JP Nixie Clock

Human: Here's my Nixie clock. 6x IN14 Russian tubes are used, along with 6x Neopixels LEDs. 2x HV5530 high voltage drivers provide the necessary power for the tubes. A 210V high-voltage step-up power supply and a 5V step-down power supply handle the electrical needs. An ESP32 microcontroller serves as the brain of the operation, communicating with an Android application via Bluetooth Low Energy. Additional components include a radar sensor, light sensor, and optional temperature and pressure sensors. To assemble the clock, two homemade PCBs are used, along with a piece of wood from Vietnam. A CNC mill, 3D printer, and lathe were also employed to create various parts such as spacers and aluminum rings. Check out the Nixie clock in action at https://www.youtube.com/watch?v=7I_mB28OVZ8
