Parallax Propeller music player

Building MCU based music player is a good exercise for hobbyists today. This time take a look at propeller based MP3 player design. It has everything a decent player has – a regulated power supply (9V battery), buttons, audio amplifier, accelerometer input, LED and SD card reader to read songs out of flash card.

As project supposed to be finished in one day – this is pretty raw design with no intention to put it in to enclosure. Anyway it plays wav files as there is no mp3 encoder used. So be sure to pick large capacity SD card for mp3 to wav converted files. There were some intentions for future improvements where accelerometer would be used for basic controls. But for now – not bad for one day project.
