DRM Chair – Chair that self-destructs after 8 uses

DRM_Chair_05 copy

DRM_Chair_05

Created by ECAL‘s past and present students, DRM Chair provides a limited number of use before it self-destructs. A small sensor detects when someone sits and decrements a counter. Every time someone stands up, the chair knocks a number of time to signal how many uses are left. When reaching zero, the self-destruct system is turned on and the structural joints of the chair are melted.

The number of use was set to 8, so everyone could sit down and enjoy a single time the chair. The cast-wax block is embedded with nichrome wire, the sensor made with Arduino counts the people and number 8 is reached the system is turned on.

The project is an entry for thedeconstruction.org and made in 48 hours by Gianfranco Baechtold, Laurent Beirnaert, Pierre Bouvier, Thibault Brevet, Raphaël Constantin, Lionel Dalmazzini, Edina Desboeufs, Arthur Desmet and Thomas Grogan
