Sparking Musical Joy at Home With Magnetic Stripe Swipe Cards and...
summary
Raspberry Pi runs Pi Music Box to play Spotify URIs triggered by tactile magnetic stripe swipe cards, using a USB card reader that only reliably returns numeric tracks so each card encodes a three-digit padded code written to all tracks. Playback is driven by a tiny 5-line Bash script expanded with comments into 27 lines total, hits an octal bug at card eight, and uses 999 stop card as a pause control. Assembly includes stickers, a stacked box enclosure, and working headless autostart.
