erco's MP3 Player

My pal, erco (Eric Ostendorff, a.k.a. Mr. Roboto, from Servo Magazine) does it again. Cheap fun project. Eric says, "DIY this quick self-contained DIY MP3+speaker module for $4 plus your micro SD card. Search Ebay for a $3 Catalex YX5300 UART Serial MP3 Music Player Module and grab a Dollar Tree amplified speaker. For file format & serial commands, see http://geekmatic.in.ua/pdf/Catalex_MP... and numerous sites like http://www.amazingtips247.co.uk/2015/..."

and with a BASIC Stamp... Catalex MP3 BS2 Demo (with code!)
