Kapanadze Cousin - DALLY FREE ENERGY

[verpies]

I managed to power up the completed device without the AT PSU before I'm away from the bench. Nothing special was observed during tuning with various caps across L2 and adjustment of VCO and no rise in output voltage on any winding. I'm not happy about the nano interface to the co-ax driver transistor as distortion of the pulse is visible at the collector. The nano with output disconnected produces clean sharp pulses. A ground earth was also applied as per schematic.

What is the amplitude of your nanopulser's output?
Also what is its rise time, pulse width and PRF ?

That's a good formula if you know the dimensions and inductance L.
From my experience, L at 10kHz is very different than L at 10MHz.  I don't even try to measure at GHz...

Thanks for the comment, it is important.
Generally accepted in many devices to measure the inductance of a standard frequency - 1 kHz. Difference inductance at higher frequencies - associated with measuring capacitance of coil, core, etc.
Therefore, the standard measurements used  the same frequency - 1 kHz, to avoid symptoms of parasitic capacitances, because this device, in fact measures the total impedance of the reactive elements, so there is a difference.
At 1 kHz the parasitic capacitance is not manifested and the accuracy of measurements obtained high.

P.S.You have not offended me. Don't hesitate to disagree with me, if you think that I am wrong.

OK!

I suggest a table to compare types of digital integrated circuits
(for nano pulser)
I think, Dally not correctly indicated the replacement of ICs

Wow!, I didn't think that such compilation of Russian and foreign logic families existed. Very useful stuff.

BTW: What russian forum has the latest news on Dally's v2 device?

Is there a way to build up to a voltage and then have that voltage released?


Like a zener will reverse at say 3.3, but it will still be a 3.3v drop in the current... is there something that can build up to say 4.5V then have a voltage drop of 0.7 until the input is less than 0.7?
