The following is adapted from an Instructable I wrote, with a few added photos here.
The Party Animal dancing speaker is a hilarious but awful product. For this project, I’m going to show you how to make it twice as funny and half as crappy by integrating a music player, connecting it to a real speaker and rewiring it for push-button play. I have mine dancing to Too $hort, but you can have yours dance to whatever you want.
What is this?
In this project I’m going to show you how to turn a inexpensive Raspberry Pi computer into a home for your MP3 music collection that you can browse and control from your phone or computer. This same setup can weave together online music services like Spotify and Google Music, as well as internet radio, and also act as an Airplay or DLNA receiver for streaming music from other devices.
