Ball and socket joints are useful, but making a part slide over the surface of a sphere, held by magnets, requires a lot of fiddling to get right. We admire …read more Continue reading Practice Makes Perfect for this Ball and Socket Robot
The wonders of 3D printing don’t stop coming. Whether it’s printing tools on the International Space Station, printing houses out of concrete, or just making spare parts for a child’s toy, there’s virtually nothing you can’t get done with the right 3D printer, including spicing up your Halloween decorations.

In one hand you hold the soldering iron, in the other the solder, and in two more hands the parts you’re trying to solder together. Clearly this is a case where helping hands could be useful.

One reason is to take advantage of standardized, open source …read more

Is this a case of a good design gone wrong in the build phase? Or is this DIY prosthetic arm a poor design from the get-go? Either way, [Will Donaldson] needs some feedback, and Hackaday is just the right place for that.
Up front, we’ll say kudos to [Will] for having the guts to post a build that’s less than successful. And we’ll stipulate that when it comes to fully articulated prosthetic hands, it’s easy to fail. His design is ambitious, with an opposable thumb, fingers with three phalanges each, a ball and socket wrist, and internal servos driving everything. …read more
