Czech artist Dalibor Farný created a documentary that outlines his process for the beautiful and complicated art of handcrafting Nixie tubes, cold cathode displays that were commonly used before LEDs.
The nixie tube is a vintage display device which had been used until 70s when it was replaced with LED displays. The complex knowledge of manufacture of nixie tubes literally died with tube factory’s engineers, glassblowers and machine operators.
I discovered nixie tubes in 2011 and since then, I’ve devoted all my time to studies of nixie tubes and its manufacturing processes. After years of intensive work, with help of many people, I eventually succeeded and have revived the knowledge and equipment for production of nixie tubes.
