This simple BFO metal detector requires only a few of components and an evening's work. The two oscillators are simple Colpitts designs using BJT transistors. The reference oscillator's frequency is approximately 370kHz, slightly tunable with the help of a silicon varactor diode. The outputs of the two oscillators are fed to a mixer made with ...

A metal detector circuit is an electronic circuitry that can detect the presence of a nearby metal object. It's largely used in the security and industrial sectors to identify the presence of metal objects in otherwise non-metallic materials. A simple metal detector circuit can be constructed using a few components and some basic electrical knowledge.
