A simple ESP8266 NodeMCU and VS1053 based internet radio receiver dedicated to my family. It is hardcoded to a single station. Just turn on and listen.

To avoid noise caused by the power supply and the jack connector creating a ground loop, solder a 47uF capacitor onto the PAM8403's VREF pin, and connect it to the jack connector's ground.
The volume control uses a 47k Ohm resistor from the 3.3V line, then a 10k Ohm resistor to the NodeMCU's ground.
