Encoders are the most widely used feedback devices for electric motor control, capable of delivering precise position and speed feedback for closed-loop performance. With numerous technology options ...

Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...

I wrote up a piece about AustriaMicrosystems’ 12 bit hall-effect rotary encoder and the ebullient and cheerful Mary Bohenek was nice enough to send me a demo board. This thing is a blast—imagine ...

A new generation of magnetic rotary encoders from POSITAL-FRABA combine the ruggedness and simplicity of magnetic measurement devices with the accuracy and dynamic response of optical encoders. Motion ...

A while back, [Rupert] wrote a blog post on using V-USB with the very small, 8-pin ATtiny85. Since then, the space of dev boards for 8-pin micros with USB has exploded, the most recent being ...
