AmazingDIYProjects spent countless hours building this crazy loud electric flying contraption using dozens of drone motors. He captured footage of the marvelous machine’s maiden manned flight. Second flight starts at 15:30, and POV footage at 22:30. (Thanks Rob!)
Applied Science takes a look at an intriguing bit of tech that uses piezoelectric waves to move objects. This allows for low-profile, hubless, magnet-free motors and theoretically could create motors which aren’t round. The motor shown in the demo is from PCBMotors.
