Today we soldered up Nixie tube thing blocks. We wrote a small sketch for the Arduino to turn on/off each filament on the Nixie board in a loop. It works great. We also played around with a VFD tube (pictured above), trying to get it to light up.
We fixed the dimension on the IN-12 Nixie tube footprint, based on actual measurement. Continued to tweak the ATX Breakout Board v2 in KiCad, this time moving some outputs around, and fixing up silk issues. We made our silk logo in KiCad.
