This has been a lotta fun to play around with
For IN-13 Bargraph Nixie Tube With Driver and DC-DC
I bought two of these and had a lot of fun using one of them with a RPi Pico 2 W and a VOC sensor to be an air quality sensor. I used the Micropython driver linked above to prototype with as I got to know how it worked. Then I moved to CircuitPython and added some additional sensors. My slightly modded version of the Micropython driver to get it working with CircuitPython is here: https://github.com/avnc/IN13_VOC/blob/c80b1bda1680e6f182f06a3ab35afc684234b9c4/lib/in13.py ). Unfortunately, I busted one trying to fit it in a slightly too small 3D printed base (ugh), so just ordered a 3rd.
