Warner Electric's newest actuators have a number of new features. A round, ground ball nut makes ball bearing transition a lot more consistent than a tapped square nut, and lasts longer. It also uses bearings to support the motor shaft, not bushings. The actuators also over limit switch and potentiometer options. They are small enough to fit in confined areas, but still can move loads from 25 to 1,330 lbs. They are weatherproofed, too, so they can be used outside. No maintenance is needed either, since the adjustments and lubrication is made at the factory. Stock orders will ship in 24 hours, are handled by Warner Electric's staff, and the actuators are backed by Warner Electric's premium service.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
