San Francisco's Mission District is now under 24/7 musical surveillance
Briefly

The Bop Spotter project combines a cardioid microphone, an old Android phone, and solar power to create a live music playlist from San Francisco's Mission District.
Walz's ingenious system records the street music, identifying songs through Shazam, resulting in a dynamic playlist reflecting the local culture and community.
The most challenging aspect was finding the perfect pole for the microphone; Walz spent hours searching for a chaotic location with Wi-Fi and sunlight.
He believes the technology, which organizes audio into 15-second clips for song identification, feels like 'magic' as it captures the ambiance of the neighborhood.
