Overview

• Google released open-source build materials on GitHub, including 3D-print models, PCB designs, parts lists and documentation.
• The full layout uses nine rotary dials to cover letters, functions and modifiers, with a dedicated dial for the Return key.
• Typing involves inserting a finger into a dial, rotating to the stop, then releasing so the dial’s return registers the chosen character.
• The system replaces traditional pulse dialing with sensors that translate dial movement into USB input signals.
• The project is a DIY concept rather than a product for sale, and the designers also built a companion stand that can cut your webcam feed when a mouse rests on it.
