Our goal is to make products that last. Therefore we provide 10 years warranty for our clocks and nixie tubes. Learn more about the warranty.


How it works

The Blub is a single-tube nixie clock - all digits of the time are rotated one by one on a single nixie tube. It sounds complicated, but it works surprisingly well. The time is kept internally by high accuracy real-time-clock chip.


The clock's heart

The clock's heart is an Atmega328p microprocessor paired with a DS3231 high accuracy real-time clock for time-keeping. This setup makes the clock fully standalone without the need for external time synchronization.


Configuration via push buttons

Two push buttons create the user interface on the back of the clock. Besides the buttons, the Blub clock contains a mini USB connector used to connect to a power supply and offers advanced configuration options over a serial line.

Black anodized surface finish

Anodized aluminum case

The clock case is milled of a solid aluminum block, sandblasted with fine glass beads, and finally anodized. We use the same material finishes for our Puri clocks. It looks fantastic and resistant to scratches.


Before we ship it to you..

For the Blub clock, we've stepped up the final quality inspection procedure - we developed a semi-automated testing fixture. The development of this new tool was probably more complicated than the development of the clock itself - but in the long term, it will pay off in the reliability of the electronics passing the test procedure. It allows us to test all necessary electrical parameters as well as software functions and features. All this helps us to achieve higher consistency in the quality of the product we deliver to our customers.


Materials and finishes

The Blub clock can be purchased in several colors and materials. The clock body is always anodized aluminum - the color options are silver and black. The nixie tube base can be made of anodized aluminum, polished stainless steel, or polished stainless steel with a golden look. All the materials used are stable over time and don't tarnish.

Black (black anodized clock body + black anodized tube base)
Silver (silver anodized clock body + silver anodized tube base)
Black/Stainless (black anodized clock body + polished stainless steel tube base)
Black/gold (black anodized clock body + polished stainless steel tube base with golden coating)
Silver/Stainless (silver anodized clock body + polished stainless steel tube base)


Getting them safe to you..

Having a batch of functional and tested clocks for sale is one part of the story - getting them to customers is a whole other thing. Our packaging uses a metal can with custom-made foam inserts. Reliable and good-looking. Just use a screwdriver to open it!

What is the expected lifespan?

Single tube nixie clocks are special in one aspect - the character of nixie tube operation is very close to the optimal operation - individual digits are cycled regularly. There are no situations when the nixie tube shows only one digit for prolonged periods (e.g., as the first tube in a 6-digit clock). This feature allows the nixie tube to avoid cathode poisoning and achieve maximal theoretical lifespan - which should be, according to our calculations, more than 15-20 years.
