DIY Arduino Watch

Arduino is known to be an easy-to-use prototyping platform where physical computing is concerned, as it helps simplify the entire process of programming micro-controller chips and sensors. Franklin Chang has decided to use the Arduino mini pro to create his digital wrist watch, using parts from a discarded Nokia 3310 phone (the LCD display), where one will see the current time. Powered by a rechargeable lithium coin cell battery, the whole watch looks just too cool.
