Vacuum tubes scream Steampunk and old diodes. If you think that the 1500-LED digital clock is too fancy for you, maybe you should go for something older and more vintage. Recently, a dot-matrix numbered clock was featured for sale on ebay. We initially thought it was an LED clock, but in actuality, it's a Elektronika-7 clock was built using vacuum tubes. Now how cool is that?
The Elektronika-7 (Электроника-7) is a rare Russian relic from the early 80s and it uses vacuum tubes to show the time in its unique blue-green display. The almost industrial strength clock uses 16 segmented tubular vacuum fluorescent displays (VFDs) to form its digits. We found it really surprising that this clock is so old since it looks good. A modern version might be made using Nixie tubes, but it might not look as vintage. [via Technabob]
If you think that old Russian clocks aren't your style, then maybe the Chronotrix IN-18 Nixie Clock might be up your alley. This beautiful looking clock uses vintage Nixie Tubes to display time. These types of tubes went out of production in the 70s when LED display started appearing. It's an incredible looking clock that will attract the eye, no matter where it is placed.
