The team at Spark Fun Electronics, a student-run business, decided that a 6-foot wide LED alarm clock wasn't big enough. Instead, their little project grew to a 12-foot wide alarm clock with LED light bars, a simple controller, and a GPS receiver that sets the time all by itself.

To build the 12-foot time masterpiece, they used everyday tools, such as a handsaw, glue gun, sharpie, and box cutter. To get that glowing look, they used 8 LED light bars running on 12 volts to create the 6 digits and 2 colons. Just how accurate is it? Down to 100 nanoseconds.

It gets a bit more technical than this, so if you're interested in building a 12-foot LED Light of your own, they show you how. In the end, it took Spark Fun Electronics two weeks to cut the digits, three hours for the hardware layout, and an hour for the firmware.

The GearLog verdict: If you work for or own a business that's always on crunch time, then having a huge a** clock will make your deadline that much more in your face.
