When an earthquake strikes, can you feel the earth move under your feet? That depends on how sensitive you are, how strong the quake is, how much everything shakes, and whether or not your Mac is a seismograph.
Shake Your Mac Booty
Recent MacBook models come with a few built-in features that we don’t think about, until someone comes along with an idea. Apple built-in a Sudden Motion Sensor (SMS) to MacBook and MacBook Pro models. With the right app, your Mac becomes a seismograph.
SeisMac is a seismograph app for your Mac. It uses SMS to record and graph vibrations.
With SeisMac running on your SMS equipped Mac notebook, you can watch the seismograph in real time, even while sitting on a dining room table. The SMS feature on your Mac is sufficiently sensitive that it can record your heartbeat, or simple movements.
That includes earthquakes.
A companion app called SeisMaCalibrate can be used to calibrate your Mac’s Sudden Motion Sensors.
SeisMac has a range of plus or minus two gravities of acceleration and displays 256 values per gravity, up to 500 times for each of three axis. What you get is a real-time display of vibrations, including that of earthquake tremors.
The graphs and data are nice, but I’d like to see a loud, blaring warning sound, too.
