Without using them, one iPhone or laptop is indistinguishable from another of the same model—to the human eye, at least. A team of researchers, though, has developed a tool that can tell gadgets apart based just on the electromagnetic noise they create.
If you fondly remember drawing circuit diagrams at school, this lamp will make you smile: Its designers created it to mimic the line-drawn circuit plans that make it work.
There are all sorts of variations on Raspberry Pi-powered home automation systems, but ARM Tutorials shows off a pretty simple project that uses Twitter as the backbone.
You don’t need dangerous explosives to put on an impressive fireworks show. Just grab a magnifying glass, a bunch of tiny resistors, capacitors, and transistors, and then blast them with more electricity than they were designed to handle. The results won’t disappoint, as long as you aren’t hoping for a Fourth of July…
The diode is a simple-sounding electronic device that allows current to flow easily in one direction but not the other. It’s a fundamental part of modern electronics and now the world’s smallest has been manufactured from DNA.
Turning a Raspberry Pi into a motion sensing security camera is a classic Pi project, but Microsoft’s put together a bit of a spin on the classic by showing off how to build one using Windows IoT.
Soldering is still an incredibly common and useful process for repairing electronics, but it could be about to get a little cooler. Quite literally, because researchers have developed a new way to solder without heat.
The Raspberry Pi 3 was released this week and while the big talking point is built-in Wi-Fi and Bluetooth, it still gets a bit of a speed bump. So, let’s take a look at just how much faster it is, comparing it to the Pi 2 and a Model B+.
You probably take the DisplayPort on your laptop for granted, but the folks that develop the standard have been working hard to make it perform way better—and the next version will allow you to drive an 8K display with HDR video, if you ever happen to own one.
The sci-fi dream of flexible electronics is on its way—it’s just taking a while to arrive. But this new prototype flexible smartphone, that responds to the way it’s bent and twisted, at least hints at how your future phone may behave.
Transistors are everywhere—in your computer, car, phone, and refrigerator—but they’re not shrinking fast enough to satisfy our hunger for ever-faster devices. A new kind of light-based transistor might just fix that.
There are countless electronic sequencer apps available for your mobile device, but based on the popularity of Teenage Engineering’s tiny Pocket Operator synths, people still like pushing real made-of-matter buttons. That’s why the company is now introducing three new models with its PO-20 series.
If we’ve learned one thing from breathy concept designs and cheesy sci-fi movies, it’s that we all deserve flexible technologies: bio-electric tattoos that measure our vitals and tablets we can roll up to shove in our pockets.
Jamming communications isn’t a new idea, but with battlefields becoming increasingly digital, it’s an evermore concerning threat. Now, though, DARPA has built a super-fast chip that will help create devices able to shrug off radio-frequency attacks.
Soldering has been around for thousands of years: it’s an essential component to electronics around the world. But, there’s some limitations: high temperatures can damage delicate components. Now, some researchers think that they’ve come up with a solution: a room temperature, conductive glue.
Material scientists are able to fuse together nanoparticles into complex miniature devices, but they currently use high temperatures which can damage the materials on which they’re built. Now, a new technique which uses less energy could help print them on plastic or paper.
A telephone regulator has warned that festive decorations can spoil your festive internet fun. Here’s the science.
This humble-looking piece of circuitry, little larger than a quarter, can be used to wirelessly fool magnetic stripe readers into thinking you’ve swiped your card, by generating hefty magnetic fields that mimic the data held on it.
Wooden building blocks have inspired the architects of tomorrow for years now, but littleBits wants to instead inspire future engineers. And with its new Gizmos & Gadgets kit, kids can easily build more than just simple circuits and electronics.
They normally sell for $100 and up, but Dremel has found a way to make its rotary multi-tools a lot cheaper for anyone who already has a workshop full of equipment. Instead of having its own motor inside, the company’s new VRT1 is powered by the suction from a vacuum.
