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 ...

The metal detector electronics were connected to make the correct circuit using wire and metal solder. We used a plastic sheet to map out our circuit board.

The metal detector comes to us from [mircemk] who is known for building simple yet effective metal detectors. Unlike his previous builds, this one uses only a single integrated circuit, the TL804 ...

A metal detector used to be an entirely analogue instrument, an oscillator whose frequency changed with the inductance of its sense coil when a piece of metal approached.

Admins of walk-through Garrett Metal detectors are urged to upgrade their iC Module CMA software to the latest available version to resolve these vulnerabilities.

The new amperometric detector from Metrohm excels by its high selectivity and measurement sensitivity. It can be used for sensitive and accurate determination of concentrations down to the ng/L-range.

The tiny LTC5597 RMS power-detector IC developed by Analog Devices provides accurate, full specified performance up to 70 GHz over a 35-dB dynamic range.

A while ago I bought this non-contact metal detector module from an online store to see how it functions, and what I need to build it. The cheap module I received from China had no instruction manual ...
