Hi Eric,
You should take the time to draw up a schematic and post your code to
the files section. I'm sure that lots of members, both current and
future, would appreciate the work you have done. To the best of my
knowledge, nobody has posted any arduino nixie clock code here yet, so
this would be a great addition.

Hi my name is eric and I am 17, I started of will no experience and I have
built a clock using a Arduino clone called anarduino, It's a very small module
type package. Having no previous programing skills I have completed my nixie
clock. My arduino gets the time from a Real Time Clock 1307, from there it
shifts the data out to a shift register 74hc595... a shift register will turn 3
pins from the microcontroler into 8 more pins, the first 4 pins go to the HV
driver 74141 the other 4 bits go to anode driving transistors to turn each
nixie on and off. I would be glad to share my code and I could make a diagram.
So my clock has 4 bulbs (IN-12) and it turns on one at a time and displays that
number, then it turn off and the next bulb turn on with the next number, when
you do this fast enough that's called multiplexing and you can't tell that they
are not all on at the same time..
So all you need with my desgine is $10 Anarduino $2-3, RTC 1307 $2 HV driver
74141, 74hc595 $.50, some transistors $3 and that it.
Arduino has free easy to get to software and when it gets down to it, it's just a
clock and you don't need a<$20 microcontroler You can email if you chose my
path and I can give you my code
