How to Build Your Own Metal Detector

FFWA7Z2IBYX625C MEDIUM

Check out this super fun project tutorial from Aleator777 on instructables!

Why not uncover the lost of treasures of bygone civilizations, (or perhaps forgotten goods from a beachside party) with your very own metal detector? In this Instructable, I’ll show you how to build a metal detector that not only sounds when you’ve discovered something, but lights up as well! Using a handful of basic components and the Intel Edison, we’ll build a basic detector capable of sensing metals of many sorts. You never know what valuables might be beneath your own feet…

Adafruit DotStar Digital LED Strip – Black 144 LED/m – One Meter – BLACK: Move over NeoPixels, there’s a new LED strip in town! These fancy new DotStar LED strips are a great upgrade for people who have loved and used NeoPixel strips for a few years but want something even better. DotStar LEDs use generic 2-wire SPI, so you can push data much faster than with the NeoPixel 800 KHz protocol and there’s no specific timing required. They also have much higher PWM refresh rates, so you can do Persistence-of-Vision (POV) and have less flickering, particularly at low brightness levels. (read more)



Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
