An early warning device of earthquakes (and other maladies) for everyone

Summary In October 2013, I built a prototype earthquake early warning (EEW) device, for less than $110 in parts, for my house that taps into the California ShakeAlert system. In the recent 6.0 magnitude quake centered near Napa, we got about 5 seconds warning here at my home in Berkeley, CA before the shaking began. Such devices could (and should) be mass produced, sold as ubiquitously as fire alarms or carbon monoxide detectors at a similar price point and installed with as little friction.
