LightSabre
LightSabre is a project designed to control WS281x RGB LEDs using the Secondary Memory Interface (SMI) of a Raspberry Pi, tailored for scenographic and lighting applications.
Features
- WS281x LED Control: High-performance driving of addressable RGB LEDs via the Raspberry Pi SMI.
- ArtNet Support: Receives color data over the ArtNet protocol, allowing the Raspberry Pi to function as a DMX controller.
- Autonomous Mode: Analyzes audio input from an I2S microphone, performing spectral decomposition to generate dynamic lighting effects.
- Web Interface: Local web server for configuring and tweaking autonomous behavior.
- MIDI Integration: Supports real-time control and parameter adjustment via MIDI controllers.
Technology Stack
- Backend: Written in Rust for robust and efficient controller logic. Some low-level operations may be implemented in C or Assembly (to be determined) for optimal performance.
- Frontend: Built with Vue.js, providing a modern and responsive web interface for configuration and control.
Use Cases
- Stage lighting and scenography
- Interactive art installations
- Music-synchronized light shows
