Step 1: Parts
EL wire (I only used blue and white because that's what I had on hand, if I was building this from scratch I probably would use a bunc of different colors) (A good source for high-end wire is elwirepros.com, but eBay has some fairly good lengths of EL wire with free drivers super cheaply)
EL wire driver (make sure it's rated for the length of the strand)
Two 9V batteries
12V voltage regulator
Assorted soldering supplies, wire, heat-shrink tubing, etc.
