The Magna Doodle is a classic children’s toy that works by embedding a layer of iron shavings just below the surface of a canvas and then using a magnetic pen to pull them up, thus showing whatever lines might have been drawn. Steve Turner had the idea to automate this drawing process by converting his Magna […]
We’re relaunching Arduino User Groups, so you can get together in person once again to share the Arduino love with other people in your maker-hood.
Arduino Cloud has a new container for all the cloud services, giving you a cool new experience for entering the Cloud.
In the Star Wars Universe, the Jedi and Sith use the Force for battle and mayhem. But in the real world, people would use the Force for much more mundane everyday tasks. Obi Wan even does this in the prequel trilogy when he closes a door using the Force. Star Wars fanatic Nick O’Hara leveraged […]
Most air quality-sensing devices integrate their sensors into the same enclosure as the display, which can make getting an accurate reading tough since the viewer is directly next to the unit and could potentially skew the values. This is why one element14 community member Enrique Albertos created his own portable air quality monitor that separates the sensing […]
So many tasks within a house can be reduced to a series of somewhat simple movements that are repeated each time that task is done, thus making it a prime target for automation. To make this process far easier than the traditional one of designing a robot by hand, writing some code and doing thorough […]
AutoCAD is conventional 2D CAD (drafting) software that still contains many “legacy” features that you won’t find in modern 3D CAD programs. One of those features is the command line, in which users can type short commands to perform various functions or launch tools. For example, typing “line” and pressing Enter will launch the line […]
With the rapid pace of solar panel installations over the course of the previous decade, there has been an ongoing challenge of trying to improve their efficiency. Apart from the typical silicon crystal photovoltaic cells, there are also more efficient/expensive cells known as concentration photovoltaics (CPV), which rely on a set of mirrors to focus […]
Our reliance on electronic devices and appliances has never been higher, so when the power goes out, it can quickly become an unpleasant and inconvenient situation, especially for those who are unable to prepare in time. To help combat this problem, Roni Bandini has devised a device he calls “EdenOff,” which is placed inside an electrical outlet […]
When imagining motion sensors, devices such as accelerometers, infrared detectors, and LiDAR units probably come to mind. But due to the complexity and oftentimes high costs of these parts, researchers Joseph Liew and Keng Wei Ng from the National University of Singapore wanted to create a lower-cost and easier-to-assemble alternative. Their solution, called ESsense, uses the […]
