Raspberry camera / gstreamer / raspivid / raspiraw Teaser video of a closing mouse trap; the whole closing is completed in 0.01s(!). This is an animation from Raspberry v2 camera 640x75 video captured at 1007fps(!), played at 1fps. When the mouse trap bar touches down, it hits the black piezo igniter, showing a spark in front: ![]() ![]() Multiple exposures of 84.3m/s (303km/h) inflight airgun bullet (1012x760 frame scaled to 25%, github repo) |

• U-turn w/o speed (>2m/s) reduction • just swap one motor's direction for some time • slowed down by factor 90/25=3.6 • 90fps slowmo youtube video • positions at start of (overshooted) U-turn, at 90°, 180° and finally before going straight again • Arduebot can do similar U-turn |
