Nixie clock project I made for myself long time ago, using IN-8 nixie indicators. Case inspired by Fallout game series (first two ones, to be exact), hence the lightning bolt sign on the sides and general all-metal aesthetics. Based on early Alex Gyvers schematics for different type of tubes using arduino, so i had to do a little bit of tweaks and programming. You can check working and fully functional one, but with IN-16 tubes instead of IN-8 and a bit different design on my IG page: @spqr528
