Have you ever wondered what your heart rate looked like when you were catching some Zs? Or perhaps you would like to check up on how someone nearby is sleeping, without actually disturbing that person. The ZazHRM monitoring system by Alan Do lets you do both, with a pulse sensor hooked up to an Arduino […]
Your heart is an amazing organ, pumping blood through your body and literally keeping you alive. However, building a realistic model of one — as explained in this write-up by Holiday McAllister — can actually be pretty simple. Here, silicone is poured into a four-inch heart mold to create the structure, partially hollowed out to accommodate a […]
Transgender Awareness Week, which culminates today with the Transgender Day of Remembrance (TDOR), aims at raising the visibility of the transgender and gender non-conforming people, and address the issues their community faces. At Arduino, we believe that technology should improve the lives of everyone, regardless of their gender, sexuality, race, age, ability, nationality, and body. Being […]
If you are looking for a solution to learn and experience the Internet of Things, there are two popular choices: the Explore IoT Kit and the Oplà IoT Kit. But which one should you pick? Here‘s a handy guide. The kits share a very similar set of hardware and are in the same price range; […]
Can robots paint? More specifically, can they create art? The second question is, of course, open for debate, but Technovation’s robotic build shows that they can indeed wield a paintbrush. The device, shaped vaguely like a Roomba vacuum cleaner, uses a pair of NEMA 17 motors for movement and a third to rotate a sort […]
After coming across Carbon Design Group’s Domino Wall Clock, which uses electronic magnetic coil motors to reveal white dots, Instructables member “Kothe” decided to create a simplified version of their own. The clock is comprised of three custom dominoes — the first tile for hours, the second and third for minutes. Unlike its inspiration, Kothe’s […]
If you play beer pong, whether with adult beverages, water, or soda, it’s possible you find it too repetitive or too easy. While one might see this as a self-correcting problem, to take things up a few notches Ty Palowski created a specialized table with moving cups. The custom setup oscillates the cup pyramids back […]
The Arduino Science Journal is a mobile application that allows anyone to conduct scientific experiments by measuring the surrounding world with sensors, documenting and comparing data, developing and validating hypotheses, and taking notes. The app and all learning materials are free, open source, and available for download on Google Play Store, Apple App Store, and […]
To label used bottles that would otherwise go to waste, “tuenhidiy” created a CNC plotter that itself consists mostly of scraps! The machine’s X and Z axes are formed out of a pair of old CD/DVD players, but instead of a traditional Y axis, it actuates two printer rollers to turn a bottle forwards or […]
You’ve probably seen an example of the “useless box,” or “useless machine,” which when switched on does nothing except open up to turn itself back off again. This one by creator Alex Pikkert adds a few new tricks, giving it a bit of a mood, and not one but two switches and fingers! When switched […]
