Sensors like the TCS34725 from Adafruit can detect a single color. It stands to reason then, that if you were to aim this sensor at a multitude of points and record the resulting data, you could have a one-pixel camera. As seen here, Tucker Shannon decided to take this concept and run with it, constructing […]
Drones come in many shapes and sizes, but for the most part their motor pods are fixed during flight. Inspired by the way birds can fold their wings, researchers from the University of Zurich and EPFL have come up with a quadcopter capable of changing motor orientation dynamically in mid-air. This allows the nominally X-shaped drone […]
All of us have daily tasks we need to perform, but what if you often forget whether you’ve done something, or simply need to give your child a little extra motivation? One great way would be Simon Prickett’s Arduino Task Tracker, inspired by Simone Giertz’s Every Day Calendar. Prickett’s clean-looking device is built into an […]
Six-legged robots are nothing new, but if you’d like inspiration for your own, it would be hard to beat this 22 servo-driven, 3D-printed hexapod from Dejan at How To Mechatronics. The ant-inspired device features three metal geared servos per leg, as well as a pair to move the heat, another for the tail, and a […]
LED strips reacting to sound is nothing new; however, Paul Shulman’s setup does things a bit differently. Instead of responding to the tune’s overall volume, one musical frequency is analyzed and averaged; if the intensity changes sufficiently on that particular frequency, the corresponding lighting effect is also changed. This avoids the problem of analyzing a […]
What do you do when you need to attach 400-500 screws for an upcoming project? If you’re “Progress Thailand” you simply create one yourself using a 9g micro servo modded for continuous rotation, an Arduino Nano, and some 3D printing! The build uses a small thumb joystick for proportional control, and can accommodate a small hand […]
Bigger isn’t always better, as illustrated nicely by this device from YouTuber “Volos Projects.” It’s not only physically quite small, squeezing an Arduino into a 40x25x25mm aluminum enclosure, but uses an interface consisting of a single button (plus a power switch). Data output is handled via a similarly tiny 64×48 pixel OLED display. Regardless of […]
In the build shown below, Evan McMahon dares to ask the question, “Have you ever been disappointed by a mood ring?” While that might seem a bit random, the answer is a likely “yes” if you’ve ever worn one with the expectation of any sort of accuracy. Fortunately, he didn’t just pose the question, but […]
As first reported by the Des Moines Register, this year 14-year-old Josiah Davenport decided to animate 3,500 Christmas lights on his family’s home with the help of an Arduino Mega. The lighting pattern is synchronized with the Trans-Siberian Orchestra’s “Wizards in Winter,” which passersby can listen to by tuning in to 89.5 FM on their […]
It’s that time of year again, when many the world over chop down a tree, then insert it into some sort of water dish to keep it green for a month or longer. This normally works out well, but means that someone has to keep it hydrated, climbing under sharp branches to intermittently check the […]
