[Matt Denton]’s SpoolBot is a surprisingly agile remote-controlled robot that doesn’t just repurpose filament spool leftovers. It looks exactly like a 2 kg spool of filament; that’s real filament ...

Stepper motors are a mainstay in precision control systems, valued for their simple open-loop operation and high torque at low speeds. Commonly found in CNC machines, 3D printers, and robotics, they ...

An animatronic eye is a mechanical device that is designed to mimic the movement and appearance of a real eye. The circuit we made is powered by Arduino, and can be used for a variety of applications ...

The difference between a half step or half step Rotary Encoder type is how the data signals of the two pins are generated. It depends on the mechanical construction of the notches and contacts inside ...

The difference between a full step or half step Rotary Encoder type is how the data signals of the two pins are generated. It depends on the mechanical construction of the notches and contacts inside ...
