Digital Wall Clock

12ft GPS Wall Clock

It's the project that just kept getting larger. We combine some LED light bars with a simple controller and a GPS receiver.

About 6 months ago, we discussed creating a 6' tall alarm clock - authentic down to the Timex face plate. While this may sound like a silly idea to begin with, it quickly became obvious just how difficult it would be to build at that scale so the project was scuttled. Recently, I came across a source for pre-package LED light bars that rejuvenated my need for a big clock. Why not?

I now hate Styrofoam. If you want to replicate any part of this project, prepare to have little white balls all over your work area.

So here is the little project that grew to 12 feet. We added a GPS receiver so now we have a 12' clock that sets itself, displays hours/minutes/seconds, and is accurate to 100ns. Beat that bed side alarm!
