Arduino is headed to Maker Faire Bay Area!

Maker Faire is a three-day, family-friendly event that has been celebrating the DIY Movement for the last 10 years. The ‘Greatest Show & Tell on Earth’ is designed for creative, innovative people of all ages and backgrounds, who like to tinker and love to make things.

In just a few days, the Arduino team will be in attendance for the 11th annual Maker Faire Bay Area as a Goldsmith Sponsor. Those heading to the San Mateo on May 20th-22nd will want to swing by our booth (#2321) and join us for some inspiring talks, especially the highly-anticipated State of Arduino by Massimo Banzi on Saturday at 12:30pm.

We’ve been preparing a series of demos to showcase the family of Arduino tools for the Internet of Things through our Arduino Create platform. Those who come by our booth will have the chance to experience the following firsthand:

  • Cloud Sensor Station | “Make Sense of Your Data”
    The Cloud Sensor Station is equipped with four different sensors: gas detection, light intensity, motion detection (infrared) and temperature/humidity. These four sensors send values to the Arduino Cloud so that you can see real-time results of the collected data from everywhere.
  • Yún Camera | “Lights! Camera! Facebook!”
    The Yún Camera captures photos at the press of a button and then automatically uploads them onto Facebook. (We’re sensing plenty of selfies in our near future!)
  • Yún Message | “Leave a Message and I’ll Show It Back”
    The Yún Message is a smart desk, developed in collaboration with Opendesk, that displays custom messages on an LED matrix. This piece of smart furniture lets users share a reminder or note through a webpage. Come and leave a note or… do it online!
  • Twitter Printer | “The IoTweet!”
    This connected thermal printer running on MKR1000 will automatically print tweets from all over the world with the #PrintArduino hashtag. (Look forward to seeing what you come up with!)

Additionally, we’ll be showcasing our Creative Technologies in the Classroom (CTC) program, which is a collaborative learning curriculum designed for schools that wish to incorporate emerging technologies into their existing technology classes.

Whether you’re a teacher or student, come and discover how to explore electronics through a series of hands-on coding projects that’ll provide you with the foundations of programming, electronics and mechanics.

Aside from some of our latest products and projects, we’ll also play host to several members of our growing open-source ecosystem and partners like Intel, ARM and Atmel, to name just a few.

Have a question about Arduino? Looking to get started but don’t know how? Beginners, or even experienced users, will have the chance to get their questions answered inside our booth. We’ve set aside an area where you can speak to our team of experts, from your recent invention to one of our boards. What’s more, you’ll even be able to take home an assortment of Arduino SWAG: stickers, pins and other cool giveaways!

Can’t wait to see everyone soon! In the meantime, stay tuned as we’ll be posting a confirmed agenda of scheduled talks in the next few days. For everything else, check out Maker Faire’s official site!

Draw images and words in falling water

The Base42 team, which is part of the hacking community Tecnoateneu Vilablareixhas created a stunning water curtain with the help of 3D printing and Arduino. The installation, currently on display at the Temps de Flors flower show in Girona, uses 128 3D-printed nozzles and 64 3D-printed valves to dispense water in floral patterns.

The water curtain employs four Arduino Nanos to control the valves, which work in pairs to draw the flowers, words or other images. Meanwhile, an Arduino Mega provides a Wi-Fi connection to issue commands.

In terms of its mechanics, a tank at the base holds 500 liters of water, while a pump pushes that water to the top of the system at a rate of 80 liters per minute. From there, the water passes down through the 3D-printed nozzles, forming what appears as a 3m x 2m fluid screen. To create different patterns in the curtain, the nozzles can quickly adjust the direction of the water to one of two nozzles in a pair.

Bring IoT features to Arduino boards with the Yún Shield!

Great news for Makers working on IoT projects! The Arduino and Genuino Yún Shield — now available on our online store for $49.90/€43.90 — is a device that enables you to easily bring Yún features to Arduino and Genuino boards supporting shields.

