DIY Detector de Metales/DIY metal detector

Arduino DIY metal detector. DIY Metal Detector / DIY metal detector Some time ago I recorded a video about some Russian homemade metal detectors that work with pulse induction technology.  I tell you, we are going to choose 2 metal detectors to build. One is with VLF technology that can discriminate metals but more difficult to do  and the other is a metal detector with pulse induction technology.  First let's see how the two versions work and then  I will explain how this metal detector work. I already have video on how to make the version with Arduino, only part is missing where I explain how to adjust it ▶Part 1:   • Hacemos un detector de metales Spirit Pi 4...   ▶Part 2:   • Hacemos un detector de metales Spirit Pi 4...   ▶Part 3:   • Hacemos un detector de metales Spirit Pi 4...   ▶Part 4:   • Detector de metales casero Spirit Pi 4 Pro...   ▶Mi pagina web y mas proyectos: https://neco-desarrollo.es ▶Support me on Patreon:https://www.patreon.com/bePatron?u=19... ▶Support me on PayPal: https://www.paypal.com/cgi-bin/webscr... #SpiritPI#DetectorDeMetalesPI
