Specification

Description

An old pocket radio and a single transistor circuit is used to build this low-cost metal detector. This Electronic Metal Detector DIY Kit is nothing but a Colpitts oscillator working in the medium band frequency and a radio tuned to the same frequency. First, the radio and the circuit are placed close. Then the radio is turned OFF so that there is no sound from the radio. In this condition, the radio and the circuit will be in the same frequency and the same frequencies beat off to produce no sound.

When the metal detector circuit is placed near a metal object the inductance of its coil changes, and so does the frequency of oscillations. Now the two frequencies will be different, there will be no cancelling, and the radio produces a hissing sound. Hence, the metal is detected.
