Over a year ago I created the video about nixie tubes. It explained how nixie tube works, how you can power it.

This video did not however explain how you ca control this tube from within Arduino code.

So here is a video which will show you how to control a nixie tube with arduino and dedicated K155ID1 microchip.Hope you like it:)

EXPANDED TECHNICAL DETAILS

Retro-Tech High Voltage Interfacing

Nixie tubes are vintage cold-cathode neon lamps that require high DC voltages (170V+) to illuminate, necessitating specialized driving circuitry.

  • K155ID1 Driver: This specialized Soviet-era BCD-to-Decimal decoder chip is designed specifically for Nixie tubes. It takes a 4-bit binary-coded decimal (BCD) input from the Arduino and sinks current from the corresponding cathode (0-9) inside the tube.
  • High-Voltage Boost Converter: The Arduino manages a specialized Nixie Power Shield that boosts 5V or 12V DC input up to the 170-180V required for the tubes.

Precision Timing

  • Multiplexing Logic: To conserve pins and power, multiple tubes are often "Multiplexed." The Arduino rapidly switches between digits at 100Hz+, faster than the human eye can perceive, creating the illusion of a solid, multi-digit display while using only one driver chip.
