Mysterious Resonant Circuit

@EM

I think the trannie was 2N2222A. Anyway, an interesting feature is that this trannie will act as a resonating negistor. (not OU, but a negistor, in that it draws less current with the higher voltage applied to the circuit.) I think I cam across it at JLNLabs (Naudin) website. I remember GK has a link on every post of his.

My thinking is this.... Say Poynts model is correct. So what? For the first section of the cycle, it IS OU. What you need to do, is pulse the overall circuit, with the time ranges of the pulses to HOLD it within the OU range. Pulsing the resonator, so to speak.

My thought is that the negistor circuit will provide both necessary voltage (gain with just one tranny, and you can link them in series for higher voltage with the same DC input voltage) and timing all in one tiny circuit (3 minimum components total). If you are interested, and it is not from JLN Labs, let me know and I will find it again (at that point anywhere from B. Beatty's site, to Rex or Bearden's...... but I think it was JLN).

Also, I have come across another SIMPLE OU device... 4 diodes, 4 caps, 100 feet of wire, that looks interesting. The problem is it only puts out microwatts of power... But hey, maybe it can be expanded upon to increase power! I will provide a link if anyone's interested.

I had an electronic experiment kit if I was 8 years old.
Built a nice amp with (dont know) there was a class A
output stage with a bc328, and an bf494 preamp - should
amplify something. I found out that if I tap the diode -
some potential current source - with my wet fingers
there was a quite fascinating random modulated tone
comming out the pieco earphone.
Did only work for an afternoon - but
want to have that again. Could have listened for hours.
Never did the same again. Maybe due to the weird
grounding in that house. far out.

Hi EM,
any news on your circuit ?
Any new measurements ?

Many thanks.

@EM

TPUbruce posted a video on youtube, and is claiming to have gotten your circuit self running. I will see if I can provide a direct link to the vid. He gave you credit for the invention. (Which I thought was right.)
