Stepper motors are great for a bunch of projects; CNC machines, clocks or robots for example. Sometimes when working on a project that does include a stepper motor and driver, it would be nice to test ...

Stepper motors are a subject that keeps recurring. This little circuit changes a clock signal (from a square wave generator) into signals with a 90-degree phase difference, which are required to drive ...

A team of scientists has perfected the first practical nanoscale power generator, which can generate useful electrical current from a mere squeeze of your fingers. In the future it’ll be able to draw ...

The simple circuit was designed using a 555 timer and pulse width modulation for controlling the speed of DC motor. The pulse width modulation (PWM) pertains to the process of switching the power ...

REDSTONE ARSENAL, Ala. -- A team at the U.S. Army Research, Development and Engineering Center, Aviation and Missile, has recently worked to develop a new dual pulse rocket motor. The Weapons ...
