(Phys.org)—"Last winter, I fantasized about sitting at my computer while a camera-equipped drone followed him overhead." That is the revelation of a father who provides a detailed account of building an Arduino-based ...
Everyone knows what it's like for an airplane to land: the slow maneuvering into an approach pattern, the long descent, and the brakes slamming on as soon as the plane touches down, which seems to just barely bring it to ...
