"Lixie", an LED alternative to the Nixie Tube

Always jealous of people who could afford big Nixie Tubes, I rolled my own alternative with WS2812Bs and laser cutting!

Similar projects worth following
I've always been a fan of the Nixie Tube. Beautiful typography, endearing glow, and very clever technology. But when commercial production stopped in the 1990s, prices for surplus Nixie Tubes began to rise. Smaller tubes like the IN-16 are still only about $3.50/piece, but bigger and more desirable tubes like the IN-18 can run up to $45/piece. If you wanted to make a 6-digit clock, it can cost up to $270 just for the tubes! And they're potentially dangerous. And they might "burn out" next week. And they need special switching circuitry. And they're old news.

So let's modernize the Nixie Tube!

LIXIES ARE AVAILABLE FOR SALE AGAIN NOW!!!
https://www.tindie.com/products/connornishijima/lixie-an-led-alternative-to-the-nixie-tube/

Edge-lighting panes of acrylic etched with a design has been done for decades, but they've always been static information like an "EXIT" sign. If you stack multiple panes of acrylic (each with a unique design) and light them individually, you can change what design the user sees!

This makes edge-lighting perfect for a numeric display! And since I love the look of Nixies, we'll emulate the typography as well. At the end of the day, what I've made is a beautiful over-sized numeric display using WS2812Bs and a laser cut digit assembly!

We'll call it a "Lixie".

The Lixie has extremely simple setup, just connect the 5V, GND, and DIN pads to an Arduino and use the Lixie library to write a digit to the display! That's it! No HV switching, PCB footprint, or worries!

Since the Lixie is just wired like a WS2812B strip, you can connect the DOUT pin of one to the next and show a number as long you'd like!

Here is a video demonstrating the result:

  • 20 × WS2812B Smart RGB LED with daisy-chained control built in!
  • 1 × 1000uF Capacitor

    Take This Job and Shove It

    Let me start this off by thanking you all for the support and rally you gave for the Lixie. I was able to quit my day job to make these full-time - I can support my family, the amount of time I have to continue development has doubled, and nowadays I have to do my inventory audits in weight instead of exact quantities. I never dreamed any of this would happen.

    Thank you, Hackaday staff and readers.

    A Modern Spin On A Retro Tech

    With the extra time I have after letting Lixie become my full-time job, I needed to make sure the interest doesn't die out any time soon. This new ad campaign is centered around a slogan: "A Modern Spin On A Retro Tech" - as the Lixies are. To compliment the slogan, I'm running every ad using vintage graphic design & pop culture from the mid-50s to the late 90s! A certain decade has had a revival in the last 10 years - especially after the success of things like Stranger Things, Kung Fury, Halt and Catch Fire, and some reboot films we won't talk about. Let's not forget the synthwave we're often hearing in the air. So to start, we're putting Lixie in the 1980s. Don't get me wrong, there are HUNDREDS of advertising and design subcultures from the era, but so far I've only tackled two of them:

    Mid-80s Corporate Electronics Print Ad

    The layout was based on this Casio ad from 1986, the title is Kabel Black, and the slogan typeface is a free alternative to ITC Garamond, which Apple famously modified and adopted as a corporate font from 1984 to 2001 with the introduction of the iPod. (In fact, here's the very first iPod ad - which still used the old font!) This peculiar fake is just that - a fake! Because the Lixie was almost entirely consisting of CAD parts, a 3D model was already made. I've spent the last week building as close of a replica as I possibly could using Blender/Cycles rendering, which led to this result:

    Now I can make videos with impossible angles and settings far beyond my video gear and budget - that are still completely representative of the real product! They can be on a table in 1986, (above) in bright daylight (left) or total darkness. (right) In fact, the header image for this log was also rendered!


