Introduction: LED Pixel Cube
Really, we did this.
Step 1: What You Need
- 2032 coin cell battery
- white LED
- neodymium magnet
- plastic container
- tracing paper
- X-acto blade or other cutting tool
- super glue (not pictured)
- hot glue (not pictured)
Step 2: The Screen
To make the end of the box glow, it needs a translucent coating. Tracing paper is perfect for this and easy to apply. Just cut out the square to the same size. This is easily done by putting the container on the paper and cutting with a razor.
With the square ready, apply tiny dabs of super glue on the corners of the box and press the paper down onto it.
Step 3: Add Magnet
To secure the magnet to the bottom, apply some hot glue inside on of the corners of the containers lid. Then drop the magnet on top and place other magnets underneath it to pull the interior magnet flush against the lid.
Step 4: Prepping the LED and Battery
Put the LED onto the battery. If it didn't light up, just flip the LED over.
Good, now the next step is to bend the LED so that the LED is facing up towards the anode (-) side. In other words, the flat side of the battery is down and the curved side is up.
With that set, tightly wrap electrical tape around it a few times.
Step 5: Put It All Together
Almost done. Drop the battery/LED combo on top of the magnet and it will be stuck together. Now just attach the body of the container and it's lit up!
If the LED is off center, just remove the lid and adjust the LED direction until you're happy with it.
That's it! Enjoy.
