It’s very simple to implement a valid metal detector with good performances. Very often people lose their metal objects at the beach or in the countryside. Coins, rings and necklaces disappear when ...

Looking for a light project to teach young hackers some very basic electronics? Here’s a quick and easy weekend project, a simple metal detector! We all know 555 timers are very useful and pop up in a ...

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 ...

We spent weeks testing the best metal detectors on the market. Here are our top six picks. Purchasing one of the best metal ...

Armed with metal detectors, curious explorers are finding historical objects every day. For example, Bob Podhrasky, COO, senior vice president, and director of engineering at metal detector ...

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. [Łukasz Podkalicki] shows us ...
