The childhood classic tabletop game of Connect Four entails dropping either a red or yellow disc into one of several columns in a grid with the hope of lining up four in a row. And even though the game has existed digitally for a while now, it is mostly played on LCD screens with fancier […]
Health tracking is a vital component to recovering after an injury or simply trying to improve one’s own fitness, and although accelerometer-based devices are decent at tracking general activity, they fail to accurately monitor specific areas of the body such as joint movement. This is why a team of researchers from the Singapore University of […]
If you’re anything like every other human being on the planet, you have several cordless power tools and their batteries are all dead. You never remember to put the batteries on their chargers until you need the tool for a job only to realize that it won’t turn on. Discipline is difficult, so Lance of […]
You’ve probably heard that there isn’t any sound in space. That’s because sound is vibration traveling through a medium, like air or wood, and space is a mostly empty vacuum. The frequency of the vibration in a medium is the pitch of the sound and the amplitude is the volume. If you want a way […]
Counting one’s coins by hand can take a very long time, and for those wanting to avoid physically going to the bank or paying a fee at a commercial machine, what options remain? Fraens has created a full 3D-printed coin sorter and counter that combines technology with a clever design to accomplish this task automatically. The bulk of […]
There are many ways to control a robot arm, with the simplest being a sequential list of rotation commands for the motors. But that method is very inefficient when the robot needs to do anything complex in the real world. A more streamlined technique lets the user move the arm as necessary, which sets a […]
Pipelines are integral to our modern way of life, as they enable the fast transportation of water and energy between central providers and the eventual consumers of that resource. However, the presence of cracks from mechanical or corrosive stress can lead to leaks, and thus waste of product or even potentially dangerous situations. Although methods […]
Many types of medications (such as anti-depressants like SSRIs) can have a very negative effect if they aren’t taken on a regular basis. Even taking them a few hours late can harm a person’s mood and cause physical discomfort. But remembering to take pills at the proper time can be tricky — even setting an […]
Many people find the subjectivity of art to be frustrating, but that subjectivity is what makes art interesting. Banksy’s self-shredding art piece is a great example of this. The original painting sold at auction for $1.4 million — and then it shredded itself in front of everyone. That increased its value and the now-shredded piece, […]
With an array of onboard sensors, Bluetooth® Low Energy connectivity, and the ability to perform edge AI tasks thanks to its nRF52840 SoC, the Arduino Nano 33 BLE Sense is a great choice for a wide variety of embedded applications. Further demonstrating this point, a group of students from the Introduction to Embedded Deep Learning […]
