Morphing Meta-antennas enable frequency manipulation
Reading Time: 2 minutesAn antenna’s physical properties are inextricably linked to its electromagnetic properties and how it radiates and receives radio waves. One of the simplest examples is extension, like with an old cell phone or FM radio antenna. But shape and structure can have more dramatic effects, which is why we have so many…

Forgot your safe combination? This Arduino-controlled autodialer can crack it for you
Reading Time: 2 minutesSafes are designed specifically to be impenetrable — that’s kind of the whole point. That’s great when you need to protect something, but it is a real problem when you forget the combination to your safe or when a safe’s combination becomes lost to history. In such situations, Charles McNall’s safe-cracking autodialer…

SeaPerch II introduces students to underwater ROV exploration
Reading Time: 2 minutesWhile professionals around the world take advantage of Arduino products and the extensive ecosystem, the core Arduino philosophy is to simplify complex technology. A bare microcontroller is intimidating to the uninitiated, but an Arduino development board is friendly and approachable. MIT’s Sea Grant is harnessing that in their new SeaPerch II underwater…

This DIY experimental reactor harnesses the Birkeland-Eyde process
Reading Time: 2 minutesNitrogen is critical for farming at scale and without some form of nitrogen to enrich the soil, we couldn’t grow staple crops efficiently enough to feed our large global population. Serious science goes into the production of fertilizers and the Birkeland-Eyde process was one early example. It uses electrical arcs to turn…

This Arduino device helps ‘split the G’ on a pint of Guinness
Reading Time: 2 minutesGuinness is one of those beers (specifically, a stout) that people take seriously and the Guinness brand has taken full advantage of that in their marketing. They even sell a glass designed specifically for enjoying their flagship creation, which has led to a trend that the company surely appreciates: “splitting the G.”…

This three-fingered robot hand makes use of serial bus servos
Reading Time: 2 minutesA small startup called K-Scale Labs is in the process of developing an affordable, open-source humanoid robot and Mike Rigsby wanted to build a compatible hand. This three-fingered robot hand is the result, and it makes use of serial bus servos from Waveshare. Most Arduino users are familiar with full-duplex serial communication,…

This mod simplifies single-point threading on mini lathes
Reading Time: 2 minutes“Single-point threading” on a lathe is the process of cutting threads, such as for a bolt, into the material through turning. The spindle/workpiece spin and the carriage moves linearly at a precise amount per turn of the spindle. That linear movement is the thread pitch. But this process usually requires several passes…

This robotic piano has solenoids for all 88 keys
Reading Time: 2 minutesPianos famously have a lot of keys. A standard full-size piano has 52 white keys and 36 black keys, for a total of 88. Therefore, people need to get clever when they build self-playing pianos. However, the brute force approach works, too. Paul Junkin’s brute force strategy was to add a solenoid…

This ‘modular server room’ is an interesting scale POC
Reading Time: 2 minutesServer rooms are built for the comfort of servers — not people. But those servers need maintenance, which means they need to be accessible. The resulting access corridors take up room that could be filled with more servers, which is why Jdw447 designed a claw machine-esque ‘modular server room’ and built a…

Motion-controlled Rock ‘Em Sock ‘Em Robots will make you feel like Jackman in Real Steel
Reading Time: 2 minutes2011’s Real Steel may have vanished from the public consciousness in a remarkably short amount of time, but the concept was pretty neat. There is something exciting about the idea of fighting through motion-controlled humanoid robots. That is completely possible today — it would just be wildly expensive at the scale seen in the…

Does your sample contain DNA or RNA? DIYNAFLUOR can tell you on a budget
Reading Time: 2 minutesLab equipment is — traditionally at least — tremendously expensive. While there are understandable reasons for those costs, they are prohibitive to anyone operating outside of a university or corporate lab. But as the “citizen science” movement has grown, we’ve seen more and more open-source and affordable designs for lab equipment hitting…

How to use vintage LED bubble displays with your Arduino
Reading Time: 2 minutesIf you want to add a display to your Arduino project, the easiest solution will likely be an LCD or OLED screen. But though those are affordable and work really well, they may not provide the vibe you’re looking for. If you want a more vintage look, Vaclav Krejci has a great…

Using Arduino UNO to sync a visual neuroscience lab
Reading Time: 3 minutesCommon research methods to study the visual system in the laboratory include recording and monitoring neural activity in the presence of sensory stimuli, to help scientists study how neurons encode and respond, for example, to specific visual inputs. One of the biggest technical problems in the neural recording setups used in such…

Use sound to trigger your camera’s flash with this DIY device
Reading Time: 2 minutesIn the world of photography, the exposure triangle is immutable. To get a properly exposed photo (not too bright or too dark), you need a balance of aperture size (how much light gets in), shutter speed (how long the light gets in), and ISO (sensitivity to light at the expense of noise).…

Transform trash into treasure with the DIY Bottle Plotter
Reading Time: 2 minutesManufacturers put a lot of effort into their packaging (there is an entire engineering discipline just for that) and some of it can be quite beautiful. But it usually still ends up in the landfill or, at best, in a recycling center. However, if you’re the type of person who can see…

Giving Billy Bass the arti-fish-al intelligence he always deserved
Reading Time: 2 minutesIf you were unlucky enough to visit a big box retail store or goofy uncle’s home around the turn of the century, you would have undoubtedly come across a Big Mouth Billy Bass. That’s an animatronic fish that wiggles on a plaque while older, very licensable hit songs play. But while ol’…

This beautiful table creates art in the sand
Reading Time: 2 minutesKinetic sand art tables are pretty hot right now, because they look really cool. They’re like zen gardens that rake themselves in intricate patterns. But most of the builds we’ve seen use a conventional cartesian CNC layout or polar layout. This table by Newsons Electronics takes a different approach inspired by spirograph…
