Unfortunately, i'm still at the breadboard stage, so no soldering yet. I forgot a lot about nixies, and programming, so I'm taking baby steps.
Keep these suggestions coming, eventually we'll figure it out. Shane On Wed, Jul 20, 2011 at 8:40 AM, jb-electronics <[email protected] > wrote: > ** > Maybe some bad soldering?
