Mini Record Player is Actually a Spotify Streaming Device

A small document participant has stepped into the twenty first century, collaborating with Spotify in an surprising manner. The mastermind behind this mission, AKZ Dev, has managed to breathe contemporary life right into a novelty coaster set constructed like a bit of turntable, combining old-school magnificence with trendy audio streaming. They’re designed to seem like actual information, full with printed labels and all.

AKZ Dev managed to show these coasters into an actual document participant by putting in a Raspberry Pi Zero 2 W, which serves because the operation’s primary processing unit, monitoring what’s occurring and managing the Spotify connection. Then they hid an RC522 RFID reader beneath the dish, which simply reads the coasters. Every coaster receives an RFID tag on the again. When somebody places a document on the turntable, the reader takes up the tag’s distinctive ID, which corresponds to a selected piece of music on Spotify, akin to a full album, a playlist, an artist’s whole again catalogue, or only one single observe.

You may transfer the tonearm round by hand, similar to on a normal participant. There’s a small magnet hooked up to the arm, and a Corridor impact sensor (the A3144 kind) is shut. When the arm swings over the document, the sensor registers the magnet’s location. That instructs the Pi to start work, and the true playback begins with a stepper motor (28BYJ-48) related through a ULN2003 driver board. The motor gently spins the platter, offering the visible sign of a document shifting round. The music then begins to stream by means of whichever gadget is chosen on the account, which is usually an Echo Present with album artwork and observe info displayed on its display screen.

The ultimate piece of the puzzle is the software program, written in Python by AKZ Dev and accessible on GitHub underneath the RFID-Record-Player project. To get began, merely flash the Raspberry Pi OS, set up all the required dependencies, create a Spotify developer app to achieve API entry, and map all RFID IDs to Spotify URIs. Merely scan the tag on the coaster as soon as to assign it, after which save the pairings in a easy JSON file. After that, the system runs by itself.

Placing all the components collectively wanted some customized work, however the finish product is a 3D-printed enclosure created in FreeCAD and produced on an Elegoo Saturn. The enclosure options satisfactory air flow, a speaker grille space for many who select so as to add one, and even coaster stand helps. You drill some holes for the platter shaft, tidy up the cables, and conceal all the elements for a neat look. Previous to that, AKZ Dev performed intensive prototyping on a breadboard, experimenting with numerous tweaks alongside the street.

Whenever you raise the tonearm, it stops the music, simply as dropping the needle used to start out it. The platter merely stops abruptly, creating a definite on-off sense with none complicated screens or buttons in the way in which. When you have different Spotify units related to the identical account, they are going to fortunately choose up the stream, permitting the music to be performed by means of a greater speaker whereas the little participant handles the technical parts.
