Canning and Preserving Class
Crossing Over vs. Crossing Under
I'm not too sure, but I've read that they can run for decades. I've tried to ensure that they last as long as possible in this design by putting the minimum amount of current through that will light up all the digits completely. My clock has been running for about 10 months and the digits haven't dimmed at all.
Thanks, and good luck with your build!The Nixie Visualizer does look pretty cool. Maybe one day I'll make something similar.
