Compared to the stark simplicity of a solid-state drive, the innards of a hard drive are a marvel of motion, sound and activity. Memsic uses a heated bubble of air doesn’t it? I love it. They’re great chips, and since they’re mass-produced you can add them to your projects for a song (if you can abide the tiny packaging). How do accelerometers work?

Traditional accelerometer may use a system with a mass suspended by a spring and a sensor to determine the deflection. Have you seen a hard drive as colorful as this one? Jon Kunkee liked Home environment monitoring system. Seagate Technology Paper. CNET. Jon Kunkee has added a new log for LED Light Clock. Another way to do it is by sensing changes in capacitance. March 13, 2008.

Memsic make true solid state accelerometers, in the sense that there are no moving solid parts. (Aug. 22, 2012), Goble, Gordon. Raphael Baron has updated the project titled deskmate. (Aug. 22, 2012), Samsung. But we have no idea of how they are made and only a inkling of how they work. Our base knowledge comes from the acronym: Micro Electro-Mechanical Systems. Crown Publishers. flokain has added a new project titled Smart cube. 2000. There are a number of approaches such as using a cutout cantilevered spring mechanism to determining deflection with capacitative sensors. Makes me wonder how difficult it would be to make an accelerometer with some aluminum foil (just as a demonstration). Jun. (Aug. 22, 2012), Farrance, Rex. Learn how your comment data is processed. An actuator arm, branching into multiple read-write heads, races … This changes the capacitive properties of the structure, which can be measured and reported to a microcontroller for further use. Looking for a project in which to use one of these devices? "Storage talk: Why you should get an SSD and keep your HDD, too." [Bill Hammack] has filled that knowledge gap with this explanation of how MEMS accelerometers are made and how they function. A computer compares the vehicle's actual movement to the driver's steering and throttle input. PCWorld. Hard to decide. [Bill] includes a diagram in his video after the break which shows the silicon-based system that moves as it is affected by gravity. Great presentation. 2011. Weird & Wacky, Copyright © 2020 HowStuffWorks, a division of InfoSpace Holdings, LLC, a System1 Company. (Aug. 22, 2012), Johnston, Casey.

Artwork: The broad concept of a capacitive accelerometer: as the gray accelerometer box moves to the right, the red mass is left behind and pushes the blue metal plates closer together, changing their capacitance in a measurable way.

Ask Hackaday: What Tools Do You Really Need For A Life On The Road? This 480-gigabyte solid-state drive made by SanDisk was retailing for $372.91 (on sale) when we last checked on Amazon. (Aug. 22, 2012), SanDisk. So yes, solid state, but the knock is current draw on this design vs. the analog part. (Aug. 22, 2012), Hutchinson, Lee. The Cost Of Moving Atoms In Space; Unpacking The Dubious Claims Of A $10 Quintillion Space Asteroid, The Shipping Industry’s Transition To Atomic Power And Faster Deliveries, “Enhance” Is Now A Thing, But Don’t Believe What You See. Only one way to settle this…. Now I’m so sad :) I never even handled a device to make the display follow the devices orientation, much less on a daily basis. >>>and it makes us wonder if these wear out, No, the moving parts are designed to stay below the fatigue limit. Dec. 8, 2009. "How It Works: The Sturdiest Solid-State Storage." Accelerometers are used in vehicle Electronic stability control systems to measure the vehicle's actual movement. This can help … (Aug. 22, 2012), Ngo, Dong. Jun. They look like regular accelerometers except they have a metal lid on the package. SearchStorage. List price was $699.99. Round platters, arranged on a spindle, can spin at 7,200 revolutions per minute.
