Today, dear brothers, we are making together a metal detector consisting of 3 transistors, as I found the circuit simple and easy, so I wanted goodness to spread to the honorable brothers. This detector consists of a capacitor 104, the value of which is 100 nanofarad, in addition to a resistance of 1 kilo, a resistance of 33 ohms, a resistance of 22 kilos, a resistance of 47 kilos, and a resistance 5 kg variable, in addition to a file and a headset.

The transistor used in the experiment is c1815, and we can replace it with the bc547:

Let's get acquainted with the manufacture of this device through the image of the circuit:




Now let's get to know the circle closely through the experiment in the video:
