Russell Grokett has taken a Raspberry Pi and fed in data from the USGS (United States Geological Survey). He has then put a box around the Pi and added an LCD screen and some motors. When an earthquake is detected, the LCD displays information about the quake and the box buzzes/rattles in relation to the magnitude of the disturbance. It’s a lovely project and he’s written the whole thing up here. All the code is available here for you to create your very own earthquake monitor.
