ENGR 440 Plasma Speaker

We finally got plasma, and not only that but plasma that talks (in Binary Frequency Shift Keyed audio that is). The quick summary (as I am short on time during finals) our system takes user text and translates it into a BFSK audio file. This file is then transmitted through the plasma speaker and received via microphone, filtered with a dual PLL, then reconstructed into text and displayed on an LCD display. I will post details later but that is the gist of it.
