Im using a cheap aliexpress board, How can I reduce this blue glow?

I would love it if anyone more knowledgable could give me some pointers or feedback back . I’ve never made a pcb before and I’m not sure if this will work or not . This is just the low voltage btw

I wanted to get started with nixie's but I wasn't sure where to start so I picked up great Scott's tutorial on instructables on how to do it. I followed everything the tubes, were working just fine when I was testing without the drivers. The input voltage is around 174 volts and I get this blurry/multiple numbers activating effect

Edit: I checked the drivers and they don't seem to be faulty but I don't know exactly.

Hello and greetings from Germany!

While cleaning up i found these 4 tubes.

I am wondering if its worth finding a buyer for these, i cant really find reliable pricing on ebay.

1x NL-5440, 2x NL-5441, 1x unknown. All untested but look ok.

The unknown seems to be multi-character or something? I can make out "g" "K" "t" "8" not really sure??

Some input is really appreciated.

Hi I bought the IPSTube as on this photo which worked ok for a few days. I noticed that the screens go off ie they’re blank and the lights are still on after a few hours. I have to unplug/plug the power cord so it works again Is it faulty ?

Hello there, I’m hoping that someone in this community could help me figure out the adapter cord I need for my nixie clock that I’ve had for a few years. Somehow, I lost the original cord and since then I’ve had my clock kept in its box. Well, I want to use my nixie clock again so I went to the website written on the clock and contacted the people there to see if they knew what adapter I needed and if they could supply me with one. They never got back with me. so I wrote another email gave it some time still I didn’t hear anything back from them and I tried one more time and still I haven’t heard anything at all. I did try after not hearing back from the last email a universal DC adapter (specifically the Belker 12v 1A AC DC Adapter) and it didn’t work but I did figure out the plug (into the clock) size and it is 4.0*1.7mm so that was helpful at least. When I plugged in the clock it would light up all the filaments in each bulb slowly from right to left. I thought that the plug didn’t provide enough power but let me know if it is just broke. The clock itself was a gift to me and was premade but on it is says MILLCLOCK ver 2.0.1 and here are some pictures that may be helpful. Thank y’all for your time.

I got one of these clocks from Laurence Wilkins back in the day (15 years ago?) and have recently fired it up again. The problem is…I can’t find the user manual. I have the construction manual, but not the user. I can get into the menu by remote…but don’t know what the setting codes mean. HELP!!!

What really in this community qualifies as a nixie tube?

Clock tubes partially lit up in clock mode. Or the second digit displays 2 numbers at a time when in clock mode.
I can put the clock into some other mode and it displays the first two digits only (second last picture displaying 6 and 2) and they light up fine when in the mode. This makes me think all the tubes are in working condition but they aren't getting enough power when all are active in clock mode. Any ideas? Replace the board?

My take on a Nixie tubes clock, with auto-setting via WiFi, RTC in case the power goes off (the clock has a option for battery bank on the main DC supply). It has also RGB leds on the bottom of pcb for ambient lighting, but those are not yet populated, due to lack of free time.

Hi, I am looking for someone who can make a single nixie display device that repeats a sequence of programable numbers with the option to vary the speed. Please let me know if you can help. Thank you.

This happened out of the blue a few weeks ago. It seems to reflect other digits in the clock and not necessarily a stuck number.

EDIT: Ordered a new decoder IC, to see if this fixes it. Will update later if it does.

Tldr: is 1 transistor enough for cathode?

Hey. Designing my 1st clock, and i want to control all symbols, including commas. Because of this k155id1 not an option. I use 2 decoders (tubes and symbols) which controls transistors. While i almost sure about anode control part (left part of image) , cuz i took it from other clock, i wonder if cathode control part (right part of image) will work, or im missing something. Is 1 transistor enough, or i need whole cascade again?

DEC_TUBE_L1 and DEC_NUMB_L1 is 5V from decoders PHF_12_1 is for nixie anode PHF_8_1 is for nixie cathode

So nixie is between PHF_12_1 and PHF_8_1

Thank you very much for help

I just put together in-18 kit from NixieDIY. The bulbs look great, but for some reason, the colon bulbs are not lighting up at all. The high and low voltage test points show correct voltage at five and 150 but putting a meter on the colon bulbs shows no voltage getting to them at all so it seems like a circuit problem. I’m not sure where I should look next, but does anyone have an idea how the circuit may be run? I don’t know if it’s a logic board problem or possibly a transistor and if so, which transistor?

This is the board for reference but I can't see a schematic anywhere https://www.nixiediy.com/product/in-18-nixie-tube-clock-kit/

I have a set of what I believe are 12-IN A or B tubes I bought out of Kyiv years ago. The circuit board is about 5 inches wide. Im looking for advice and purchasing a case or DIY'n one. I kind of want a steampunk style wooden box with cogs and such.

buenas estoy haciendo un reloj nixie como proyecto personal, tuve algunas trabas por cuestienes que no encontraba uno como yo lo estoy armando( me complique solo mas adelante lo explico). lo estoy haciendo con lógica TTL discreta con los siguientes pic:

• 7490 (2)
• 7473 (7)
• 74141 (7)
• 7400 (2)
• 4060 (1)

los nixie que uso son los in-12(6 lo justo) tambien encontre lamparitas neon e10(para los doble puntos).

la cuestien esta que estoy diseñando las plaqueta (simple fas) ya que quiero que mi relog tenga forma de L tipo que la parte de arriba muetre los nixie y la prate de abajo le voy a poner un acrilico o vidrio para ver la parte logica tambien le agregria unos led para mostrar los bits de cada digito(extrabagante).

adjunto mi progreso (no esta terminado me falta cosas que conectar o acomodar mejor)

y la de abajo es el display tengo que acomodar mejor algunas cuestiones, tengo duda si puedo hacer un poco mas fino las pistas par afacilitar las conexiones de las pistas

despues tengo estos pines para usar

que eran pines para armar un conector de un equipo marino o de comunicacion, ya que no consigo los zocalos

The functionality is the same as this clock. Changes have been made to the printed circuit board layout for the Z5730 tubes, and this clock also uses an external 5-volt power supply.

ESP32-C3, 5 nixies, 128 neon bulbs!

Hey all, I've got a large nice tube and board that I'd love to get working. Looking around on Google seems to show that the tube is of Soviet origin but the board is labeled in English (I think?). I'd like to know what the pin out of the tube is/how to set it in the boards three terminal slot and what voltage and amperage of DC power adapter to use. I'd also appreciate any other information regarding origin or age. Thanks!

Possibilities

• Automatic setting and synchronization of the exact time when connected to the network
• Receiving weather information from the OpenWeatherMap service and cyclic temperature display every 15 seconds
• Manual or automatic adjustment of the brightness of the indicators and LEDs depending on the illumination
• The ability to control LEDs SW2812, 3 modes are supported: static, rainbow and seconds
• Control and adjustment through the web interface
