Here is another post about the InfoPanel Spirit, or “how students find ways to communicate through the apropiation of their surrounding Architecture”.
InfoPanel was one of the features in the project for the Student House in Trondheim. It was some sort of communication or socialization device, that, among other features, it would allow students to control their profile inside the community of the Student House.
In this case, an MIT student, Dheera Venkatraman, designed an innovative way to hack his dorm door and enter his room without using a key.
In this version of the door opener (he went through several ones) he completely disassembled an old IBM typewriter and used it to pull the doorknob. This was also accompanied by an LCD display, separated from a laptop and mounted through the door, sending the wires through the hole left after unscrewing the provided eyehole.
The LCD display permitted people to leave messages as well as enter a dialog box that would allow a password to be entered to unlock the door.
This version of the door opener also used a variety of other entry authentication systems, including using a barcode scanner, magnetic reed sensors positioned strategically behind the door (where you would have to tap the correct sequence at the correct place on the door with a strong magnet), and capacitive (where you just tap your fingers on the doorknob itself in a particular pattern).
