Cooking Hacks at the Sónar 2015June 23, 2015

Cooking Hacks was part of the recent Sónar Festival 2015 in Barcelona. Sónar is a three-day long electronic music festival that was founded in 1994, and has since evolved into a multi-themed event that includes all kind of artistic performances and multimedia exhibitions, enhancing creativity and technology.

It is divided into Sónar by Day and Sónar by Night and, unlike most summer festivals, it does not take place in a field. Sónar by Day is located in the city centre (Fira Montjuïc), and apart from concerts and dj's it hosts showcases and expositions, and the Sónar+D, an international conference focused on creativity and technology, and the digital transformation of the cultural industries involved. It gathers not only artists but entrepreneurs, researchers and companies seeking to integrate music, technology and business.

Watch below the intro video for the Sónar+D.

Sónar by Night is located at Fira Gran Via de L'Hospitalet, far away from the city centre, with most part of the live shows and dj sets until late at night.

Libelium attended Sónar with "Sensors for the Next Generation of Artists", a demo of some of our products and the projects explained below, and participated in the "European Commission: Open Digital Science and Art Workshop", which featured representatives from principal institutions involved in research, art, technology and culture.

Zero Calories Can Dispenser

So this is what we brought to the table. This project is a mind controlled fridge, so you can get a cool drink without physical interaction. A mindwave sensor measures brainwave signals and monitors the attention level of the user. This sensor uses the Bluetooth module PRO from CH to send the data to an Arduino Uno board.

The Can Dispenser is controlled with the Arduino Uno, which collects the data from the Mindwave and displays your concentration levels in an LCD screen and an analogic gauge meter. So all this means that when you concentrate hard enough you get your drink: Inside the covering there is a thermoelectric cooling that uses the Peltier effect together with a fan to create a flow of fresh air.

Partymeter

This application could turn out to be really useful in a festival like this one. Build once again around an Arduino Uno, it is actually a portable medical station for measuring Galvanic Skin Response (sweating) and Pulse and Oxygen in Blood (SPO2):

  • Galvanic Skin Response Sensor (GSR - Sweating): Skin conductance, also known as Galvanic Skin Response (GSR) is a method of measuring the electrical conductance of the skin, which varies with its moisture level. Skin conductance is used as an indicator of psychological or physiological arousal.
  • Pulse and Oxygen in Blood Sensor (SPO2): Pulse oximetry is a noninvasive method of indicating the arterial saturation of functional hemoglobin. Oxygen saturation is defined as the measurement of the amount of Oxygen dissolved in blood, based on the detection of Hemoglobin and Deoxyhemoglobin.

The Arduino Board reads the data from the sensors and sends it to the printer with our RS-232 Serial/Modbus Module. This module allows to connect console ports and special purpose equipment. So, in the end you will get a ticket from the printer with the measured levels and depending on them it automatically assigns you a party level: relaxed, normal, semi-altered, altered or super-altered.

The Partymeter makes use of the e-Health Sensor Shield, a board by Cooking Hacks that allows Arduino and Raspberry Pi users to perform biometric and medical applications where body monitoring is needed by using 9 different sensors.

Radioactive Percussion

Radioactive Percussion

This project was developed by Cooking Hacks and it converts ambient radioactivity in a musical rhythm.

It detects radiation with a Geiger-Müller tube, a type of particle detector that measures ionizing radiation. It is able to detect the emission of nuclear radiation, including alpha particles, beta particles and gamma rays.

The Geiger Counter is integrated in the Radiation Sensor Board. This board is compatible with any tube that works in the range of 400V - 1000V and, in this case, is mounted on an Arduino Uno, but it is also compatible with Raspberry Pi and Intel Galileo.

It has 5 LEDs and an LCD to indicate radiation levels and a piezo speaker that allows to hear the typical "chirp" in radioactivity counters.

To quickly detect increases in radiation levels we use a Vaseline glass bead. This is a safe way to test your Geiger Counter: Vaseline glass contains a small amount of Uranium (less than 0.2%) so it is slightly radioactive but completely safe to handle.

The Arduino and the Radiation Sensor Board are placed inside a covering, so put some Vaseline glass bead next to it and the music starts to play.

We are very much looking forward to the next edition of this festival. We'll see you there!
