Raspberry Pi enthusiasts that are looking for an electronics project to keep them busy this weekend might be interested in a new Raspberry Pi Zero powered AirPlay Speaker that has been created by Frederick Vandenbosch.
Check out the video below to learn more about the DIY project and how the small speaker system was created using a Wi-Fi dongle together with the new pocket sized Pi Zero mini PC, a pHAT DAC together with a few other components.
A new project to build around the Raspberry Pi Zero, I came across the pHAT DAC from Pimoroni. This little add-on board adds audio playback capabilities to the Pi Zero. Because the pHAT uses the GPIO pins, the USB OTG port remains available for a wifi dongle. Perfect for a small wireless speaker project!
The Raspberry Pi Zero is obviously the brains of the project and will run the Shairport software to wirelessly stream music to. The pHAT DAC is a neat little add-on board adding audio to the Raspberry Pi. It has a jack output, and the possibility to add RCA connectors to it. The fact that the RCA connectors are not presoldered is a bonus, as it exposes the audio lines and keeps a low profile. A small mono amplifier from Adafruit then takes the audio from the pHAT and amplifies it (what else?), playing audio from the speaker. A wifi dongle connected via the USB OTG port provides wireless network connectivity for streaming.The project is fairly simple and requires following components:
– Raspberry Pi Zero
– pHAT DAC
– Mono 2.5W Class D Amplifier
– WiPi wifi dongle
– Two 100 ohms resistors
– Speaker (4-8 ohms)
