In the past few years, we have covered plenty of attractive Nixie clocks here. Thanks to this Nixie Arduino shield, you can build your own Nixie clock, thermometer, and hygrometer. The kit comes with a laser-cut and engraved housing, assembled PCB, 170v Nixie power supply, RTC module, and almost everything you need to get started. It is compatible with Arduino UNO.
This kit is expected to ship in July. You can find out more about it on Indiegogo.
