When the tool you need doesn’t exist, you have to make it yourself. Come to think of it, even if the tool exists, it’s often way more fun to make it yourself. The former situation, though, is one that [Sean Hodgins] found himself in with regard to threaded inserts. Rather …read more

Hackers being as a rule practical people, we sometimes get a little guff when we run a story on an art installation, on the grounds of not being sufficiently hacky. We understand that, but sometimes the way an artist weaves technology into their pieces is just too cool to pass …read more

For humans, life is in the eyes. Same deal with automatons. The more realistic the eyes, the more lifelike (and potentially disturbing) the automaton is. [lkkalebob] knows this. [lkkalebob] is so dedicated to ocular realism in his ultra-real eyeballs that he’s perfected a way to make the minuscule veins from …read more
Once a program has been debugged and works properly, it might be time to start optimizing it. A common way of doing this is a method called profiling – watching a program execute and counting the amount of computing time each step in the program takes. This is all well …read more

We have semi-fond memories of string art from our grade school art class days. We recall liking the part where we all banged nails into a board, but that bit with wrapping the thread around the nails got a bit tedious. This CNC string art machine elevates the art form …read more

Long cables are only neat once – before they’re first unwrapped. Once that little cable tie is taken off, a cable is more likely to end up rats-nested than neatly coiled.
Preventing that is the idea behind this 3D-printed cable reel. The cable that [Kevin Balke] wants to make easier to deal with is a 50 foot (15 meters) long Vive lighthouse sync cable. That seems a bit much to us, but it makes sense to separate the lighthouses as much as possible and mount them up high enough for the VR system to work properly.
[Kevin] put a good …read more

It’s doubtful that the early pioneers of CNC would have been able to imagine the range of the applications the technology would be used for. Once limited to cutting metal, CNC machines can now lance through materials using lasers and high-pressure jets of water, squirt molten plastic to build up 3D objects, and apparently even use needle and thread to create embroidered designs.
It may not seem like a typical CNC application, but [James Kolme]’s CNC embroidery machine sure looks familiar. Sitting in front of one of the prettiest sewing machines we’ve ever seen is a fairly typical X-Y gantry …read more

Recently, one of [Eric]’s clients asked him to design a bottle. Simple enough for a product designer, except that the client needed it to thread into a specific type of cap. And no, they don’t know the specs.
But that’s no problem, thought [Eric] as he turned on the exhaust fan and reached for the secret ingredient that would make casting the negative image of the threads a breeze. He mixed up the foul-smelling body filler with the requisite hardener and some lovely cyan toner powder and packed it into the cap with a tongue depressor. Then he capped off …read more

They hold together everything from the most delicate watch to the largest bridge. The world is literally kept from coming apart by screws and bolts, and yet we don’t often give a thought to these mechanisms. Part of that is probably because we’ve gotten so good at making them that they’re seen as cheap commodities, but the physics and engineering behind the screw thread is interesting stuff.
We all likely remember an early science lesson wherein the basic building blocks of all mechanisms laid out. The simple machines are mechanisms that use an applied force to do work, such as …read more
They say charity begins at home, well IoT security probably should too. The growing number of Internet enabled and connected devices we populate our homes with continues to grow year on year – yet, with each new device we connect up, the less confident… Continue reading Consumer IoT Security v1.01
