Nixie tubes were mainly used as digital displays in electronic devices, such as calculators, clocks, and measurement instruments, from the 1950s to the late 1970s. They were also utilized in early computers as memory or storage devices in the form of decoders, shift registers, and counters. Nixie tubes were popular because they were reliable and easy to read, and their glowing orange or green numerals gave a striking visual appeal. However, they were eventually replaced by more practical and cost-effective LED and LCD displays. Today, Nixie tubes are mainly collected and used for decorative and artistic purposes.
The clock can be configured to just show the time or the time intermittent with the date. Also a black-out period can be set during 01:00 - 06:00 to spare your Nixie tubes.
On first use, your clock needs to connect to your WiFi router to synchronize its time with the internet network time protocol. Once a day the clock will reconnect to re-synchronize. The clock can be used all over the world, standard timezone is set to Amsterdam timezone with support for daylight saving time. During setup, the timezone can be set to another timezone when needed.
