HOW TO – Make a 21 foot GPS wall clock

Spark Fun Electronics writes – “Why? Well, why not? We had the new LED Light Bars burning a hole in our pocket, so we decided to build a clock. Not just any clock – but a very large 24″ tall, 12 foot wide, clock with GPS current time and accuracy down to 100ns. The clock turned into a huge undertaking. But at least we get to annoy Eric as the huge thing ticks over above his desk…” – Link.

This clock will be at the Maker Faire! Wooo! – Link.
