    Everyone loves the look of Nixie tubes, with their glowing orange characters made of curvy filament. But we usually only see makers using Nixie tubes for one purpose: clocks. That’s unfortunate, because they have a lot more potential, as illustrated by Bob Cascisa’s Nixie tube slot machine game.

    This is a really delightful device that puts the slot machine experience into a handheld form factor, with a beautiful Nixie tube display. It has a single button to spin the “wheels,” and seven Nixie tubes to show the action. The top three Nixie tubes represent the wheels and they cycle through distinct symbols. The bottom four Nixie tubes show the player’s balance to keep track of payouts.

    The bottom Nixie tubes are IN-12 models, which are Soviet NOS (New Old Stock) models capable of displaying numeric digits. The top Nixie tubes are rarer IN-7 models that can display a handful of symbols that would be useful for lab instruments, such as ?. Cascisa chose those IN-7 tubes because their symbols have a more iconographic appearance than standard alphanumeric characters, which English-speakers would try to read.

    An Arduino Nano board controls the gameplay. It plugs into a custom PCB that Cascisa designed to house all of the components necessary to drive the Nixie tubes — a difficult job compared to modern LED and LCD displays. It requires a power supply that can provide high voltage to the Nixie tubes. Power comes from an 18650 battery pack inside the simple enclosure, with a charging port on the side. 

    By Vegas slot machine standards, the gameplay is pretty simple. But this unit’s Nixie tube display certainly looks much nicer than the retina-scarring graphics on those machines.

    Nixie tubes are fun little devices that act like seven-segment display modules in that they can be lined up together in order to form a larger number by showing digits 0 through 9. One maker, Marcin Saj, has created a unique project that uses a series of six Nixie tubes that can show the current time, temperature, and humidity all within a compact footprint. It is also able to receive commands via the Arduino Cloud service and an Alexa skill, thus enabling users to toggle various functions on or off with a smart speaker or phone. 

    Saj’s IoT Nixie Clock Shield has an RGB backlight that can be easily adjusted via the Arduino Cloud’s RGB color picking tool, which allows for the device to match almost any environment. The built-in Nixie power supply is great as it lessens the chances of being shocked with 170V, and each tube is user-replaceable if it fails. The shield’s PCB has a header for plugging in an Arduino Uno, Nano, or Micro board, but it is best used with the Nano 33 IoT for cloud connectivity. The onboard DS3231 real-time clock module is able to keep the time accurately even when the power to the rest of the clock is removed.

    You can see more about this project, including its schematic and codehere on Saj’s product page. Also be sure to check out his demo video below!

  • Geometric Nixie tube clock and environmental display

    Creators keep coming up with new clock designs, and while you might think that every new possibility has been exhausted, Christine Thompson has proved this assumption wrong once again with her “VFD Trilateral Clock.

    This Arduino Uno-powered device employs a stepper motor to rotate a triangular prism shape with scales for hours and minutes on one side, temperature in Celsius and Fahrenheit on the other, and humidity and pressure on the third surface.

    The geometric scale travels in 120-degree steps, causing each face to line up with a pair of IN-13 Nixie tubes on either side. These linear tubes are then used to indicate time and environmental conditions in a beautiful bell jar display, as seen at around 3:30 in the video below.

    While waiting for the delivery of parts for another project I decided to push ahead with this project. At its heart is two IN-13M Nixie tubes. These tubes are designed to provide a linear scale between maximum and minimum points using an illuminated column. The project uses two of these IN-13M, three wire Nixie tubes to show, time (Hours and Minutes), temperature (Celsius and Fahrenheit), Humidity (percentage), and Pressure (millibars).

    At this point I would like to thank Dr. Scott M. Baker for his great web site, which provided me with all the information I needed to get these Nixie tubes to work. In particular the Current Regulator as displayed and detailed on his web site.

    The project uses a BME280 sensor to determine the temperature, pressure and humidity and RTC clock to monitor time. As the system needs to display six different values it was necessary to construct a rotating central display which showed these values against six scales. In order to achieve this an equilateral triangle of wood was fashioned, each side showing two sets of values. A stepper motor was mounted under the top platform and this motor rotates through 120 degrees in time for the next set of values to be displayed on the two Nixie tubes.

    Vintage-style clock made from individual LEDs

    Arduino TeamNovember 6th, 2018

    If you’ve ever wanted a vintage-style timepiece, or to test your soldering abilities, this clock by YouTuber Electronoobs will let you do both at once. 

    It features four display modules that resemble Nixie tubes, each made out of LED filaments soldered onto a steel wire frame. If you find soldering enjoyable and relaxing, this is likely a good project for you; though if not, there are of course other options. 

    The device is controlled by an Arduino Nano, along with a MAX7219 display driver to power the LEDs as needed. An RTC module keeps things “ticking” at the correct pace, and a pair of buttons on top of the wooden enclose allow the time to be adjusted as needed.

    I’ve made some “Nixie” tubes. These are actually 7-segment displays made with filament LEDs but placed in a plastic bottle so it will have a more vintage nixie look. To control the LEDs I’m using the MAX7219 driver that could control 4 x 7-segment displays. To get the real time, I’m using the DS3231 module that works with an I2C communication so it’s easy to use. The project also has 2 push buttons to set the hour and minute. All is inside a wood case painted with varnish so it will look more vintage.

    Check it out in the video below, or see the build write-up for more info.
