Stradex1 is a Homebrew Violin That Hits All the Right Notes, Thanks to 3D-Printing and a Raspberry Pi

Brady Lin transformed his failed four-year-old Arduino violin simulator into the Stradex1, a sophisticated 3D-printed electronic violin that uses a pressure-sensitive ribbon strip to detect finger positions with 32,000 gradations for smooth sliding between notes. The device features a Raspberry Pi Pico 2 that processes inputs 200 times per second and outputs MIDI commands to computers or synthesizers, with all design files freely available on GitHub for under $100 in parts.