It’s the perfect shield to start connecting your projects to the Internet thanks to the Yún Web Panel and the dedicated ”YunFirstConfig” sketch. This new feature, implemented in the new Arduino Software (IDE) 1.6.9, allows you to manage your shield preferences and upload your sketch on the attached Arduino or Genuino. Like the previous Yún board, the Yún Shield uses the Bridge library and extends your board capabilities using the Linux processor.

The new Yún family runs the latest version of OpenWRT (15.05 Chaos Calmer), which offers an additional layer of security and a large amount of bug fixes over previous Yún distribution. The precompiled package list is huge (we have more than 4,000 packages ready to be installed), and if you still can’t find what you are looking for, you can use the community provided repositories since the new release is fully modular (not a fork).

Koka’s Beat Machines are electromechanical instruments

Whereas most musicians would prefer to program their beats on a computer, Koka Nikoladze has elected to take a different approach. The Norway-based violinist/composer/tech developer is the inventor of handmade analog beat making machines that use springs, coils, wood and metal to create sounds.

The instruments — known as Koka’s Beat Machines — are manually programmable to produce different kinds of rhythmic and melodic patterns. The newest member of the family is a bit more electromechanical, featuring an Arduino to amplify the notes and connect the various components inside the device’s wooden housing. There’s also a light on the front that flashes to each unique beat.

You can watch the second of Koka’s Beat Machines in action below.

Sci-fi masks glow to reflect Twitter sustainability trends

Twitter is not only a convenient way to consume daily news and converse with friends online, it has become an excellent platform for gaining insight on what’s important at any particular moment in time. With this in mind, Maker Chadwick John Friedman has decided to harness the social network’s data into web-connected physical representations with the help of Arduino and Temboo.

PrecogNation uses three 3D-printed geometric masks as real-time sci-fi future forecasters, which illuminate and change colors to reflect sustainability trends throughout the world.

The three geometric 3D-printed masks are wirelessly connected to the Internet via an Arduino Yún. The masks were printed using a Zortrax 3D printer and white Z-ABS filament. The masks are a remixed version of Stephen Kongsle’s “Low Poly Mask.” Each mask took approximately 16 hours to print. The masks are constantly scraping data from Twitter in real-time via Temboo Choreos. Temboo assigns special API keys for Arduino devices that allow the user grab real-time data from Twitter that would otherwise be difficult to gather. That live data is then fed to the Arduino Yún, which illuminates a specific 10mm super bright LED, connected to the masks.

One of the largest challenges in representing this overload of data physically was finding the correct terms and/or keywords that activate a specific color/thought in the Precog’s faces. The three colors present in the faces are scraping the Twitterverse for terms relating to sustainability, environmental threats, and political involvement. PrecogNation has its very own Twitter account, which allows the masks to scan through data specifically submitted by sustainability related users, corporations, and initiatives.

As seen in the video below, progress in sustainable development (green) is represented by keywords such as renewable energy, clean coal, water treatment and wind turbines. Threats to sustainability (red) include deforestation, global warming, record heat, extinction, pollution, pandemics and so on. Meanwhile, blue denotes an overload of data and contradicting results.

The overload of data in the color blue works like this… say the word ‘polar’ is found, but then the words ‘melting-polar’ are found, followed by the words ‘polar bear.’ This is an unreadable thread of information – it’s not really giving us threats or progress related to sustainability so the face reflects the color blue to signify that confusion. Coming up with the correct terms to represent the overload of information was especially tricky, and writing the code to reflect that confusion was equally as challenging. I eventually found a series of keywords and demands that elicited the response I was hoping for in this category.

It is important to highlight the fact that although the colors red and blue may be perceived as negative (and usually appear more than the color green), they also mean that there are discussions about those negative sustainability issues happening every time those colors are activated. This is, in fact, a positive outcome, as one of the main goals of this project is to highlight the importance maintaining a dialogue – even if that dialogue surrounds daunting threats to sustainability. It is important that the masks provoke a highlighted continuation of focus surrounding social and political sustainability issues.

Hacked IKEA table “dances” to your favorite music

Your coffee table can have many uses — it rests your drinks (with coasters, of course), stores miscellaneous items, adds some style to your living room, and even serves as the center of a conversation area. Up until now, though, one thing it hasn’t been was a music visualizer. But thanks to this guide from Make: Magazine, you’ll soon be able to start a dance party on demand using your $10 jumbo-sized IKEA side table.

