Celebrate Display Diversity for a Circuit Circus Clock

There’s a lot to be said for nice, tidy projects where everything lines up and looks pretty. Seeing straight lines and pleasing proportions speaks to our obsessive-compulsive tendencies, and tends to soothe the mind and calm the spirit. But disorder is not without its charm, and mixing it up a little from time to time, such as with this mixed-media digital clock, can be a good idea.

Now, we know what you’re thinking — yet another Nixie clock. True, but that’s only half the story — or more accurately, one-sixth. There’s but a single Nixie in [Fuselage]’s circus-punk themed clock, …read more

Driver Board Makes Nixie Projects Easier than Ever

We know, we know — yet another Nixie clock. But really, this one has a neat trick: an easy to use, feature packed driver for Nixies that makes good-looking projects a snap.

As cool as Nixies are — we’ll admit that to a certain degree, familiarity breeds contempt — they can be tricky to integrate. [dekuNukem] notes that aside from the high voltages, laying hands on vintage driver chips like the 7441 can be challenging and expensive. The problem was solved with about $3 worth of parts, including an STM32 microcontroller and some high-voltage transistors. The PCBs come in two …read more

ESP-Powered Nixie Clock Knows the Time

We see more than our fair share of nixie clocks here at Hackaday, and it’s nice to encounter one that packs some clever features. [VGC] designed his nixie tube clock to use minimal energy to operate: it needs only 5V via USB to work, and draws a mere 200 mA. Nixies require Soviet-approved 180v to trigger, so [VGC] used dynamic indication and a step-up voltage converter to run them, with a 74141 nixie decoder doing the heavy lifting.

The brains of the project is an ESP8266, which connects to his house’s WiFi automatically. The clock simply dials into an NTP …read more

High Vacuum with Mercury and Glassware

If you want to build your own vacuum tubes, whether amplifying, Nixie or cathode-ray, you’re going to need a vacuum. It’s in the name, after all. For a few thousand bucks, you can probably pick up a used turbo-molecular pump. But how did they make high vacuums back in the day? How did Edison evacuate his light bulbs?

Strangely enough, you could do worse than turn to YouTube for the answer: [Cody] demonstrates building a Sprengel vacuum pump (video embedded below). As tipster [BrightBlueJim] wrote us, this project has everything: high vacuum, home-made torch glassware, and large quantities of toxic …read more

Plus Size Watch with a Pair of Tiny Nixies

When you stuff a pair of Nixie tubes into a wristwatch the resulting timepiece looks a little like Flavor Flav’s necklace. Whether that’s a good thing or not depends on your taste and if you’re comfortable with the idea of wearing 200 volts on your wrist, of course.

As a build, though, [prototype_mechanic]’s watch is worth looking into. Sadly, details are sparse due to a computer issue that ate the original drawings and schematics, but we can glean a little from the Instructables post. The case is machined out of solid aluminum and sports a quartz glass crystal. The pair …read more

Sculptural Nixie Clock has Shockingly Exposed Design

Single tube Nixie clocks? Been there, seen that. A single tube Nixie clock with sculptural wiring that exposes dangerous voltages? Now that’s something you don’t see every day.

[Andrew Moser]’s clock is clearly a case of aesthetic by anesthetic — he built it after surgery while under the influence of painkillers. That may explain the questionable judgment, but we won’t argue with the look. The boost converter for the Nixie lives near the base of the bent wire frame, with the ATmega 328 and DS1307 RTC supported in the midsection by the leads of attached passive components and jumper wires. …read more
