It’s little secret that stepper motors are everywhere in FDM 3D printers, but there’s no real reason why you cannot take another type of DC motor like a brushless DC (BLDC) motor and ...

[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 ...

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 ...

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 ...
