Digital Clocks

THE HISTORY
The Nixie tube made its debut in 1954 by Burroughs Corporation and quickly found its way as a digital display in
high end test equipment, frequency counters, military applications and research projects. Soon they
were used as the very first electronic digital display in consumer products like calculators,
and the very first digital clocks. For those that were there, who couldn't forget that warm
golden glow of actual formed numbers one through zero changing before your eyes!
The tubes were and still are a marvel in themselves! While resembling a standard vacuum
tube, they had ten separate cold cathodes precisely formed into the shape of the ten numer-
ical digits, stacked one on top another! Filled with neon gas, each digit would emit a charac-
teristic and appealing soft orange glow when 170 VDC was applied between its respective
cathode and its wire mesh anode. Even though they were tubes, their cold cathode design did
not generate the heat normally associated with standard heated cathode tubes. The name "Nixie"
was derived by Burroughs from "NIX I", an abbreviation of "Numeric Indicator eXperimental No. 1". Hundreds of Nixie tubes with size and display variations were manufactured dur-
ing their lifespan.
In 1970, the RCA introduced the Numitron tube with incandescent filaments arranged into a new seven segment styled display that emulated the numbers one through zero with var-
ious combinations of the seven illuminated incandescent filaments. While not perfectly rounded and formed digits, the straight segments of the Numitron seven segment display
became the standard for all future numerical displays including the vacuum fluorescent display (VFD), LED, and LCD seven segment displays.
In the early 70's the Nixie tube was replaced by these newer technologies because they did not require the complex cathode structure, provided higher resolution graphics, were
smaller and less fragile, and did not require high voltage to drive them. LED displays quickly became the standard display for all digital display products. Subminiature versions even
found their way into the early Pulsar wristwatches
(although Steve Wozniak did have a Nixie wristwatch)!
Ironically, Ramsey Electronics® started up in the early 70's and one of our first products was a neat and very high tech 7 segment LED clock kit in a nice extruded aluminum housing.
It became extremely popular and we became famous for bringing state-of-the-art IC driven LED display technology to the hobbyist! Now, more than four decades later, we are proud
to bring not only a piece of history, but a piece of Ramsey history back to the hobbyist... The Nixie Tube Digital Clocks!
RETRO WITH A TWIST!
Designed to pay homage to the era which birthed the Nixie, these clocks won't pick up radio stations, won't dock your iPod, and certainly won't play CDs. But what they will do is
display the time, beautifully and simply, like no other clock today can! Once utilized for military and high-end test equipment, Nixies are now prized for their modern aesthetics. The
warm neon glow of a Nixie clock adds a cool retro touch to any office, home or work area. But hidden beneath those beautiful tubes from the 50's is some of the latest technology
providing you some of the neatest features available in a clock today. You truly have the best of both worlds… or both eras!
YOUR CHOICE OF APPEARANCE!
We can take you back in time to the 60's and 70's with that unforgettable classic warm glow of Nixie tubes but the trip wouldn't be complete without your
choice of a custom matching base. Back in the late 60's remember when radios, TVs, and other devices were all supplied in furniture quality wood cabi-
nets? From the old floor model AM radio to the latest console TV, there was no veneer or composite materials to be found! Keeping with that era you
can choose a solid two tone teak and maple clock base for your clock! Made out of fine hardwoods, these are hand crafted and hand rubbed to a furni-
ture quality satin finish. The teak maple base has become our signature base for our Nixie clocks. IN-14 tubes shown with upside down “2” as the “5”!
Continuing the look-back in time, in the early 70's shiny metal and chrome became the "in-thing". From metal radio and TV cabinets with shiny bright
trim to vinyl covered furniture with plated steel legs, to the chrome blender and toaster in your kitchen. If that is your "look", the custom polished alu-
minum base is for you! This base is crafted from one piece of solid aluminum, milled to precision and polished to a mirror finish. The warm glow of the
Nixie tubes along with the LED mood lighting will nicely reflect across the surface of the clock. IN-8-2 tubes shown.
Finally, if you really want to mix the authentic "golden age" with futuristic technology, and are proud to display it, then our clear see-through acrylic base is for
you! Not only will you see the Nixie tube display but you, your friends, and family will see the inner workings of the clock! If you’ve ever owned an
Accutron Spaceview watch, you will remember how neat it was seeing the tuning forks and little miniature parts inside. With the see-through base you
will see everything from the microprocessor to the LED indicators. Plus, the glow from the color LED mood lighting will reflect throughout the case creat-
ing a great display as well as an incredible conversation starter! Whether it be the fine hardwoods of teak and maple or the futuristic see-through
base, your clock will be a proud addition to your home or office. IN-8-2 tubes shown.
YOUR CHOICE OF TUBES!
Since their "demise", Nixie tubes haven't been manufactured domestically for decades. However they were still being manufactured in high volume in the mid 80's in the former
Soviet Union at the Reflector factory in Saratov City. While no longer manufactured, it is still possible to find them as "new old stock" (NOS) from Russian parts warehouses if you are
“in the know”! We give you the choice of two very different Nixie tubes for your clock… read on!

Classic Nixie Tube Clocks
K I T
Wired & Tested
IN-14 Nixie Tubes
New old stock tubes, with a digit height of .7", an overall tube diameter of .75", and an overall tube height of 2". These tubes provide the classic soft glow of the
original Nixie tube. However, the cold cathode for the digit "5" is in reality an upside down "2" cathode. These space-race era Russian manufactured tubes reflect
an efficient and cost effective design philosophy from the cold war superpower! Both unexpected, effective, and thought provoking! And a neat conversation starter!
IN-8-2 Nixie Tube
New old stock tubes, with a digit height of .7", an overall tube diameter of .75", and an overall tube height of 2". These tubes provide the classic soft glow of the
original Nixie tube. Identical to the IN-14 tube in size and display quality, however the digit "5" is a true digit "5" just like the original domestic Nixie tubes. You lose
the provocative conversation starter of the upside down "2" but you get an authentic "5" in its place!
