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 ...

[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 ...

DSP hardware from Buckinghamshire-based Sundance Multiprocessor Technology was used in Qinetiq‘s Portable Humanitarian Mine Detector (PHMD) project. “They have never allowed us to reveal this before,” ...

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 ...
