Science project for class 8th students working model Easy science exhibition projects class

Welcome to RR Techs! In this video, we'll show you a simple yet effective DIY method to convert an old, non-working LED bulb into a new working LED light using a USB power source. If you've got an old LED bulb lying around, don't toss it out just yet! With a few basic steps, you can remove the old components inside the bulb, add a USB connection, and reuse the LED light inside.

We'll walk you through every step, from opening the bulb to removing the driver and other unnecessary parts. After that, we'll show you how to carefully connect the LED directly to a USB cable, making it an eco-friendly, low-cost lighting solution. You can power it using any USB source like a power bank, laptop, or even a phone charger!

This is a great project for anyone who enjoys DIY electronics, wants to reduce waste, or needs a quick portable light source.

What you'll need:

Old LED bulb
USB cable (from an old charger or device)
Basic tools like a screwdriver and wire cutter
Soldering kit (optional but recommended)
