The folks at The Quad Cities Collaboration and Hackerspace (QC Co-Lab) were trying to find something to build for their first big project, and had to look no further than the wall for inspiration. The north end of their facility is home to a huge 15×17 glass block wall that happens to face a well-traveled roadway.

They decided that turning the wall into a huge LED display would be a great way to attract attention from passers-by, so they picked up some GE Color Effects lights and got down to business. Once they found out that the technical college next door was putting on an open house, the race was on to get the light display assembled as quickly as possible to maximize their exposure.

The team mounted the 255 LEDs in vacuum-formed reflective cones, which were attached to wooden frames before being installed behind the glass wall. An Arduino drives the entire display at a smooth 30 frames per second, a task they say tests the very limits of the board’s capabilities.

They finished the job in time for the open house, and as you can see in the video below, the display looks great.

Nice job QC-Co-Lab!
