If you really want to spice up a New Year's Eve party, you don't want to rely on some boring old TV announcer or phone to tell you the time. Over on Soldering Station, they show you how to build your own countdown clock.
In order to build this, you'll need an Arduino, a switch, a display, some housing and a few other parts. The whole thing's then packed inside a cereal box assembly, soldered together and queued up for the countdown. Is it overkill? Most certainly, but it's fun nonetheless.
