Greg is Chillin' With 50 Cent on His Tricked-Out Keyboard

For Greg Ruhlander's complete instructions on how to build your own computer keyboard with integrated am/fm radio, click here .

Unable to function without his trusty portable am/fm radio at his side-especially while working-Greg hit upon the idea of integrating it directly into his computer's keyboard. The big plus is no batteries required since the keyboard powers the radio. Taking a standard keyboard and small, portable radio, he designed a simple voltage reduction circuit to step down the keyboard's 5V to 3V, and there you have it: a convenient combination of two items or a boombox for geeks.
