Old School Side Project: I wanted to create a universal BCD controlled nixie display driver that could be made into a simple module for any application. Here for demonstration I have breadboarded an automatic counting circuit with a 555 wild clock triggering a BCD output up/down counter to act as a driver for the separate high voltage transistor control/switching board and nixie display, with complete low voltage regulated and high voltage supplies. All vintage parts too. Enjoy!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

hah, i just breadboarded out a similar thing, i used a 555, 74192 and 74141
i’m not sure if you can get 74141s (or equivalent) too easily but there are some on ebay
it may be cheaper than all the transistors and take up less space if you wanted it on a small board
