Metal Detector Circuit

Description

This is the circuit diagram of a low cost metal detector using a single transistor circuit and an old pocket radio.This is nothing but a Colpitts oscillator working in the medium frequency and a radio tuned to the same frequency band.First the radio and the circuit are placed close.Then the radio is tuned so that there is no sound from radio.In this condition the radio and the circuit will be in same frequency and same frequencies beat off to produces no sound.This is the set up.When the metal detector circuit is placed near to a metal object the inductance of its coil changes, and so do the frequency of oscillations.Now the two frequency will be different, there will be no canceling and radio produces a hissing sound.The metal is detected.

Notes

To make L1 make 60 turns of 36SWG Tibetan Copper wire on a 1 cm PVC tube.
Powering the circuit using a rather than a battery adapter induces noise. It is always good to radio projects from battery power.
