Pi Radio

thingiverse

A cutting-edge 'retro' style web radio, built on Volumio with a Raspberry Pi Zero W at its core. Push-fit panels make it easy to add fascia, switch button holders, and more - just glue the Zero's bottom case to the enclosure, speaker mounts, and 16x02 LCD panel in place. Tapered screws secure the LCD and Pi to their cases. To take it to the next level, I also added an enclosure without a switch panel or volume knob for those who want to go headless with Volumio. **Gather these essential parts:** 1. Raspberry Pi Zero W 2. 3W Speakers (45mm x 2) - scavenged from old desktop speakers 3. PCM5102 I2C DAC or your preferred Phat DAC 4. PAM8403 Amp with Potentiometer/Volume Control 5. 16x02 LCD with I2C piggyback 6. 4 Tactile momentary switches (4 or 2 legs type) After some research, I got the GPIO button listener and LCD display working in tandem. This project is a blast to build, and it looks awesome on my workbench too! **Check out these useful setup guides:** 1.
