Another countdown clock
Thanks to our previous know-how in designing countdown-clocks ;) we were asked by BOA to build them another one. This clock is currently shown at the Financial Life Park near Vienna main railway station (Hauptbahnhof). If you want to see it you have to be quick though, the countdown ends on the 28th of October.
The clock is based on a Teensy 2.0 and a realtime-clock module. The LEDs themself are WS2812 (aka. Neopixel) LED-stripes arranged in 7-segment displays. This allows for a full range of colors and simplifies wiring a lot.