    Very Cheesy, But Somehow Extremely Cool

    Shiny beveled titles, hyperspace travel, fast motorcycles, and neon grids. I've always been a huge fan of 1980s sci-fi and their enthusiastic cyberpunk futurism. This video starts out normal, but will become a deliberately over-the-top 80s sci-fi/action/tech commercial! Of course, it's still a work in progress, and more is to come!

    I've just received some late parts from China, and the next Lixie batch will be ready in early August.

  • Lixie is back VERY soon!

    Connor Nishijima06/08/2017 at 01:38 2 comments

    Hello again!

    It's been quiet here, but not slow! I've invested profits from the first Lixie batch into my own laser cutter, nearly finished the assembly processes for a new batch of 60 units, and have heard great news from the users in the first batch!

    Laser Cutter

    Yes, I could have gone for a 40 or 50-watt Chinese CO2 laser. But I'm in an apartment, with understandably strict lease terms about heavy tools and toxic fumes. So I took the safe route for now and picked up a 4-watt diode cutter. It works for the birch and black acrylic, but isn't strong enough to work with the clear acrylic digits of the Lixies. I live in Utah, so I'll probably re-purpose it to cutting fancy parchment to make me rich in the rushed-marriage capitol of the world. ;)

    Rolling Order

    Since it's kind of a pain in the ass to wait a month or two between batch releases, Lixie production will be converted to a "rolling order" system. With some properly timed shipping, I can begin releasing 40 Lixies to the wild, every week. The demand is definitely there, considering both the launch and current waiting list have had over 600 units in each!

    But First...

    This next batch will be 60 units. A bit bigger than the last, it'll fund the extra upfront cost needed for the rolling order shipping.

    The next batch of Lixies will be released on June 12th, at 6PM MST!

    You'll be able get some at the usual place, the Lixie's Tindie page. Hang in there, they're coming back!

  • Lixie goes up for sale tomorrow!

    Connor Nishijima04/03/2017 at 01:48 0 comments

    Hello again, makers!

    It's been quiet here the last few weeks on Hackaday, but let me assure you that things haven't been slow! I've finished moving into a much larger space, tweaked my shipping needs a bit, and I have great news.


    The first batch of Lixie displays will be available for sale tomorrow on Monday, April 3rd, at 6 PM MST! (UTC-7)

    At first I will be assembling and selling in batches of 60 - leaving my day job once things pick up so that I can fulfill Lixies full-time. I must warn you though - if you want a Lixie now, you're going to have to be ready when it goes live. As of writing this, there are 658 units on the Tindie mailing list, and it grows by about 8-10 units a day. I'll be reaching out to the Tindie staff after launch for confirmation whether or not I've listed the most desired product in Tindie's four-year history. I'm dying to know! Also, I'm going to limit orders of this first batch to 6 units per address to make sure nobody buys half the stock in one go or something strange. (There's a user on the waiting list who wanted 36 digits, sorry man hang in there!) If you order more than 6, I will cancel the order. This restriction will ease up next round, but for now I want to make sure as many people get to try some as possible.

    So - to get you completely up to date with how the Lixie works and how to get one, let me list out some details:

    • Lixies will sell for $38/each for single units, $35/each in batches of 4-5, and $32/each for batches of 6 or more.
    • They can be purchased at MY TINDIE STORE at the time/date above.
    • Lixie has an official Arduino library for control, which is fully compatible with standard Arduino/AVRs, Teensy, and ESP8266. (I highly recommend the latter!)
    • The Lixie control library has a work-in-progress port for Python, allowing use with Raspberry Pi, CHIP, BeagleBone, or any other embedded Linux system that can directly drive WS2812B leds.
    • Lixie, out of box, can be used as a clock, weather station, system monitor, live website visitor counter, and anything you can think of.
    • Lixies are extensively tested before sale, and assembled with nitrile gloves in a clean environment to prevent fingerprints and surface damage to the panes.
    • The boards are reflow soldered with proper temperature profiles for both the solder and LEDs, to ensure maximum LED lifespan.
    • While the Lixies are free of any fingerprints, they may accumulate dust during their travels. The clear section of the display is separately wrapped in polyurethane, just spray an air duster through the side once it's unwrapped and you'll be good to go!
    • They are shipped wrapped in 1 sq ft of anti-static polyurethane foam (plus the foam wrapping the display section) and sent in ULINE "Indestructo" mailers, which are double-walled!
    • For those buying 4 units, they come in four mailer boxes, snuggly fit into a larger 7x7x7" box. Orders of 6 come in an 7x7x11" box, and any other quantities will be a mix or multiple of these.

