Ta-da! The two clocks are based around most of the same stuff, except I used a 1.04 version of the Nixieclock driver board. The technical reason has to do with how the power supply works between the two version. Nothing wrong with the newer version, just needed (I felt) more amps for the larger tubes. Fun fact about this clock, since I needed to wire up the P/S, I used and old joystick cable from an Atari 5200 for that. :)
To give you an idea of how much larger this clock is compared to the proto-type:
The glowing fading numbers look better than I could have hoped for.
BTW, the other different between the two clocks is the tube source. I picked up these 6 IN-18 tubes from E-Bay. So that was a big price saver.
Only one more Nixie clock to go. But I have to finish up the Binary clock first. It's got to go cross-country here real quick.
