Pineapple II
About Pineapple II
Pineapple II is an artist-friendly super-easy-to-use computer. It can covert analog signals to MIDI (digital) signal. You plug power, sensor, MIDI instrument, and everything is set up.
We open-sourced everything you’ll need to copy this tiny computer—the schematic, the artwork, component list, built-in software, and case design. These artworks, codes, configurations, designs, and other documents are open under the GPLv3.
And, prepackaged Pineapple II will be available at Pineapple Store soon.
