Hackaday Prize Entry: 3D Printed Linear Actuator Does 2kg+

The rabbit hole of features and clever hacks in [chiprobot]’s NEMA17 3D Printed Linear Actuator is pretty deep. Not only can it lift 2kg+ of mass easily, it is mostly 3D printed, and uses commonplace hardware like a NEMA 17 stepper motor and a RAMPS board for motion control.

The main 3D printed leadscrew uses a plug-and-socket design so that the assembly can be extended easily to any length desired without needing to print the leadscrew as a single piece. The tip of the actuator even integrates a force sensor made from conductive foam, which changes resistance as it is …read more

Hackaday Prize Entry: Customizable Linear Actuators

The current state of robotics, 3D printers, and CNC machines means any shade tree roboticist has the means to make anything move. Do you want a robotic arm? There are a dozen designs already available. Need an inverted powered pendulum? There are a hundred senior projects on that every semester. There is, however, one type of actuator that is vastly underutilized. Linear actuators aren’t ‘maker’ friendly, and building a customized linear actuator is an exercise in pain.

For their Hackaday Prize entry, the folks at Deezmaker are changing the state of linear actuators. They’ve created ‘Maker Muscle’, a linear actuator …read more

PLC and Linear Actuators Automate Double-Hung Windows

Very few residential architectural elements lend themselves to automation, with doors and windows being particularly thorny problems. You can buy powered doors and windows, true, but you’ll pay a pretty penny and have to go through an expensive remodeling project to install them. Solving this problem is why this double-hung window automation project caught our eye.

Another reason we took an interest in this project is that [deeewhite] chose to use a PLC to control his windows. We don’t see much love for industrial automation controllers around here, what with the space awash in cheap and easy to use microcontrollers. …read more
