  • alles

    A many speaker distributed music synthesizer using UDP multicast over WiFi

    • The Alles synthesizer is precisely this setup, but uses 5V to power the MAX98357A from a 3.7V battery via a 5V boost circuit. It's plenty loud with a 4ohm 3W speaker. There's pretty good schematics etc in the repo: https://github.com/bwhitman/alles/tree/main/pcbs
