Nixie compact, thermometer, clock GPS, letter box alarm:
This is the story of a Christmas gift for my father...He always like old things and nixies must be good for him. Like many people, I like this display, warm color.The original idea was to create only a thermometer, internal and external. For external, I wanted to have solar recharge, RF transmission. For internal, a traditional DS1820 to get the temperature.
