Here, we are going to build small circuit named metal detector circuit which is used to check the persons in shopping malls, cinema halls, etc. to ensure that person is not carrying any explosive ...

In a metal like copper, however, the outer electrons swim around freely and are shared by all the atoms. That’s why ...

[mircemk] is quite a wizard when it comes to using coils of wires in projects, especially when their application is within easy-to-build metal detectors. There are all kinds of ways to send signals ...

The project is designed to develop a robotic vehicle that can sense metals ahead of it on its path similar to sensing land mines. The robot is controlled by a remote android application. The project ...

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 ...