    Tomorrow, I will be writing a full "Getting Started" guide on Github and sharing it here so that you can get started as soon as it arrives!

    I'd like to thank Katie Stockton for her never-ending support and patience for stacks of Lixie pieces all over the house, David Madison for his extensive work improving the Lixie Arduino Library with me, Hackaday writer James Hobson for sharing my work on the main blog, Donald Bell of Maker Update for the YouTube coverage, Lisa Horn, Content Manager at Ponoko laser cutting for reaching out to get the story, and the 18,000 viewers of these Hackaday.io logs for their supportive interest these last 4 months.

    THANK YOU!

  • Here is the final "Lixie"!

    Connor Nishijima01/11/2017 at 20:17 0 comments

    A few big things have happened, and the Lixie is better than ever!

    On the left is the original Lixie you all know. On the right is the final model, with two major changes:

    • The numbers are outlines, instead of a stroke. This essentially doubles the light catching area without hurting the final cost.
    • They are now engraved, instead of cut.

    Originally, I doubted the brightness of engraved vs. cut acrylic, and completely cut each digit through. Unfortunately, this only worked when viewed from an angle - the numbers would almost completely disappear when viewed straight on.

    Lixies are also less fragile now that each pane is a solid piece!

    All of you on the waiting list or joining it going forward will be receiving this better version, of course!

    Software Updates

    A wonderful help in the development process, David Madison teamed up with me to deliver an amazing Arduino library for Lixie Displays. Most of the awesome features are in the changelog, but here's some of the most important additions:

    • lix.max_power(volts,milliamps) This is an extension of FastLED that allows you to globally limit brightness of the WS2812Bs so that they never draw more than your power supply can handle! Under normal use, a Lixie can only consume up to 120mA when two LEDs are lighting a digit at full white. But sometimes you might want to flash ALL LEDs for a notification. If you flashed full white on a 6-digit clock, it would draw more than 7.2 amps!
    • lix.color_balance(CRGB c_adj) Sets a color calibration for the LEDs. Supports all FastLED color temperatures, and custom temperatures in the form CRGB(r, g, b). (Default: Tungsten100W / R: 255 G: 214 B: 170)
    • lix.get_leds() Returns a pointer to the CRGB array that holds the color values sent to the displays. The library's show() function overwrites the values in this array, so call FastLED.show() to see any changes.

    The biggest addition David brought was removing the need for a config.h file to define constants. Now that are set from inside the sketch!

    #include "Lixie.h" // Include Lixie Library
    
    #define DATA_PIN   13
    #define NUM_LIXIES 2
    Lixie lix(DATA_PIN, NUM_LIXIES);
    
    long count = 0;
    
    void setup() {
      lix.begin(); // Initialize LEDs
    }
    
    void loop() {
      lix.write(count);
      count++;
      delay(250);
    }
    You can also have multiple different sets of Lixie displays on a single Arduino that can be separately written to.

    Release Update

    Everything is still on schedule for a January release! I'll be ordering 32 units to start, and another 32 immediately after! Feel free to hop on the waiting list to get one on release! :) Thank you again guys for the awesome support and David for all the great pull requests!

  • Putting Lixie to Use!

    Connor Nishijima12/28/2016 at 15:17 0 comments

    Hello again, makers!

    This week, I've got an update on Lixie manufacturing, a new accessory in the works, and a bunch of cool code examples!

