Spotify and Pandora Wireless Remote Track / Artist / Album Display
I use Pandora and Spotify a lot–typically from 7 in the morning until 11 at night. I got frustrated with the Spotify and Pandora apps on my Pixel 2 and their inability to find and control my Chromecast Audio players reliably. I also wanted a quick way to identify new songs or artists I heard without having to find my phone and open an app.
To solve these problems, I moved my music playing ecosystem to Linux and installed a wired Dante digital audio network for audio distribution. Finally I built a retro 14-segment, scrolling, always-on LED display that I could quickly glance at to discover what song was playing without having to find my phone and open an app.
