MrA ..

Naaa .. just take a toke and pass it on buddy

Roll your own coils if you like

Isn't it interesting that daniels member number is 666.

Roll your own coils,, Now thats funny.!. way  way of topic, But funny.

And what was the topic? oh yeah Coils/ the TPU kind,, and it is NOT, OU. the tpu is nothing more than a niffy antenna.

I have been reading in these forums for some time. I,, like most of you am positive that this device can and has been built. I am having timing issues with mine. Could we all return to the topic and disguess coils and timing the pulse? There are many Brilliant minds in these forums. Many have years of experience in the "field" (Pun intended.) Lets use this recourse and share in it so we can all Benefit form the outcome.

Hello all,

guys you are great!!! So much informations!!

Stefan,
you dont need to wright in German and  in English. Thanks anyway. Im using the IRF 840 MOSFETs in this moment. I tried the IRF 730 and they are ok too.

Yesterday and this morning before work I was mixing the frequencies and saw a lot of strange things:
With my setup, when I pulse only the top control coil with 30-40kHz I have on my scope over 200Vpp and my 60W bulb is, so to say, at half brightness.
If I pulse only my middle control coil with 70-80kHz I have on my scope pulses over 150Vpp
Pulsing only my bottom control coil I have pulses under 50Vpp.
This pulses I measure on the collector.
When I mix the 3 frequencies I have a lot of harmonics. Of course, I did not light my bulb at full brightness but in the range of 700-800mA I have a much better light then in my last post. Im getting better every day. I need only a few watts to get full brightness!!
Twice it happened I heard a loud hum noise from my TPU!! I KNOW this was the right frequency mix but I lost this hum because I tried to change a little my frequency!! Today my friend will give me 3 multiturn potentiometers 10k that I use in my oscillators for changing the frequencies. In this way I can change the frequencies much better.
In my setup I dont use diodes, resistors...nothing, only my coils.

Spherenot,

I think searching an unknown effect by using software/simulation is sensless (someone mentioned this already).

Your posted, combined waveform is surely mathematically perfect calculated, but you can not see other sideeffects like reflected pulses or something else what happend when you mix 3 freqs with independed, but well coupled coils.

The outputcoil of "a TPU" is also placed 90 degrees to the exiting coils, maybe this cause other unknown effects which will not be simulated by your wave-editor program.
