Updateable Message Personal CD Player - Gen 4
Northwestern University, 2002 - $11,500
This E-Team received an E-Team grant ti develop the X-CD, a system that integrates wirelessly updated messages with recorded music. The X-CD is a portable CD player that receives messages broadcast over FM sub-carrier, stores them in memory, and plays them back before, during, or after any CD played, as appropriate. Listeners receive the X-CD broadcasts, consisting of story capsules, interviews, reviews, and advertisements automatically when they use a properly equipped personal music player. Magazines, television shows and others who advertise to young adult audiences buy air time from X-CD and provide the broadcasts. X-CD players, branded by these sponsors, are offered to magazine subscribers or prospective subscribers. The sponsors, magazines like Rolling Stone or Teen People, or TV shows like MTV, gain access to the young adult market.
The X-CD E-Team created three successful prototypes and used this grant to develop a fourth generation prototype. While the first three prototypes were PC-based, the fourth was built around an embedded microcontroller.
The X-CD E-Team consisted of three computer science undergraduates. They worked with an electrical engineering faculty member and the founder and president of SixtySeven Kilohertz, Inc.
