Experience sound multi-sensorially with Ocho Tonos

via Arduino Blog

ochotonos

Some of you may have noticed that words like rhythm, texture, pattern, can be used both to describe fabrics, as well as sound. Focused on building an interface as a whole, using mostly textiles, OCHO TONOS invites the user to interact through touch, and experience sound in a multi-sensorial way. Ocho Tonos is an interactive installation by EJTech duo (Esteban de la Torre and Judit Eszter Kárpáti) I met last July during etextile summer camp while they were working on this experimental textile interface for tactile/sonic interaction by means of tangibles:

Exploring the relation between sound and textile and experimenting with the boundaries of our senses whilst changing the way we perceive fabric, surfaces and their manifestation as sound. Recontextualizing our tactile interaction with textile acting as an interface, where each element triggers, affects and modifies the generated sound’s properties. Creating a soundscape through sensor technology enticing audiophiles to interact and explore with reactive textile elements.The nexus of the body, the senses and technology.
OCHO TONOS is a symbiosis of the unique hand-crafted traditional textile techniques and the immaterial digital media.

Thanks to Arduino Mega ADK , all inputs coming from the touch of the user on the soft sensors are translated into a digital platform, parsed and filtered through MaxMSP, in order to control the generation of a soundscape in Ableton Live.

Ocho Tonos was chopped, spiced and cooked at Kitchen Budapest. Sounds used are samples from the working machinery at  TextielLab.

A digital nose detecting air pollution and dust particles

digioxide

After Anywhere, Turbo-gusli and Solaris, Dmitry Morozov shared with us Digioxide, a new interactive work using Arduino Nano, hc-06 bluetooth module, gas and dust sensors, LG mobile printer :

This project aims to raise public awareness of the environmental pollution by artistic means.
Digioxide is a portable wireless device equipped with sensors of air pollution gases and dust particles that is connected to computer via bluetooth. This allows a person with digioxide to freely move around a city, seek out ecologically problematic places and turn their data into digital artworks.

The information about the concentration of dust and harmful gases, such as CO, CO2, HCHO, CH4 and C3H8 and spme others is algorithmically transformed into generative graphics, forming an abstract image. The device’s mobile printer allows instant printing of this air “snapshot” that can be left as an evidence on the place, or given as a present to a passerby.

Experimenting new interfaces for Radios with wood and fabric

via Arduino Blog

experimentalradio

An Interaction and Industrial Designer studying at Carnegie Mellon University in Pittsburgh tried to re-imagine the way we interact with radios to create a more meaningful relationship between the user and the artefact.

Radios have been around since the 1920s but the devices we have at home haven’t changed much even if they were designed nearly 100 years ago and share similar elements like switches, knobs, sliders.

Yaakov Lyubetsky worked on a prototype of The Experimental Form Radio using Arduino Uno:

When The Experimental Form Radio is laying on a tabletop, it is off. To turn the radio on, you pick it up and slot it onto a wall mount. The radio leverages the elastic qualities of fabric to control stations and volume. To change stations you press lightly and slide your finger along the fabric surface. To change the volume you press firmly into the fabric, and then slide your finger along the deeper cavity in the radio. The video below showcases the interaction.

Requiring the user to pick up and wall mount the radio to turn on creates a ritualistic experience with a very simple feedback mechanism. If the radio is hanging on the wall it’s on, if the radio is laying on a flat surface then it’s off. The visual and auditory feedback allows the user to have a clear understanding of the system state.

Even cooler than the video above is the next one, showing all the “Making of” process to build the wooden piece and the soft interface:

The project uses an Arduino Uno board with a custom circuit made with three independent layers of conductive fabric and conductive thread. Touching together two layers of conductive fabric completes one of twelve circuits that then either change the radio station or the volume.

Take a look at the additional documentation on his website.

Wood Lizzie is a DIY Soap Box Cart controlled via Wi-Fi

via Arduino Blog

soapcart

In the following 10-minute video, the Currah team is showing us all the details of Wood Lizzie, a project experimenting with Arduino Mega and Wi-Fi Shield, a very flexible steering system and the virtually unlimited control range afforded by WiFi and Internet Protocol:

The original plan was to construct one of the two-wheeled robots very popular with hobbyists but it was eventually decided that the resulting vehicle would be of very limited application and capable only of traversing smooth surfaces. However, note that the current design can be viewed as the drive of a two-wheeled robot coupled with a trailer by means of a 360 degree pivot. A slip ring capsule within the pivot enables the heavy battery and bulky control system to be separated from the drive and located on the trailer thereby distributing weight evenly between the four wheels.

soapcart-inside

DIY soap-carts were pretty common among kids in the first part of the 20th century and built from old pram wheels, scrap wood and, typically, soap boxes. They could provide a lot of fun for the family at very low cost and in recent years there’s a new interest in them especially to those appreciating their vintage look!

 

GPS lamps and the (in)visible landscape of the networked city

via Arduino Blog

gps-lamps2

Satellite Lamps is a project investigating one of the most important contemporary infrastructures, the Global Positioning System or GPS. It’s a project curated by Einar Sneve Martinussen, Jørn Knutsen and Timo Arnall as part of the Yourban research project at the Oslo School of Architecture and Design and continues their previous work on revealing the materials of technologies that started in 2009 with RFID and Immaterials: Light Painting Wifi. The project uses Arduino extensively, and is also thoroughly documented:

GPS is widely used yet it’s invisible and few of us really have any idea of how it works or how it inhabits our everyday environments. We created a series of Lamps that change brightness according to the accuracy of received GPS signals, and when we photograph them as timelapse films, we start to get a picture of how these signals behave in actual urban spaces.

