Hey, I did another thing!!
Please check out "Harmony," the latest addition to swift-embedded-examples.
Harmony is a Bluetooth speaker with a builtin ferrofluid music visualizer.
Everything you need to build Harmony from scratch is either open sourced now, or will be available soon. This includes the embedded swift firmware, the bill of materials, electrical schematics, and the 3d models.
