Here is my latest Nixie clock. I have used a Mr Nixie kit for the clock it's self. However I have created a electronic pendulum. The idea of this clock is for it to hang from a ceiling, maybe in the kitchen.
As I wanted the clock to have the pendulum, be switched of remotley and be time synced, I decided to raspbeery pi control it. This then also ment I could also but sound in the clock, hourly chimes, notification of events. This might seem a little over the top, but being able to turn the clock on/off and save the life of the tubes is very important, i.e. if no one is at home the clock is off.
