Introduction

Ever wondered how to light up your surroundings in a fun, creative way? Say hello to DIY LED Throwies! These magnetic LED lights are perfect for adding a splash of light to any metallic surface. Whether for events, art installations, or just some creative fun, this project is easy, affordable, and a great way to explore basic electronics. Let’s dive in!

What Are LED Throwies?

LED Throwies are small, self-contained magnetic LED lights that can stick to metallic surfaces. They’re created by attaching a battery, an LED, and a magnet together. Popular for creative street art, decorations, and even educational projects, they’re an excellent way to experiment with electronics and creativity.

Materials Needed

Here’s a checklist of materials you’ll need for this project:

  • LEDs: Any color of your choice (5mm recommended).
  • CR2032 Batteries: Reliable and long-lasting.
  • Neodymium Magnets: Strong and lightweight.
  • Adhesive Tape: Transparent or electrical tape for securing components.

Step-by-Step Guide to Making LED Throwies

1. Test the LED and Battery

Start by testing your LED. Attach the longer leg (positive) of the LED to the positive side of the battery. The LED should light up. If not, flip the LED legs and try again.

2. Attach the Magnet

Take a small neodymium magnet and place it on the negative side of the battery. Ensure it’s firmly attached.

3. Secure the LED

Wrap adhesive tape around the LED legs and the battery to secure the connection. Ensure the LED remains lit throughout this process.

4. Add Personal Touches

Customize your throwies with paint, stickers, or designs. This adds a unique flair to your creations.

5. Test and Deploy

Once completed, throw your LED Throwies onto any metallic surface and watch them stick and shine!
