Tiny Robots That Grow Taller (And Wider)

Sometimes one just needs an extra hand or six  around the workbench. Since you’re a hacker that should take the form of a tiny robot swarm that can physically display your sensor data, protect you against a dangerously hot caffeine fix and clean up once you’re done. [Ryo Suzuki] and …read more

Plasma Globe Reveals Your Next Clue

If you like solving puzzles out in the real world, you’ve probably been to an escape room before, or are at least familiar with its concept of getting (voluntarily) locked inside a place and searching for clues that will eventually lead to a key or door lock combination that gets …read more

Amplifier Controlled Motorized Display

It’s easy to get jaded by gadgets like the Chromecast or Sonos, which let the user control AV equipment remotely from a mobile device or computer. You can pick something to play from your phone and send it off to your speakers via the magic of Wi-Fi. But it’s still nice to have a display to look at for music visualizations and that sort of thing, at least occasionally.

To address this only occasional desire to have a display on your media setup, you could follow in the footsteps of [Steven Elliott] and create a DIY motorized display which only …read more

Build Your Next Dancing Robot From Empty Soda Bottles

When you think about the materials for your next large dancing robot build, soda bottles might not be the first thing that springs to mind. But they could work, according to TrussFab, a project from a group of students at the Hasso Plattner Instituit. Their system uses empty coke bottles and 3D printed connectors to build large structures, modeled in software that checks their load balance and safety. The team has modeled and built designs up to 5 meters high. Now, the project has taken a step further by adding linear actuators and hinges to the mix so you can …read more

Homebrew Linear Actuators Put The Moves On This Motion Simulator

Breaking into the world of auto racing is easy. Step 1: Buy an expensive car. Step 2: Learn how to drive it without crashing. If you’re stuck at step 1, and things aren’t looking great for step 2 either, you might want to consider going with a virtual Porsche or Ferrari and spending your evenings driving virtual laps rather than real ones.

The trouble is, that can get a bit boring after a while, which is what this DIY motion simulator platform is meant to address. In a long series of posts with a load of build details, [pmvcda] goes …read more

Evolving the 3D Printed Linear Actuator

Our open source community invites anyone with an idea to build upon the works of those who came before. Many of us have encountered a need to control linear motion and adapted an inexpensive hobby servo for the task. [Michael Graham] evaluated existing designs and believed he has ideas to advance the state of the art. Our Hackaday Prize judges agreed, placing his 3D Printed Servo Linear Actuator as one of twenty winners of our Robotics Module Challenge.

[Michael]’s actuator follows in the footstep of other designs based on a rack-and-pinion gear such as this one featured on these pages, …read more

Servo Becomes Mini Linear Actuator

RC servos are a common component in many robotics projects, but [Giovanni Leal] needed linear motion instead of the rotary actuation that servos normally offer. The 3D Printed Mini Linear Actuator was developed as a way to turn a mini servo into a linear actuator, giving it more power in the process.

A servo uses a potentiometer attached to the output shaft in order to sense position, and the internal electronics take care of driving the motor to move the shaft to the desired angle. [Giovanni] took apart an economical mini servo and after replacing the motor with a 100:1 …read more

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
