In this video, I assemble and solder a metal detector PCB kit that I purchased from a four-letter online store. I walk through the entire build process — placing every component, soldering the board, and completing the final assembly. The metal detector works smoothly and gives clear buzzer alerts when detecting gold, iron, and various other metals. 🔧⚡️ This is a great hands-on project for anyone interested in PCB kits, soldering practice, or DIY electronics.
