[Will Finucane] of Revolt Labs/Mad Science Blog was looking for a way to keep his cats happily fed while away on a short vacation, so he put together a cheap and easy automatic feeder to ensure that ...

Linear actuator uses a lead screw driven by a permanent magnet dc motor to create linear motion from a dc voltage. When power is removed linear actuator will hold its position. However, if a force ...

Stepper motor linear actuators provide thrust along a linear axis but cannot tolerate side loading. Supplemental guidance is needed to protect against external forces impacting the linear motion of ...
