[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 ...

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 ...

Linear encoders sense and digitize linear position and movement. A linear encoder is a sensor linked to a scale. The sensor reads the scale and converts position into an analog or digital signal that ...
