I made SideB, a retro cassette-style music player for the TrimUI Brick
I’ve been working on a small open-source project for the TrimUI Brick called SideB.
The idea was to turn the Brick into a tiny retro music player, something closer to a handheld cassette deck than a normal app. I use Spotify a lot, so the main mode is Spotify Connect: launch SideB on the Brick, pick “TrimUI Brick” from Spotify, and use the device as a small physical receiver with cover art, playback state, cassette-style UI, and hardware controls.
It also supports local MP3 playback and an on-device FAV LIST, so it can work as a small offline music player too.
SideB is open source on GitHub, and it’s already available in the NextUI Pak Store under Media. The latest release also adds a battery/status indicator and safer screen-off behavior.
I’d love feedback from other TrimUI Brick users:
- Does it launch cleanly on your setup?
- Does Spotify Connect show up reliably?
- Do the buttons feel natural for music playback?
- Does local MP3 import/playback work well for you?
- Is there anything in the UI that feels wrong on the actual screen?
This is a personal-use open-source project. SideB doesn’t intercept, decrypt, or record Spotify streams; Spotify Connect and local/offline playback are separate paths.
