• Kid cartridge story box v2

  goguelnikov • 01/16/2024 at 23:14 • 0 comments

  After a lot of work, I finished version 2 of the story box. Same cartridge system, same buttons, but I added a screen to navigate through the songs. 
  

  I used:

  An ESP32

  A TFT screen

  A MP3 player

  A USB interface

  A battery charging Module

  The ESP32 reads files on the USB stick when inserted, displays an image located on the drive.

  I also added + / - volume buttons that where missing on V1

  For a first version, I used a easily available MP3 playerboard:

  • MP3 Player: https://fr.aliexpress.com/item/1005002420437473.html
  • this is so cheap and working so well, it'is incredible...

  This board is connecte to a power bank:

  • 18650 power bank: https://fr.aliexpress.com/item/32969695165.html

  and a small 2x3W 5V amplifier:

  • Amplifier: https://fr.aliexpress.com/item/1005004226201772.html

  The Amplifier board is connected to 2 loud speakers (2 because stereo is COOOOL):

  • loud speakers: https://fr.aliexpress.com/item/1005004832493500.html

  and some nice buttons: 

  • buttons: https://fr.aliexpress.com/item/1005001683893211.html

  The wiring diagram is straight forward:

  The MP3 player is connected to the power bank. The sound output of the MP3 player is connected to the input of the amplifier. The USB plug / buttons are deported to the faces of the box, also the USB-C plug to recharge the box.

  And I printed :

  • a nice box designed in Fusion 360
  • a cartridge reader slot
  • some cartridges containing a USB stick

  in addition, to connect the USB cartridges to a computer or to a CD / external MP3 palyer accepting USB sticks, I designed slot with the USB extension cord.
