EMS Labs decided to give Jay Clegg’s excellent Peggy video hack a go and documented the results. The updated version of the project requires a Peggy 2 board (with all 625 LEDs installed), an Arduino (for Serial to I2C data conversion), and a computer running Processing with a video source.
I’m thinking this is probably the absolute coolest Peggy mod possible! If you have an unused/older machine + webcam available, this setup could make for a prime digital art display. Just make sure you build a Peggy 2, and not a first gen Peggy (d’oh!!!)
