Guys from Evil Mad Scientist Laboratories have released the 2nd version of their Peggy LED display kit. It is a 25×25 LED display board which is capable of displaying various LED effects, output text and even animation with individual LED addressing.
This is quite smart construction allowing to drive any number of LEDs (from one to 625). Peggy board has several buttons that can be used to control various actions like games or other effects. The board itself is nicely designed so it wouldn’t be a shame to use it as a dynamic LED sign, FFT sound graph, RSS reader or simply as general purpose giant display. You can order Peggy board as a kit or try to build it by yourself as all project files are available for creating, hacking or simply analyzing. [Peggy v2.0]
