[Tobias Kuhn] had watched a YouTube video about a robot arm which used servo motors, and wanted to try making one himself. But he found it hard to get slow or smooth movements out of the servos. Even ...

Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...

Brushless servo motors are all the hype these days. But stepper motors still provide a number of advantages while being more cost efficient and robust. Together with precision linear and rotary ...

As usual, the needs of the application play a major role in determining which is the best type of motor to use. As the shift to automation continues to gain momentum in the industrial sector, servo ...

Texas Instruments (TI) enhanced its high-performance stepper motor-driver familu with the addition of three new devices for 24-V stepper motors. Two devices offer TI's patented AutoTune™ technology to ...

TRINAMIC extends its portfolio of TMCM embedded motor control modules. Following the success of the TMCM-351 triple axis board, the TMCM-3351 is designed to be as easy to use as its sibling, but with ...

To run a stepper motor smoothly, it's necessary to apply linear acceleration. However, conventional algorithms to generate linear acceleration require complicated mathematics, which makes it difficult ...

I like this one - a super impressive Arduino-based barometer for measuring air pressure. There's something satisfying about the link with nature, a tangible connection with outside weather. In a ...

The lure of microstepping a stepper motor for precision must be tempered by torque considerations. The lure of microstepping a two-phase stepper motor is compelling. For instance, microstepping a 1.8° ...
