Phyllotaxis: An audio-reactive LED display
15 hours ago
- The author uses code to generate a phyllotaxis pattern based on the golden ratio, resembling sunflowers and succulents.
- The point cloud is Voronoi tessellated to create seed-like cell structures, which are then 3D printed into a physical object.
- Each cell contains an RGB LED, forming a cellular matrix animated with shader-style code, including radial spiral patterns.
- Audio reactivity is added via an I2S mic and Fourier transform on an STM32 board, enabling dynamic responses to sound.
- The project is refined with a bamboo mount, custom PCB, and a second version using 5-fold symmetry PCBs and an ESP32 with Rust firmware.
- The author plans future improvements like easier soldering, better LED types, and protective layers for the paper diffuser.
