Knobby
An open-source hardware remote control for Spotify that helps you discover new music and control playback on any Spotify Connect device.
What is Knobby?
Knobby is an open-source hardware remote control for Spotify that enables users to discover new music and control playback on any Spotify Connect device. It features a single rotary knob interface to explore thousands of microgenre playlists, randomize music, and access personal libraries, solving the problem of musical boredom with a tactile, screen-free experience.
Spotify Premium users who want a dedicated, distraction-free remote for their smart speakers or home audio systems, as well as DIY electronics enthusiasts interested in building custom hardware projects.
Developers choose Knobby for its unique combination of music discovery features, open-source hardware design, and minimalist interface that encourages exploration beyond algorithmic playlists, offering a tangible alternative to app-based controls.

Pros & Cons
Pros
Accesses over 6,000 microgenre playlists from Every Noise at Once, far surpassing typical streaming service recommendations for niche exploration.
Single-knob design eliminates screen dependence, making it ideal for shared environments like parties or focused listening sessions.
Firmware is MIT-licensed and enclosure is 3D-printable, enabling community modifications and DIY builds with common ESP32 boards.
Directly manages playback on any Spotify Connect device, with features like random shuffle and fast library access for personal music.
Cons
Only works with Spotify Premium, locking out free-tier users or those on other services like YouTube Music or Tidal.
Requires sourcing specific parts (e.g., LilyGO board, Bourns encoder) and skills in soldering, which can be intimidating for non-hobbyists.
Optimal performance depends on always-on Spotify Connect devices; issues arise with Chromecast or when playback isn't pre-started, as noted in the README.
