The Steampunk – Atompunk Nixie Tube Clock is a high quality fantastical time piece. The clock is controlled by 4 buttons, located on the rear of the unit. A nixie tube is a cold-cathode low-pressure vacuum tube that lights a series of digit filaments surrounded by neon gas. A small electrical current is then passed through the tube, lighting the digit filament. The clock can be easily programmed for time as well as the date. Date can be programmed to scroll across the clock every minute. Also, you can choose from a wide variety of woods for your Steampunk – Atompunk Nixie Tube Clock.
