I haven't done a project in while and decided I wanted to build another clock. I've always liked the look of Nixie tube clocks and decided to build one. This time I wanted to try using surface mount parts to keep the costs down.
For hardware, this clock uses six IN-14 Nixie tubes for the digits and two IN-3 tubes for the digit separators. An ATmega328 (I'm still not sure if I'm going to use an external crystal or not, but there is room for one on the PCB) is the main controller and a DS3231 RTC is used for time keeping.
