Circuit Diy Metal Detector. The inductor of the above tank circuit forms the detector of the metal detector a large coil of wire. A metal detector works by bringing some conductive material into the inside of a coil and changing the characteristics of the coil in the process the coil of a metal detector is large so that you can test a larger area.

The metal detector is built with one 100µh coil that has 40 mm in diameter and is made of 50 turns 0 4 mm wire. These metal detector circuits are being used in plenty of places. This changes the magnetic permeability of the inductor s core causing the inductance to change.
The velleman k7102 metal detector project.
To build this diy metal detector you need velleman k7102 kit solder a buzzer a 9v battery and some tools. There are instructions to help you solder the components in place and do everything from making the coils to testing the detector. Most metal detectors uses a search coil that act as part of an oscillator circuit. The heart of this diy metal detector circuit is the cs209a ic.
