Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

Camera sliders are great creative tools, letting you get smooth controlled shots that can class up any production. [Anthony Kouttron] decided to build one for an engineering class, and he ended up ...
