OPEN-SOURCE ROBOTIC ARM FOR ALL PURPOSES

A set of helping hands is a nice tool to have around the shop, especially if soldering or gluing small components is a common task. What we all really want, though, is a robotic arm. Sure, it could help us set up glue or solder but it can do virtually any other task it is assigned as well. A general-purpose tool like this might be out of reach of most of us, unless we have a 3D printer to make this open-sou ...

SPRINGS AND THINGS WRAP INTO A POLYHEDRON OF INTERACTIVE LED ART

Any resemblance between The Wobble Sphere and a certain virus making the rounds these days is purely coincidental. Although as yet another project undertaken during the COVID-19 lockdowns, we can see where the inspiration came from. Wobble Sphere is another work of interactive art from the apparently spring-driven imagination of [Robin Baumgarten], whose Quantum Garden piece graced our pages last year. The ...

FOUR ON THE FLOOR FOR YOUR VIRTUAL RACE CAR

There was a time when building realistic simulations of vehicles was the stuff of NASA and big corporations. Today, many people have sophisticated virtual cockpits or race cars that they use with high-resolution screens or even virtual reality gear. If you think about it, a virtual car isn’t that hard to pull off. All you really need is a steering wheel, a few pedals, and a gear shifter. Sure, you can build ...

3D PRINTING A MACRO PAD, SWITCHES AND ALL

Building a macro pad inside of a 3D printed enclosure is hardly news these days. Neither is adding 3D printed keycaps to the mix. But if you go as far as [James Stanley] has, and actually print the switches themselves, we’ve got to admit that’s another story entirely. Now you might be wondering how [James] managed to print a mechanical keyboard switch that’s the size of your garden variety Cherry. Well, the ...

REMOTE CODE EXECUTION ON THE N64

Some like to garden in their spare time, while others prefer to smoke cigars or fold complicated origami figurines. Security researcher [grifter] [CTurt] seems to enjoy cracking consoles instead, and had a go at exploiting the Nintendo 64 over an obscure modem interface. The 1990s were a wild time, where games shipped in cartridges. This format opened up crazy possibilities to add additional hardware to the ...

uStepper – Controlling Stepper Motor with ease

But what is uStepper? In short, uStepper is a product, improving performance of a motor type called “stepper motors”. Stepper motors are used in a wide range of applications where you have to move something, a certain distance, precisely! For example, they are used in your inkjet printer for moving the ink cartridge back and forth over the paper. Stepper motors are precise and really cheap compared to the a ...

NO NEED FOR SPEED WITH THIS ARDUINO-BASED INKJET PRINTER

When it comes to computers, it seems like the only thing that matters is speed. The more the better, in general, and the same applies to peripherals. We want the fastest network adapters, the fastest video card, and the fastest printer. So why in the world would anyone intentionally build a really slow inkjet printer? For art, of course. At least that’s the story [HomoFaciens] tells us in the video below. H ...

ARDUINO MUSIC BOX TURNS STUFFED ANIMAL INTO TV PERSONALITY

Childlike imagination is a wonderful thing. The ability to give life to inanimate objects and to pretend how they’re living their own life is precious, and not for nothing a successful story line in many movies. With the harsh facts or adulthood and reality coming for all of us eventually, it’s nice to see when some people never fully lose that as they get older. Even better when two find each other in life ...
