I’m in the very early stages of prototyping a nixie clock. I picked up some MJE340 power transistors to switch on some IN-3s. I can then use a digital pin on my Arduino to turn on the IN-3s through the transistor. I’ll then have myself a blinking colon for my nixie tube clock.
Check out the video after the break.

Yay cool :o)
I built a nixie clock with a PIC a while back. I pinched the last “digit” from the BCD signal it runs on, fed the bit into a monostable to get a steady on/off cycle…
