A tangible orchestra one can walk through and play with others

Tangible Orchestra is a project by Picarøøn, a collaboration of artists Rebecca Gischel and Sebastian Walter, combining electronic and classical music perceived very individually in a three-dimensional space.

Single units are triggered by people in close proximity and play a unique instrument, with the collection of individual instruments gathering as people congregate in the project space, eventually creating a complete musical work. As electronic music is usually composed and arranged at the mixing desk, the installation creates the illusion of an orchestra playing a musical piece that relies heavily on digitally created sounds and therefore could normally not be perceived this way.

Tangible Orchestra consists of seven individual cylinders that play their unique instrument if people in close proximity are identified by a complex system of sensors. Each column is an independent, interactive sound and computer unit that has the ability to play a separate instrumental track and a sensory system which reacts dynamically to the proximity of its participants.

Essentially, this enables each member of the audience to become a musician and together they constitute a musical ensemble or orchestra. This is achieved because depending on the proximity of each participant to any particular cylinder and the number of participants involved, the range, contribution and volume of the music contained within each cylinder varies proportionately. Therefore, the experience is guaranteed to be different every time; orchestrated by the participants both individually and as part of an ensemble.

The installation uses 112 ultrasonic sensors controlled by Arduino Mega and only if  enough people gather and scatter evenly across the project space, the installation evolves to its greatest potential and the complete work of art can be perceived:

Human interaction within Tangible Orchestra is made possible by 16 ultrasonic sensors on the inside of each cylinder, granting a 360 degree field of view. The sensors are run by one integrated microprocessor per cylinder, evaluating and comparing the readings of all sensors making very accurate assessments.
To avoid interference between ultra sonic waves of different cylinders, the microprocessors run consecutively rather than simultaneously. All microprocessors are controlled, assessed and coordinated by one Arduino Mega.
The programming language Processing is used to communicate with Arduino and consequently with the microprocessors in each cylinder. It is programmed to coordinate the microprocessors, so that their sensors cast their rays consecutively as with 112 ultrasonic sensors operating at the same time, there would be a substantial risk of interference and acoustic shadow misreading. It also assesses the data coming from Arduino and, after verification, generates the output. Is a person detected within the bubble of a cylinder, Processing receives the digital information as an input from Arduino and stops muting the respective instrument which then joins into the melody. Processing also reads the values of each instrumental track to calculate the digital signals for the LEDs and controls the LED stripes inside of the cylinder.
Each instrument is played by a separate speaker which is located in the base of each cylinder. Multiple sound outputs were realised by using several external sound cards together with the minim library by Damien Di Fede. When an instrument plays, the beats of the audible track are analysed and consequently values are calculated to create an equalizer-like light beam. The outcome is transferred via Arduino to a transformer, which converts the 5V Arduino signal into an 230V output operating 192 LEDs per cylinder. Another transformer converts 5V Arduino signals into 12V output powering LED stripes inside of each cylinder as soon as they are activated.

The first exhibition of the Tangible Orchestra was at Royal Mile, Edinburgh  this May 2014. Check their website for next events.

HummingBird Duo is an Arduino At Heart Robotics Kit for Ages 10 to 110

Today we want to introduce you to a new Arduino at Heart Partner launching on Kickstarter this week: Hummingbird Duo is an electronics kit designed to be fun and educational for a fourth grader, a high school student, a college engineering student, or an adult maker.

Hummingbird Duo  creates a bridge between making and classroom education combining craft materials, electronic components and drag &drop programming. Part of Hummingbird’s mission is, in fact, to explode common conceptions of how robotics can be used in K-12 education:

 We have designed several levels of learning into the Hummingbird experience. Instead of a steep learning curve, learners go up a staircase where each step increases skills and where mastering each step allows one to use the Hummingbird in a new and more interesting way.

 

The kit was developed by BirdBrain Technologies, a Pittsburgh, PA firm founded by Tom Lauwers in 2010 to commercialize educational technology developed by the Carnegie Mellon Robotics Institute’s CREATE lab and since 2012, they have pledged 1% of their net profits to the Computer Science Teacher’s Association.

Support them on Kickstarter!

 

 

Museum for all: a tactile exhibition and project from Minsk

Gleb Kanunnikau is  a designer and trainer based in Minsk. He is part of a group of volunteers running a meetup group and an open laboratory bringing together people from the tech and education/media and experimental, hackerspace scene trying to solve a few very local and very practical problems that don’t seem to be getting a lot of attention from the tech community.  Their initiative is focused on providing educational tools for children and adults with vision disabilities and is organized as an open laboratory with contribution from Minsk hackerspace (the first in Belarus), Belarusian meetup.by community, and monogroup.by - community of architects and visual artists.

