Created by Hélène Portier at ECAL, 20°C is a collection of devices designed to question our relationship to data through a series of physical challenges that enable/disable access.
“Information is accessible anywhere anytime. Through our daily actions, we use the network on an unlimited and unhindered basis. We store our data on the network immediately and without storage constraints. For most people, the Internet is elusive and invisible. For the Web giants, the network shall consist of huge data centers, submarine cables and coal mines.”
The “mill” object questions our maintenance and the archiving of our data. How would our daily life be if we had to care for and feed continuously our data in order to preserve them? The system requires the user to maintain a flow of water so that the wheel rotates continuously. When the mill stops rotating, the photos get deleted one by one, second to second. To be able to detect if the wheel is rotating, a hall sensor is used to detect the rotation frequency of 4 magnets arranged around the wheel. Then the custom mobile app delete photos stored on the cloud if the recorded value is negative.
Finally, the user needs to blow on the wind spinner in order to create the necessary energy to send a phone message. The message is only sent when the user blow on the wind spinner. The longer is the message, the longer the user has to blow. The wind spinner is fixed on a small motor, so when the user blow on it the motor create power. This power is send through a jack plug directly connected to the smartphone. Thanks to the custom mobile app, the value
of the audio level from de jack plug is get and used for the progress cursor and the send condition.
