I made this Nixie clock as a gift for my brother. It uses original Nixie tubes manufactured in the USSR in the late 60s. It’s driven by a modern electronic circuit to keep accurate time. The base and top are polished aluminum (cut with a computer controlled waterjet saw by Big Blue Saw), and the center is formed acrylic. It stands about 4 inches to the base of the tubes and is 9 inches wide.
It is currently being featured on the Big Blue Saw web site. Check it out!
