FINAL
23 September 2026 — where P1 stands
The enclosure concept remains 320 × 320 × 300 mm in 15 mm birch plywood. The current interface uses a 3.4-inch round display as a volume indicator, one rotary encoder and two buttons for AirPlay and Bluetooth.
The current computer is a Raspberry Pi 3A with a 64 GB card. Power, GPIO header and service parts are already part of the hardware workstream. Spotify Connect via librespot remains planned.
Why the old P0.2 files are archived
P0.2 used earlier assumptions for coaxial driver, display and computer hardware. Those files remain useful to understand the mechanical development, but they are not a manufacturing release for P1.
