Foxie Clock

A Nixie-like, retro, RGB LED, Arduino-powered clock

Welcome to the Foxie Clock, a fully open-source RGB clock with nixie-like edge-lit acrylic digits. Or... an RGB pixel display clock, if you like!

Looks

With a look inspired by old nixie tubes and with capacitors protruding through the surface like vacuum tubes, the Foxie Clock is a fun, colorful way to display the time at your desk, office, or anywhere. Brightness, color, and time are all adjustable directly with 4 buttons on the back. Using the clock is very easy, with 4 buttons on the back providing various functionality for setting time, animation modes, colors, and brightness, 12/24h mode, PXL mode, and more.

All .STL models and the full Fusion360 project and the .step files are also available for anyone wanting to make changes to the design more easily. Head over to Thingiverse to download.

Easy to assemble

The clock is easy to assemble and looks beautiful when complete.

Foxie Clock Case Assembled

The case is 3D printed and is included with the kit.

Foxie Clock Case Assembly

The circuit board can be ordered fully soldered, or if you like, you can solder the 4 buttons and RedBoard Nano yourself, using the plentiful pictures in the electronics assembly guide.

Easy to hack

The Foxie Clock is powered by a SparkFun RedBoard Artemis Nano (https://www.sparkfun.com/products/15443), an extremely cool, fully Arduino-compatible board that supports Bluetooth LE 5.0 and much, much more. It is included in every Foxie Clock kit, along with everything you need (including USB-C cable) to get running.

Fully Open Source

The Foxie Clock PCB and firmware were developed using Open Source software. The source code, laser cutting files, PCB design, and documentation for assembly are all freely available here.

Questions

What parts does the Foxie clock nano use?

133 parts, built around the SN74AHCT125N and WS2812B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Foxie clock nano KiCad files?

From the afoxinsocks/foxie-clock repository on GitHub, at the commit this page was made from: the board is board/foxie_clock_nano.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Foxie clock nano design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
