Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

As you may have noticed, I’ve been working with an STM32 ARM CPU using Mbed. There was a time when Mbed was pretty simple, but a lot has changed since it has morphed into Mbed OS. Unfortunately, that ...

If you’ve ever spent time in a modern BMW, you’ve probably fussed about with the goofy iDrive controller. It’s a rotary knobbery slidery thing that just never really feels that good to use. [Garage ...

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 ...

Today will be a largely cloudy and dry day, with just the odd spot of rain in places. Some sunny spells will develop in the late afternoon. Tonight Tonight will start partly cloudy. As the night ...

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 ...

Abstract: This article introduces an inexpensive Wiegand-sensor-based rotary encoder that avoids rotating magnets and is suitable for electrical-drive applications. So far, Wiegand-sensor-based ...

A full turn around a point equals 360º. If a full turn equals 360º, then the sum of the angles around a point must also be 360º. When you calculate angles around a point, you can use this fact to find ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. from a ...

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 ...
