In my case, I used the DS3231 RTC and a arduino-compatible WiFi-breakout called "Wemos D1 R2". This way I could use the code from my previous post (Set RTC via WiFi) and simply add the nixie-library in order to control the tubes/show the date. For this setup I made a small single-sided pcb for the Wemos in fritzing:

Because the code for this project is too long for this post, here's only an excerpt. You can download the complete arduino-program here. If you are interested in the fritzing-file, leave a comment down below.
