@ instructables.com shows us how to build an Arduino Nano based Nixie clock that features DS1307 RTC clock and 4x IN-14 Nixie tubes. He writes:
In this project I will show you how to create a retro nixie clock. That means I will show you how you can control nixie tubes with a high voltage DC power supply and then I will combine 4 nixie tubes with an Arduino, a Real Time Clock (RTC) and a custom 3D printed enclosure in order to create the nixie clock. Let’s get started!
