What happens when you get together 6 people, a banana suit, and some hardware? You get a really creative project known as the LED Wall. The crew built a giant LED Wall made up of a matrix of 350 LEDs. Over a weekend they painstakingly soldered and glued the lights to a pegboard and connected them together using MAX6953 LED driver chips. The result was a matrix of LEDs that they could control by turning each LED on and off like pixels. They took that a step further and connected the LED Wall to the Internet via the ioBridge IO-204. With a web interface, anyone can draw their own messages and send them to the LED Wall with a web browser. You can see your messages being displayed by watching the live video feed on LED Wall website. So far, 119700 pixels have been sent to the LED Wall through the web — everything from “Hello World” to Mario and Space Invaders have been submitted.
You can draw your own images on the LED Wall yourself and also look through other people’s messages by visiting the project website at wall.elnormo.net. If you visit the project site, you will also see how they created the LED Wall. Here’s a time-lapsed video of the project build.
