Frequently Asked Questions

Q: Does this IN-18 Nixie Tube Clock base come with the nixie tubes?

A: No, the IN-18 (VH-18) Nixie tubes are not included with this motherboard base. You will need to source them separately. The base is designed specifically for IN-18 tubes with thick pins, which plug directly into the onboard sockets without any soldering.

Q: What power supply do I need for this Nixie Tube Clock motherboard?

A: The clock base requires a 5V DC, 2A (or higher) USB-C power source. It is compatible with standard phone chargers, USB power banks, and computer USB ports. If you experience display issues, switching to a higher-quality 5V/2A power supply is recommended.

Q: Can I customize the LED lighting on this nixie tube clock base?

A: Yes! The advanced RGB LED underglow supports multiple modes: you can turn the LEDs off completely, set them to a fixed color of your choice, or enable automatic gradient cycling for a dynamic ambient glow effect.

Q: What is the cathode poisoning prevention feature on this clock?

A: Cathode poisoning prevention (also called anti-poisoning or slot machine mode) is a built-in program that periodically cycles all digits in each nixie tube at adjustable intervals. This prevents uneven wear on the tube's cathodes, extending the life of your IN-18 tubes significantly.
