Recycle your old Spotify playlists into new ones
I wanted a way to quickly generate new Spotify playlists from my library based on some simple user inputs.

It works well for my purposes but everybody uses Spotify differently so I'd love some feedback :) Built using React and the Spotify Web API.

Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
