Outer Wilds was top-of-the-line video video games of 2019. It let gamers discover a complete photo voltaic system of miniature planets, with a time loop mechanic that added stress to unravel an interplanetary thriller. However in the event you slowed down sufficient to absorb the ambiance, you’d have seen many small worldbuilding particulars. A kind of was a singular instrument that regarded like a cross between a guitar, a hurdy-gurdy, violin, and a music field. In a exceptional feat of artisanal engineering, Acoustic Anomalies managed to construct a practical reproduction of that Outer Wilds instrument.

The one data we’ve got in regards to the in-game instrument is what we see and listen to whereas enjoying. It appears to have two mechanisms that produce notes. The primary is a spinning drum with protruding pins that strike brass bars, form of like a music field. The opposite is sort of a single string of a violin, performed with a bow.

Acoustic Anomalies initially meant to make the reproduction manually playable and to present it the flexibility to play itself. However he scratched that first purpose, so the ultimate instrument works extra like a participant piano than one thing like a violin. One stepper motor turns the brass drum at a particular velocity, whereas a second stepper motor strikes a nut alongside the fret board to vary the efficient size of the string and due to this fact the notice it produces.

A Teensy growth board controls these stepper motors and makes use of sensors to watch their positions and rotation speeds. Acoustic Anomalies programmed it throughout the Arduino IDE and it accepts an array of notes that can play in sequence. The brass drum has fastened pins so the order of notes cannot change — solely the velocity. However the fret nut can slide up and down the fret board to play notes in any order. That does not, nevertheless, produce any notes by itself. An individual must transfer a bow throughout the string to try this.
