This library uses a PCF8575 to read the pulses of a rotary encoder. As a PCF8575 has 16 lines up to 5 decoders with a switch can be read over I2C. The PCF interrupt line can be used to detect changes ...
Abstract: This paper presents a precision capacitive rotary encoder that integrates a shared charge amplifier, and a multi-stage offset calibration scheme. Recently, capacitive encoders have gained ...
A custom rotary CNC-style plotter for drawing directly onto golf balls. This machine takes artwork, converts it into toolpaths and G-code, rotates the ball under a pen, and plots onto a curved surface ...
