What is this?

My wife is a Montessori teacher, and didn't want screens to be a part of his life until 6 years old. I wanted him to be able to choose his own music and play it as much as he wanted. This jukebox lets him do that without screens.

He just holds the card with the picture of the song/album near the jukebox and it starts playing...

Magic!

Kit

This is still evolving, the last evolution was:

• Raspberry Pi 3 + Case / Power $50
• USB Mifare Card Reader $16
• SD Card $11
• USB Flash Drive $8
• Mifare RFID cards $40
• Card protector sleeves $7
• Mini Remote Control $13
• Mini USB Cables $9

Installation

Install Raspbian on the Pi

Install NOOBS (https://www.raspberrypi.org/documentation/installation/noobs.md)

Preparing your music

The structure for the USB Flash Drive is:

music/
    1-my song.mp3
    2-my other song.mp3
    3-my album/
        first album song.mp3
        second album song.mp3
sounds/
    i_am_listening.mp3
    repeating_on.mp3
    repeating_off.mp3
cards.txt

You can copy the sounds directory from this repository. And the cards.txt file will get generated for you.

You have to populate with music directory. All that's important is that every file or directory starts with a distinct number then dash.

Mount the USB Flash Drive

create the mount

cd /mnt
sudo mkdir bigdaddy
sudo mount -o uid=pi,gid=pi /dev/sda1 /mnt/bigdaddy
sudo vi /etc/fstab

    add this line:
    /dev/sda1 /mnt/bigdaddy vfat uid=pi,gid=pi,umask=0022,sync,auto,nosuid,rw,nouser 0 0

Try it out, you should see everything on the flash drive under /mnt/bigdaddy
