Frequently Asked Questions

Q: Do the IN14 Nixie tubes come included with this kit?

A: No — this listing is for the PCBA circuit board kit only. The IN14 Nixie tubes are NOT included and must be purchased separately. The board is designed to accept standard IN14 Nixie tubes, which you solder onto the white PCB pin pads.

Q: Do I need programming skills to assemble this Nixie tube clock kit?

A: No programming is required. The STM8S005 microcontroller comes with built-in firmware already loaded. Once you solder your Nixie tubes and power tubes onto the board and connect a Micro-USB 5V 1A power source, the clock is ready to use. Basic soldering skills are recommended for assembly.

Q: What backlight colors are available on this DIY Nixie clock?

A: The clock features an RGB LED backlight system supporting 7 different colors. You can manually cycle through colors using the Down button, or activate auto-color-change mode, which automatically switches to a new color each day for a dynamic, ever-changing display.

Q: How accurate is the timekeeping on this Nixie tube clock kit?

A: This kit uses a high-precision imported clock chip that keeps exceptional time — with less than 1 minute of drift per year. This makes it highly reliable for everyday use as a display timepiece.

Q: What is the anti-poisoning feature and why does it matter?

A: Nixie tube "poisoning" occurs when certain digits are displayed infrequently, causing those cathode elements to degrade faster. The anti-poisoning routine cycles through all digits at regular intervals (every 1–9 minutes, user-adjustable) to promote even wear and extend the lifespan of your Nixie tubes.
