[GreatScott!] knows this, and rather than put up with the bump and grind of a cheap rotary encoder, he decided to find an alternative. He ended up exploring hard drive motors as encoders ...

Rotary encoders convert a shaft's angular position into an analog or digital code. They are characterized as either incremental or absolute devices: incremental encoders are capable of tracking motion ...

An incremental rotary encoder converts angular motion or the position of a shaft to either analog or digital code. Incremental encoders are often used in feedback systems. These encoders translate ...
