I love robots. They have the potential to evolve into Asimovian destroyers of the human species, but have only just mastered the art of cleaning my rug. They have an ever increasing cool factor and a growing number of cheap and simple components that let the hobby roboticist reach for the burning miasmas of plasma. But to get to the stars, we need to start with the basics.

The cell phone has come a long way. The very first "mobile devices" were made and used by the military in the late 1930s, with the first commercial mobile telephone service introduced by Bell in 1946.

Frank Zhao, an electrical engineering student at the University of Waterloo, decided to do something a little different with his LED pocket watch. It h...
