This was a project to control large numbers of remote devices, using a low cost programmable FM broadcast receiver. The system consists of a programmable FM receiver which can decode audio control tones and RDS commands sent from a central FM transmitter, a low power RDS FM transmitter is being planned as a parallel project.
On the 1st of September 2012, Linzer Klangwolke took place in a way never seen before. Taking participation as its basis, Klangwolke brought together the whole city in a one-hour event by enabling them active contributors of the show.
In the preceding two months, more than 500 people had been working to realize this whole-city event, and about 2000 people attended workshops in Ars Electronica, where they built cardboard letters and decorated them in a way that represented their characters. These letters each embodied LEDs connected to the network that would light up based in the signal they were receiving.
The exquisiteness of letters in this context was formed due to two facts:
First, a letter represents the minimum carries in the human language and script. However, the letter itself is not enough, you need a second person, or even a crowd, or a network of people to join, in order to propose a message. This basis provided the nature of collaboration within people.
The second property was the characterization: In the workshops, people were provided with different decoration materials like colored paper, buttons, plastic sheets, ribbons… This way, a creative space was opened up, much like creating your profile in a social network: You would find your letter and then start beautifying it. You would give it a character.
In the end, an original mean of self-expression was born. Then, the challenge was how to connect five thousand LED equipped letters to the network. This was exactly the point how LinzerSchnitte was born.
