The other day when I was searching instructables I come across on interesting and simple circuit for metal detector. It is build with 555 coil and few other components. Instructable that inspire me...

This Wireless metal detector robot circuit is designed using 8051 microcontroller and is mainly used to detect landmines, minerals, weapons, etc.

Most metal detectors use a search coil that act as part of an oscillator circuit. When metal is put in proximity of the search coil both the frequency of the oscillation changes. Many metal detecto...

This metal detector can detect metal as well as magnets. When a piece of metal or magnet is brought close to the inductor/choke the output frequency changes and you can hear sound from the speaker....

This is a simple metal detector circuit, Can find various metal and adjustable sensitivity Easy to use to place near metal. The circuit inside include a few components has IC-NE556 is at the heart ...

A metal detector is an electronic instrument which detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried under...
