[Ancient] has a video showing off a fascinating piece of work: a lip-syncing robot whose animated electro-mechanical mouth works like an IBM Selectric typewriter. The mouth rapidly flips between ...

Arduino library support for STMicroelectronics PowerSTEP01 stepper driver chip with voltage and current mode drive. This library is a modification of Megunolink powerSTEP01_Arduino_Library which is a ...

Microcontrollers may dominate today’s stepper motor projects, but there’s a certain charm in driving them with pure CMOS logic. This no-firmware approach strips things down to the fundamentals of ...

Abstract: In recent years, the trapezoidal accelerationd and deceleration algorithm has been widely used in 3D printing stepper motor control research, but the algorithm is prone to problems such as ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...
