DIY Metal Detector Welding Practice Plate Kit

The DIY Metal Detector Welding Practice Plate Kit is a beginner-friendly electronics soldering project that allows users to assemble their own functional metal detector from individual electronic components. This educational kit is designed to teach the fundamentals of soldering, component identification, and basic electronic circuit assembly in a simple and practical way.

The kit includes all required components such as resistors, capacitors, transistors, diodes, buzzer, LED indicators, PCB board, and the detection coil integrated into the PCB. Once assembled, the device can detect metallic objects within a range of up to 60mm and provides both sound and light alarms when metal is detected.

Operating from a low 3V–5V DC power supply, the detector consumes minimal power and is safe for learning and experimentation. The PCB layout is clearly marked for easy assembly, making it suitable even for users with no prior soldering experience.

This kit is ideal for students, hobbyists, STEM learning activities, and DIY electronics enthusiasts looking for a fun and educational project. It can also be used outdoors to detect coins or small metal objects near the surface.
