In December, I told you about World's Largest Digital Clock by Citizen, but if you did not liked it due to its hefty price tag then I give you a cheaper option this time which will not just save you on your dear cash but will also give you a feeling of being able to call yourself a perfect geek! SparkFun has an article which tells you to make 12feet GPS Wall Clock all by yourself! The process starts with combining some LED light bars with a simple controller and a GPS receiver that sets itself, displays hours/minutes/seconds, and is accurate to 100ns. So, if you wish to make such geeky-stuff on your own then just go ahead, for now you know how to go about it!!
