The Master Of Magnetics "Steven Mark"

If anyone is interested in a nice, inexpensive usb oscope/freq.generator for the pc check this out.
It comes in a kit, but he'll assemble it for you at additional cost.

I'm buying one today if he answers my email favorably, about where to connect the probes.



Note to stefan: don't turn my posting into your ads please. Many people can't even follow those links as ad houses are blocked by their computers. You can do it all you wan't to your own ebay ads, but I was trying to show someone something and ask for advice, and I don't appreciate that. That's just going a bit to far hijacking other people's posts for no other reason than to make money, and make them look like ad hound jerks.

hi group,
I have uploaded the video to megaupload as Tao sugested.

Look at the top right-hand side of the web page, you should see a button and counts down from 60 seconds and then says "Click here to download".

It's there, just hard to see if you don't know where to look.

ALSO, make sure you have java script enabled...............

GOT IT! thanks...

That'll teach me to pay a litte more attention.

Ha! At any rate take a look at that ebay item I posted about, tell me if it looks ok to you. I assume it's using a MAX chip. But he doesn't specify. I figured I'd put it in an altoids case.

I guess I'll find out for myself, but does the video confirm in any way our suspicions about how it's wound? Your 3d diagrams are nice by the way, that's exactly how I envisioned them.

Well,
I just watched it again in single step with media player classic again
and at 38:30 min Steven lifts the open core TPU device and you can
easily see, that it just has 2 big about 10 windings coils on the
lower core parts only...

Does somebody recognize what kind of core ring this it at all ?

Is this some kind of commercial available ferrite core ?
That would really help, if we could locate such a core...
Then the first experiments would be much easier...
Maybe it is a core from an old TV tube magnetic deflection unit which
normally sits on the neck of a TV tube ?

I guess as this is the easiest device, he might just have
only got 2 or 4 iron wire LC circuits in the right
setup and phase angle setup and with the magnets he
is just putting a remanz level magnetisation onto the iron wire
coils, so they don?t pulse with AC but with chopped DC..
The capacitors are a little hard to see in this segment...

This open device looks so simple build it must be probably
only a few LC circuits, maybe a small circuit driver in one
of the footer stands of it for generating a few pulses into the
coils , if at all ?
In some segments he says, it is just a clever combination
of coils and phase angle setup, so he might evenm
have no circuit over there in it, but just uses the magnets
to induce small inductions which will go into sustained
oscillation and the oscillation will rise and rise,
until his 91 Volts chopped Dc or so is reached...

2. When they disassembled through sawing the bigger unit,
it looks like the core is really made out of wood or kork and
just a coil is wound toroidal around it. Not wound around the
center axis, but wound toroidal like a toroidal transformer.
This can also be seen, as he saws the thing through, he only has to cut
ONE or TWO wires with his "cutter knife-clamp".
If it would be wound around the center axis of this wood core
(like cylindrical onto the surface) , he would have to cut many more wires
and could not saw through it with a wood sawing unit !

So this verifies, that the coils are wound toroidal around this wood core.

Regards, Stefan.
