As you might see, the semiconductor crisis is nowhere near to end, forcing us, tinkerers and developers to search for alternative hardware.
I’ve gained some previous experience porting zynthian to an Allwinner H3, which proved out to be a great success.
However… That solution is far from perfect, and that is because of unnecessary limitations(lcd interface, mainly, which takes valuable CPU power).
I was lately experiencing with a rather old tablet containing an Allwinner A31s(almost same stuff as H3, but targeted for mobile applications), and was able to get Armbian to run on that little puppy.
This light up a spark in my mind about the feasability of using old portable devices for building a Zynthian.
Well, to be fair, you got everything you need in there:
CPU power, a display which runs on a dedicated high-speed interface, built-in soundcard(with embedded speakers! ) battery and so on.
This would be the perfect candidate for a portable synthesizer. Just hook up a USB-OTG and a USB keyboard and you’re ready to rumble.
These might be just fantasy, but I generally love repurposing old devices and giving them a completely new life.
Thinking about that, the guys at PostmarketOS are doing a great job bringing linux to old phones. But they are using a lightweight distribution based on arch linux(IIRC), AND some drivers may be manufacturer blobs. Also, I don’t know about the portability of the packages used by zynthian from one OS to another (Armbian proved successful, so porting to that might be the logical approach).
I do own a Samsung Galaxy A3 2015 which is based on MSM8916 and it seems to have good mainline support
