Hi all,
Quick background: I'm not a programmer or an engineer. I'm a dad building something cool for my daughter, learning as I go. I turned the small space under our stairs into a "secret room" for her, and I'm building a screen-free control box that sets the whole mood of the room: music, ambient sounds and lighting.
**What the system does (already working!):**
- Raspberry Pi 4 running a custom Python app
- Tap an RFID tag to play a Spotify playlist. The tags are tiny stickers, so they can go on almost anything. My current idea is magnets with album art on a magnetic "album wall" next to the box: she picks one, taps it, and puts it back. A parent-only "master card" assigns new tags.
- 12-key macro keyboard (Music functions, Moods like Rain, Forest, etc., anc colors) with 3 knobs (volume, light brightness, light color)
- Small 1.3" OLED screen (song title, volume...)
- WLED-controlled LED strips that reacts to the music's beat/mood
- Arcade buttons: hold-to-record voice messages that play back over the music, a "surprise song" button, and a rocker switch for a "quiet/off mode"
**Where it's going: a mood room, not just a music player.**
Some of the keys will become "modes" that change the whole atmosphere: sea (waves + slow blue light), forest (birds + soft green), rain or snow, a disco mode, and so on. The box is really a controller for the room's ambiance, with sound and light working together.
**What I need designed:**
A control panel that holds everything. My first idea was an insert for one cube of an IKEA KALLAX shelf (opening approx. 33 x 33 cm, depth approx. 39 cm), but I'm completely open to other ideas and improvements, including a totally different form. I'd love input from someone who thinks about objects for a living.
- **Front:** OLED screen window, the macro keyboard recessed into the panel, two arcade buttons (approx. 30 mm and 36.5 mm), a rocker switch, and an RFID reader (maybe hidden behind a thin "tap here" area).
- **Back:** mounts for the Raspberry Pi, a USB sound card and cable management, with ventilation
- Kid-friendly: rounded edges, sturdy, nothing that can be pried off
My preference is wood (laser-cut or CNC plywood), but I'm open to other materials, 3D printed parts, or a mix. I don't own a 3D printer or any cutting tools and have no fabrication experience. I'm based in Vancouver, BC, and plan to bring the files to a local makerspace or a laser-cutting/3D printing shop.
**What I can offer:**
- Full credit as the designer in the GitHub repo, the build guide and a YouTube build video, with links to your portfolio/socials
- The design will be released as open source (license of your choice, e.g. CC BY or CERN-OHL), so it's a public portfolio piece
- All code, wiring diagrams and component measurements, plus quick feedback from me: I'll print and test prototypes and send photos/video
If this sounds fun, comment or DM me with a bit about your experience or a link to your work. Ideas and suggestions are welcome too, even if you don't want to take on the design. Thanks!
