Passive radar for all (as long as you’re a US person) @eldaeonuap 🛸

[ard @ardchain]

a very literal example of giving a small computer eyes

a Raspberry Pi in a moving car is turning the road into a live list of objects

each vehicle gets a label, a bounding box, and a confidence score as it appears in the camera feed

the useful loop is simple:

camera frame → vision result → local rule → physical or network action

the same pattern can run on a much smaller board. my ESP32 vision guide starts with the camera, then shows how to turn what it sees into a reaction

give your ESP32 eyes

[ard @ardchain]

a camera rig tracks a flying drone

watch the crosshair: the drone moves, two servos turn the camera mount, and the target comes back to centre

that is the whole control loop in physical AI:

camera frame → target position → servo correction

my ESP32 vision guide starts with the same loop. the full guide below
