How to make a Long Range Metal Detector using Transistor || Science Project || SKR Electronics Lab

Hello everyone, and welcome to our channel! In this video, we'll show you how to make a metal detector using just 2 NPN transistors and a few other electronics components. It's a fascinating project that you can easily build with readily available materials. For this project, you'll need the following components: ⦿ 2 BC547 transistors ⦿ 102 pF capacitor ⦿ 22 pF capacitor ⦿ 100K potentiometer ⦿ 1K resistor ⦿ 5V buzzer ⦿ 0.32mm insulated copper wire ⦿ Push-on/off switch ⦿ 3.7V battery --------------------------------------------------------------------- 🔘Here's how it works: When the metal detector comes close to a metal object, it disturbs the magnetic field around it. The disturbance alters the resonance frequency of the oscillator circuit. As a result, the oscillator produces a varying signal, which is detected by the transistors. The detected signal is then amplified and sent to the buzzer, which produces an audible sound to indicate the presence of metal. By adjusting the potentiometer, you can fine-tune the sensitivity of the metal detector according to your requirements. Our step-by-step instructions will guide you through the entire process of building the metal detector. Whether you're a beginner or an electronics enthusiast, this project is perfect for learning and experimentation. So gather your components, grab your tools, and let's dive into the exciting world of metal detection with this DIY project. Let's get started! --------------------------------------------------------------------- 🔘 Social media Link :- ⚫Instagram:-   / skr_electronics_lab   --------------------------------------------------------------------- If you enjoyed this video, please like, share, and subscribe for more awesome content.
