[neonixie-l] Re: What type of tubing / valves are used in vacuum and de-gassing, gas population experiments?

The only gauge I can think of would be a standard "U" gauge (manometer), but that is only practical down to a few millibars with mercury. Maybe there are some exotic liquids with low vapor pressure that might work a bit lower, but I doubt anything exists that would get you into the micron

Re: [neonixie-l] Re: What type of tubing / valves are used in vacuum and de-gassing, gas population experiments?

I’ve read somewhere that people have had reasonable success in making Nixie tubes with just a dual stage rotary vane pump, so it may be worth giving that a shot before spending loads of money on a diffusion/turbomolecular pump, controller and pirrani/ionization gauges. Check out this website here: 

[neonixie-l] Re: What type of tubing / valves are used in vacuum and de-gassing, gas population experiments?

Actually there was something else I was wondering about. Is there such a thing as an accurate vacuum gauge which you can just drop into a chamber instead of connecting to the valve / air line of the pump? Conceivably it's something that has it's own sealed air container and would detect the

This may not apply to other tube types, but my 3 clocks built with 6 x B7971s were MUXd at about 2 kHz, and they all produced enough acoustic noise to be annoying in a quiet room, and RFI audible over the entire AM band that was detectable on my transistor radio to about 20 feet. The clock

[neonixie-l] Re: What will happen if current slightly below specification in long time?

The voltage across the tube starts high, while the tube impedance is high, before the gas discharge has been established. The current then rises relatively slowly, while the voltage drops at a proportional rate due to the anode resistor. Threeneuron has an excellent page on driving nixies

[neonixie-l] Re: What will happen if current slightly below specification in long time?

For the following reasons: 1. High voltage swing PWM, I am afraid it will cause EMI interference. 2. As far as I know, the impedance has a sharp change during the lighting moment. (As arc discharge?) PWM driving may mean more heat generation, more aging and wear? I'm not sure. 3. If you want

Out of curiosity, why doesn't PWM sound like a good idea? There isn't really an alternative, other than lowering the current, which you don't seem too fond of either. I'd say PWM is the easier method. Just choose a sufficiently high frequency to avoid noticeable flickering. Note that the

That's what I did: opaque black plexiglas for the sides and the ack, opaque white plexiglas for the top and bottom, and clear red for the front. It gives it a mid-20th century modern or Bauhaus look with the digits floating inside the box instead of a steam-punk look, and emphasizes its

Re: [neonixie-l] Re: What a find!

Yes Apex surplus in San Fernando I went through their stock. They have more than 25 more nixie devices left! Most of the prices are fair. I did see a lot voltmeters using the skinny little Burroughs 88xx series. They don’t have a useable website ... so you have to drive out there. Just don’t

Re: [neonixie-l] Re: What is this 6209 G from sharp calculator?

It has connections to each of the cathodes. There are twelve cathodes for these tubes (CD80-P), so twelve pins are connected each to a different cathode (that might be 11. There is one trace that is difficult to follow). That leaves 8 pins on the device itself. Each cathode on a tube is

[neonixie-l] Re: What voltage/current to run tubes at

See what voltage you need for the tube to strike in a dark room. If you run the tubes at too low current, you risk cathode poisoning. It won't appear immediately, but takes time. Weeks or months. What you'll eventually see is only partial illumination of the digits. Positive neon ions hit the

I worked (and am still working) on my Nixie tube thermostat for my heater. Though it will have 4 relays for controlling anything. I only have a heater (radiator), I am using a PID controller to regulate the temp. Cooling will just be a standard stupid algorithm, one tested by turning on and off a
