No matter how far down the 3D printing rabbit hole we descend, chances are pretty good that most of us won’t ever need to move filament from one spool to another. But even so, you’ve got to respect ...

A clever mechanical clutching/flywheel mechanism gets more energy out of train track vibrations than conventional piezoelectric approaches. Most transducers designed to harvest vibrational energy ...

Long ago, before servo motors and linear actuators were common, clever mechanical devices were what engineers used to produce the needed motion for their processes. The CNC-cut Geneva Drive may not be ...
