 2pi) B

Gyromagnetic Ratio (rad T-1 s-1) :    0.8661 x 10 7
Total Magnetic Field Component in my area : 49,850.9 nT

(0.8661e7 / 2pi) ? 49,850.9E-9 = 68.7165 Hz
