CS194-05 (S'08): The Internet of Everyday Things
In Spring 2008, I helped teach an undergraduate EECS design studio course, called the Internet of Everyday Things. In addition to teaching core networking and embedded computing concepts, the goal was for students to build fun and useful IP-based applications on top of the same IPv6/6LoWPAN kernel developed for my research. The course was amazingly successful. In a matter of weeks, students built a Google Maps/Nordic Trac Cyber-Physical Mashup, Web-Enabled Coffee Pot, and a Smart Refrigerator.
