Us: “I’ll take Retro style displays we absolutely have to have for $200, Alex.”
Trebek: “This nixie tube is unlike any conventional tube you’ve seen before, handbuilt and NOT numbers or letters.”
Us: “What is FriendlyWire’s new logo tube?”
Trebek: “Heck yeah.”
Nixie tubes are the vacuum technology that manages to do far less than a graphic LCD while looking about a million times cooler. Generally speaking, these tubes are no longer manufactured, and the old stock you can get your hands on usually contain a set of filaments shaped like numbers. But @FriendlyWire’s tweet of this Nixie tube by [Dalibor Farny] breaks both of those rules. This handmade tube isn’t just a numerical display or a colon display (the punctuation mark, get your head out of the gutter). It’s a custom logo, and it’s beautiful.

Engineering creativity comes to life when you have to design around a set of constraints. We can do just about anything with enough time, talent, and treasure, but what can you do when shackled with limitations? Some of the most creative electronic manufacturing tricks spring to life when designing conference badges, as the ability to built multiples, to come in under budget, and most importantly to have the production finished in time are all in play.
This happens at conferences throughout the year and all over the globe, but the highest concentration I’ve seen for these unique pieces of art is at DEF CON every year. I loved seeing dozens of interesting projects this year, and have picked a handful of the coolest features on a badge to show off in this article. I still love all the rest, and have a badge supercut article on the way, but until then let’s take a look at an RC car badge, a different kind of blinky bling, and a few other flourishes of brilliance.

Three years ago we covered [Dalibor Farnby]’s adventures in making his own Nixie tubes. Back then it was just a hobby, a kind of exploration into the past. He didn’t stop, and it soon became his primary occupation. In this video he shows the striking process of making one of his Nixie tubes.
Each of his tubes get an astounding amount of love and attention. An evolution of the process he has been working on for five years now. The video starts with the cleaning process for the newly etched metal parts. Each one is washed and dried before being taken for storage inside a clean hood. The metal parts are carefully hand bent. Little ceramic pins are carefully glued and bonded. These are used to hold the numbers apart from each other. The assembly is spot welded together.
In a separate cut work begins on the glass. The first part to make is the bottom which holds the wire leads. These are joined and then annealed. Inspection is performed on a polariscope and a leak detector before they are set aside for assembly. Back to the workbench the leads are spot welded to the frame holding the numbers.
It continues with amazing attention to detail. So much effort goes into each step. In the end a very beautiful nixie tube sits on a test rack, working through enough cycles to be certified ready for sale. The numbers crisp, clear, and beautiful. Great work keeping this loved part of history alive in the modern age.

The handlebars of this Honda CL175 ended up being perfect for holding two Nixie tubes which serve as the speedometer. There are two circular cavities on the front fork tree which are the same size as the Nixies. Wrapping the tubes in a bit of rubber before the installation has them looking like they are factory installed!
This isn’t a retrofit, he’s added the entire system himself. It starts with a hall effect sensor and magnets on the rear wheel and swing arm. Right now the result is 4 MPH resolution but he plans to add more magnets to improve upon that. For now, the driver and speedometer circuitry are hosted on protoboard but we found a reddit thread where [Johnathan] talks about creating a more compact PCB. If your own bike lacks the fork tree openings for this (or you need help with the drivers) check out this other Nixie build for a slick-looking enclosure idea.
The link at the top is a garage demo, but last night he also uploaded a rolling test to show the speedometer in action. Check out both videos after the break.

[Johannes] wanted to develop an unusual way to display time on a custom wristwatch. LED’s were too common, and mechanical indicators with small engines were too expansive, but Nixie tubes were just right. His design for the Numitron Geekwatch utilized two boards that were soldered together at a right angle, with a 3D printed enclosure made of semi-transparent PLA.
Future designs of this will improve on the button functionality as well as the housing of the wristwatch to protect the fragile tubes from external forces.
After the break is a video (in German) with [Johannes] going through the steps needed to make one of these of your very own:

[Reboots] is a humble hacker who enjoys nixie tubes. So when he saw an old General Electric battery charger for sale at a hamfest, he thought: “that case would make a nice clock…”
He was first exposed to nixie tube clocks a few years ago when his brother gave him a DIY nixie clock kit from [Peter Jensen’s] website TubeClock.com — it was an easy build, and worked very well. It also introduced him to a unique driver for nixie tubes, an HV5622 high-voltage shift register made by Supertex inc. Compared to the traditional (and rare) 74141 nixie driver chips or discrete transistor drivers, the HV5622 is much smaller, requires less microcontroller I/O’s, and is not as picky when it comes to powering it.
The nixie tubes he chose for the project came from a lot sale on eBay, Russian surplus IN-12 tubes. He even managed to find an english datasheet for them!

Do you love Nixie Tubes? Upset that they aren’t really manufactured anymore, and the cost of old ones is rising? Why not make your own? That’s exactly what [Dalibor] of the Czech Republic is up to, including blowing the glass tubes himself!
He’s chosen the Z568 nixie tubes to copy, as they are his favorite style of nixie. To create the display he has etched the digits and housing out of 0.3mm stainless steel sheet — which potentially means if he gets the hang of making the tubes, he could actually produce them to sell! To perform the glass blowing, he scored a Heathway glassblowing lathe off eBay — but unfortunately he hasn’t documented much of anything on making the glass tubes, which is too bad because we think that would be equally fascinating as the nixie displays themselves. On his first attempt with a properly sealed tube, the nixie worked and he even recorded striking voltage values very similar to industry tubes — not bad for something made in a backyard shed!
He has since then continued refining this art and is entering a glass-art contest called “When Prague Meets Shanghai” with a beautiful entry dubbed the ShanghaiTime Nixie Clock.
If this post seems vaguely familiar, it’s because this isn’t the first time we’ve posted an article about homemade nixie tubes, but we think [Dalibor’s] is by far the most elegant! Stick around after the break to see one of his first test videos — You might even think he’s cheating, the tubes look so professional!
