This 5.6mm thick music player is made out of bamboo. It uses an ATTiny 85v, based on Elm Chan's design with some modifications. The player has a 100mah lipo battery that is charged externally via two pins. The microSD card is removable allowing easy uploading of songs. A momentary button sits underneath the bamboo; Once the user compresses the bottom portion of the player, it triggers the button and skips to the next song.
