Flipdiscs
Summary
This article is a hands-on guide to building a flip-disc (flip-dot) display wall, including hardware (Alfazeta panels, ATMEGA128, RS485 wiring) and framing with 80/20 aluminum. It details a full software stack (Node.js libraries, PIXI/Three.js, Matter.js, GSAP) for real-time visualization, plus ML-enabled processing via NVIDIA Jetson Orin Nano or Raspberry Pi, gesture recognition with MediaPipe, and a REST/WebSocket interface to manage scenes. It also discusses dithering techniques, an Expo-based control app, and a future AI-enabled 'AI Wall' concept.
