Nixie Tube Alarm Clock: It’s Alive!


A lot has changed since my last Nixie Clock post in 2010. Using Eagle I had a prototype board made through 4PCB, unaware of their Student $33 Each deal; If you are a student use this! After soldering in all the components and testing the circuit it turned out that multiplexing was not a good decision. I was unable to switch at a high enough frequency while maximizing ignition of the tubes. In other words, I would either see the numbers scrolling in a bright neon light or I would see all at once in a dim neon light. Unfortunately there was no software fix. Discouraged and busy the project was dead until about 6 months ago.
