P.S.

has anoybody taken a look a wikapedias, transformer basics?  there seem to be lots of warnings about "kicks"

Hello all,

Nostradam

I fully agree. I think that only the length of wire is important. If the wire is long and the frequency low (say 7..Hz the electrons are trawelling longer then in short wires with say 5000 Hz.

By the way, my TPU was working with 2 frequencies and I had very good results. There was a very, very STRONG rotational magnetic field. The control coils were connected in one piece (no segments). One resonant frequency was 6-8 Hz and the other around 5000 Hz BUT my control coils were wound vertical as tao showed us (thanks tao) and one coil horizontal around the circunference. I pulsed one coil with 6-8 Hz and the other with 5000 Hz. I can tell you, that was amazing.
As many time before I throw my TPU away! I was not satisfied! Dont say I?m crazy but I feel that something with my TPU was wrong. I?m winding a new TPU ( the 4th) and I think it will be better.
This is the reason why I?m buing today a oscilloskop. It will be used but with 100 Mz very good for me. Don?t think I have money but to finish this project with success I need the scope.

Hello all,

ctglabs

I had 1 vertical and 1 horizontal coil pulsed with 2 frequencies. The interesting thing was that I put one little magnet OUTSIDE the TPU, so to say, on the right side and an other magnet on the left side and as I changed the frequency in one moment vibrated the right magnet and when I changed the frequency again the left magnet vibrated and again at another frequency both magnets vibrated. The distance between the magnets and the TPU was 1 inch. The hight of the magnetic field was 1 feet (35 cm). I measured it. Inside the TPU, as I changed the frequency, my magnetic needle was spinning horizontally or, when I changed the frequency, vertically.  It seems to me that we can do a lot of things by just playing with frequencies. Sorry, don?t ask me the frequencies because in this moment I have no scope.

Hi Otto,

Of course an oscilloscope is the best for checking waveforms etc  but maybe for measuring the frequencies you may borrow from your friends' circle a digital multimeter with frequncy measurement function?  Just an idea...
Maybe a university or college lab near to you could be also of help in giving you meas. instrument, I wonder. I know it is not easy to beg around...
