Scope shots of clean kicks

I think the follow shot is of a diode in the 6 inch tpu.

Great post Bob! This will be easy to implement in the current ECD.
This same diode could be in the wire bundle of the SM17 at the inner toroids. It is wrapped in tape but we've seen this shape of leads before in our electronic adventures of life.

The (17_32)? in the 17.zip post by Marco is a clear shot. http://www.overunity.com/index.php/topic,712.msg37542.html#msg37542
I am still curious about the SM17 having matching pairs of circuits. Only 2 sets, like the coil is spilt in left and right halves and 2 sets in each half of the circuit.
Only 2 of everything. Shown symmetrically too.

I am interested in what you think.

I can't tell if there's a diode in the SM17 pic - too indistict IMHO. I do believe that diodes are a part of the smaller unit so it makes sense they would also be part of the larger unit.

You are definately on the money on everything being in pairs. Those two yellow cylinders in the center are 1000 volt caps IMO. The two Black capacitors right next to the coil have resistors soldered to the leads. They are right next to the coil because THEY HAVE TO BE. It would make more sense to mount them in the middle otherwise. And why are they near the coil ? - because they form an LCR, one for each coil, and the lead lengths are critical for the resonance. All IMHO of course. Alternatively the caps could be smoothing caps and the resistors are there to limit ringing on the output ?

One of the cut-coil pics showed the top and bottom coils looking like horizontal wound flat ribbon wire. I'm thinking the symmetry is top - bottom, as opposed to left- right. This might explain why this TPU is so thin and tall. Tall to separate the coils. Wasn't there some strange 'wooly' like material between the top and bottom coils ? Perhaps there is also a capacitance effect going on between the top and bottom coils.

I think the small toroids in the middle are high-frequency choke coils.

Thanks. The hidden part tells me axial leaded part. But that isn't difficult.
The tall idea fits with the verticle wing idea for RE emmisions. Think about this: ECD has sharp edges on transmiitter bottom and receptor top. They point along the horizontal plane and are offset by a vertical angle of 45 degrees. With what you noticed the horizontal top and bottom could be the sharp edge receptors. Otto and Roberto have done more with 2 frequencies than with 3. And that ties into the bipolar symmetry of the SM17 and other tpus. The ECD bottom is 6" and the top is 4". That also looks like energy compression which would be like an even higher level of phase intermodulation of the 2 frequencies coming in. 3rd harmonic?

I've been reading anonymously for a while and find this stuff absolutely fascinating.

I've been thinking about what's happening in the operation of these things and will write it out (as simply as I can) and hopefully someone will tell me that I'm wrong/right.

You're sending a moving EM wave through a mobius coil (not a perfect mobius because it doesn't cancel itself completely?) and moving EM wave is creating a standing EM wave in the mobius (double freq. of the wave). Then you're sending another moving wave that is double the frequency of the initial wave that collides with both itself creating a new standing wave and with the previously created standing wave (does this standing wave collapse or combine to create a larger standing wave?). From there you send a third wave that is the first wave frequency plus the second wave frequency through. This creates a third standing wave when it hits itself. Then as things move along the standing wave just gets bigger and bigger if everything is perfectly in sync ultimately creating a standing wave so big that the materials in the device can't contain it. Right? Wrong?

Well, I got my drivers just now!

Fired two of the three drivers up at 1KHz and got the strange oscillation in the waveform seen in the attached video.  The scope is perfectly synced to the 1KHz waveform; this oscillation is way below 1KHz!

The scope probe was attached between the first MOSFET's drain (connected to a driver coil) and ground.  The same oscillation (perfectly in sync) was seen on the second MOSFET's drain.

This driver circuit is extremely stable compared to my previous attempts.  The MOSFETs get warm at a 50% duty cycle, but stay stone cold at a 10% duty cycle.  Rising/falling edges are nice and clean at the MOSFET gates.

More tests to come of course; just wanted to give an update.

EDIT: Overunity.com keeps timing out when I try to upload the video file, so here it is on my slow server:

When I remember right, I have set a limit of about 12 MB per file,
so you should split movies for 2 shorter files then.
Many thanks.

@Eldarion
maybe it is some kind of beat frequency ( Difference frequency of the 1 Khz out of phase signals ?)

Maybe you can better trigger onto this beat frequency ,so one can see it better ?
Does your scope have a storage for the waveforms ?
Then set the timing to very long milliseconds/div and see where the beat waveform occurs.


Please recompress your MPEG movie files to DIVX.com codec or
WMV via Microsoft Windows Media Encoder to get smaller files.

A datarate of 300 to 500 Kbbits/sec for the video should be enough
for a MPEG-4 type encoding.
Many thanks.
