IKEA’s flatpack furniture has long been popular among makers for its modular nature and low cost, making it ideal for whacky experiments and custom builds. [Claus] is one such person, and built a fun MP3 player for his kids out of a basic LACK shelf.
The music is handled by an NodeMCU ESP8266, working in concert with a VS1053 audio board. The VS1053 is a highly capable chip, capable of decoding a variety of raw and compressed audio formats as well as MIDI, but here it’s used to read SD cards and play MP3s. An RC522 is used to read RFID cards to trigger various tracks, allowing kids to choose a song by simply placing a tag on the shelf. A cheap PAM8302 amplifier and speaker are used to output the music. All the hardware is installed neatly inside the LACK shelf, an easy job thanks to the primarily cardboard construction.
RFID cards are more fun than we normally give them credit for, and we’ve seen a few builds along similar lines to this one. Video of [Claus’s] child rocking out after the break.
