What’s the worst thing about winter? If you’re as indoorsy as we are, then static electricity is probably pretty high on the list. It can ruin your chips, true, but you always wear a wrist ground strap when you handle those, right? But away from the bench, every doorknob and light switch is lying in wait, ready to shock you. If you had an anti-static ring like [LaPuge], you could be watching a tiny neon bulb light up instead of the air between your poor finger and the discharge point.
The ring itself is printed in TPU 95A filament for comfort and flexibility. There isn’t a whole lot to the circuit, just a neon bulb, a 1MΩ resistor, and some copper tape, but this piece of functional jewelry has the potential to spark up plenty of charged conversations. Zap your way past the break to see it light up against a door handle.
If you want to light up neon bulbs all year long, build a field of them and wave them near your Tesla coil!

The Weatherclock is more than just a clock sporting Nixie tubes and neon lamps. There is even more to it than the wonderful workmanship and the big, beautiful pictures in the build log. [Bradley]’s Weatherclock is not only internet-connected, it automatically looks up local weather and sets the backlights of the numbers to reflect current weather conditions. For example, green for roughly room temperature, blue for cold, red for warm, flashing blue for rain, flashing white for lightning, scrolling white for fog and ice, and so on.
The enclosure is custom-made and the sockets for the tubes are seated in a laser-cut plastic frame. While seating the sockets, [Bradley] noticed that an Adafruit Neopixel RGB LED breakout board fit perfectly between the tube leads. By seating one Neopixel behind each Nixie indicator, each number could have a programmable backlight that just happened to look fabulous.
With an Electric Imp board used for WiFi the capabilities of the Weatherclock were rounded out on the inside. On the outside, a custom enclosure ties it all together. [Bradley] says his family had gotten so used to having the Weatherclock show them the outside conditions that they really missed it when it was down for maintenance or work – which shouldn’t happen much anymore as the project is pretty much complete.
It’s interesting to see new features in Nixie clocks. Nixie tubes have such enduring appeal that using them alone has its own charm, and at least one dedicated craftsman actually makes new ones from scratch.
Based on his username, [Horatius.Steam], it’s not a surprise that he calls this project a “SteamPunk” style binary clock. But we think using neon glow lamps in this binary clock is more of mid-century modern proposition. Either way, the finished look is sure to make it a conversation piece for your home.
He doesn’t give all that much information on the bulbs themselves. They seem to be neon glow lamps along the lines of a Nixie tubes. It sounds like they just need mains power (based on the image annotations for the relay board). The high voltage is switched by that collection of solid state relays. The controller board includes a DCF radio whose antennae is seen just below the controller. This picks up an atomic clock signal from Frankfurt, Germany. We think it’s a nice touch that he included a mechanical relay to simulate a ticking sound. That and the bulbs themselves can be turned off using the two switches in the base of the clock.
This seems like a good time to direct your attention to an artistic take on a Nixie clock.
Quick quiz, what came before transistors? Why vacuum tubes of course. If this clock doesn’t make you thankful for the luxury of integrated circuits, nothing will.
We had never heard of using Neon Lamps as logic circuits, and they definitely produce a much cooler effect when counting.
And finally, we’re just suckers for a good Nixie Clock. The scope clock is also pretty interesting.
