Red is an optic-sound electronic object that uses simple light sources and optical elements to create audiovisual performance. The machine was named as a color because at the center of the work there is a red glass crystal and a flexible Fresnel lens. Dmitry Morozov aka :: vtol: : created it using Arduino with pure data and python scripts:

The project includes many reworked electronic devices – a CD-rom, an old scanner, reused electric motors. Multiple moving elements provide wide variability for rather primitive optical elements. It is accomplished by constant change of focal length between the light source, crystal and lens, as well as by changing the crystal’s tilt angle and mechanical distortion of the lens. The object works autonomously, by algorithm with many accidental events tied to feedback, with sensors defining the position of various mechanical elements in relation to the range of their movement. The sound part has up to 4 voices which depend on the activity of various elements. The sound is also in direct interaction with actual position of those elements, and basically is voicing the process of movement, brightness of light, and intensity of the piece.

Stellar is an interactive installation by sound artist Francesco Fabris, which aims to create a sonic representation of stars and constellations through a dedicated interface.

The project has been developed using two Arduino Uno, LeapMotion and Max7 software managing data of more than 300 stars and 44 constellations, stored from the open-source software Stellarium, and coded to interact with the robotic arms.

One Arduino Uno board controls four servo motors and a second one controls the led stripes. The motors are controlled with two LeapMotion but since LeapMotion doesn’t support two devices on one computer, he used two miniMac  connected through an Ethernet network.

Since there’s no sound in space, Francesco wanted  to conceptualize a link between electromagnetic and sound waves  to create a minimalistic, interactive device which would allow visitors to learn about specific stars through sound information:

The base of the system is a cylindrical structure, on top of which are displayed the most important constellations of the northern sky. Above this representation are two robotic arms. When the tip of one of the arms aligns with a star, information on the selected star is transformed into simple sine waves, changing the colour the star emanates.

Two players can use the system at the same time, by moving their right hands over the two black, circular sensors. This allows them to move the robotic arm both horizontally and vertically.
The data analyzed for each star are: temperature (color index: red star = old and cold, blue star = hot and young), brightness (as seen from Earth), distance (from Earth) respectively transformed into: frequency (Hz), amplitude (dB), duration (ms).
The colder the star, the lower the pitch; the brighter it appears to us from Earth, the louder the sound; the further from Earth, the longer the duration.
For example, a bright, red star four thousands light years from the Earth would generate a low frequency, loud and long sound. A blue star which is closer to the Earth would generate a high frequency, weaker and shorter sound.

The background drone-sound is white noise (which is a combination of all frequencies, the opposite of space-silence). When a constellation is triggered, the number representing its area (squared degrees), becomes the cutoff frequency of a low-pass filter for the noise signal. In this way, larger constellations will gradually increase their frequency.

Stellar has been produced with the support of the DE.MO./MOVIN’UP I Session 2015 project, and promoted by the Ministry of Cultural Heritage & Activities & Tourism, General Directorate for Contemporary Art, Architecture and Urban Suburbs and GAI – Association for the Circuit of the Young Italian Artists.

Photosynthesis is an interactive installation for primary school children created, designed and developed by Moritz von Burkersroda and exhibited at P3 Ambika, University of Westminster.

It’s a  learning  experience to understand the abstract process of photosynthesis in a hands-on way.  Thanks to a physical interaction  kids can easily understand what  plants convert light into chemical energy to fuel their activities.

The installation uses an Arduino to measure data from a photoresistor and a hacked Wii-remote to connect the objects with the video feedback on the screen triggered by a Processing sketch. On the page of the project you can download a Design Research Document about Contextual study theory to understand the relationship between interactivity, learning and educational institutions, like museums.

Wing is an interactive installation created by Dmitry Morozov  and commissioned by the Center for Art and Media (ZKM) in Karlsruhe, special for GLOBALE: Exo-Evolution exhibition, 2015. It’s a 2,5-meter wing that can be flapped by visitors thanks to compact dermal myLeaographic sensors (sensors measuring the electrical potential of muscles) installed  behind their ears and connected to an Arduino Uno:

The main idea of the project is an ironical and at the same time serious research on the topic of development of new instruments and prostheses as “extensions” of human body and accordingly its possibilities and potentials, which are being revealed by new technologies. At the same time, it’s an attempt to stimulate people to perceive and train the body in a different way, expanding the limits of self-control and self-organisation in order to adapt to the new conditions. At the same time, just like many spiritual practices aiming at the elevation of human soul through deep relaxation and control over seemingly uncontrollable muscles, this project uses the metaphor of flying as a reward for the ability to direct your mind to solving of non-standard tasks.

