Clock radios are everyday hated devices that designers seem to ignore, judging by how little their features and user interfaces have changed. This project adds a new capability, letting would-be sleepyheads enjoy a human-machine interaction of a different sort. Don’t worry, we’re not going to connect your clock to an MP3 player and play mellow New Age sounds. We’re going to shoot the alarm off. With a gun. Wake-up time is now payback time.

We’ll base the project around a digital clock radio and a light gun for gaming; huge selections of both of these are available inexpensively second-hand, with many beautiful and well designed examples. To enable our FPSI (First Person Shooter Interface), we’ll outfit the gun with five tilt sensors, arranged at different angles on a small circuit board. A cable tethers the gun to the clock and carries your tilt and trigger signals to the clock’s time and alarm control button contacts.
