Hello all,

@Phantasm

my cores are made with copper pipes. Diameter is 1/2" or 12mm. I would love to have this pipes in a bigger diameter but...

They are used in heating systems, water supplies......cheap.

I also wanted to buy a plate of copper but .....Im not soooo rich.

Yes, i noticed also that black, or dark core material in a 15 inch TPU cutaway.
I remember too, that SM told about frequesies something like that : "The best thing with a 35 kHz frequency is that i can not hear it"   ; the device was acoustic and acoustic wave was generated by magnetostrictive / electrostrictive effect.

You certainly could be right - but with SM's tale of the exploding TV, we should have the principals necessary for TPU function within the the operation of that television.

Logically, if the magnetostrictive / electrostrictive effect is a component of TPU functionality we should see this effect in the design of the TV as well.

Were the toroids in those TV's conducive to this effect? What material was used for them?

Again, I dont want to discount the validity of Acoustomagnetics but if the effect takes place in those TV's we should be able to harness it in a TPU with similar materials.

Personally, I think we're dealing with the same core material used in toroids in VHF applications. The flux needs to be able to dissipate quickly to accommodate our high frequencies so the material must be "Soft" in the magnetic sense. Otto, is this why you chose copper? I cannot find very much information about using copper toroids...

Although if you wanted to use custom cores with the intention of utilizing mametostrictive / electrostirctive effects, you'd likely get results utilizing that effect as well

Hello all,

@Phantasm

I tried to use iron powder cores taken from TV deflection systems. I pulsed them and with 24V/5A I managed to light a 100W bulb with full light. The cores, hot, the MOSFETs very hot.

Then I got a lot of best quality Metglas and used this as a core. No reaction, to say so. The Metglas core didnt work.

Now Im using a copper pipe as a core. Its the best!!

SM told us in his way to use Copper and Alumimium in our TPUs but nobody is listening.

Its clear ( at least for me) that various plastics also can work in a TPU but I dont want to work with plastics because my copper core is a real beauty.

I think that iron resists to much to the flow of the particles. They are somehow penetrating the iron powder core.

Totally different is it when you use Metglas as a core. The particles are only striving over this metal and nothing happens.

Copper is between the mentioned 2 metals. When I short the core I see nice sparcs. This doesnt happen with iron powder but happens with Metglas. Not sooo strong as with copper but still to see.

PS: is here a TPU builder that listens or Im wrighting for nothing???  Heeeeeyyyyy, GK, Roberto....
