μWWVB: A Tiny WWVB Station
Hi HN! I wanted to share the story of µWWVB, a watch stand that I built that automatically sets the time on my atomic wristwatch.Because I can't receive the regular atomic watch radio signal where I live, I built a device that determines the current time by using GPS and then emulates the WWVB protocol to set my atomic watch.In the process of building this, I learned a lot about time, clocks, radio, and WWVB, and so I thought I'd share what I had learned.