Aside from the inexpensive piece of furniture, the project calls for an LED matrix, tons of lights, a mic, some small electronic components, and an Arduino Uno for its brain. This allows its display to react and “dance” to the tunes coming from your speakers. Since it employs a minimal amount of current, the good news is that you’ll be able to run it off an iPhone charger or any other USB port that’s nearby.

It’s based on the Tiny Music Visualizer project from Adafruit, using their I2C multiplexer board for a tiny 8×8 bicolor LED matrix. The Arduino code is from there, the circuit is from there — all I really created was a big handmade LED matrix, and put it into an IKEA table!

Plug its USB cable into a phone charger or any USB port, then crank up the tunes and enjoy watching the giant tricolor pixels dance like splashing fountains of spectrum analyzer goodness!

If you’re looking for an accessory that’ll be the light of your next shindig, head over to Make:’s full tutorial here. 

Simone Giertz built a hair washing robot

From getting out of bed to applying lipstick to eating breakfast, Simone Giertz has seemingly found every possible way to automate her morning routine. Next on that list? A hair-washing robot made up of a rubber hand, a bottle of shampoo and some basic electronics that allows her to lather, rinse and repeat, while leaving her hands free for other tasks like brushing her teeth.

Giertz’s latest project features a pair of Hitec servo motors, Actobotics from Servocity, an Arduino Uno and a 6V battery pack. Although you’d probably never use this thing in an actual real shower, a shampoo robot is still pretty darn hilarious. See it in action below!

Five students create the perfect grilling thermometer

For those of us who aren’t grill masters, knowing when a piece of meat is done can be quite the challenge. To help ensure they never under or overcook their steaks again, five Rice University students recently developed a seven-sensor grilling thermometer as part of their senior engineering design project.

The team — which goes by the name Five Guys and Ribeyes — considers the Meatmaster to be the perfect barbecue accessory, which will hopefully take the headaches and uncertainties out of grilling.

We are using a food-safe multimaterial sheath primarily made of plastic, but with horizontally placed gold-plated copper casings every quarter inch. Inside each of these casings, we have placed a small thermistor to measure the temperature. The thermistors are wired to a printed circuit board and Arduino, which displays the multiple temperatures on an LCD screen.

When inserted into the meat, the array of sensors will provide a temperature profile throughout the depth of the steak. This will enable error-free grilling.

By using a multimaterial sheath instead of solely stainless steel, the team eliminated any unwanted vertical heat flow along the length of the probe but still allowed for fast heat conduction between the meat and sensor. The probe was 3D-printed using PEEK plastic and holds thermistors enclosed in copper casings along the length of the probe; the thermistors then provide fast, accurate and discrete temperature readings.

So far Five Guys and Ribeyes says the thermometer is working great, and have already received some positive feedback. Although there are no plans to take the Meatmaster to production just yet, the team is looking to make several improvements before it becomes a consumer product. These enhancements include a more efficient power source (currently powered by a 9V battery with a life of six months), additional sensors, wireless connectivity that pushes updates to your phone, an increased temperature range, a decreased settling time and a better material for the probe itself.

Autograph is a machine that creates art using nails and thread

String art is a type of art characterized by an arrangement of thread strung between points to form abstract geometric patterns or representational designs. Thread or wire is wound around a grid of nails hammered onto a wooden board to make unique masterpieces. To expedite the assembly process, London-based studio Laarco has developed a machine capable of ‘printing’ large-scale, gallery-worthy artwork. Autograph uses thousands of nails and a single 500m-long string to construct detailed 40cm x 40cm (16” x 16”) images of celebrities, ranging from David Bowie to Matt Damon to the Beatles. (You can see them all here.)

In terms of hardware, Autograph is equipped with a Raspberry Pi at its core, which sends commands to an Arduino Mega fitted with a 3D printer shield to control the mechanism. The results are absolutely amazing, as you can see in the time-lapse video below.
