A desktop app for driving DMX stage lighting, built as a native Tauri app: a Rust core that talks to the hardware and a Next.js + shadcn/ui front end to drive it. Lux controls an Enttec OpenDMX USB interface two ways — directly from the desktop UI, and remotely from a Discord bot over AWS IoT.
The Rust side keeps a DMX channel buffer continuously synced to the hardware (apps/desktop/src-tauri/src/{buffer,channels,sync}.rs) behind a device abstraction (apps/desktop/src-tauri/src/devices/); the UI talks to it over tauri-typed-ipc — a type-safe IPC crate I wrote — so the Rust↔TypeScript command layer is type-safe end to end.
Setting fixture color live from the desktop UI — the RGBAW tube and the Enttec OpenDMX USB interface (bottom) respond in real time.
