Dorkbot 1 Barça 0

This is the first time that it happens. That one of our meetings fell the same day that a Barça match… But somehow it had to occur. We hope that you won’t get lazy and attend the next Dorkbot event. This springtime we present wireless systems that allow to control devices with brain waves, interactive installations that are a metaphor of the 21st Century, Thermins made out of old AM radios (exactly like the ones that  grandpa uses to hear the football match) and MIDI violins. As usual the meeting will take place in Hangar and if you can’t make it or you are in a land further away, you can always connect to the event via Streaming.


Starlab present Enobio. More than one of us has dreamt of controlling the computer with just a glance… you might think that I am telling you the argument of a science fiction movie. Well…not. The future is here. Enobio is a wireless system capable of capturing brain waves, heart beats, eye movements and muscular activity in real time. From here everything is possible, countless multimedia aplications can be implemented where the user and the creative process are closely connecteed. The Starlab team will demonstrate some of the possibilities of the system such as control of MIDI instruments, generation of OSC commands, interaction with multimedia software and direct sonification. The creators of Enobio are the Starlab Team Starlab define themselves as customer oriented scientists, they are a group of international scientists, engineers and economists who aim for a positive impact of technology in the society and the planet, to squeeze everything they can out of the possibilities of science.

Joan Vallvé

Joan Vallvé has recently made an artist in residence in Hangar, where he has done a small part of what is his project: Developing an automatic creation environment for a musician. In this first stage he has built various automatizations that become MIDI instruments, like for instance, the violin, that he is going to present us, an instrument specially created for live performance, light and desarmable and with live performing and sequencing possibilities.

Can robotics bé reflective? Can an interactive piece become a metaphor of the 21st Century? Of Course! because “Alienated Routine” represents the process that the society is being through in these days and age, using semiotic symbols and alienated movements.
“Alienated Routine” is a suspended robotic sculpture connected to a circular animation, in which the presence of the users activates the routines of the piece. It is an sculpture with a shape that reminds the form of six unified fingers that represent mankind, the connected animation is the city of the 21st century and its sympthoms and the user that activates the routines represents power.
This project is funded by the MIS (Museum of Image and Sound) in Sao Paulo and has been developed in Hangar’s Medialab

David Sarsanedas i Esteve Farrès

For Esteve Farrés and David Sarsanedas the limit when it comes to invent and build musical and audiovisual instruments is their own imagination, because they take the best of all the possibilities musical and audiovisual that technology has to offer, no matter digital or analogic. They are going to present a range Do it Youself instruments and clean and simple solutions to perform video tracking.
Esteve Farrés is a Physicist and an Electronic Engineer. David Sarsanedas is a member of L’Orchestra Fireluche and L’Orquestra dels Luthiers Drapaires and DUDU.

They present some projects.


Tube Organ distance activated.
Sandra is an electroacoustic organ consisting of twelve birch wooden tubes, chromatic and poliphonic, that are distance activated thanks to twelve digital sensors. Built in 2007 in collaboration with the luthier Sedo Garcia. Each tube has in its end a michropone and a loudspeaker. The microphone, when being activated, catches the surrounding sound through a small amplifier that sends the sound to its corresponding loudspeaker. That triggers a loop and the sound generates feedback. The tuning of the note is made from the influence that makes the measure of the tubes when they have to determinate the resonance frequency of the feedback that is produced between the microphones and the loudspeakers.
Theremin with AM radios

On the internet there can be found a great variety of schemes that allow to build different types of Theremin. One of these schemes is about building the instrument using the effect of the local oscillators and the superheterodine filter of three conventional AM radios. The project presents a couple of problems, the sound is very unstable, and there is constant presence of parasite voices and music that come from the transmitters that are used. What they have done to solve this is incorporating to the project an Arduino code that turns the board into a small transmitter that emits silence very loud. Thus the stability and the sound quality are considerably enhanced.

Camera obscura analogic tracking

Artificial vision issues have always been related with very complex software codes and the dificulty to control light variations that affect the space that its going to be monitored. This project shows how from a camera obscura (device that is being known at least from the Renaissance era), some photoresistances and a simple Arduino patch, we can get an analogic tracking mechanism that in spite of its obvious limitations, can offer simple and balanced solutions to different projects that require to establish the location of a person or their movement inside a particular space
