T-Nixie Tube is an ESP32 based Nixie Tube lookalike

I tend to see Nixie Tube projects regularly as I spend my days going through the news, and the projects, usually some sort of clock, typically look pretty neat.

But although Nixie Tubes can still be purchased online, they are not mass-produced anymore, which may explain why LilyGo decided to create a “fake” Nixie Tube, or let’s call it a lookalike, with T-Nixie Tube that comes with an IPS LCD display driven by an ESP32 WiFi & Bluetooth WiSoC.
