Wind Chimes (Arduino, Raspi, and Magnets!!)

Arduino Uno Talking to Raspi via Serial

I'm going to do a quick post on another project I'm working on.  This is not complete yet, but I'll share my progress to date.

Here's the concept:
I'm building a wind chime that does not actually chime, well, acoustically that is.  Instead, it will allow me to play any sound for a chime instead of a metal or wood clunking sound.  I will capture the "striking" of a "chime" (yes lots of quotes) using analog sensors on the Arduino, and then communicate a command to the Pi via a serial line. I am using the Arduino for it's analog pins and its ability to sample incredibly fast.  I'm using the Pi to play sounds simultaneously (Nope, there is no simultaneous audio shield for the Arduino).  Pi audio is a longer subject worth of its own post. But the audio you hear in the video below will not be the finished product.
