I forgot where I saw someone asking about an iPod-like music player, so hopefully this community is okay for this type of post.
Tanagra reached its funding goal very quickly earlier this year because a lot of us want the simplicity of portable, offline listening that the original iPods gave us. However Tanagra goes even further to create a more customizable experience, and runs on open-source software. Take a look at their main page.
Tangara is a portable music player. It outputs high-quality sound through a 3.5 mm headphone jack or Bluetooth, has great battery life, and includes a processor that’s powerful enough to support any audio format you can throw at it. It’s also 100% open hardware running open-source software, which makes it easy to customize, repair, and upgrade. Tangara plays what you want to hear, however you want to hear it.
Listen to music, audio books, and podcasts on a purpose-built device with a tried-and-true form factor, a familiar user interface, and no interest in your data. Or tear it apart and put it back together again. By tweaking our current firmware, you can experiment with alternative user-interface patterns, new types of content, tracker-based music production, alarm-clock applications, and much more. Or you can design a new faceplate with a different kind of display panel, more physical buttons, speakers, different jacks, or…a custom cherry-wood enclosure? Whatever turns your touchwheel.
