Ed Rogers lives next to active train tracks, which leads to a lot of noise in his bedroom when a train passes and the windows are open. Like any good maker, Ed solved his problem with a homebrew automatic window closer. He attached a pair of linear actuators to the windows with 3D printed brackets. These actuators are controlled by an Arduino with an H bridge and can be activated by a button on his nightstand. Not only that, but the project also integrates a motion detection system to close the windows automatically when a train is passing. At the end of the video, you can see the motion detection system spotting a train and closing the windows. It’s remarkable how much the noise is reduced when the windows are closed. I wonder, what’s the best way to get the windows to close right before the train comes? Any ideas, MAKE readers? [via Neatorama]
