3 Ways to Build a Metal Detector - wikiHow

Jul 31, 2019 · To build a metal detector, start by getting a portable AM/FM radio and a calculator. Then, tune the radio to the highest band on the AM setting. Next, turn on the calculator and position the radio and calculator back to back until you hear a steady, dull tone. Once you hear the tone, tape the devices together and attach them to a broomstick or ...

Simple Metal Detector Circuit - electroschematics

The metal detector circuit shown here must represent the limits of simplicity for a metal detector, yet the design works surprisingly well. It uses just one 40106 hex Schmitt inverter IC, a capacitor and a search coil – and of course the batteries. A lead from IC1b pin 4 needs to be attached to a medium wave radio aerial, or it should be ...
