Giantkiller moves forward into Full Heterodyning.

[aleks]

In the simplest form it may look like an iron ring with a piezo-buzzer glued to it with epoxy. Buzzer's output side should point right into the metal. It is best if ring's circumference is matched to buzzer's self resonant frequency: this way it will be possible to pump in more energy per second (just remember that iron will ring for a pretty long time thus accumulating acoustic energy and entering into saturation and high non-linearity). Buzzer's obnoxious sound in this setup can be well isolated just by wrapping the ring and the buzzer into something rubbery (even an electrical insulation will help) - and this of course won't damage the required performance much (I mean internal acoustic energy accumulation).

Well, I hardly believe something "extra" will show-up here, but if we are talking about acoustical nature of the TPU, it should be explainable in a way close to what I wrote. Moreover, the effect should be replicatable with a piezo-buzzer: it's insane to try to achieve the same performance with EM induction: you can, but you'll waste a lot of energy.

I am going to catch the kick. It is at end of the ramp up which is over the supply voltage and which is the start of the runaway condition. Then use it as a pulse on another part of the coil. My idea of a delay is to fire the first coil 'A' to drive the ring in a Clockwise direction. Take that kick 'A' and pulse the preceding coil 'B' which is in the Counterclockwise position and so on to coi 'C' which fires 'A'. So looking down on the ring each coil is driven to produce a Clockwise thrust on the ring while the each coil drives the preceding coil. The thrust is pointed in the Clockwise direction while the coil sequencing is done in the Coounterclockwise direction. Can you see the vortex? Rotational pressure to create accumulative wave structure through heterodyning. Shweet!
The GK-E2Lego-PMH is a plug and play solution to this model.

Follow the trigger arrows and one can readily see how the coil the triggers the previous coil to get a flux pulse pushed up behind itself. Cannon balls. The kicker wave ends up in the center of the ring successively forming a swirling Rodin type Moire pattern. Even more heterodyning. No wonder the thing runs away. It scares itself to death.

Hi GK,

I'm not an electrical person by any stretch of the imagination, but I do fairly well with design and form.
When I 1st saw your diagram for coil driving, the 1st thing I thought of was this attached pic.

I'm not overly religious, but I have enough of a background in Christianity to have recognized the almost universal  trinity symbol.

It's little coincidences like this that makes me think that a lot of discovery, is rediscovery and the clues have been around us all the time.

Congratulations on your "kick" sir, and I hope your future experiments go well and safely.
I'll probably be paying a little more attention to this thread now

I diagd the trinary. But with the plug n play E2lego here I just snapped together a quad. 2 iron wire half circles, 4 coils, 2 magnets. Like Spider showed. With 4 coils the iron is heavily covered. I will use the xr2206 board, then the 555s. Just to see  the difference. I am in the middle of something right now but will be on this later.
The requirements are sines, squares 1 hz to 20khz. The mix of iron, copper, and steel have responded the best. I followed what some had posted about the materials. The iron model is the GK4 cut in half vertically. Now following the driving specs by still other posters to see what can be proven.

With the e2lego system It is like having a coil prototyping system. I just kept flipping parts around and then wham!.  Now there is no mystery. One can only learn to swim with water. I got water. I am waiting for someone else to build. This has been the quickest build yet.
So this first setup will be 2 iron halves, then add the iron bars, then add the air gaps.
And for major grins I coil drive only 1 iron half.
I basically am backtracking through the configurations because they all provided results. Better each time.

Hi Everyone,

I'll be joining in shortly. I couldn't find any steel for my core but I got lots
of other stuff today. Can't wait to get started. I got lots of goodies today.
About $300 and more to go I'm sure

@bhaas,
Hi, the steel wire comes from Hobby Lobby back in the bead and jewelry making. It is white or red. Just get a magnet pack from another aisle to test. Cheap too, .99 cents for 50 feet

I used the 22awg with the steel on the empty spools. But don't want to turn you away from any derivations of what you have in mind. Have fun.
