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, making sure you never miss anything valuable.
Watch the videos below to learn more about the eco-friendly Arduino metal detector which has been created by TechKiwiGadgets who has kindly provided full instructions and component lists via the Instructable website via the link below.
TechKiwiGadgets explains more about the inspiration behind the Arduino DIY metal detector and the technology used :
While using a metal detector to find valuable jewelry, and less valuable aluminum cans, can be interesting, the more accurately you can pinpoint the “treasure,” the easier it is. For excellent accuracy while maintaining a wide sensing field, Maker “TechKiwiGadgets” built a detector with not one, but four sets of sensing coils, all controlled using an Arduino Mega.
The device generates and senses a magnetic pulse from each set of coils, which is modified if there is a metallic object present. In search mode, the four signals are combined into a single display, and once an object is located, the four sensors can be shown in a split-screen. You can then dig where, and only where, it’s needed, minimizing work and your environmental impact!
