Some thoughts on how the TPU might work.

Hello all,

I think that this picture and the description is OK. Yes, you see only a 1 turn collector but who cares. And you see only a 1 segment control. Its easy to have 3 or 4 segments, no problem.

Do you see anything else??

Hello all,

its nice here: Quite!!

First I have to say that my new TPU is wound as in the picture. Its a nice TPU.

The last few days I was playing with my ECD 1 control TPU and as I already posted, at 245kHz + an additional frequency there is a pumping.

Yesterday I connected my new TPU on the oscillators and my 1. frequency was 245kHz. I wanted to see if I can have the same pumping with my TPU as I had it with my ECD.

I only can say yeeeeesssss!!!! 245kHz + a lower frequency gives me a pumping at arround 5 - 10Hz. The pumping is not stable because I have no feedback coils and everything is connected in a wrong way.

I have to print dfros words on a paper so I can have his words on my workbench.

Have a nice day.

Hello

I would say hello all but as Im allone I can only say

Hello myself

yesterday I had not much time but I worked on my 1 ECD coil TPU. As mentioned before, it seems that the 245kHz frequency is a "magic" frequency. I found no other frequency mix that gives me a pumping signal. So, 245kHz is needed and 2 other frequencies.

As I had my pumping I saw that the wires are a little vibrating and so I took a neodym magnet and placed it to the control coil. The vibration was much stronger.

Our master said "all arround..." and I streched the ECD control coil over a quarter of the circumference of my TPU. The wires vibrated.

That means that my new TPU is wound totally wrong because I have a pumping but NOT a vibration.

Its logic why I dont have a vibration and what I have to do: just to build my TPU like in the picture!!!!!!

Hope you are well.

Also, 258 is square root of 67k which is speed of Earth travel through space.
258 is not far from your 245.
Also 5607 is good.
I also like the 41 to 121 range mixes are so freaky sounding and have powerful vibrations.
I have tried in many places on the CC with a magnet at the end also to check the vibrations.

@all or @z_p_e

On the large TPU he has two yellow caps that remind me of crossover capacitors for audio. From your experience on the size of those caps, are they generally used for low frequency woofer, midrange or for a high frequency tweeter?

@wattsup

Im OK, thanks.

Now I remember. Yesterday I measured the 67kHz.
