If you consider building a nixie clock without using pre-designed PCBs, these website might prove helpful :
- Mike Harrison, Build a Nixie-tube clock — Lots of informations about nixie clock circuits. In particular, you may want check the schematics of his clock and his power supply circuit.
- M. Moorrees, Nixie Stuff — Another high-quality information source about nixie clock circuits.
And if you do want to use Arduino to run your clock, here are some option you might want to look at :
- ArduiNIX, ArduiNIX shield for Arduino Uno — The ArduiNIX shield is a user open-source programmable platform for driving multiplexed nixie tubes or other high voltage displays (used on this clock).
- RLB Designs, PCB nixie clock — This compact standalone clock is powered by an Arduino Nano and has five built-in inputs as well as a RTC in its latest version.
Some links about nixie tubes themselves :
- ExplainThatStuff, How nixie tubes work — In depth explanations on nixie physics and operation.
- Wikipedia, Nixie tube — A rather complete article.
- Tube-Tester, Nixie World — Huge nixie tube inventory.
- Evil Mad Scientist, Nixie tube take-appart — The dissection of a nixie tube is performed, with neat pictures.

If you want to stay on Hazardous Physics, I would suggest you read :
- RLB Designs' nixie tube clock — Electronic schematic and source code for RLB Designs' standalone PCB clock. This clock shares many similarities with it regarding electronics and programming.
- Nixie tube at 300 000 V — A little fun with nixies tubes and a Tesla coil. It produced very beautiful displays, which also highlight how a nixie tube works in normal conditions.
