Web Interface Controls Nixie Tube Clock

We love our clocks around here and we love nixie tubes as well. The combination of the two almost seems to be a no-brainer. With the modern twist of an ESP8266, Reddit user [vladco] built a minimalist nixie tube clock.

The build starts with the nixie tubes, Russian In4s, each one mounted on its own small circuit board. Each board is chained together and they’re mounted on a wooden frame. The frame is mounted inside a nice wooden case which was designed in Fusion 360 and milled out of oak at a local hackerspace.

There are no controls on the case. No buttons or knobs. This clock is set via the EPS8266 which gets the time and updates the shift registers that set the numbers on each of the tubes. The clock dims at night so it’s not as bright. [vladco] wrote a web UI to set the time and interact with the  tubes.

The code and files for the case and circuit board are available online. The result is a nice, minimalist clock for your desk. There are plenty of clock builds on the site, several built from nixie tubes, including another nixie tube clock with an ESP8266, and another.

Exquisitely Crafted Nixie Tube Weatherclock

The Weatherclock is more than just a clock sporting Nixie tubes and neon lamps. There is even more to it than the wonderful workmanship and the big, beautiful pictures in the build log. [Bradley]’s Weatherclock is not only internet-connected, it automatically looks up local weather and sets the backlights of the numbers to reflect current weather conditions. For example, green for roughly room temperature, blue for cold, red for warm, flashing blue for rain, flashing white for lightning, scrolling white for fog and ice, and so on.

While seating the sockets, [Bradley] noticed that an Adafruit Neopixel RGB LED breakout board fit perfectly between the tube leads. By seating one Neopixel behind each Nixie indicator, each number could have a programmable backlight that just happened to look fabulous.

[Bradley] says his family had gotten so used to having the Weatherclock show them the outside conditions that they really missed it when it was down for maintenance or work – which shouldn’t happen much anymore as the project is pretty much complete.

It’s interesting to see new features in Nixie clocks. Nixie tubes have such enduring appeal that using them alone has its own charm, and at least one dedicated craftsman actually makes new ones from scratch.
