GMU:Speculative Atmospheres II/Nicolas Krewer: Difference between revisions

==Concept==

Inspired by the yearly happening Sisyphean task of sweeping leaves and get them blown away again by the wind. In this installation wind is captured outdoors and will be transmitted and reproduced in a hermetic like glass cube right underneath. Four fans are blowing receipts through a space in the direction and the speed from the wind outside. The fans are positioned in the corners to cover the whole room, instead the corners would be left out and paper would get stuck. The receipts are printed with information about the polluted air, which on one hand represent the leaves, but should also address the issue of a senseless environmental pollution.

The use of an Arduino Mega is necessary to provide enough digital inputs that support interrupts, but also enough outputs for the motor controller, the printer and the other sensors. For the fans, brushless motors are used, that are also very common in drones, e-bikes, etc. They are controlled with ESC motor drivers and powered by RC batteries, so the installation can stand independently from a power socket.

For printing the receipts a standard TTL receipt printer is used together with eco friendly receipt paper. (To cut the paper a belt driven slider is built with a stepper motor and a blade attached to a module on the belt.)
