If you miss the charm of Nixie tube displays checkout this project from Jay Hamlin on Hackaday.io:
The inspiration for this project came from one of Big Clive’s YouTube videos in which he was showing low voltage LED filaments. I bought some 38mm white, 3 Volt filaments on AliExpress and soldered them together as a 7 segment digit on a prototyping board just to see what they would look like. It looked ok but I didn’t know what I would do with it. Later I bought some 20mm red filaments , their color is more red-orange which reminded me of neon. The LED Nixie tube was born!
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
