If anyone is searching for a cheaper parallax propeller board.  When I last checked,  I think I saw that Adafruit sells them for less than parallax does(lol).

This project is not limited to only using the propeller board, others can most definitely use Arduino with Adafruits open source led driver code.

The vibration motors should be bought in bulk so they cost less.  I bought mine off of ebay.

The neoprene sports vest was also bought from ebay.
