Main PCB of my Nixie clock

Board overview

  • 12V AC input
  • Rectified, smoothed 12V AC output (around 16V DC, powering the 180V power supply)
  • ATmega32 AVR microcontroller as the heart of the Nixie clock
  • Photoresistor input for PWM Nixie tubes dimming
  • Two inputs for external buttons used for timezone setting (UTC offset): TIMEZONE- and TIMEZONE+
  • GPS module connector (3.3V, ground and GPS_TX line) with power on/off capability
  • 6P6C connector used for interfacing the Nixie clock tubes driver board
  • AVR ISP connector for AVR programming
