Video: How Accelerometers Know Up From Down

By David Ponce

The above video features Bill Hammack, The Engineer Guy, talking about one fascinating piece of circuitry that we’ve all pretty much started to take for granted: the accelerometer. It’s ubiquitous in our cellphones and mobile devices, and it’s what allows them to know up from down, and to detect even the most minute movement you make. But how do they work? How to they get the system to fit within a chip as big as a couple of grains of rice? Bill has the answer in the video, of course, and it makes for a fun viewing. At least for those geeks that are into understanding how everything around them works. Which we hope is most of you.
