Kinetic 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 drawing machines. A […]
The ukulele has a bit of a reputation for being quaint, but it is a legitimate instrument like any other and that means it takes a lot of practice to play competently. Zeroshot is too busy building cool stuff to bother with all of that, so he put his skills to use constructing this robotic […]
Most successful restaurants operating today have to take advantage of online ordering, as a huge chunk of customers have switched to takeout and delivery. But point-of-sale (POS) systems don’t always integrate well into a kitchen’s workflow and that can lead to missed orders — one of the worst things a restaurant can do. To help […]
The traditional backyard chicken coop is a very simple structure that typically consists of a nesting area, an egg-retrieval panel, and a way to provide food and water as needed. Realizing that some aspects of raising chickens are too labor-intensive, the Coders Cafe crew decided to automate most of the daily care process by bringing […]
A month ago, ElectronicLab modified his office chair with an electric car jack, giving it motorized height adjustment. That worked well, but required that he push buttons to raise or lower the seat. Pushing those buttons is a hassle when one’s hands are full, so ElectronicLab went back to the workbench to add voice control […]
The mere presence of a flame in a controlled environment, such as a candle, is perfectly acceptable, but when tasked with determining if there is cause for alarm solely using vision data, embedded ML models can struggle with false positives. Solomon Githu’s project aims to lower the rate of incorrect detections with a multi-input sensor fusion technique […]
Who doesn’t want to explore underwater? To take a journey beneath the surface of a lake or even the ocean? But a remotely operated vehicle (ROV), which is the kind of robot you’d use for such an adventure, isn’t exactly the kind of thing you’ll find on the shelf at your local Walmart. You can, […]
Shortly after attending a recent tinyML workshop in Sao Paolo, Brazil, Joao Vitor Freitas da Costa was looking for a way to incorporate some of the technologies and techniques he learned into a useful project. Given that he lives in an area which experiences elevated levels of pickpocketing and automotive theft, he turned his attention to […]
There is something inherently intriguing about submarines that doesn’t seem to apply to other vehicles. Maybe that reflects our natural fears and phobias, or maybe it is a result of our curiosity about the mysterious depths. Maybe it is simply that most of us will never get the chance to ride in a submarine. But […]
Sphere in Las Vegas is inarguably one of the most notable architectural achievements of the 21st century so far. Gaudy? Maybe. Controversial? Definitely. Interesting? Absolutely — no one can debate that with a straight face. When 15-year-old Ben Kennedy’s bedroom nightlight broke, he decided to use the Sphere as the inspiration for this DIY LED nightlight. […]
