With a 20,000mAh power bank, you get about 5.5–6 hours. For a full Burning Man night (8–10+ hours), we recommend two power banks and swapping halfway through.

Yes. The Pi Camera Module 3 NoIR has no infrared filter, so it sees in near-darkness — especially with IR LED illumination. The motion detector also works at any light level.

Yes. Drop sclera.png, iris.png, and pupil.png into the assets/ folder and the renderer uses them as parallax layers instead of the procedural eye. You can also set RENDER_MODE=video in config.txt to loop mp4 videos instead.

Any HDMI display works, but the project is designed for round 1080×1080 screens (Waveshare WS070Round). The round shape makes the eyeball illusion convincing.

No — it's optional. The Pi 5 CPU handles face detection fine at 15fps with OpenCV DNN. The AI HAT+ (13 TOPS NPU) lets you run detection at 30–60fps for smoother tracking.

Yes. The centroid tracker follows the largest / closest person, but detects all movement in frame. When someone new approaches, the eye smoothly transitions to track them.

Yes. Power banks under 100Wh (≈27,000mAh) are allowed in carry-on luggage. The 20,000mAh Baseus at 74Wh is well under the limit.

Yes! Run python3 eye_renderer.py --mouse --windowed on any Mac or Linux machine to test with mouse tracking, or --test-webcam for camera tracking.
