Fresh hacks every day
[Josh] and his lab partner [Eric] needed a final project for their Embedded Systems Design class, and thought that designing an Arduino shield would be a cool idea. They noticed that there are plenty of ways to get an Arduino to keep time, though none that they knew of utilized WWVB (Atomic Time) signals directly.
[Mark Gibson] sent us a load of details on his build, a WWVB atomic clock using a pinball machine marquee (PDF). This is the upright portion of an old machine that used electromechanical displays instead of digital electronics. It’s big, noisy, and seeing it running might make you a bit giddy. Luckily he included video that shows it working on … Read the rest
[Chris Kuethe] shows how to scavenge what could be a pricey WWVB module from a radio controlled clock. WWVB is a special radio station in Colorado that transmits an atomic-clock-derived signal to RC clocks. The clock model he uses, the Atomix 13131, goes for less than twenty bucks. He also shares the link to another tear down of a … Read the rest
