Go ahead and get your Blue Ball jokes out of the way right now.
Here’s a little something I threw together from scraps one day. It’s just a copper fitting soldered to a round copper disk with a coil of 6 gauge copper wire wrapped around it. A wooden base from the center of the Boiler Speakers front panel, a 1 watt UV LED, a Quartz ball, and VOILA!… a.. um… steampunk thing-a-ma-jiggy.
This is a cool little thing that you just plug in and sit on a shelf.. it glows with blacklight goodness, and that’s enough for me!
