Bloch wall disconnect and reconnect. The final design!

Thanks for the link and pics. I'll have a lot to study in the next few days.
I already knew about Farnsworth's multipactor but your version looks intriguing.

Cheers

A micromultipactor. A version of EVGray, Dollard's and Smith horizontal tube coil. Just a little different but the same.

LOL, looks like the center of the LTPU. Does this work? Please enlighten us on the results.

I built this for another build test from something Wattsup mentioned with a different set of specs for coils that Bruce_tpu made. And yes it is the center toroids. It is the TPU engine. All the units have this. The bigger rings of the the devices are for effective aperture, the power amplification stage. Just wires, that is why SM cuts them and on the opentpu he handles it gingerly. It will shock. He never lets anybody touch the smaller open unit. The section of windings shown on the open tpu is the sectional wind on the center toroids. The position is just outside instead of inside.
The new param is the primary red 30awg 1/4 wavelgth of the secondary green 26awg wavelength.
The secondary controls the run frequency. I have found that regardless of the input frequency the natural frequency of the secondary rules. I have even added pf tuning caps and the output frequency is tunable within the bandwith of the natural frequency.
So that told me that Don is correct in you measure the length and just wrap it around. The coil loop is not the device! It is the antenna/speaker. Everybody is missing the driver and feedback. Most of the builds are trying to incorporate the driver, feedback and antenna in one stage of the device. Separate these out.

@GK,

So did this build output anything of substance or didn't you drive it with enough EMF Like Don does? From the looks of it the wire lengths look to be approx the same since it appears you wrapped the green wire about the speaker (stranded) wire which looks to be 1.5 turns around the wire spool.

Anyways, so the wire lengths are based on the resonance of the coils then, secondary rules and you wound the primary to be 1/4 wave or the secondaries resonant f ?

Is the speaker/stranded wire the output connection?

Also from your comments do you think it is possible the outer ring is nothing more that a 1:1 transformer?

I redrew what we have all seen. Tesla coils.
This is so clear. Alter the gauge or switch the pulsing coils.
Square waves create too high an impact to catch. All we see are sparks. But sine waves on the other hand resonate at one chosen frequency matching the coil inductance. So instead of spread spectrum we have a definable output which we can harvest with common materials and standard technology. You don't have to catch fields at certain angles or periods of skipping where windings touch at oblique angles. Clear? There is nothing new or strange about Smiths or Dollards configurations.

The miniature analog computer in the picture is 32 years old. It is an LMD TEM unit like in Dollard's video.
