After completing Nixie Clock 1 over a year ago, I still had an extra set of IN-12B tubes that were not being put to good use. Time to build another one. Actually, I ordered yet more tubes and driver ICs so I could build 3 more.
The basic design is almost the same as Clock 1: Russian IN-12B with a K155D1 driver for each tube, shift registers to run the drivers, and this 180V power supply design Remembering some lessons learned when I built clock #1, I made the following list of improvements:
- Simpler (or no) sockets. Most of the time towards building the first clock was wiring the 72 pins on the tube sockets. If I could somehow avoid doing that, it would save me lots of time.
- PCB for components. After designing some PCBs for some of my other projects, I realized that it really isn't that hard. Having a PCB should make everything smaller and neater, and cut down on assembly time.
