Planet Arduino

Give kids some responsible and challenging tasks, and you’d be surprised at the results. The “Anything Goes” exhibit at the National Museum in Warsaw was aimed as a museological and educational experiment. A group of 69 children aged 6–14 was divided into teams responsible for preparing the main temporary exhibition at the museum. Over six months, they worked on preparing the exhibition during weekly four-hour meetings. They prepared scripts, provided ideas for multimedia presentations, and curated almost 300 works for display. One of those was [Robert Mordzon]’s Giant Interactive Crossword.

The build is in two parts. The letter tiles, which have embedded RFID tags, obviously look like the easiest part of the build. The table, looking at the video (after the break), probably needed a lot more effort and labour. It is built in two halves to make construction easier. There are a 130 boxes that need to be filled in with the right letters to complete the crossword. Each box contains a bunch of electronics consisting of an Arduino Nano, a RFID Reader and a bunch of sixteen WS2812B LEDs, all assembled on a custom PCB. Do the math, and you’ll figure out that there’s 2080 LEDs, each capable of sipping 60 mA at full brightness. That’s a total current requirement of almost 125 amps at 5 V. Add in all the Arduino’s, and [Robert] needed a beefy 750 W of power, supplied via four switch mode power supplies.

Each Arduino Nano is a slave on the I²C bus. The I²C master is an Arduino Mega 2560, which in turn communicates with a computer over serial. When a box is empty, the LEDs are dim, when a wrong letter is placed, they turn Red, and when the right letter is placed, they turn Green. If a word gets completed, a special word animation is played. This information is also passed on to the computer, which then projects an animation related to the word on a giant wall screen. Upon the crossword getting completed, the table erupts in to a sound (via the computer) and light “disco” show and also reveals the main motto of this section of the exhibit – “Playing the Hero”.

Thursday May 28th at noon The Computer History Museum is hosting an open lecture by Massimo Banzi, co-founder of the Arduino project. He will cover the historical origins of Arduino, including discussion of the process of designing tools which make digital technology accessible to people who are not experts, and the essential role of the larger Arduino ecosystem that supports this remarkable computer platform.

The Computer History Museum, located in Mountain View (California), is a nonprofit organization  exploring the history of computing and its ongoing impact on society in the last 40 years. The Museum is dedicated to the preservation and celebration of computer history, it hosts the largest international collection of computing artifacts in the world and many virtual exhibition you can explore directly online.

If you like vintage images and history of computing, check the “visible storage” collection below.

The main image of this post is a picture by Massimo Banzi showing the first useable Arduino prototype. Still called “Wiring Lite”, used as a low cost module for wiring users. David Cuartielles joined at this point (the flying resistor is his first contribution to the design) from this point on the project becomes Arduino. 

Visual artist and filmmaker Tyler Tekatch worked with Kyle Duffield, interactive programmer to create an interactive video installation called Terrors of the breakfast table, currently on view at the Art Gallery of Hamilton in Ontario, Canada, until May 25 2014:

The visitor approaches a table and chair in the centre of the space, and blows into a sculptural device on the table, when the device glows orange. Subtle technologies sense the viewer’s breath, triggering thought-provoking interactive elements, such as a dream montage, the pace of a scene, the ambient sound, and the brightness of the visuals. The viewer discovers the interactions at their own pace, and some of the effects are more subtle than others.

They used a combination of cameras to shoot the project, including the Canon C100, the 5d markiii, and the Sony FS700 to achieve some of the super slow motion shots. The film was edited in FCP7, graded in DaVinci Resolve, and effects were done with Cinema 4d and 3ds Max.

For the interactive elements, they used Max 6 for all of the programming, including the Arduino library, AHarker Externals library, Ambisonics Externals from ICST, and externals from Jamoma. They experimented with a number of different approaches to the sensor, including sound analysis, but finally settled on an anemometer designed especially for breath by the company Modern Device.

The sensor was paired with an Arduino Uno,  to which they also added LEDs in order to illuminate the sensor housing sculpture, and which were also mapped to the viewer’s breathe.

The weekly post on the Arduino Micro,  made in collaboration with Adafruit, is dedicated to an installation for kids made by Scott Garner, a designer, developer and craftsman:

Reach is a large-scale interactive mural and musical instrument created for the Children’s Museum of Pittsburgh as part of the Tough Art residency program. There are no visible electronics, but when users touch both the moon and a star (either alone or by holding hands with others) a tone is played.

The Arduino sketch and PureData patch are viewable on GitHub and below you can watch an inspiring video of the “Making of”:

Codebreaker is the exhibition started last year at  the Science Museum of London and celebrating  the centenary of the birth of computing pioneer Alan Turing.

Hirsch&Mann were commissioned to create a “series of exhibits which demonstrated and recognized the progress in computing while at the same time representing a spirit of engineering and innovation” .

They created three installations that demonstrated 3 programming principles:

LOOPING: A spinning rotor with LEDs on it -> creating POV patterns all controlled by 30 arcade style illuminated switches.

CONDITIONALS: A version of Wolfram’s cellular automata – user was able to choose the result of the child node once the parent node conditions were met

VARIABLES: A mechanical tree – the branch angles were controlled by sliders on the console. Slider A controlled 1 angles at the base of the tree, slider 2 controlled the next 2 angles, slider 3, the next 4 angles and slider 4 the final 8 sliders.

Each installation has a light box which is revealed as soon as you press the BIG GLOWING button on the console. This turns on the lightbox – which has simplified pseudo code and essentially allows people to “step into” the code. Each line that is currently running is highlighted and then you see the result on the installation.

The whole point of these installations was to show where we have come since Turing’s time and stepping on his shoulders.

If you have the chance to visit the exhibition (it’s free!) or watch the video below you will see that at the center of each console there is an Arduino UNO.
