The trick: the ESP32 captures a single pixel per laser pulse at a specific moment in time, then accumulates many sequential pixels across many pulses. Since the laser and speed of light are consistent and repeatable, stitching these pixels together reconstructs a continuous ultra-slow-motion video — no exotic high-speed camera required. ## Full article daily.dev links to this article rather than hosting it.