    Manufacturing Update

    I've ordered the final revision of the Lixie PCB for testing from DirtyPCBs, and as soon as it arrives and passes, I'm committing to a 200-unit run from Elecrow! I've already ordered 50-units-worth of every electrical part, and waiting until my next check to order all the laser cuts, so we're still on schedule for mid-January.


    Accessories

    A new development for Lixie is a daughter board, simply named "Lixie USB". This will bolt on underneath the first Lixie in your chain, and solder through to the input pads. As of writing this, it has an ATMEGA16u2 on board, which can be programmed with the Arduino IDE right over the USB port! You can also power your Lixies with micro-USB with this board. This allows for two types of setups:

    • Program any Lixie code you want straight to the ATMEGA, for a standalone system
    • Program a Serial JSON Parser sketch to the ATMEGA, and control Lixies over USB from a computer, Raspberry Pi, and more!

    Also in the works in an ESP8266 daughter board w/ microUSB for standalone WiFi Lixies!


    Lixie Project Examples!

    Because we're nearing the Lixie launch, I've gone ahead and begun programming a bunch of projects you can use right out of the box!

    NTP Clock

    https://github.com/connornishijima/Lixie-projects/tree/master/ESP8266/NTP%20Clock

    The most obvious use for Lixies is a clock! By driving these with an ESP8266, you can flash this for a self-setting NTP Clock!


    Live Wordpress/PHP Visitor Counter
    https://github.com/connornishijima/Lixie-projects/tree/master/ESP8266/Live%20Wordpress%20Visitors

    This is a live Google Analytics-style counter of active users on your Wordpress/PHP site!


    OpenWeatherMap Display
    https://github.com/connornishijima/Lixie-projects/tree/master/ESP8266/OpenWeatherMap%20Display

    Another good use for an ESP8266 connected Lixie is a live weather display! The temp/humidity/pressure is shown in the numbers, and the weather status (clear/rain/extreme/etc) is shown in the color!


    Ping Speedometer
    https://github.com/connornishijima/Lixie-projects/tree/master/ESP8266/Ping%20Speedometer

    Using an ESP8266, you can have a live network latency monitor! This code pings Google often, and shows you the response time in milliseconds. The Lixies are also colored a range from green to red based on latency good/bad thresholds you set!


    data.sparkfun.com Streamer
    https://github.com/connornishijima/Lixie-projects/tree/master/ESP8266/data.sparkfun.com%20Streamer

    I'll be adding more logging services soon, but for now you can stream a field of your choice from any data.sparkfun.com log! Lixie will show the latest entry of a numeric field, such as temperature, wind speed, CPU load, or any number you can push!


    Nest Thermostat Display
    https://github.com/connornishijima/Lixie-projects/tree/master/Serial%20Parser/Python/Nest%20Thermostat

    This one is a bit different, as it requires the Serial JSON Parser mentioned above, and a Raspberry Pi. Unfortunately, the only way to do more complex internet tasks like OAuth2 is by using a computer like a Raspberry Pi. Pretty soon I'll be porting the Lixie Library to Python so that you can drive a Lixie chain directly from an embedded computer, but for now you'll need the USB-Serial setup.

    Pi > USB > Arduino > Lixie

    This is a script that connects to your Nest Thermostat over their cloud API, and returns the current measured temperature, coloured by the system status: orange = heat, cyan = cool, white = off.


    EOF

    All of the above projects - and there's more every day - are on the Lixie Projects Github Repo. Once again, thank you all for the support, pull requests, and a big thanks to the 83 people on the Tindie waiting list eagerly awaiting the arrival of their Lixie displays!

    I've never been one to deliver lines well from a script, but here's a more personal update delivered in video! :)

    Here we see the awesome black WS2812B LEDs! Before ordering, I didn't even know they made these! Here is a view of two Lixies doing the "color count" test:

    Bought a second card table just for assembly!

