Numatron Clock

Numatron Clock

LED Nixie Tube - The Numatron Clock.


When we conceived the idea for Retro Electro Designs, we had a desire to produce the very best we could find in terms of unique LED lighting ideas, we have now started producing a range of clocks using upcycled vintage parts.


This clock we have called "The Numatron" - It uses 4 plug in LED 7 segment displays which were called "Numatron Led". These were made as direct replacement for the glass tube Numatron displays which the LED versions superseded. RCA produced the Original Numatron tubes, and these were used in Petrol Pump displays. These LED versions were also used in Petrol pump displays, to replace the less reliable Glass Numatrons, when they failed.


These Led versions are extremely rare, they were only produced for a couple of years, being themselves soon replaced by other display technologies. We saw these a couple of years ago, and have managed to eventually track down a very limited supply of these unique displays.


We have based our clock on a vintage piece of laboratory equipment, A Variable Inductance device manufactured by H W Sullivan Ltd of London. This is beautifully made and a joy to look at. We have utilised the large turning wheel on the front - it now acts as a brightness control to adjust the brightness of the LED displays.


The Clock uses the latest electronics to keep accurate time, and it is also wi-fi enabled. You can easily connect the clock to your wi-fi network and then it will pick up the most accurate time from the Internet.


It will auto adjust between BST/GMT (you can adjust the Time difference, in the settings menu).


As well as displaying the time, this clock can also be set to show a variety of different display animations, it will also 'reveal' the current time in a number of ways. You can choose what is displayed and for how long, and you can setup a list of different displays, which will be shown in turn. Available display options are:

"CYCLE ALL", "Solid Time", "Double Circle Edge", "Blink Medium Time", "Small Circles" "Figure 8s", "Blink Fast Time", "Small Circles 2", "Segment Down Time", "Random", "Slide Right Time", "Clap", "Dropping Time, "Cartwheel", "Segment Up Time", "Circle Edge", "Blink Time", "Circles", "Clap 2", "Appear Time", "Reverse Circle Edge", "Appear Right Time", "Reverse Circles", "Slide Left Time", "Growing Circles", "Growing Time", "Cartwheel 2".

Note: we reserve the right to add, change and remove the patterns. We are constantly developing and improving the patterns.

Simple configuration choices allow you to choose what clock display patterns to show and how fast or slow the patterns should change. Ability to get the clock it’s self to choose,it will cycle through all the different display pattern options, if you want,or pick one at random, or you can get it to do a combo – e.g. display a time pattern, followed by an animation pattern, then pick a pattern at random, then repeat the whole cycle.


Wi-fi Configurable Clock

This clock contains a wi-fi system, which allows you to connect your phone, tablet, laptop or computer to the clock, and, once connected, you can change and configure what the clock displays, there are many different clock time patterns to choose from, and there are also lots of different animation display patterns to choose too. Once of the nicest features is the ‘cycle’ feature which rotates around all of the different display patterns in turn. There is a ‘random’ pattern feature too that chooses a pattern at random, each time the pattern cycles round. You can choose how long each pattern is displayed for before moving on to the next one, and you can also choose the speed at which the display moves. Slow speeds for moody relaxation, faster speeds for party time!

Planet Saving. Money efficient. Memory making.

We are keen to save the planet one products at a time! By buying a Retro Electro Designs product instead of something newly manufactured, you are contributing to saving the planet and supporting the upcycling/re-cycling movement.So, please, take a bow, and feel good about that!This product is made out of mid-20th Century item which was made to last. Metal, wood not plastic. We’ve worked hard to ensure our products also use a little electricity as possible. Hence LED’s. We’ve included a brightness control, less light out = less power used.
