A new clock design, featuring a blend of retro technology and modern craftsmanship, has emerged from the creative mind of inventor Changliang Li. This innovative timepiece utilizes homemade Nixie tubes alongside vintage Soviet-era cold-cathode tubes to deliver a strikingly unique aesthetic.
The clock prominently displays time using Nixie tubes, which are known for their vibrant neon glow. However, the standout feature is the integration of MTX-90 cold-cathode thyratrons as logic components. These tubes resemble neon lights in operation, as they utilize similar principles while incorporating an extra trigger electrode, although this specific circuit does not employ that feature.
The internal mechanism of this clock includes a loop counter created from the neon tubes, converting the standard 50 Hz mains electricity into a functional time display of seconds, minutes, and hours. This design is not entirely original; it draws on established circuitry principles found in older electronics literature and is attributed to PA3FWM.
Craftsmanship and Functionality
The Nixie tubes used in this project are manufactured by Sadudu at iNixie Labs. A video detailing the production process reveals that a fiber laser is utilized to cut the glowing elements, which are then assembled using machinery resembling a lathe.
The cold-cathode tubes employed as logic components rely on ambient light or background radiation for reliable operation, as the trigger electrode remains unconnected. To enhance the switching reliability of the thyratrons, Changliang Li incorporates a surplus smoke detector source. This addition ensures adequate ionization for optimal performance. There are claims that the MTX-90 tubes were initially embedded with radioisotopes, although there is no verified evidence to support this assertion.
The final product is not only functional but also visually captivating. Observers describe the clock as attractive and somewhat hypnotic, with its glowing tubes creating a mesmerizing effect. For those interested in exploring similar applications of neon technology and Soviet MTX-90 tubes, a more in-depth analysis was previously shared in another article.
This inventive project exemplifies how traditional and modern technologies can converge to create something extraordinary. If you have a project inspired by similar innovative ideas, sharing it could inspire others to explore their creativity.
