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 po… ...
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 ...
The emerging analog matrix computing technology based on memristive crossbar array (MCA) constitutes a revolutionary new computational paradigm applicable to a wide range of domains. Despite the ...
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 ...
Unfortunately, no. It wasn’t a technical failure though; the metal detector did appear to work, although it took a pretty sizable object to set it off.
