The latest creation in the never-ending collection of “____ Hero” instruments is this Raspi-infused pan flute, built by [Sven Andersson] and his team at the 2013 WOW Hackathon. The flute itself consists of varying lengths of bamboo from a local flower shop, cut short enough to be hand-held while still hiding the Pi from the front side. In the spirit of other ‘Hero’ instruments, the pan flute has no real musical functionality. Each pipe houses what appears to be an electret microphone breakout board, which they kept in place by sealing off the end of the pipe with glue.
The sensors connect to the GPIO connector on the Raspi, which communicates to a local TCP/IP server the team ran as a controller hub. The game is also their original creation, written entirely in LUA. They turned to Spotify to find suitable material for the player to experience, creating playlists with actual pan flute songs and using the libspotify SDK to access the music. You can see the end result of the project in a short demo video below.
