The goal of this project was to build a professional-grade home speaker system that leverages IoT technologies to provide audio to different areas of the house. For our project we have built a unit that will receive music streams from multiple devices and output them to the appropriate series of speakers.

We have constructed a musical instrument that relies solely on analog electronics and an interesting EM phenomenon. We've breadboarded a circuit based on a guide we found online, and have put it on a Printed Circuit Board (PCB).
