A desktop app for driving DMX stage lighting, built as a native Tauri app: a Rust core that talks to the hardware and a Vite + TanStack Router + shadcn/ui front end to drive it. Lux runs a full 512-channel DMX universe with user-defined fixtures, patched into named setups (home / church / work) that sync to your account and work offline.
Output goes three ways: an Enttec OpenDMX USB interface, network DMX over sACN / Art-Net (nodes auto-discovered), and remote control from a Discord bot over AWS IoT.
The Rust side keeps the universe 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.
