Nice. I've been starting to think about adding a nixie tube clock to my steampunk camera (see my icon photo). I've been starting to search around for guides and such. I would be interested to see your wiring diagram, etc. Note, for the camera, one big concern is it has to be portable, so I have to do it with batteries.
Thanks for the feedback. The wiring diagram for my clock is quite similar to this one
(with some minor changes). The schematics for the shield itself are here
. There are code samples provided on the Arduinix website, which implement the truth table of the drivers (plus the time count). You can use this to have the nixies display whatever you want. The whole thing feeds on 9V, 660mA.
Hope this helps !
