Story

Have you ever wanted to hear the same notes played over and over again while headbanging to it? Have you ever wanted to move your head so rapidly like you are at metal concert but only ever listen to the same four notes? If you answered yes to one or both those questions, well do I have the answer for you. Introducing the head banger, the one of a kind sensory device that reads the movements of your head and plays a note while displaying a certain color determined by the movements of your head. The purpose of this device is to have the user experience sound caused by their own movement in a unique way.

1 / 10 • Step 1: Gather Materials

Each tilt plays one note and lights up one color so the user will have to chain tilts in order to achieve music. Any hat will do with this project but make sure it has the room needed for the CPX. Half way through the project, I had to switch to duct tape instead of office tape simply because the strength of the office tape was not enough to secure the CPX and battery so I highly encourage using it.
