ArtsGala Sound-Reactive Dress | Planning

Wright State's annual ArtsGala scholarship fundraiser is always a fantastic event. Lots of hard work by students and staff goes into making it a fun and successful evening. This year I'm donating an e-textile workshop to the silent auction, and I thought it would be fun to promote it by adding an interactive light element to my dress.

After some time searching for a funky yet easily modifiable dress, I found this on eShakti:

Hardware-wise, I was inspired by Adafruit's sound-reactive mask project (Next!). Here's a snapshot of the general schematic:

I'd like to put more than 5 LED's on one pin, so I'll be solving for the LED capacity of the Adafruit Gemma (which I haven't used much yet) running on a 3.7v 500mAh lipo (Lithium Ion Polymer) battery. This involves math, so I'll put this part off as long as possible.

So here is a photo of the very beginning of the project, first few components; Adafruit AGC Electret Mic Amp, Gemma with a 3D printed sewable case (Proto BuildBar), lipo battery, Lilypad LED's, and of course a breadboard! Next: prototyping the circuit.
