DIY creator and music YouTuber Brady Y. Lin has unveiled Stradex1, a compact, violin-inspired instrument that blends 3D printing, smart sensors, and open-source hardware into a highly expressive MIDI controller. Designed to be easier to learn yet rich in nuance, Stradex1 offers a fresh take on string performance for musicians, producers, and makers alike.
Stradex1 builds on Lin’s earlier “8-bit Arduino Violin,” created four years ago, and showcases how far his electronics and design chops have come. At its core is the Raspberry Pi Pico 2, paired with a 16-bit ADS1115 analog-to-digital converter for precise signal handling. The neck features a linear potentiometer with more than 32,000 discrete steps, enabling smooth, continuous pitch control reminiscent of a fretless instrument. Instead of traditional strings, four pressure-sensitive buttons on the bout stand in for a violin’s four strings; press harder for more volume, ease off for softer dynamics. Because it speaks MIDI, Stradex1 can drive virtually any software synth or hardware sound module, unlocking an enormous palette of tones—from orchestral textures to electronic leads.
Every part of the body was 3D-printed at home, making the instrument not only portable and sturdy but also easy to replicate or modify. True to its maker ethos, the entire project is open source, with code, design files, and build details available on GitHub so anyone can study, tweak, and build their own.
Beyond Stradex1, Lin’s portfolio includes a harp-playing robot, a MIDI-powered drum setup, a PC game controller, and the earlier 8-bit Arduino violin that inspired this new design. That lineage shows in the Stradex1’s thoughtful balance of affordability, accessibility, and performance features.
Why it stands out:
– Expressive playability: continuous pitch control and pressure-based dynamics for natural, musical expression.
– Maker-friendly design: 3D-printed parts and off-the-shelf components lower the barrier to entry.
– Studio-ready versatility: MIDI output means seamless integration with DAWs, virtual instruments, and synthesizers.
– Open-source foundation: community-driven improvements and custom mods are not just possible—they’re encouraged.
As the first iteration in the Stradex series, Stradex1 sets the stage for rapid evolution. Whether you’re a musician curious about new performance tools, a producer seeking a unique controller, or a DIY enthusiast eager to build your own instrument, this project is a compelling blend of creativity, engineering, and musicality. Keep an eye on Lin’s channel and the project’s GitHub resources for updates, build guides, and future versions.
