DotKlok - An Open Source Arduino Base Dot Matrix Clock

Dot Matrices are small blocks of grouped together LEDs (Light Emitting Diodes) that usually used for display purposes that a single LED would just not suffice - like? A bunch of numbers, letters, pacman figures, ect.


This project from Andrew O'malley (Im guessing he has Irish roots coz of the O) makes use of a bunch of LED matrices to artistically display time (check out his site for more pictures). Its built on the arduino platform (which makes it more attractive - friendly even for beginers) and its open source!

It features 14 user-selectable time animations, 24/12 hour modes, "random mode" can switch animations each day at midnight, 3.75" x 2.5" / 10cm x 6.5cm LED display, 5 adjustable brightness levels, dedicated DS1307based real-time clock (RTC) chip keeps date/time with backup battery, 4 button time/display interface - and I did say its built on the arduino platform right (?) then its easily reprogrammable to suite your needs.
