nixie tubes

I don't think it was just price that kept them out of clocks.  They got pretty cheap on the surplus market back in the 70s and I built a clock with them.  When left on continuously, they blacken.  I think it took a couple of years:  they were still lit inside but you could barely read them.  All of the ones I ever saw were glorified neon lamps and had that orange-red neon color.

Plus, we pay $500 to our Gadget Freaks. Feel free to spread the word.

There is a very active Google group devoted to Nixie fans. It's a bit of a cult industry, lots of geeks putting together nixie projects, complete clocks, kits for sale, etc. (I'm one of them). The tubes themselves are getting a bit pricey, at least for large ones, but are still available in pretty good quantities. The tubes were still in production in the old Soviet Union right into the 80's, maybe later.

There has been discussion of nixies spotted in movies. There were even a few pinball machines that used nixies as the score display. Lots of test equipment, other industrial applications, but interestingly, they were rarely ever used as clock displays in their heyday, as they were too expensive for consumer applications.

If you're interested at all, join the Google "neonixie" group.

Thanks, rajackson. I guess that explains the color change. Not being a Nixie fan or user, I wouldn't know the difference between the two, but now I'm curious about the appearance of such items in movies. I bet someone somewhere has made (a) list(s).

The indicators on James Bond Goldfinger are *NOT* NIXIE tubes they are a simmilar vintage display though, The displays in question are side illuminated displays that use a set of ten incandecent bulbs to light the edge of a plexiglass sheet. The digits them selves are made up of dots drilled into the sheet. For a movie with NIXIE tubes check out the display counters in PIXAR's Monster Inc.

Try being bit by a 50kV Pulse Transformer in the fifth grade haha, that's what got me really going... then two more times in the next five seconds!

 

I love my nixies, but for this project I didn't want to ruin the meter so I didn't re-wire the nixies themselves (yes, I know it is a must for me but I am also a college student on a ramen type budget, I have to select which equipment I ruin wisely). I'm going from the ground up with some NOS parts from Russia for that.

P.S: It says James in the article because that's how I sign my name on a lot of stuff, Jimmy for conversation though.

Well, I *am* old enough to have seen Goldfinger contemporaneously--just barely. I remember that scene well, and I think it's amazing that anyone could identify the Nixies as Nixies during such a tense situation. 

Any idea why the color change?

Old analog tech acolytes may recall the appearance of Nixie tubes in the early James Bond film "Goldfinger," where Sean Connery is handcuffed to a bomb at the end of the movie. The bomb has a Nixie tubes showing the timer counting down to detonation. Interestingly, I don't think they were red, which was the more common color, but rather white, which is why they kind of stood out at the time. (I should note that I'm not that old; I did NOT see Goldfinger contemporaneously.)

My husband serendipitously mentioned nixie tubes the other day, so I couldn't resist sharing his experiences with them

His dad was a Heathkit hobbyist back in the early seventies who also made a few digital clocks, a few of them sporting these very tubes. Hie remembers his dad designing the board layout from circuits pre-designed by an engineer friend, and then etching the patterns in an acid bath in the kitchen. Soon, my husband was drafted by Dad to solder the components onto the boards. Eventually, the move was made over to LEDs for reasons of power efficiency, but he says he still missed that yellow glow.

Thanks for posting the art, Ken. That's a fine use of the Nixie tube. Anybody else out there with cool uses of the Nixie tube? The art use seems to have worked very well.