 

They published a film that you can watch above, and published an article that details very thoroughly how it was made and why. If you are interested in the project, you can read more on how they explored GPS , how the visualisations were made, and about the cultural history of GPS.

gps-lamps

This is a GPS receiver connected to Arduino that sends data to a piece of software running on a laptop. It is a quickly designed tool, a transparent plastic box that that allows us to observe the performance of the electronics, and still mobile enough to carry in hand or a backpack.

ArduinoGemma

Arduino Gemma preview – Final board coming late autumn

During his saturday morning presentation at Maker Faire Rome, Massimo Banzi gave a preview of a new collaboration and a new board: Adafruit Gemma becomes officially Arduino Gemma, a tiny but powerful wearable microcontroller board in a 27mm diameter package.

Powered by an Attiny85 and programmable with the Arduino IDE over USB, anyone will be able to easily create wearable projects with all the advantages of being part of the Arduino family. The board will be default-supported in the Arduino IDE, equipped with an on/off switch and a microUSB connector.

The Attiny85 is a great processor because despite being so small, it has 8K of flash and 5 I/O pins, including analog inputs and PWM ‘analog’ outputs. It was designed with a USB bootloader so you can plug it into any computer and reprogram it over a USB port (it uses 2 of the 5 I/O pins, leaving you with 3). Ideal for small & simple projects sewn with conductive thread, the Arduino Gemma fits the needs of most of entry-level wearable creations including reading sensors and driving addressable LED pixels.
After the fruitful joint effort developing Arduino Micro, once more the Arduino Gemma has been developed in collaboration with Adafruit Industries, one of the main leaders of the Maker movement. Arduino Gemma will be available for purchase on the Arduino Store and Adafruit Industries starting late autumn 2014.

Technical specifications:
Microcontroller: ATtiny85
Operating Voltage: 3.3V
Input Voltage (recommended): 4-16V via battery port
Input Voltage (limits): 3-18V
Digital I/O Pins: 3
PWM Channels: 2

It can be used for multiple applications, not only for music! You can download the Fritzing  and make it yourself on the Instructable and see it in action with this video:

 

Visualizing the unique processes of human brain with magnets and liquids

via Arduino Blog

solaris

Solaris is an interactive installation created by Julia Borovaya (idea curation), Edward Rakhmanov (robotic system, chemistry), Vtol (programming, electronics) with the help of Alexander Kaplan, professor of neurophysiology:

it demonstrates the field influence of the permanent magnet on the magnetic and spirit (fluorescent) liquids. Two liquids constitute the diphasic system. Due to liquids movements and their surfaces’ modifications we visualize the unique processes of human brain. The spectator wears on neuro interface Emotive Epoc, the device computes a brain activity and sends information to the installation machinery.

To test the project people of different ages, social groups and professional areas were invited. Test results confirmed that brain activity and mood of the man reflect on the dynamic and character of liquids movements in the sphere. Object reacts on the changes of mind and emotion states. People who spent a plenty of time with the object managed to influence the dynamic and direction of the liquids on the unconsciousness level. We also reveal that the installation visualizes the temperament of the person. The object copies your mental organization and echoes it on the liquid’s surface. The object becomes a part of the participant.

It runs on Arduino Uno controlling dc motors, 2 actuators and a custom digital motor control system interface.

Bluetooth Thingies at Maker Faire

via Hackaday » » hardware

In case you haven’t noticed, one of the more popular themes for new dev boards is Bluetooth. Slap a Bluetooth 4.0 module on a board, and you really have something: just about every phone out there has it, and the Low Energy label is great for battery-powered Internets of Things.

Most of these boards fall a little short. It’s one thing to throw a Bluetooth module on a board, but building the software to interact with this board is another matter entirely. Revealing Hour Creations is bucking that trend with their Tah board. Basically, it’s your standard Arduino compatible board with a btle module. What they’ve done is add the software for iOS and Android that makes building stuff easy.

Putting Bluetooth on a single board is one thing, but how about putting Bluetooth on everything. SAM Labs showed off their system of things at Maker Faire with LEDs, buttons, fans, motors, sensors, and just about every electrical component you can imagine.

All of these little boards come with a Bluetooth module and a battery. The software for the system is a graphical interface that allows you to draw virtual wires between everything. Connect a button to a LED in the software, and the LED will light up when the button is pressed. Move your mouse around the computer, and the button will turn on a motor when it’s pressed.

There are a few APIs that also come packaged into the programming environment – at the booth, you could open a fridge (filled with cool drinks that didn’t cost five dollars, a surprise for the faire) and it would post a tweet.

Yes, The Drink Up Fountain is talking to you!

via Arduino Blog

drinkupfountain

The Drink Up Fountain is project created in September 2013 by YesYesNo Interactive studio in collaboration with PHA Honorary Chair First Lady Michelle Obama and dedicated to encouraging people to drink more water more often: “You are what you drink, and when you drink water you drink up!”

The Fountain runs on Arduino Mega  and

dispenses entertaining greetings and compliments intended to entice the drinker to continue sipping. When a drinker’s lips touch the water, the fountain “talks,” completing a circuit and activating speakers. When the drinker pulls his or her head away and stops drinking, the circuit breaks and the fountain stops talking. With hidden cameras set up, Drink Up caught unsuspecting individuals using the fountain in New York City’s Brooklyn Bridge Park
