Sami Pietikäinen has published a new Raspberry Pi project providing details on how you can create your very own Raspberry Pi Zero in car audio system which supports live streaming. The project uses a Raspberry Pi Zero fitted with a pHAT DAC (Digital to Audio Converter).
“My car comes with a built-in Bluetooth hands-free but unfortunately it does not support audio streaming. Luckily there is an AUX input available which uses a regular 3,5 mm jack. Perfect opportunity for a DIY project. I built the Bluetooth DAC using Raspberry Pi Zero W and a DAC hat. This post depicts the details of this project.
For the software, I did the first iteration using Raspbian, and it was indeed fairly simple to get the device working. However, I wanted to see if it would be possible to create a small stripped down image just for this purpose. For this, I used Yocto. Both approaches are described below.
If you just want to get things working without the project details, you can skip directly to the end and grab a prebuilt ready-to-flash image with the Bluetooth DAC functionality.”
