Build Your Own Electronic Component Tester – A Complete Guide (For Beginners & Engineering Students)
1. Introduction – Why You Need This Tester (And Why You Should Build It Yourself) Let me tell you a quick story. Ten years ago, I was a broke engineering student. I found a box of old components at a scrap shop – transistors, ICs, capacitors, all without any labels. I had no idea what anything was. I tried testing them with a multimeter. Guess what happened? I shorted three transistors, blew an LED, and almost set my table on fire. That day, I decided I needed a component tester . I looked online. The good ones cost ₹3000-5000. Too expensive. The cheap ones (₹800) were useless – they gave wrong readings and broke within a month. So I built my own. And today, I'm going to teach you how to build your own electronic component tester for just ₹500-800 💡 This project is great for people who are just starting out students who like electronics, people who like to tinker with things and anyone who likes to do things themselves. It is also good for DIY lo...
