Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

These IXARC magnetic encoders withstand harsh environments and are modular for maximum versatility. Rotary encoders measure the rotation of machine shafts and report the results to electronic controls ...

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 ...

I wrote a bit of VHDL for generating inc/dec pulses from quadrature rotary encoders like the CTS Electrocomponents ones I bought from Digikey for a project I worked on recently. This debounce circuit ...

In robotics, movements must be precise and well-controlled. As robots are asked to do more as industry becomes more familiar with the technology, there will be an increasing need for high accuracy ...

Elma’s E18 rotary encoder comes in through-hole and surface-mount versions in the 14.4 x 11.4 x 6.5mm body size. Rotational life is up to 150,000 revolutions, according to distributor Foremost, which ...

Adafruit has made an I2C interface for four rotary encoders. It comes in the form of a PCB with four footprints that accept one of the most common rotary encoder forms (Bournes PEC11 horizontal style) ...

Knob controllers can control volume settings, scroll through web pages, and help edit movies among other uses. You can buy a commercial one from Griffin Technology for $45 or build one yourself with ...

[Mitxela]’s repair of a Roland JV-1080 (a rack-mounted 90s-era synthesizer) sounds simple: replace a broken rotary encoder on the front panel. It turned out to be anything but simple, since the part ...
