Recently I was looking for a simple way to play audiobooks for a family member who is not used to touchscreens. As it turns out there are not many available options that are simple enough to use. As I have never worked with audio players or speaker, this seemed like a useful and straight-forward project.
Making it easy to use does not mean that a device has to look ugly. I tried to build something that looks like a finished product with inspirations from 1980s electronics and Teenage Engineering.

really nice project and Animation !
indeed it would be awesome to be able to read files from a USB stick. I tried, but it’s not that easy to create the data stream from the USB to the DAC… too bad we cannot use the USB as a filesystem as it works with the SD card…
Did anybody manage to do that ?
