The AI wrote the code for my Halloween skull, and now its eyes follow people

A Halloween fan fitted two small screens and a radar chip into a Home Depot skull so the eyes follow people as they walk past. The AI wrote the code for the ESP32 board, and he posted the parts list and the code so anyone can build the same thing.

How it works

  1. Fit two 1.28 inch screens and a 24 GHz radar chip into a store bought skull
  2. Have the AI write the ESP32 code
  3. Mount the eyes so they turn toward movement
  4. Share the build and code on GitHub

Why it’s worth knowing

The code the AI wrote drives real hardware: a plastic skull whose eyes track people walking past it.
