Bluenumi began with the idea of creating an easy to assemble open-source kit clock that had nixie tube aesthetics, but without the associated cost orpotentially dangerous high voltage. The result is a small, functional, and beautiful desktop clock featuring 100% through-hole electronic components that looks like a nixie clock, but can be built at a fraction of the price.
