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.
