A Maker by the name of Arons recently decided to create a barebones MP3 player for his daughter based on the Hörbert.
Dubbed MBox, the device is capable of playing a wide range of audio formats, including MP3, MIDI, WAV and Ogg Vorbis. The platform is powered by an Arduino Uno (Atmel ATmega328) paired with a Freaduino MP3 music shield.
The MBox is capable of playing a wide range of audio formats, including MP3, MIDI, WAV and Ogg Vorbis. Additional components include a mono audio amp breakout, 2-10KΩ resistors, loudspeaker, keypad, 2KΩ potentiometer, on/off switch, USB power bank, wood and yes, even a piece of an old climbing rope.
Arons neatly placed all the components into a wood box, utilizing the old climbing rope as grab, with the USB port fitted in the back to easily charge the power bank.
“The MBox [supports] SD cards (FAT 16 or 32) and contains 12 directories starting from 0 to 12,” he explained in a project blog post. “Every button of the keypad is associated [with] a directory.” Meaning, each number plays from a different directory on the SD card.
Arons says his daughter is happy with the MBox and uses it quite frequently.
“I was really impressed to see how quickly she learned to select the track she wants to play,” he added.
