Using Rapid Prototyping To Make A Clock

[Markus] is attending the Royal Institute of Technology in Stockholm. For his Advanced Prototyping class he had to make something using rapid prototyping technology — i.e. 3D printers, laser cutters, and breadboards. He chose to make a fantastic looking clock.

He started by designing the entire thing in CAD. The base is 3D printed on a Ultimaker. The world clock display is a piece of laser engraved acrylic which he heated up and curved to fit. Using an Arduino and a 16×2 LCD matrix he created a simple clock program with the ability to show different time zones. The way you select them is very clever.
