Grumpy...good thoughts

What I was getting at is this: There are no other apparent connections to the chokes. The wires from the first choke go into the large 17" core and back out again and then connect to the second choke.

I am implying that this is some sort of parasitic resonator/absorber that has no other electrical connections to it. It is then passive being electrically driven by induction or it is used to drive the A vector of the chokes.

No visible electrical connection to an oscillator circuit. (unless the connection is made somewhere as a tap inside the black cork material.)

For a while I thought the connections were made through drilled holes in the black box, but the metal mounting brackets forced me to abandon that idea.

Take another look.

Can't even be sure that those wires connect to the chokes - could be smoke and mirrors - lots of other wires floating aroung.  Could have just ran them through the chokes.  The close-up of the chokes (can see the divider) in one view shows more than 4 wires.  Also the magnet wire of the choke doesn't show any indication of a termination except, maybe, in the close-up.

Notice the fuse(s) on the side?

SM has used the terms oscillation and frequency several times - I know this is inconclusive.

Hey you guys.

The two inductors in the center are used to first start up the unit. Look at large22.jpg where SM is using a magnet in his right hand and lowers it close to an inductor. He is producing his initial starting pulses via the inductor, probably collecting the produced starter current in the cap or caps (could be start cap/ run cap). He then moves the magnet to the other inductor for a while (see large19.jpg and large 20.jpg) and bingo, the unit is pumping and raring to go. Yes the inductor seems to be off-the-shelf because they have two prefab terminal on them. I was thinking maybe for a doorbell type device.

Thomas put up a very good must read pdf on his post number 1357.

Maybe you could take the picture of the cutaway and add some arrows to show what you are talking about because I really can't see it. I tried getting better grabs but the cutting of the TPU was so badly videoed and there is really no part of the video that has any better resolution. This is a shame.

here, I'm putting up all the other grabs from the cutaway in case something may be seen more clearly by some.

On thing that really struck me is how the cut portion held together so well. You would expect that after a heavy round with a jigsaw, the cutaway edges would be badly cut, with tape torn off the edges, or some other type of damage, but no, the cut part held together. Weird.

Is it possible that the inductors are current sensing type. By passing the main current through the sensor centers, the circuit (below) knows the current level and adjusts the pulses accordingly. This could be how he controls the maximum current production of the unit, otherwise as he said, the TPU could burn up. This could also be how he starts the unit. Since the center wires have no current, the starting magnet induces a small current that the inductor senses and pulses the TPU accordingly. As the TPU starts producing current it then passes through the sensors and the circuit to maintian a maximum.

Have a look at SMTPU2.jpg, very simple design happening here.  4 winds going on north, south, east and west with magents between the windings, looks like one other coil but can't see it clearly.
