Steven Marks secret

@rensseak

thanks a lot. I will try it. If you also want to build it you have to change the cap 10nF or the other ot both or use just 1 with 470pF.

tach Otto,

demnächst kommt ein kleines Paket von Conrad    bei mir an, dann kanns losgehen. Allerdings baue ich mir die Teile mit Sechsfachschalter und die Kondensatoren habe ich so wie in deiner Schaltung gewählt (4,7µF - 470nF - 47nF - 4,7nF und die letzten beiden mit 470pF u. 47pF). Die 1k Widerstände habe ich mit 2k5 Potis ersetzt um etwas feiner einstellen können. Bei dieser Gelegenheit noch ne Frage, muß es ein Edding sein.

@all

there is nothing special what i wrote, sorry

do you see ripple on falling slope of square wave signal at mosfet ? disruptive discharge ?

OMG the secret has been revealed .... NOT !

The TPU will die soon enough , I can feel it . This is the final speculative bubble before the big crash .

woof! woof ! ^%^&%&!! woof!

Hi Otto
I need to ask you agian what this circuit does so you can claim that you solved the TPU secret?

Hello all,

@nvisser

at a frequensy at say 250kHz the "show" starts: very slow collapses. In the first moment when I saw it, I touhgt a capacitor is discharged into the coils, but there was no cap connected!
Then I tuned the frequency to a lower value and the frequency of the collapses rised. I never saw this before.
Then I connected a 2. oscillator and a 2. MOSFET to try it with 2 frequencies.

And then I was "clever" and used 2 frequencies of the same value. Veeeery nice. I knew that there could be a disaster, but I was not fast enough. The output resistors of my 2 oscillators are blown.

After I fixed them I was working a lot on the frequencies, made a lot of setups.....and the I found something that I DONT WANT to post.

Its on you all to find out what I saw.

I have now really not much time so ....tomorrow.

Otto
