A team from ETH Zurich has created an incredible submersible robot called Scubo as a way to scan entire coral reefs. Equipped with six onboard webcams, the omnidirectional device is capable of exploring the deep sea from every angle. What’s more, users can take a virtual dive by throwing on a pair of VR glasses to make it feel as if they’re […]
Connor Nishijima has devised a neat trick to give the standard Arduino Tone() function 256 smooth volume levels using PWM at an ultrasonic frequency, without any extra components. This allows for programmatic control of square waves with nothing other than a speaker connected to an Arduino Uno.
Project-based lessons are a great way to introduce students to the world of electronics. Clearly Jenna Debois agrees, as she has built a DIY classroom clock based on an Arduino Nano. What’s even cooler is that it’s optimized for teachers!
An entry in this year’s Hackaday Prize, Dtto is a snake-like robot designed to be modular and self-reconfigurable. Inspired by Bruce Lee’s famous water quote, Dtto can transform into various shapes by changing the position and connection of its 3D-printed modules. As Hackaday points out, each section of Dtto is a double-hinged joint. When two come together, magnets help them align. A […]
Jochen Maria Weber’s Foxes Like Beacons is an exploratory project using open data of public radio stations with inexpensive, low-power signal detection in order to create an open positioning system. According to the designer: Today’s satellite based GPS enable and augment uncountable everyday processes, ranging from logistics to fitness trackers and even intimate dating applications. These proprietary […]
“Push Button, Receive Bacon” is a popular catchphrase and graffiti tag often spotted next to the graphic instruction on hand dryers. Well, the Hammerspace Workshop team has decided to bring that meme to life with their latest project for the upcoming Maker Faire Kansas City. In order to raise awareness of the link between bacon and hand health […]
Electric Daisy Carnival Las Vegas is just days away, and YouTuber “Korberos” is ready. The Maker has created an LED Pac-Man totem using 967 lines of code, 256 NeoPixels wired in succession and laid out in a game-inspired map, and an Arduino Pro Mini. The controller and game lights are powered by a 5V power bank with 10,000mAh of storage, […]
If you’ve always wanted a bot for a friend, personal assistant or butler, you’re in luck. John Choi, a Carnegie Mellon University computer science and arts student, has managed to build his own life-size robotics platform for about $2,000. Sure, a price tag like that may not seem “cheap” but in comparison to other research-grade platforms out there, it’s a bargain. Ideal […]
Lights synchronized to music, what’s not to love? YouTuber “Robert Robert” has done just that using 24 acrylic blocks, an Arduino Uno, four 12-pixel WS2812B addressable LED strips, an Adafruit electret microphone amplifier, a 12000mAh external battery pack, and some code. The blocks are divided into two sets of 12, held together by threaded rods and nuts, with LED strips hot glued to […]
Last year, Moscow-based artist Dmitry Morozov — known by many as ::vtol:: — came up with a far less modern way of taking selfies. The Maker modified an old Brother SX-4000 typewriter to create portraits in the form of ASCII art. The machine, called “i/o,” is controlled by an Arduino Mega and works by capturing an image using an iSight camera (with […]
