I just recently bought six IN-14 nixie tubes from e-bay and was immediately faced with the with the thought: "How am I gonna make these work?" Looking up over the internet, I found rather expensive nixie tube clock controllers and custom nixie tube controller boards. The biggest problem with them is the large pin-count and near 175 V needed to power them. After lots of time searching the net for nixie tube circuits I came up with an idea of a cheap modular nixie tube controller system. I even managed to have blue LEDs incorporated into this system. I am really happy how simple the circuitry turned out to be.
Once I get some male and female headers to get this modular and scalable system presentable for a youtube video, I shall post circuit diagrams, protoboard layout and step-by-step tutorial.
Here are some build pics (some of you will figure out the what to do just by looking at the pictures):