    And here are some Lixies cooking in the oven! I highly recommend reflow soldering if you've never tried it, you'll save hours of your life with every product! ;)

    And here's a 360 view of a Lixie assembled with nitrile gloves in a clean environment like yours will be:

    Once again, thank you all for you support, and feel free to join the Lixie waiting list if you want to be notified on release in January!

  • Officially Open Source!

    Connor Nishijima12/12/2016 at 02:49 0 comments

    Today, the Lixie Display was officially deemed open by the Open Source Hardware Association! (OSHWA for short.) This means that a member of the OSHWA board has manually checked that I'm properly sharing all documentation in an open, (Fritzing) or "free" format. (Eagle Free Version)

    Because of this, I'd like to cover two things:

    • The OSHW certification process
    • Lixie's open hardware!

    OSHW Certification

    After seeing this wonderful talk by SparkFun founder Nathan Seidle a few months ago, I decided that the Lixie display would be as open as possible. There's nothing you can do to stop a copy cat, so you might as well be friendly!

    If your idea can be sold, it will be.

    On December 9th, I submitted Lixie's documentation (available on the Github) to OSHWA through their online form. The "Certification Mark License Agreement" took about 30 minutes to complete with reading to make sure I wasn't signing my soul to the devil, but I was very pleased with the terms. For those of you unfamiliar with the OSHW mark, it's fairly new and very cool!

    The OSHW logo is a new iteration of the Open Source Hardware "Gear Logo". This gear is still valid, but has one issue: anybody can use it. This means that people who weren't open sourcing at all were using the logo purely for promotional reasons. (Dave Jones has a great video about this.) The new [OSHW] logo solves this by requiring manual approval of it's use per project with their certification process.

    OSHWA replied within 48 hours, on a weekend, with my official OSHW UID of "US000054"!

    Please note however, the OSHW mark is *NOT* a licence protecting the hardware from being closed by a third party, it's just a certification mark. You'll still need to bundle in a licence like The GPL v3 I use on all of my work.


    Lixie's Hardware

    In the spirit of being as Open as possible, let's take a thorough look through how Lixie works!

    Concept

    Lixie works by shining light through the edge of a clear acrylic. When the light hits an engraving or edge, it scatters in a different direction, and lands in your eye! This allows the flat surfaces of the acrylic to stay clear, and have only edges light up! Now put ten pieces in a stack, each marked with a different number 0-9, and you can show each number individually, on a clear surface!

    To do this well, we need two things: plate separation and a light filter. Adding a gap between plates prevents light from jumping between them, and a filter at the base prevents an LED from lighting any plates but the one it's supposed to.

    Plates

    Each of the ten plates has a number on it, 0 through 9. For maximum light output, these numbers are actually cut all the way through the acrylic, with little connected areas left on numbers like "9" so that no areas are completely cut out. (Think pumpkin carving). Most laser cutters are able to produce cuts of a certain depth as to not completely cut the material, but I use Ponoko for cutting these, which only allows very shallow engraving or full-blown cutting. Each plate is separated by a 1mm air gap.



    Filter

    A light filter is used to prevent LEDs from lighting plates they shouldn't. Each plate has two legs leading down to two slots, over two LEDs. This filter, and the PCB beneath it, are specifically designed so that the three anodes of the 5050 RGB LEDs are centered under the slots.

    Printed Circuit Board

    The Lixie actually has a very simple PCB, with some very specific dimensions. To fit all of the LEDS in, they have to be staggered diagonally. Each acrylic digit has the two lightpipe legs in different spots for this reason. As mentioned above, the LEDS are also placed JUST right so that the anodes for red, green, and blue are centered under the filter slots.

  • Hello again, world!

    Connor Nishijima12/08/2016 at 19:54 0 comments

    Since we last talked, Lixie's software has undergone some major changes! Let's jump in.

