Desktop NeoPixel Clock

My project is building a simple desk clock with NeoPixel rings and a WeMos (ESP8266) processor, which is also a beautiful piece of a art.

Description

Now that I have learned how to make a PCB, earlier limitations of complicated wiring and my soldering ability have melted away. My second PCB project is an experiment in NeoPixel rings, and also network connectivity. This might be a new take on representing time. I also have a different take on how to synchronize with time.nist.gov. Hardware design, software design, and full source code is presented. The ECAD program Fritzing is discussed. see http://www.whatimade.today/desktop-neopixel-clock/

Details

The details of this project are fully on my blog.

In that blog, I cite similar projects which inspired me; discuss CPU selection, concluding on why I selected the WeMos D1 Mini. Then I go through the hardware design, including a breadboard view, the schematic, and the development process for building the PCB.

I learned several tricks and shortcuts for Fritzing, and I detail those.

Once the boards were in hand, I did a Unit Test.

Then started software design. I discuss in detail how the networked-time function works, because I think it is simpler than any other NTP synchronization code I've seen.

I try to teach a little about the art of embedded programming, and finally present all the source code.
