Danger Wand: UVC germicidal light

Warning: UVC is the most dangerous kind of ultraviolet light. Do not expose your skin or eyes to UVC light for more than a few seconds at a time!

For this build you will need the mini UVC fluorescent tube and power supply/ballast from Ali Express. Such as this one: https://www.aliexpress.com/item/1005005261880760.html

Note: if you get the tube "without ozone" it will not be UVC germicidal, it will be a normal florescent tube putting out only normal light.

I replaced the JST connector with a DC jack to terminal block plug because I dislike JST connectors. This is optional: https://www.aliexpress.com/item/32982446328.html (use your favorite plug or anything you already have)

Shop around the related items for the cheapest one, because the fact that I linked these might mean the price goes up.

You will also need some power source: 3.7V-12V. I am just using one 18650 lithium cell, but you can do whatever works for you.
