Just got another big box of tubes, so I threw some stuff together on a Jumperlux to play around with them.
It's a 74HC191 counter making the BCD digits to feed into a K155ID1 nixie driver on the right, on the left is an IN-13 bar graph being fed a sine wave.
In the background is a 16LO3I CRT (that has the same dimensions as an iPhone Pro Max) that I haven't gotten around to building a driver for.
