Raspberry Pi Zero NPR One Radio

https://youtu.be/0OiZ5\_DXu78

UPDATE Added speaker holes to the bottom of the enclosure.

This project uses a Raspberry Pi Zero to make an NPR One radio using the NPR One API.

Capacitive touch controls printed in Conductive PLA from Proto-pasta. The Adafruit MPR121 capacitive touch sensor is connected to wires with bare conductive paint.

The Pi Zero connects to the NPR One API and streams audio via WiFi. The Adafruit MAX98357 connects over I2S to give the Raspberry Pi Zero analog audio out.