“The color Visualizer” is an immersive installation to understand how color is used in nature to communicate between living organisms and to explore biodiversity through the lens of color:

By plucking an array of multi-colored strings, which are layered over the large array of high resolution screens, visitors can explore over 100 unique color stories as vibrant images and short videos appear before them. Strum a red cord, for example, and learn how a male cardinal bird colors his vibrant red feathers with pigments from food; strum a yellow cord and see how a yellow leopard’s spotted coat allows this predator to blend in with shadow and light while moving through tall grass.

The eye-catching cylindrical installation is part of the permanent exhibition “The color of Life” that opened in June 2015 and was created by Tellart in collaboration with the California Academy of Sciences. It was prototyped using Arduino Uno and it’s currently shortlisted for the Interaction Awards, representing excellence in interaction design.

In the video below the team working at the project explain the main features of the educational installation and show a bit of the making of:

Team Game is an interactive installation to reflect about video games and controllers made by Caroline Buttet. It runs on an Arduino Uno or Genuino Uno controlling a flex sensor, a custom made potentiometer, and a light sensor with the help of Unity software and Uniduino plugin:

It’s a simple game in which you need to roll a ball from one side to another of the screen. The trick is, you need some custom controllers to play. And you also need 2 partners that will play with you so that you can progress through the 3 levels. Rather than playing against the others, you will have to team up in order to win!

Happy Days is an installation inspired by the work of the Irish avant-garde novelist Samuel Beckett who wrote the namesake play in two acts in the 60s. Designer and visual artist Irena Kukric created it in collaboration with Canny Sutanto and the aim of exploring narrative in the form of an installation. The five-minute play is staged using ten servo motors and a DC motor with an Arduino Mega and VVVV live programming environment:

We were beginners with Arduino and motors so we started out pretty basic, trying to move several motors at once. We decided to use VVVV platform in addition when we realized we needed a timeline for our script for the play. With this timeline, it was easier to deal with details such as when we want to move which motor under which angle and such. For beginners with coding, this visual programming environment is very approachable and the entrance level is much lower.

It is easier and faster to get to your desired outcome. What is great about VVVV and Arduino is that there is the Firmata library that enables you to work with both platforms in conjunction so even artists and designers with lower level coding skills are able to go from concept to realization quite easy. We used Arduino Mega which was very convenient considering the number of our motors and the pins that Mega has to offer. After we had our final order of cables and pins, we even made our own shield for it.

The play was staged without human actors or conventional (verbal) dialogue  as performing a ritual in the play overshadows the performer, the object of the ritual can survive on its own. Therefore, they used these objects or rather props from the play and made them actors, animating them with motors, as you can see in the video below:

There’s a mineral called pyrite with a interesting nickname, fool’s gold, because it has a superficial resemblance to gold and it’s by far the most frequently mineral mistaken for gold. Even if it’s pretty abundant, there’s a rare form of pyrite which is crystallised in radial shape (as unusual disc spherulites), taking the shape of a disc. The amazing fact is that the only deposit where pyrites of such morphology are found is in Illinois (USA) and the discs are dated around 300 million years ago!

Dmitry Morozov (aka ::vtol::), a media artist living in Moscow, had the chance to use a pyrite disc and created Ra,  a sound object / synthesizer running on Arduino Nano. Ra uses laser for scanning the irregularities of the surface of the disc and further transforms this data to produce sound:

This project originated as a result of an interesting set of circumstances – a pyrite disc was given to me as a gift by a mineral seller in Boulder city (USA). Upon hearing about my works, she asked to do something with such crystal, and refused to take payment for getting it. In the same period, I was reading articles on various ways of archiving and preservation of sounds from the first, historical sources of the recorded sound – wax discs and other fragile carriers. All technologies were based on the usage of lasers. Inspired by these projects, I set out to create a self-made laser sound reader which would be able to produce sound from various uneven surfaces, using minimal resources to achive it. Thus emerged the idea to construct an instrument using the pyrite disc and a self-made laser sound reader.

The production of the object was possible thanks to the commission of the Sound Museum in St.-Petersburg which now has Ra in its collection.
