Did you know that if you take a head of romaine lettuce and eat all but the bottom, then place it in a bowl of water, it will regrow? This fun fact actually inspired Instructables user Evandromiami to develop a deep water culture hydroponic system that would optimize the process for him. The lettuce is grown on top of a […]
Developed as part of a semester project, BINARY IO is a nifty little MIDI controller capable of counting from one to 15 using only four buttons. The device, which uses binary code as an input mechanism, is powered by an Arduino Uno and Max/MSP. With a little practice, BINARY IO becomes quite intuitive and fun to play. As demonstrated by its […]
You know that rotating hourglass that indicates when a Windows application is busy performing an operation? Well, interaction designer Wolfgang Huther decided to bring the iconic cursor into the real world with an Arduino-driven project he calls “The Microsoft Hourglass Machine.” The wall-mounted display was brought to life using laser-cut acrylic parts, black sand, and some electronics.
The Shower Thoughts subreddit is a collection of all those ideas or philosophical questions that race through your mind while in the bathroom. For example, “I like to think money wouldn’t change me; yet when I’m winning Monopoly I’m a terrible person,” or “12 years ago leaving CDs out in my car gave theives a reason to […]
Longtime artist Jeff Leonard has built a pair of Arduino-driven CNC painting machines with the motivation to grow his toolbox and expand the kinds of marks he could make simply by hand. By pairing the formal elements of painting with modern-day computing, the Brooklyn-based Maker now has the ability to create things that otherwise would’ve never been possible. Machine #1 consists of a 5’ x 7’ table and […]
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 […]
