It runs on 4xAA batteries and right now has a handful of different modes, which you can cycle through with one button. The sweet thing is the microcontroller plugs into the computer with a micro USB port, so I can keep adding modes as I think of them (and as I sucker my significant other into helping me program them). All the electronics reside in a single pocket, leaving me with three large utili-pockets free to stuff with whatever I please!
Thank you to whoever recommended I use the Fabric Stik fabric glue (I think it was junglesmacks). I used an entire package on this to attach the LEDs, and when it turned out that the tulle was too ungainly to sew into the belt portion as I had originally planned. The only thing I need to figure out now is some kind of trim to cover up the unsightly glue and tulle lumps at the base of the skirt.
Here's what it looks like, lights off:
I need to get back to work on the LED vests I was planning, but I decided I want to order some FLAT LED strips (the lights I purchased stick out way too far). Any leads on flat, addressable RGB LED strips with about 30 lights per metre for a good price (i.e., less than $10 a metre), let me know! I'll go back and check the fur coat threads, as I know a few people used these.
