[Armilar] wanted to cheer up his friend who was going through a rough spot at the time — she really likes Dieselpunk, so he decided to improvise a Dieselpunk themed photo shoot for her. We’re assuming they had other costumes and props, but [Armilar] had this idea to make a nixie tube pendant for a while, he’d just have to expedite the build process to have it ready!
What he managed to whip up the day of the shoot looks amazing considering the time involved, if not just a little bit ill-advised. There may or may not be 200VAC running around his friend’s neck.
He’s using an electroluminescent driver rated for 5VDC to 100VAC, over-powered to 12VDC, resulting in about 200VAC, which is just enough to make the nixie glow a nice warm orange. In an effort to minimize the size of the pendant, he had to keep the battery and driver hanging off the back of the necklace.
