A 'Smart Boombox' with Open Source Hardware and Software
summary
A DIY boombox uses a Raspberry Pi 4 with a DAC HAT, Mycroft for a Mycroft local assistant wake‑word and intent parsing, and a 2.1 acoustic design with down‑firing sub and passive radiators built from Baltic birch plywood. CNC LongMill produces the cut panels, power comes from a 24 V 5 A supply (≈120 W), and total parts run roughly $400–425 for a model. The design boots Ubuntu, indexes local USB music, fills a room at moderate volumes, and ships as 14 build steps; Raspberry Pi shortages and clamp accidents are the main gotchas.
