Stepper motors are great for projects that require accurate control of motion. 3D printers, CNC machines and plotters are often built using these useful devices. [InventorArtist] built a stepper-based ...

In staring at the photo-real drawing of the perfect bird, you marvel over the technical ability required to produce it. You also study the sloppy sketch just as long, picking out each one of its flaws ...

Pop-up book maker and paper engineer Robert Sabuda has teamed up with the Leonardo da Vinci Robot Society to create a build-it-yourself drawing machine that's based on a rumor, that da Vinci's ...

Engineers rely on motion-control devices to improve efficiencies and production rates on automated factory floors, or at least maintain them. One family of such devices, stepper motors, is widely used ...
