Collaborate Disseminate
In the name of saving weight and pushing plastic, it’s nice to see continuous tweaks on 3D printer extruders from folks in their spare time. And to go where no …read more Continue reading Rolling-Screw Extruder Goes Brushless
Over the weekend, Sanjay Mortimer passed away. This is a tremendous blow to the many people who he touched directly and indirectly throughout his life. We will remember Sanjay as …read more Continue reading Remembering Sanjay Mortimer, Pioneer and Visionary in 3D Printing

As long as 3D printers have been around, it seems as though many of us have dreamed about nozzle-sharing solutions for multicolor 3D prints. Just because Prusa’s MMU has had …read more Continue reading Enraged Rabbit Project is a Filament Cocktail Special
In a world where smartphones have commoditized precision MEMS Sensors, the stage is set to reimagine clusters of these sensors as something totally different. That’s exactly what [chronopoulos] did, taking …read more Continue reading Laser Theremin Turns Your Hand Swooshes into Music
Legged robots span all sorts of shapes and sizes. From the paradigm-setting quadrupeds built from a pit-crew of grad students to the Kickstarter canines that are sure to entertain your …read more Continue reading Wild Lego-Bot Pronks About your Patio
When it comes to legged robots, it’s easy to think that the complexity and machining costs would keep these creatures far away from becoming anyone’s garage hobby. But, through a …read more Continue reading Capstan Drive is Pulling the Strings on this Dynamic Quadruped
The working principle of digital calipers is mysterious enough that we’d never think to dismantle, much less improve them, right? Well, think again, as [Limi DIY] retrofits the processing element …read more Continue reading Custom Caliper Tracks for When You’re Going the Distance
If you march sufficiently deep into the wilderness of control theory, you’ll no doubt encounter the inverted pendulum problem. These balancing acts have emerged with a number of variants over …read more Continue reading Ball Balancing Wheel Puts a Spin on Inverted Pendulums
Brushless DC (BLDC) motors are standard fare in low-precision, speedy RC applications. The control schemes needed to run them slowly or precisely go deep into motor theory and might put …read more Continue reading SimpleFOC Demystifies Precision BLDC Motor Control
