Using a rather large custom PCB, Hari Wiguna made a Sudoku board using discreet LED displays and a physical keypad.
Most people, buy a book and play Sudoku with a pencil or perhaps just get an app. Those that are really dedicated buy a standalone game, but this wasn’t good enough for Wiguna, who made his own electronic board not out of a normal LCD screen, but from 27 three-character LED modules to display the game on a glowing grid. Input is done via a keypad, which uses the grid layout to allow for two-button selection of any square. Read the rest of this entry »
Maker dad Royce Husain and his daughter Zoey have made it an annual Halloween tradition to build fun and exciting new costumes. Following in the footsteps of last year’s El Niño project and the incredibly popular Minnie Mouse stick figure from 2014, the duo is back with another elaborate getup: a Princess Cumulus thunderstorm that is admittedly “a bit impractical for actual trick-or-treating.” (But cool nevertheless!)
The costume itself consists of a cotton-covered inflatable suit along with LED strips connected to an Arduino programmed to produce a flashing lightning effect.
Developed by researchers at the University of Applied Sciences in Linz, the proCover is a sensor-enabled smart sock that adds sensations to current prosthetic limbs.
Although work on more advanced prostheses continues, commercially available limbs still lack tactile feedback. The proCover addresses this not by modifying or replacing the prosthesis, but by using a sock with piezoresistive force sensors embedded in it. This allows for the user to tell where on a foot it’s being touched, as well as the pressure applied, and it can be set up to suit a user’s needs.
Feedback is provided by vibrating rings that can also be placed on a user’s body where convenient. A version that detects how far a prosthetic knee is bent has also been tested. Read the rest of this entry »
For those living in a high-rise, have you ever wondered what was going on behind the closed blinds of your neighbor’s home directly across from you?
Caretaker is a concept project that explores just that. It consists of a custom-made switch board with which you can control the lights of the flats opposite of yours, providing active entertainment that stimulates your senses better than passive media consumption.
If you want one of your own, simply take a picture of the building that you see from your window and Caretaker will design a laser-cut scale model of it for your use. The prototype runs on an Arduino and is battery-powered, allowing you to freely move it around. Read the rest of this entry »
Inspired by The Goonies movie and The Room game, Guido Bonelli has constructed a piece of Arduino-controlled interactive furniture to entertain his guests.
After what appears to be a massive amount of work involving 3D printing, laser cutting, wiring, and programming, Bonelli has come up with a puzzle box that shouldn’t need any explanation. Using button presses and other interactions with it, participants are able to unlock a treasure box in the bottom, a working wooden safe! Read the rest of this entry »
2PrintBeta solves the problem of cutting multiple cables with an innovative scissors setup.
At times, the 3D printing and engineering company 2PrintBeta needs to cut wires and other assorted materials to length. Sure, they could simply cut them by hand, but that takes time and their business is growing. An industrial cable cutter is quite expensive, so being an engineering company, they decided to make their own using a rather rugged pair of scissors actuated by a bolt attached to a drive disk.
For less than $1,000, Keran McKenzie programmed his car to drive itself… or did he? That is the question, which has led to much debate online over the last couple of hours. (Although Hackaday has revealed the truth, it was one heck of an ad for Arduinos!)
Hoax aside, as hackers begin to see autonomous vehicles in various phases of testing, the question of “why can’t I do that?” is bound to come up. McKenzie seemingly attempted to do just that with an array of five cameras embedded in his 2012 Ford Focus where ultrasonic sensors were formerly mounted. While details of the project are slim (and now we know why), he does mention ‘using’ an Arduino for each camera, interfaced with a master board to put everything together. He also went on to ‘add’ a SparkFun MicroView inside the car for visual feedback of the supposed control system.
With Timothy Giles’ rotating digital picture frame, you’ll never have to endure black bars around your vertical images again!
Rather than accept the poor presentation of vertical images that normal displays offer, Giles instead made his own out of a discarded 27-inch LCD TV. A Raspberry Pi displays the images sideways, then uses an Arduino with a stepper shield to rotate the TV to compensate.
Mechanically, he uses a herringbone gear set to turn the TV, while the Arduino accelerates and decelerates the TV’s rotation to give a smooth transition. It’s a very cool project, and one that makes you wonder “why didn’t I think of that?” Read the rest of this entry »
Last year, we featured an awesome audiovisual project from ANGLE that applied videomapping techniques to their livesets. Now, the Florence-based duo is back with their latest A/V system, “Shining Back,” which was designed in collaboration with JoinT Studio’s Stefano Bonifazi.
Essentially, it’s a grid structure consisting of LED lights that pulse in a geometric matrix to the duo’s live rhythms. The installation runs on an Arduino Uno and uses Mad Mapper and Modul8 software. Read the rest of this entry »
Just days after celebrating the Arduino 101‘s first birthday at Maker Faire Rome, we’ve partnered with Hackster, Intel, and Seeed Studio to launch an exciting new contest. We’re challenging you to unleash the powers of the Intel® Curie™ Module-based board and “Invent Your Future.”
Perhaps you want to build an autonomous boat for collecting ocean pollution data, or a pair of shoes that play different sounds for different exercises, or maybe even a wireless gesture-based home automation controller? Whatever you choose, we want to see how you use the Arduino 101 as the brains behind your next creation.
For those who may not be familiar with the 101, the board combines the performance and low-power consumption of the Intel® Curie™ Module with the simplicity of Arduino. It keeps the same robust form factor and peripheral list as the Uno with the addition of Bluetooth LE capabilities and a six-axis accelerometer/gyro to help you easily expand your creativity into the connected world.
