Eric writes (and from the MAKE Flickr pool):

Someone at the Maker Faire challenged me to turn a working nixie tube into jewelry. Here’s a “glowing cross” steampunk-style pendant. It uses a CR2032 coin cell battery to run the high voltage power supply. It uses less power than an LED throwie.

I don’t know what’s better, this project or the fact that it was conceived at Maker Faire.

    I’d buy one if you decide to make them and sell them!

    are schematics for the power supply available? I see a transistor and some kind of coil in there…

    Nixie tube is fantastic…for a sleeker project, the same inverter could be used to power some miniature neon indicator bulbs. Maybe a cluster of three, glowing warm orange….

    180 volts around your neck! Hopefully you’ll wear some insulating material for clothes.

    A boost converter using a coin cell battery would probably have trouble sourcing enough current at 180V to do serious damage to the wearer in case of mishap. Hopefully….
