A portable music player I’m designing end to end, from the enclosure and circuit board to the companion app.
The companion app works with the bench prototype over Bluetooth LE. The custom V1 board is still in schematic capture.
Why I’m building this
I’m building LINE-R because I want a pocket player I can reach for when all I want to do is listen to music. I want physical controls for things I do by feel, like adjusting the volume, and the space of a phone screen when I’m looking through a large library.
The player stores and plays the music, and the Flutter app talks to it over Bluetooth LE. Building the enclosure, electronics, firmware and app together lets me work out which controls belong on the player and which are easier to use on the phone.