    • The library has been rewritten from scratch! This includes some big improvements like...
    • LED states have been reduced to almost 1/8th their original size! Before, each binary state was stored greedily in it's own byte. Sloppy programming. This meant the LED states of a single digit took 20 bytes! :( Now, a much better system of storing the binary states in the actual BINARY of a byte is here. A single digit now only takes 3 bytes! (20 states, 4 bits left over)
    • Lixie now has HSV color space as well as RGB! Use either that you'd like. :)
    • Numbers are no longer converted to char arrays for pushing out the data, it now does this mathematically with division.

    Along with software changes, a few have been made to the project itself. I am considering including a custom cut piece of black cardstock that users can shimmy into the assembly behind the rear digit to increase contrast if necessary. If you don't need it, it makes for one cool transparent display!

    Also, somebody requested I show the Lixie in a brighter environment so we could see how it looks during the day! Here is a Lixie (with all 10 digits now) cycling through colors in the daytime!

    More details are to come! Thank you all for the awesome support so far!

Hallo, more than 10 years ago I build a really Nixie clock with russian IN18 and it works until today.  Therefore I am very interested in this project. I have ordered a view days ago 4 Linie modules and wait for it. In preparation I have flashed the Linie_NTP_Clock.ino to a NodeMCU 1.0(ESP12E-Module) with the Arduino 1.8.1 IDE. The IDE Monitor shoes this lines and I think it is ok.:

Starting UDP

Local port :8888

waiting for sync

Transmit NTP Request

us.pool.ntp.org:69.164.202.202

Receive NTP Response

11:06

11:07

11:07

On the pin 5 of the NodeMCU I have connected WS2812BLED's. But there is no result, not DIN signals to the LED stripe. The NTP_Colck.ino is the latest release from GitHub (I hope so) with " #define DATA_PIN 5 " line.

Dear Connor, Have You an idea what can be wrong ?

And one more Question : What is the height of the digit number. I only have found the dimensions  of the Acryl panels , not from the numbers.

Best Regards from Germany

Have you thought of doing a 14 segment display style? Each of the panes consisting of a segment that can create an alpha numeric character while lit with certain neighbours?

  Are you sure? yes | no

Connor Nishijima wrote 06/25/2017 at 15:56 point

I have some ideas for this - but I've yet to prototype it. The tough part of making this a segment display is that the difference in depth between panes can cause some unwanted distortion to the number/letter being shown. However, with the air-gap between digits removed this can be somewhat mitigated in exchange for some extra light bleeding.

  Are you sure? yes | no

Matthew Potter wrote 06/27/2017 at 20:00 point

I’m thinking to incorporate the joints in each of the segments may be an option… a small overlap in all of the possible variants. Picture a slightly larger circle where the joins would normally be. Planning out the order that best suits angle of view would be key though. Bottom segments at the top, top segments at the back if you’re planning on having it lower than eye height… it would be something to play with and see what works best for sure.

Any reservations in me trying it out if I can get my hands on some spare acrylic? I’ve got everything else handy including access to a laser cutter.

  Are you sure? yes | no

Are you the same Connor Nishijima that bailed on his Kickstarter backers? Hope not, this is a cool project.

edit as I should probably add: Good to see another's interpretation on the idea - I just finalising documenting my project to release to the world when someone notified me of your project. Useful to see the OSHW certification process too, it's something I'm going to look at. Here's my design blog too by the way: http://engineer.john-whittington.co.uk/2016/12/nixie-pipe-modern-day-led-nixie-tube/

No worries! I'm not here to shut you down, in fact I really like them! :) My advice is that you need to add "edge lit acrylic nixie led" into your SEO tags, I was never able to find those in my research.

Cant wait for the followup files.  I would love to put a few of these in upside down mason jars and make a redneck nixie tube clock.

Neat! What size ws2812s are you using? I recently found out they come in a 3535 package. You could probably make it more compact with these babies: https://www.adafruit.com/product/2686

great idea... You should make some smaller ones with tubes and do a clock

Was never a huge fan of nixie tubes, but this is very slick!
