DESCRIPTION

This is a portable music player based on a Raspberry Pi Zero. The first version was made using common modules this made it quite a mess, big and fragile. I designed this PCB to put all these part together on one PCB.

The current version has a music player interface written in Python that can be downloaded from github. There is also a 3D printable case and docking station available on thingiverse.

More information about the build process can be found on Hackaday IO.

Why did I make this?

I made this music player because I wasn't satisfied with the current playback methods that are available. The music streaming services available started to feel like radio stations with the same music repeating, they are also depended on an online internet connection while there might be offline functionality it is still limited by the available storage on your phone.

Since most vinyl records come with a download code for MP3 files a dedicated portable music player with my own offline music collection seemed like a good option. Storage has become cheaper and cheaper in recent years so there should be a couple of music players with a lot of storage, right? Well that's not the case, there are a couple of high end players with enough storage, but these are a couple of hundred bucks. That's why I build the first version using parts I had laying around for a few bucks. Since then I've remade it a couple of times and I've finally come to a version that works completely and could be built for about €80, - including 64GB storage (depended on local pricing).
