At the heart of this project is the Radio Shack 9V Recording Module. This device records and plays back up to 20 seconds of sound. In this project I show how to modify it to make it motion sensitive.
Shake-Activated Present Prank
This is a project to play a prank on those people who insist on shaking their presents. It is a motion-sensitive box that plays pre-recorded sounds when the present is shaken.
