My nixie clock has a switch, with three level, full - low - off. The low level setting does make the tube look a bit dimmer. And the current seems to be slightly below specification. For all I know, it's probably not good for "Cathode Poison", but I can switch back to full level to flush them.

I bought a dozen of these a few years ago for a future project, and I've always wondered what these Soviet-era CRTs were used for. Too small for an oscilloscope, and very limited use as a text display. Seems unlikely they would be used for images, because they use deflection plates, rather than

Re: [neonixie-l] What does your shop look like?

Great idea, looking forward to seeing all your workshops! I have finally been able to set up a small workbench in my student's dorm as well. The problem is that I cannot bold anything to the walls, so I have to be creative. I am still starting out, but this is what I have so far. Cheers Jens

Re: [neonixie-l] What a find!

The software just runs on an Arduino (or maybe Wemos) and you attach a probe to the pin on the Arduino. There is no PCB involved, but as I said, the results aren’t great. > On Apr 22, 2019, at 9:17 PM, martin martin wrote: > > Hey Paul, do you have a PCB for what you made for your counter?

Re: [neonixie-l] What a find!

Hey Paul, do you have a PCB for what you made for your counter? I'll buy and we can save the counter from "Nixie Harvesting" ;) On Mon, Apr 22, 2019 at 3:35 PM Paul Andrews wrote: > I just attached the probe from the counter to the pin I was toggling. I’m > not sure how your unit would work.

I just attached the probe from the counter to the pin I was toggling. I’m not sure how your unit would work. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group and stop receiving emails from it, send an email to

Re: [neonixie-l] What a find!

Hi Paul, This instrument is an odd counter and programmable timer. If you look close you’ll need the dials yo pick your time interval. I am not a programmer at all. I did in college but that was long ago. If I were to modify it wouldn’t I have to cut circuitry? There’s a pic of the TTL in

Re: [neonixie-l] What a find!

I spent a little time developing a frequency generator yo display the time on frequency counters. Here’s a link to my write up: https://www.nixies.us/2018/03/25/display-the-time-on-an-old-frequency-counter/ Ultimately, not something I’d recommend, but fun anyway. -- You received this message

Re: [neonixie-l] What a find!

Yeah you could drive the counter with a frequency generator circuit or something similar to display time. If it works I would try to preserve the originality of the whole unit! Showing time could readily be accomplished with an ESP, Arduino, or similar for 10 bucks in hardware. What tube type

[neonixie-l] What a find!

I found this in a surplus store in Los Angeles. Berkely 6401 Programmable Counter Timer. Built in about 74-75. Completely designed with TTL all in sockets too. That's 9 perfect 0.75" tall Nixies and 1 special symbol Nix. Works too! I can't bare to take it apart to make just to make two

Re: [neonixie-l] What is this connector called?

For lower-speed use cases, i.e. < 50MHz, I solder these to a ribbon cable which is then terminated in an IDC connector. I intersperse GND and signal lines. I then have a similar connector (opposite gender) going to the logic analyser. Big plus is that I can disconnect a DUT easily, i.e. have

Re: [neonixie-l] What is this connector called?

I've seen 2 types of grabbers - Cheaper ones that are a simple 'J' shape to reach around a pin. They work fairly well with 0.1" pitch devices. I got a bunch of these with an HP Logic Analyzer. - Similar to the picture above, almost like a pair of arms that hug the pin. With

Hello friends, I am currently setting up a new way of photographing Nixie tubes which will hopefully result in better quality pictures. To that end, I am also considering using different connectors to the Nixie tube pins. I was thinking about these: P5003 10Pcs Mini IC Test Hook Clip Jumper

[neonixie-l] What soviet-era equipment used IN-18's ?

Please take this with a grain of salt as this is purely speculation. I believe they were intended to be used in airports, sporting events, and any place where a large number of people would be looking at them from a far. However, I think that very few of them ever saw much use, as most of the

Hi, I'm salvaging some tubes from an old (broken) Sharp calculator and there is this on the display board (unfortunately I couldn't de-solder it so it is a little beat up, though probably salvageable). I can't find out what it is, does anyone know?

finally got a power supply and am wondering what to run my IN-1 tubes at IIRC your supposed to use current to change the brightness right? i set the supply to 140v and am using 10K or 20K ohm resisters on the cathode and get 1.01-1.24ma at 10Kohm and 0.65-.083ma at 20Kohm what the target?
