:wall: I am currently looking into making a device that will: Connect to and read the contents of a usb flash drive, Navigate the contents of the flash drive via buttons, Display the current file via digital readout, Play the files, (mp3's and possibly other audio formats, if this is simple) in sequential and random order; Read a playlist (m3u and/or pls) and play the songs in the playlist order; Amplify the files for headphone output, This device must be small enough to fit inside either: A used cigarette pack, An Altoids pack; something else of that relative size. And it must run off of a 9 volt battery. Anyone with any resources to any circuit diagrams, or cheap supplies for this project, please post, and thank you. :yeah:
