I would like to build a music player / device for an older person, not tech savvy user.
I have the MP3s on my linux desktop/laptop, but not all the metadata and cover art.
I’ve worked with RPi before, jailbreaking iPhones and roku. So I have some limited experience with small devices.
I’m wondering if I could obtain some kind of old/used android phone, remove all the apps so the home screen is completely empty, transfer via USB or ssh/scp the MP3 files (and metadata + cover art), then have some kind of music player app which would be the only app on the phone/device.
Then shutdown any wifi or internet connectivity, but still allow bluetooth to pair with an external speaker.
This is exactly what I did. I used an older Moto and uninstalled or disabled everything I didn’t want and only used BlackPlayer EX. It also has halfway decent external speakers so I can just play music directly off the device if I want to. The only thing that doesn’t thrill me is that it’s a full sized phone, which can be a bit awkwardly large at times. It’s been working great, but when the time comes for another device, I might go with one of the little Unihertz models.
