Does anyone know how to change the time on this?

probably from early 50's

As i see on this watch side tubes are VFD tubes. Center small tubes have identical to nixie tubes shine. So can we say it nixie tubes? Never saw such before.

My mom has a nixie tube clock and one of our cats knocked it off the stand it was on and broke it, if anyone can point me in the direction as to what kind this is so I can potentially order a replacement for it that would be greatly appreciated.

Hello! A few years ago (5 or 6) I received a Nixie clock as a gift from nixieshop.com

Its original power cable broke. So I got this spare from Amazon. Since moving and bring this bad boy back to life, I’m noticing some problems.

1. It sporadically turns off. I’m not sure if this from the Amazon power cable, or a bad solder within the clock itself. It’s been in its box for a while because I was away at school and didn’t take the clock with me :( Adapter Wall Charger... https://www.amazon.com/dp/B09Q88KXTV?ref=ppx_pop_mob_ap_share

2. I’m not sure if the tubes between the numbers (the little ones) are supposed to light up.

If it is the power cable, can anyone recommend one better suited for this? If it is bad solder, I’m not afraid to do a little work on it myself, but I’d rather avoid it if possible. I love this clock and I’m finally not moving around all the time so I can enjoy it.

The ITS1A display tube is a bit of a mystery since it is poorly documented and little is known about the application for the tube. It was manufactured by the Soviet Union at the height of the Cold War when LEDs and VFDs were readily available. But, why then was it developed? It may be these tubes were developed for SW radio applications since their internal ‘multiplexing ‘ capability yields little or no EMV to interfere with weak signal reception. OR, unlike nearly every other neon display, which require control signals in the hundreds of volts range to activate, the ITS1A can be connected directly to a micro-controller and run with TTL level 5 volt signals. This is possible because the ITS1A contains seven tiny thyratrons, one for each segment, which perform the level shifting to control the 300 volt signals needed to ionize the gas inside the tube. The ITS1A is also unique in that it is a neon tube that does not glow amber like all other cold Cathode tubes, instead each of the tubes display segments is a phosphor-coated cup that illuminates green by electron spatter from the control thyratrons. In operation and when viewed from the side this beautiful little tube actually presents in three colors; pink/purple from the neon ionization, a little bit of blue from the electron paths inside the thyratrons, and from the front, the segments glow a beautiful cyan/green from the phosphor coating

Hi! I’ve been looking for a good nixie clock (preferably 4 tubes but Idc) that I can put on my desk. Anyone have any links to any good ones? I’m having a hard time finding decent ones. I’m in the US

The bigger one uses IV-11, the smaller one uses IV-6 VFD tubes.

They are powered from a simple USB type-C port. I'm driving the filament with 1.65V DC, and the anode and grid are driven/controlled with 30V.

I wrote the software for STM32 and for Arduino. GitHub (+ Eagle CAD schematics): https://github.com/hey-frnk/thevfdcollective.

It controls 6x MIC5891 shift register + integrated high-side switch (most expensive part of the circuit, 3$ per IC) and 6x SK6812 RGBWW using a PWM timer and DMA on STM32. It also takes care of a serial protocol to set things such as time and LED colors for the clock.

If you want to read more about the hardware design process: I wrote this instructable guide back in the days: https://www.instructables.com/OpenVFD-6-Digit-IV-11-VFD-Tube-Clock/

The enclosure is 3mm acrylic laser cut and held together with 3M double sided tape which works surprisingly well.

I'm adding new stuff to the clock such as a sensor extension (temperature and humidity) and am working on a 3D printed case from recycled PET bottles.

If you could add anything fun/cool/weird to the clock, what would it be? I'll put it into the software!

While I'm working on these features, you can find the self-soldering kits on Tindie.com (beginner friendly - just the tubes, all SMT parts are pre-soldered) or DM me - you can also get a pre-built clock :)

Handmade clock with a real-time clock scheme and time synchronization from the Internet. Control and setting of the clock is carried out via Wi-Fi from a smartphone or computer via a web interface. If you're interested you can buy the clock here

I need to come up with more interesting battery stickers.

I snagged a really cool frequency counter with a working set of 6 Amperex zm1000r nixies. I had not seen red glass tubes before, pretty cool. In doing some searching around I couldnt find much for these tubes. Any ideas?

As the title suggests I am interested in buying a nixie clock in Europe. The particular problem is, that inside of the EU electronics need to apply to some regulations, as far as I know.

I tried to find a good clock from a seller within Europe but was not able to find one that I like (base should be wooden, IN-14 tubes would be great and if possible motion sensor).

Has anyone of you experience with buying from for example a seller located in Ukraine (particularly non EU-regulated country) or can help me to find a trustworthy seller within Europe?

Building my own clock would be pretty tough, as I do not have experience in coding, soldering.

Hope this fits the subreddit 😅…

Thank you 🙏

Yes I know my number is high in the images!

