A new Instructables page has been created to make an eco-friendly DIY metal detector using an Arduino Mega just been combined with a 3.2 inch TFT LCD touchscreen to provide a fantastic readout ...

With this simple project, which requires only about $40 and one hour, you could build your own EMI detector and start using it to save on your energy bills.

And, of course, with an Arduino and some know-how it’s possible to build a metal detector that has every feature you could want from even a commercial offering.

The Arduino samples the peak detector’s output and calculates the original pulse’s amplitude. Their webpage has copious details on where to get the parts, the software and how to make it.

Professional metal detectors are simple, but require a bit of work to make. But you can build a pared-down handheld detector using a calculator, an AM/FM radio and some masking tape.

Connect the leftmost pin of the detector to Arduino Digital pin 2, the middle pin to Ground, and the rightmost pin to +3.3V. 3. Plug in the 2N3904 NPN transistor. Make sure the flat side is facing ...

One of the essential parts of any home security system is a door detector that lets you know when a door opens. Over on Adafruit, they show you how to build your own that hooks into IFTTT so you ...
