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.

Hi pechkata,
Any news for very interesting investigations - why 3 pieces of this project work differently?

Hello Carl-NC
How can we program a time slot?
How can we build this type - time slot?
I tried but I can't do it.

Are you wanting to create a half-sine TX, or the Fisher Impulse TX? They are done differently.

Hello Carl-NC
Yes, but I don't know how this happens.
I would be very happy if you could draw a schematic.

[Carl-NC]

The half-sine is shown in Ch 26, you literally just add a series cap to the coil:



The Impulse TX requires shorting D1 & D2 so that flybacks are suppressed:

Hello Carl-NC
Thanks for the clarification.
What do we feed to the points?
What kind of impulse?
NCLK1
PCLK1
NCLK2
PCLK2

Hello NASCO
Is this your stimulator?

[N@SKO]

Yes ,I use Proteus

Hello Nasko, wouldn't it be better to use a mosfet driver from the TC4426/TC4427/TC4428 series instead of bss138 and bss84r? In this case, the signal from the chip should be low and high.
