Description:
This is a DIY metal detector parts kit. You need to solder it yourself.
The Metal Detector DIY soldering kit is a great way to get into electronics and have fun in the process. With this kit, even the most novice of electronics hobbyists can build their very own metal detectors. All of the components required to build the metal detector are included in the kit, such as the PCB, transistors, capacitors, resistors, diodes, and the PCB-coil. Everything is organized for easy assembly and includes a detailed schematic. The kit can be used to detect metal objects buried in the earth or to detect coins and metals on the beach.
This DIY soldering kit is intended for those who have no prior experience in electronics or soldering. The board included in the kit is designed to be easy to assemble and requires no special tools. The project can be completed in less than an hour and is great for those just getting started in the hobby. It is also a great way to learn the basics of soldering and discrete electronics.
The metal detector can be used outdoors to detect metal objects buried in the earth or underground. The sensitivity of the detector can be adjusted so that it can detect objects at different depths. The kit includes a buzzer and LED indicator that will notify when an object is detected.
With this kit, you can create a reliable and affordable metal detector that you can use for a variety of applications. It is also a great way to spend time outdoors and explore the natural world around you. The Metal Detector DIY soldering kit makes a great gift for any electronics enthusiast or hobbyist.
A power supply of 3-5V is required, and the operating current is about 40mA.
The PCB with the antenna measures 86 x 61mm and the detection range can be up to 60mm.
The included instructions are in Chinese. But matching the parts in the bag with their locations on the PCB does not require any instructions.
Hint: The Translate app on your phone can translate an image of the instruction sheet into any language you want.
