Bipolar PI design

Greetings to all...

It makes sense.
In the previous videos you saw the behavior on coins.
It always behaves the same.
You didn't tell me your opinion about the voltage?
Is that how it should act?
I still have doubts about the quality and originality of these TL072s.

I glued 3 pieces of circuit board.
All three work differently.
One of them works like yours.

I can't tell from the voltmeter, too hard to see. An oscope trace will tell you quickly.

That's interesting to investigate!

I'll do that next time I sit to deal with it.
