I simulated the 741 power supply circuit of SASCHO2 on the computer, the two voltages are 12V and 12.9V respectively, I don't know why it doesn't have a 5V circuit

sometimes simulate doesn't work correct.

what software you using for drawing schematic and PCB ?

[ZOUjiarui]

proteus

[aft_72005]

proteus

only +12 , -12 symmetrical power section draw with proteus ..... but my opinion was other section ... for drawing main circuit and PCB what program you used ?

[ZOUjiarui]

No, I didn't draw. gold scan 4 is better than sbg

Who draw this PCB ?

Did you make Gold Scan 4?

And a sascho1.

who drew this schematic ?

Pulse induction motion detector.Ground balance and meter discrimination.Discrimination is possible best for PI detector with one coil.[ATTACH]46021[/ATTACH]

Hi Sascho ..

after long time .. I visit this post … seem as interesting and I will study circuit ..for it thanks

Hi Sascho,

I agree with Aft_72005. Interesting simple circuit. I'm wondering how does the discrimination part of the circuit actually works? Or maybe someone else here explain it?

Hi
power supply simulation .

Everything between C1 and R20,R23... doesn't make any sense.
