Balancing robots are always fun to see, as they often take forms we’re not used to, such as a box standing on its corner. This project, submitted by [Alexchunlin], showcases a cool single motor reaction cube, where he dives into many lessons learned during its creation. At the outset, [Alexchunlin] thought this would be a […]

These things were commonly used on telephones back in the day, and they were notoriously slow to use. The way they work is […]

Made from an ESP32 Beetle C6 and using an attached accelerometer with simple thresholds […]
Here is a hacker showing off their engineering chops. This video shows successive design iterations for a LEGO vehicle which can cross increasingly large gaps. At the time of writing this video from [Brick Experiment Channel] has been seen more than 110,000,000 times, which is… rather a lot. We guess with a view count like […]
[Leo Goldstien] recently got in touch to let us know about a fascinating update he posted on the Hackaday.io page for ManiPylator — his 3D printed Six degrees of freedom, or 6DOF robotic arm. This latest installment gives us a glimpse at what’s involved for command and control of such a device, as what goes […]
In a fusion of scrapyard elegance and Aussie ingenuity, [Mark Makies] has given a piece of old steel a steamy second life with his ‘CastAway Tub’. Call it a bush mechanic’s fever dream turned functional sculpture, starring two vintage LandCruiser leaf springs, and a rust-hugged cast iron tub dug up after 20 years in hiding. […]
