In this project we'll build an MP3 Player based on the Feather M0 with a Music Maker wing. It plays a wide range of audio formats like such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM)! It also features a removable SD card for storage! Its portable and easy to power with the Feathers built in rechargeable circuit. The tiny size is perfect for installing inside small areas or as a wearable!

Parametric Design
The player design is based on Gordon Cole's Hearing Aid from the popular show Twin Peaks.
We thought it would be fun to model the design around this characteristic wearable but with a twist.
Instead of a hearing aid, we made an aid for hearing music. ha. Although a fun design we include the source file to easily modify the design to fit any theme! |

WearableYou can optionally print the included clip to make an awesome wearable mp3 player!
It can clip onto your front shirt pocket or on a belt clip. Easy to reach, soft tactile buttons let you quickly access the play, pause and next buttons.
The volume knob is easy to control with editable gain adjustments in the code. |
