The $35 Raspberry Pi is the low-end computing system that launched a thousand projects, including a beet-powered Beetbox and this Spotify-compatible cassette player. CNET writes that Matt Brailsford’s nostalgic masterpiece was inspired by the iRecorder, which is an iPhone speaker shaped like the old-fashioned tape machine. In an interview with CNET, Brailsford explains that the Raspberry Pi used in his device runs a version of MusicBox, and a custom module for identifying input and reading NFC tags.
