This is a pretty cool IoT hack: Joseph Ernest took a Raspberry Pi 2, added a USB DAC PCM2704 (Digital-to-Analog Converter), put it inside a box with an SD card reader and some ports, and voilà! A cool sampler box was born!
SampleBox on Raspberry 2
But the only problem with this project it was written in Python and cython Wah-wah-wahhhhh... :-( Sadness. Would someone _please_ port this to Java? C'mon. No one should have to suffer through Python and cython to generate beautiful music! Such a tragedy...
