    your fatal mistake is you connect Output and Input of the 2940 on power supply. your 2940 will give off the magic smoke living in electronics.

    • PI detector with mono coil -correct discrimination for silver is not possible.

      • I can assure you that my this drawing is correct, because I was being used, or you didn't notice the zener diode has a 5.6V LM7905 below, it is because of the diode, the negative 5V into negative 10.6V

ID:	340810The drawings I have some ideas that, if you use LM7910, then you output voltage 10.6V or 10V only, 10V only about 9.4 volts, this is the first question, the second question is a 7660 boost part is wrong, the third one is the U3 fourteenth adjustable foot is wrong connection, please see U2

                  • We need to know first how battery is here oriented.
                    Where is + an where is - ? Georgi?
                    There are different use of + - battery sign in schematics drawing.

                    Which one is correct, this: - -|i|i-+ or this: + -|i|i- - ? According C10 + is at bottom.




                    What is (+-) marking convention - look at praxis:

ID:	340814The plan is entirely correct, this circuit is based on +12V GND