Gleb wrote me a long email and explained the aims and the context of their amazing work:

The problem is that schools for the visually impaired aren’t getting new books with Braille type and the education system for these kids is stuck in the 1970s, only now it is much worse (at least in the USSR there were factories and employment options for these people, as well as city districts with disabilities-friendly housing). They are the forgotten, invisible people – no textbooks means there are few people able to read Braille books – and they just can’t leave their apartments nor get education or a job.

Luckily, Ludmila Skradal, who works with these children on a regular basis as a tour guide and a teacher, had met a few architects, as well as people from the first Belrusian hackerspace and we’ve organized a hackathon a year ago.

We are building the first tactile museum exhibition for these children (but also for adults) on history/ethnography/architecture.

This is a sound/tactile installation that uses technology but isn’t tech-centric and solves a practical problem. We are combining hand-built architectural plastic models of buildings and elements printed with a 3d printer (open source mendel prusa, with Arduino inside) for small-scale columns and ornaments etc.

The models serve as instructional materials and partly substitute for the missing handbooks on history and culture that the children in schools for the visually impaired are not receiving currently.
The kids say that these architecture lessons were the first time they’ve been able to even imagine what buildings in cities “look like” above ground level. Things that were outside of their reach, like the clock tower on the city hall building, rooftops, column capitals were suddenly accessible – they were invited to touch the real city hall walls during the field trip to feel their texture and then they explored the model, and hearing the sound of the real city hall clock they examined it in the model.

The current goal is to build a museum exhibition unified by narrative and allowing self-exploration within the space, using Arduino for controlling the exhibits.

We hope that 3d printed objects could work as handbooks on history, culture, art. Maybe we’ll even print DNA segments that can be combined as like lego puzzles – so that kids can try to put together a DNA chain out of aminoacid plastic blocks to understand how the spiral of amino-acids looks like. There are many possibilities.

LED Clock Looks Cool AND Tells Time

Clocks have taken many forms of the years, starting with shadow clocks and sundials in Egypt around 3500 BC. Obviously, these could only tell the time while the sun was out. Water Clocks followed which could track time in the dark. Water Clocks are basically a bowl with a hole in the bottom. This bowl was set in a container filled with water. The water entered the bowl at a consistent rate and graduations on the inside of the bowl showed how much time had passed.

Mechanical clocks followed, as did quartz and the atomic clock. We have now entered a new era in time-telling, the Bamboo LED Clock. [Pascal] brings us this funky fresh chronometer all the way from Germany.

The front face is made from a bamboo pizza plate and gives the clock some modern minimalist pizzazz. A 1-meter long LED strip is attached to the circumference of the plate and contains 60 individually assignable RGB LED’s. An Arduino and Real Time Clock are responsible for the time keeping and coordination of the LED’s.

As you can see in the photo, 2 of the LED’s colors are used. The single red LED indicates the hour. The strip of blue LED’s show the minutes. If you’d like to build one of these [Pascal] has shared the Arduino code on his Instructables page.

Introducing The Arduino Zero

The Arduino Uno is the old standby of the Arduino world, with the Arduino Due picking up where the Mega left off. The Arduino Tre is a pretty cool piece of kit combining a Linux system with the Arduino pinout. Care to take a guess at what the next Arduino board will be called? The Arduino Zero, obviously.

The Arduino Zero uses an Atmel ARM Cortex-M0+ for 256kB of Flash and 32k of RAM. The board supports Atmel’s Embedded Debugger, finally giving the smaller Arduino boards debugging support.

The chip powering the Zero features six communications modules, configurable as a UART, I2C, or SPI. USB device and host are also implemented on the chip, but there’s no word in the official word if USB host will be available. There are two USB connectors on the board, though.

The Arduino folk will be demoing the Zero at the Bay Area Maker Faire this weekend. Hackaday will have boots on the ground there, so we’ll try to get a more detailed report including pricing and availability then.

There’s a new Arduino At Heart: littleBits Arduino Module!

We are excited to announce that littleBits joined the Arduino At Heart Program to easily incorporate programming into littleBits circuits!

littleBits Arduino Module is everything you know and love about Arduino without the breadboarding, soldering or wiring.  littleBits takes care of the electronics, while you focus on the code.

The new littleBits Arduino Module allows to:

• Create code using the Arduino programming environment
• Communicate with software (Processing, MaxMSP, Flash etc…)
• Play with 3 inputs and 3 outputs using littleBits bitSnap™ magnetic connector as well as additional I/O for advanced hardware interaction
• Getting started with 10 sketches, including Analog Pong, Tone Libraries and more!
• Access to Arduino AND littleBits community support

Inventing on this platform requires the user to be able to debug through electronics issues as well as software bugs.
For example, instead of having to solder together a complete circuit of power, ground, resistors and LEDs, a user can simply snap a power and an LED module to the Arduino module and dive straight into programming. This will make hardware innovation even more friendly for beginners, and further lower the entry to physical computation.

Take a look at the video and discover what  you could do with it!
