WWVB clock progress [01315859368]
Chris was kind enough to pass along to me a commercial WWVB receiver. This module was a bit of a pain to develop for, because most of the time the interference from a nearby laptop computer is enough to seriously compromise reception, and almost all of the time having a USB cable running from the microcontroller to the laptop will kill reception outright.

Towards my GPS LED Light Clock [01308773950]
A few years ago, I made a CCFL light clock using an Arduino with a custom shield containing a transformer (to get a reliable 60Hz timebase) and a triac (for solid-state switching of the lamp). By having a simple 7-day alarm calendar (set at compile time), the clock seldom requires interaction except for the reading lamp function. However, the design has two main problems:
