Here is my nixie clock :
6x IN14 russian tubes
6x Neopixels Leds
2x HV5530 high Voltage drivers
1x 210V High Voltage step up power supply
1x 5V step down power supply
1x ESP32 microcontroller
1x radar sensor
1x light sensor
1x (option) temperature + pression sensor
2x home made pcbs
And one Android application speaking to the ESP32 with Bluetooth Low Energy
Just add a piece of wood (from Vietnam :)) a CNC mill, a 3D printer (for spacers and leds' light under the tubes), one lathe (for aluminium rings) and a lot of hours.
