Fresh off the 72-hour madness of the Red Bull Creation contest some of the folks a North Street Labs took on a stage lighting project. It’s for a local performing venue that just opened up, and despite the time crunch the team pulled off another great build.
Sixteen meters of LED strip make the electronics for the project a whole lot easier. The strips run up the center of a cabinets built as stand-alone columns which will end up at the back of the stage. Each cabinet has its own 5V 4A power supply (note the burnout issues they mention when using cheap eBay PSUs). Each column has its own Arduino Uno driving the LEDs, with an RS485 shield to connect back to a main Arduino Mega 2560 controller. It uses a PSX controller to switch between different lighting modes.
The seven towers boasting 688 LEDs isn’t all that’s shedding light on the show. There’s also about 300 feet of EL wire at work.
