Adafruit Ice Tube Clock kit

Bask in the glow of nostalgia with a clock kit crafted around a retro Russian display tube, exuding a cool blue luminescence. Designed with precision and adaptability in mind, it features an 8-digit display, PM dot, and a convenient alarm on/off indicator.

With adjustable brightness and an alarm equipped with volume control, your day will start just right. The precision watch crystal maintains accurate timekeeping with an error margin of less than 20ppm, equating to a deviation of under 2 seconds daily.

A clear acrylic enclosure offers protection, blending function and style seamlessly. Rest assured, its battery backup keeps time intact for up to two weeks without power interruption, accompanied by a selectable 12h or 24h display mode and the option to display the day and date at the press of a button.

Convenient for desks or night tables, this compact timepiece measures a neat 4.9" x 2.9" x 1.3" (12.5cm x 7.4cm x 3.3cm). Thanks to its integrated boost converter, it operates effortlessly with standard DC wall adapters, suitable for any global mains power.

An ideal playground for innovation, the completely open source hardware and software invites customization and enhancements by tech enthusiasts. The comprehensive kit includes all necessary components: a vacuum fluorescent tube, backup battery, and the elegant acrylic enclosure, along with a 110/220V 9VDC power supply. Assembly guides and more resources are just a click away on the Ice Tube Clock webpage.

Please note that due to the popularity of this unique kit and diminishing tube supplies, prices may increase gradually until availability runs out.
