Binary Nixie Clock with 21 x IN-12 & IN15 Nixie Tubes for Arduino Classic Uno / Nano / Nano IoT 33 / Nano Every etc.
Build a clock, counter, thermometer or any display with 2/4/6/8/10 nixie tubes. You can use your favorite platform for this: Arduino, Raspberry Pi, Particle etc. Are you interested? Imagine that you can use any nixie tube and not worry about the technical parameters: power requirements, current, and what is most troublesome and what you also do not have to worry about are different types of tubes with different pin layout is not a problem either. The device has been designed to make work with nixie tubes as easy as possible.
