Anyone looking for a DIY project to fill a little time over the next couple of weekends might be interested in this very unique plywood boombox which plays music from SD cards. The Boombox was created by an MIT student and has been laser cut from plywood and equipped with a set of capacitive controls.
The Boombox’s main control board includes at Atmega328, an SD card socket, an mp3 decoder + D/A chip, and a level shifter to convert from 5V to the 3.3V required for the SD card and mp3 decoder. The complete system can be constructed for around $100.
If you fancy building your very own Matt Keeter, has put together instruction on how to build one from scratch over on his website.
“The main board’s firmware was written in the Arduino language to take advantage of the SD library. Some of the code is based on the Sparkfun MP3 shield sample code. The boombox has a set of five capacitive buttons on the front. Each of these buttons is above a copper pad, which is in turn wired into the input board.”
