AXIRIS IV-3 Shield for Arduino is super great project, specially power supply is very good designed. etc. filament is driven with AC voltage which is recommended for VFD. 12V input voltage is 3x multipled to make 36V I am redesigned board for easier soldering, all components are in lines with same value

  • added buttons for HOUR / MINUTES
  • speaker driver for make alarm clock, in current firmware is only hour beep implemented
  • components values on PCB
  • DS3231 with battery backup
  • Enhanced to 6 DIGIT
  • hand painted curved traces for more retro look
  • all outputs are marked on pcb for better debugging
  • schematic is almost unchanged, some pins are swapped for better PCB routing

I created simple CLOCK arduino sketch (firmware)

Little updated new layout.
