Nixie Steampunk Pendant

Newer Older

Someone at the Maker Faire challenged me to turn a working nixie tube into jewelry.

Here's a "glowing cross" pendant. It uses a CR2032 coin cell battery to run the high voltage power supply. It uses less power than an LED throwie.

    I would totally buy one, it's gorgeous. :)

    It is a beautiful piece of Steampunk art. Please share the DC/DC converter you've created to power it.

    I would though have some concerns about having that many volts going around my neck :P

    will you publish the circuit? also, whats to stop someone getting a jolt from the supply if they (for eg) get caught in the rain? no matter - its a gorgeous piece of work, and big credit for making it! :)

    you beat me too it ;) fantastic, and i really like how you mounted the driver :) beautiful :)

    Nice work!

    Very nice! I too would like to see the circuit, is it a regulated/switching buck boost?

    I don't recommend wearing it out in the rain. heh

    I'll draw up the circuit at some point. It's based on a Royer oscillator with a custom wound toroidal transformer.

    And yes, you probably don't want to wear it in the rain. I was originally going to seal the circuit board, but it looks so much cooler when you can see all the colorful components.

    People with pacemakers should avoid wearing it also.

    Me want! So awesome! Can the tube display different characters? Could you make it switch around randomly or something?

    Try potting the board in clear epoxy/resin/potting compound. It'll seal everything away but keep it all visible.

    i have lots of excess nixiness from building a clock...
    please post the schem/diagram, ive been dying to make something like this for a while but have been lame about the research :(

    Hi, I'm an admin for a group called Steampunk Gear, and we'd love to have this added to the group!

    hey --AP--,
    clear epoxy/resin/potting compound would probably create a lot of heat, and would melt the innards, thats what they are doing to some of the new flash drives, and there have been a ton of problems with melt/frying everything

    Great idea though, maybe a tiny circuit to control some scrolling text would be cool!!! Just a thought!!

    Dude! You should do that with a Magic Eye tube and a volume meter ;)

    That looks just amazing!

    Wow, the high voltage wire as the lanyard just tops it off.

    Perhaps a Joule Thief circuit would work as a step-up converter. Would love to see your circuit.
