Readers might be entertained by a Nixie-tube artwork I made many years ago, using 4 "giant" Nixie tubes--reputed to have come from the NY Stock Exchange when they upgraded. I attach a photo; the piece is about 4 1/2 feet tall. I programmed it to deliver 512, 4-letter words arranged into droll and mildly insulting sentences/paragraphs, all decent. It sold immediately from a gallery, to a realtor who put it in her office for the entertainment of her customers. I wish I still owned it...
This isn't playing with Nixies. Buying Nixies, wiring tube sockets and getting a bite from the high voltage is playing with Nixies.
While interesting that this project outputs an analogue voltage which sometimes represents the correct time, not actually using the Nixie tubes directly kind of takes the fun out of it. You can use any dvm for this and that would be interesting in and of itself.
But what's the point if you don't risk getting a mild shock from playing with the circuit? And if you don't actually use nixies how are you going to learn anything?
Building a display with nixies is not a big deal, just some high volt switching transistors like a mpsa 42 or 92 tied to the output of the driver chip, whether it's a clock or voltmeter or a random number generator.
I've worked with vacuum tubes my entire life and there is a lot more fun to be had lighting them up and making them do something useful or even unnecessarily useful.
You haven't lived unless you've been bitten by 30KV off a color CRT.
The final showdown is under way in our first-ever Gadget Freak of the Year contest. Who will win an all-expenses-paid trip to the Pacific Design & Manufacturing Show? It's up to you, dear readers, to tell us.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
