Motion sensors for home security stick out like a sore thumb, as their shiny white exteriors can be easily seen from a distance. This is made worse when camping, as small, discrete security devices that blend into their surroundings are even harder to come by. This is what inspired Sean Miller to create his own that uses […]
Epilepsy can be a very terrifying and dangerous condition, as sufferers often experience seizures that can result in a lack of motor control and even consciousness, which is why one team of developers wanted to do something about it. They came up with a simple yet clever way to detect when someone is having a convulsive […]
Birds have an amazing sense of direction that aids in migrating across vast distances, and scientists think this is due to their ability to detect magnetic fields — just like a compass. Chris Hill on Instructables wanted a way to experience this for himself by using a sensor and some sort of feedback mechanism to feel a magnetic […]
Arduino library submissions have a new, easier and more transparent workflow that lets the community contribute more, and to do it quickly.
Merely looking at the latest Mars rover, Perseverance, will make almost any nerd giddy with excitement over the amount of cool tech that’s crammed into the vehicle before it gets shot into space. This feeling is what probably inspired Dejan of How to Mechatronics to create his own scaled-down version of the interplanetary vehicle, but […]
Wheeled robots normally have wheels that move in a single axis and steer by using either differential speeds or by pivoting some kind of guide wheel. However, this leads to some drawbacks, the most obvious being an inability to move in really tight spaces. When presented with this challenge, YouTuber James Bruton came up with a great […]
Jacquard looms revolutionized the weaving process by independently controlling each heddle’s position. That made it possible to weave complex patterns. But modern Jacquard looms are very expensive, because they require a solenoid or other means of actuation for each and every heddle. Lea Albaugh and her team at Carnegie Mellon University found an affordable way […]
Portable air conditioners are amazing, especially as we head into the hot summer months. But one big downside is having to place them close to a window that will fit the guard, otherwise it’s really tough getting the hot exhaust air out of the room. This is exactly the problem Hackaday user vincentmakes ran into when he […]
If you’re looking for a fast, fun weekend project, check out these superb ways to learn about the Arduino Cloud, and the amazing projects it enables.
Every parent knows that babies need to sleep in specific conditions. Sudden Infant Death Syndrome (SIDS) is a very tragic possibility and a number of steps must be taken to prevent it, such as avoiding blankets that can restrict an infant’s breathing. But babies can also choke on milk if they aren’t lying in an […]
