How do I convert a USB Plasma Sphere to battery power? Answered
I'm trying to make a "tesla cane" (just a cane topped off with a working plasma sphere) for my cousin's steampunk-themed wedding. I already have a USB Plasma ball (Model is here: http://www.thinkgeek.com/geektoys/science/964e/?), and I'd like to make it run off battery power. I'm good at soldering and dealing with small wires, but I've never measured voltage or anything like that. Advice? Has anyone attempted a project like this before? It seems like there are tons of "convert batteries to USB" tutorials but not many of the reverse. :)
Thanks in advance!
