The project uses the Arduino IDE and a Blue Pill STM32 module. The project looks good with an LED module and a rotary encoder to set sensitivity. Pulse induction metal detectors use a single coil ...

There are other metal detector projects using AVR and PIC. This one is nice and simple. I do wonder why the 7.64khz frequency was chosen instead of something in the 15k to 20k range wasn’t used.

This is an Arduino project called Fruit Detector. The idea behind the project is pretty basic. Different fruits have different resistances. The fruits can be told apart by their different resistance ...

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 ...

A line of InGaAs laser and detector modules is intended for use in Optical Time Domain Reflectometer (OTDR) mainframe and portable test equipment. For portable applications, seven MQW-FP laser ...

Using the power of Arduino, Evan Kale has ingeniously transformed a weed wacker into an Arduino-powered metal detector. This innovative project showcases the versatility and potential of Arduino ...

A "first of its kind" discovery was made in the Netherlands with the finding of an ancient Viking weapon. A fragment of a a 10th-century sword was discovered with the help of a metal detector.

Building an Arduino lie detector test This one caught my eye - an Arduino-based lie detector that can measure the skin's response to a question. At the heart of this project is an Arduino Nano, based ...

The system here uses a cheap Arduino board, a few sensors, and a magnetic contact switch. It’s then hooked into the Adafruit IO and connected to IFTTT, so you can set up alerts in any way you like.

"The Metal Detector" follows them all on this journey. "There's a German word that I learned over the course of making this film, which is erinnerungskultur , which means 'culture of remembrance ...
