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 ...

This Arduino library is used to control one or more stepper motors. The motors are accelerated and decelerated as they travel to their destination. The library has been optimized for flexible control ...

Stepper motors will spin with greatest torque at speed, when using a power supply voltage that is many times higher than the motor's voltage rating. Don't worry about this, the current setting on the ...

DIY musical instruments are particularly challenging projects, because they not only have to work, they also have to sound good. If even a single piece is out of place, it could throw the entire ...

We’ve seen plenty of motor projects, but [Jeremy]’s DIY Tubular Linear Motor is a really neat variety of stepper motor in a format we certainly don’t see every day. It started as a design experiment ...
