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 ...

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 ...

A traditional early project for someone discovering a love for electronics has been for many years a metal detector. This would mean a few transistors back in the day, but today it’s more likely to ...

Designed and implemented a basic metal detector circuit based on the principle of inductive proximity sensing. The system uses an LC oscillator circuit to detect variations in inductance caused by the ...

A metal detector is an instrument that detects the nearby presence of metal. These devices are useful for finding metal objects on the surface, underground, and even underwater. A display can be ...
