This may be a controversial statement, but Nixie tubes have become a little passé in our community. Along comes another clock project, and oh look! It’s got Nixie tubes instead of 7-segment displays or an LCD. There was a time when this rediscovered archaic component was cool, but face it folks, it’s been done to death. Or has it?
So given a disaffection with the ubiquity of Nixies you might think that no Nixie project could rekindle that excitement. That might have been true, until the videos below the break came our way. [Tobias Bartusch] has made his own Nixie tube, and instead of numerals it contains a 3D model of [Darth Vader], complete with moving light saber. Suddenly the world of Nixies is interesting again.
The first video below the break shows us the tube in action. We see [Vader] from all angles, and his light saber. Below that is the second video which is a detailed story of the build. Be warned though, this is one that’s rather long.
The model is made by carefully shaping and spot welding Kanthal wire into the sculpture, a process during which (as [Tobias] says) you need to think like neon plasma. It is then encased in a cage-like structure which forms its other electrode. He takes us through the process of creating the glass envelope, in which the wire assembly is placed. The result is a slightly wireframe but very recognisable [Vader], and a unique tube.

Imagine that your wife likes Darth Vader and wants help making important life choices. (Who doesn’t?) [bithead942] solves both problems in one project by gutting a Lego clock and making a talking animatronic Darth Vader 8-Ball-style oracle. Now his wife can simply press Darth’s head and her decision-making is handled by the Dark Side of the Force.
You can see the result in the video below the break.
The internals consist mainly of an Arduino Nano, a WTV020SD WAV playback chip, and some swanky servos. [bithead942] took a Dremel to the existing clock interior and found a way to make it all fit. The cloak helped, and the speaker was a good fit for the previous clock’s display.
Then he used IMDB and combed through the Star Wars movies to find Darth Vader quotes that kinda sound like the 8-Ball’s answers. As [bithead942] mentions Darth Vader doesn’t really dwell much on the positive, so finding instances where he says “yes” was hard work. This is in contrast to the original 8 Ball which has a brighter outlook than a cheerleader on Prozac, but there’s a reason they call it the Dark Side.
We really like the way the waist and arm servos work together to bring Darth to life. The added oak base with pull-out instruction card not only makes Darth look fancy, but prevents him from falling over when he leans forward to talk. All in all, a really nice build and well written-up with difficulties and their solutions.
