Join us on an exciting DIY adventure as we build a homemade metal detector from scratch! 🛠️ Watch the full process of crafting this handy device and see what hidden treasures we uncover along ...

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 ...

If your system's signal processing requirements in-clude peak detection and amplification, consider a simple circuit that will satisfy both needs and save hardware. The single ...

Interestingly, most of the electronics were a small disguised AM radio. BTW, one of the cleverest circuit for an 8pin PIC I ever saw was a metal detector using an LC connected to its external ...

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.