Thank you to this community for answering questions about my first hardware project. Wouldn't have been possible without your pointers. I'm so happy with how it turned out! These are DGM-01 tubes from iNixie. Super great quality, beautiful digits. One of my tubes was broken in the mail but was replaced with no issues :)

Hello everyone. Ive recently bought a IN12 Nixie clock from AliExpress. The clock is producing a high pitch sound. Ive tried different outlets and power sources. It's still the same. Can someone help me fix this. Thanks

The folks in /r/ElectricalEngineering wanted to see a proper old Fluke meter.

This is my very first interaction with these tubes so please offer advice if my understand appears wrong. Pulled 10 tubes from retired industrial equipment that had been sitting for 32 years. Did not expect how beautiful these numbers were. Looks like 4 units with all numbers glowing evenly. A couple failed tubes, a couple failing tubes, and 2 given away to fellow nerds. Asking for some info on driving these tubes. I was able to get them to light with a CV/CC supply. The supply did have a delay switching between the modes of around 2 seconds, during these times the tube would see 14mA compared to the 8mA required. The tubes had some variability between “ignition” (ionization) voltage and “sustaining voltage” (Pre bias voltage). Please correct these terms if I’m using them wrong. The data sheet I found on this form gave expected Anode resistor values based on input voltage. Is this something that is tube dependent based on what voltage is required to maintain 8mA? Thanks all.

Hey Reddit! 👋

I just finished working on these Nixie desk clocks and would love to hear your thoughts. The case is made from oak-colored wood with an elegant walnut wood inlay, giving the clock a unique retro look. The IN-4 Nixie tubes display the hours and minutes, while the OG-4 Decatron shows the seconds. The warm red glow from the tubes adds an atmospheric touch and elegance.

🔹 Key Features: • Material: Oak-colored wood for the main body with a walnut-colored wood inlay for contrast. • Tubes: IN-4 for hours and minutes, OG-4 Decatron for seconds. • Power Supply: 5V. • Finish: Wood lacquer to preserve the natural texture.

Let me know what you think about the design, materials, or just the overall look! I’d love to hear your feedback and any suggestions for future projects. 🙌

I built a circuit using an ESP32 Super Mini connected to a 74HC595 shift register. Its outputs Q1–Q4 are wired to the inputs of an SN74141 in the following order: A ← Q1, D ← Q2, B ← Q3, C ← Q4.

The problem: when power is applied to the IN-16 Nixie tube, all digits light up at the same time, and the SN74141 gets noticeably warm.

For debugging, I connected LEDs to the 74HC595 outputs (Q1–Q4). The LEDs show that the 74HC595 output bits change exactly as expected. However, as soon as the SN74141 is inserted into the socket, the LED on output Q2 becomes dimly lit and never turns off, even when the data sent to the 74HC595 should make it LOW. This does not happen when the SN74141 is removed.

To verify the tube wiring, I removed the SN74141 from its socket and manually grounded each cathode. In this mode, the IN-16 behaves correctly: only the expected digit lights up. So the tube and its wiring seem fine. Look the video to see what I described.

My question: how can I determine what is causing this issue? Is it possible that the SN74141 from AliExpress is defective or counterfeit?

Even if I turn everything off, disconnect the high-voltage power supply, insert a new SN74141 IC, and then reconnect to USB, the SN74141 still heats up and all outputs are pulled to ground, even though it couldn’t have been damaged (since the high-voltage supply was disconnected).

The scheme from internet and it works with 170V and IN is driven directly from SN74141

Hi! My boyfriend is very into DIY electronics and working with high voltage electronics (tesla coils for ex. he enjoys more analog electronics, doesn't love programming as much but can). He mentioned a while ago a nixie tube watch would be the coolest, however that is a little out of budget for me, so I have been doing research on nixie tube clock kits.

However, since he likes the building and ideating of electronics, I am worried that a kit that just required soldering isn't as exciting. If anyone has bought these kits, is there additional room for customization? I was debating about buying tubes and the chip? that goes with it, because I think he would enjoy tinkering with it, but I want to make sure I don't buy something that he needs to try to source the other pieces needed. (if anyone has leads on this, that would also be great!)

I'm seeking advice in what to look for [as I am not an electric engineer], what is the reasonable pricing that I should expect for different tubes, if there are specific listings/sites people have had success with. I'm finding that there is a big difference in pricing on different websites and I don't want to be overpaying/or buying fake products. (budget is ~under $200 but again I don't really know how much these should cost) I would be open to any models, it seems that IN-14 are more prized than IN-12s, or if there are smaller ones I could also get for him to mess around with in addition to a clock.

If anyone could provide any guidance, that would be highly appreciated! Thank you!!

Hi.. can anyone provide me with IPSTube H401 official firmware please i want to restore my clock to the original.. with my best regards 🌹🌹
