On a dark and stormy night…
No wait! While bored and cruising Ebay one night, I impulse bought a 7" doubledin car stereo for $10.00. Not really knowing what I wanted to do with it, I had an epiphany to make it into an internet streaming infotainment device.
I have a few RPI’s lying around so I thought that the PI zero W should fit the bill nicely. Since the stereo is coming from China, I thought I would start putting the zero through it paces and see what it can do and what software/hardware combination I should use.
After installing a full PI install on the zero, I knew it would not do. It was sluggish with all the over head of the OS. I went through a lot of OS distributions trying to find a stripped down music/video OS for the zero that I liked. Most were meant for headless streaming and I wanted one with an interactive interface. I settled for LibreELEC. https://libreelec.tv/
With the OS settled, I now need to decide on the audio hardware to use with zero. I purchased a few audio DACs and have a few USB audio adapters that are RPI compliant.
The video input for the car stereo is a composite input. The zero actually has the ability to output composite video but has to be software enabled. I need to see if it will be usable or try an HDMI to composite adapter instead. All yet to be seen.(Oh! A pun!)
A quick test and it does what it is suppose to do. I might try it with a full blown RPI and see if it is more responsive or just live with the slower cheaper option.
I will update this thread as I continue to play with the combination of hardware and software.
