The accelerometers you can find inside cellphones clearly don't have gigantic masses bouncing up and down on springs—you'd never fit something so big and clumsy inside a phone! Instead, cellphone accelerometers are based on tiny microchips with all their components chemically etched onto the surf...
these team up to control the main vertical current through the whole transistor. Any electron which wanders across the very thin Emitter depletion zone can also wander across the thin Base segment and end up becoming part of the big flow of charge in the Collector Battery circuit. The Base Ba...
WhenPCswere first introduced, HDDs were relatively small in terms of data capacity, and they were quite expensive. IBM Personal Computer XT, released in 1983, was the first PC with a built-in hard drive as a standard feature. It originally came with a 10 megabytes (MB) or 20 MB hard d...
Each time a cell goes through an erase cycle, some charge is left in the floating-gate transistor, which changes its resistance. As the resistance builds, the amount of current required to change the gate increases. Eventually, the gate can't be flipped at all, rendering it useless. This ...
These big capacitors also function as current reservoirs that help feed the amp during high demand. The hydraulic equivalent of a filter capacitor is a hydraulic accumulator. The '16µF 475V' written on the cap is its rating of 16 micro Farads and 475 volts. The '10K 2W' written on ...

You can find capacitors as big as soda cans that hold enough charge to light a flashlight for a minute or more. Even nature shows the capacitor at work in the form of lightning. One plate is the cloud, the other plate is the ground and the lightning is the charge releasing between ...
Audiences first got a glimpse at 3-D technology way back in 1922 with the release of "The Power of Love." Whether they thought it was a curious thing or not is lost to history. But that began the somewhat cyclical fascination with three-dimensional film. The next big boom in 3-D happ...
A Phaser works in a very similar way to a flanger, but the first big difference is that it has only a few (usually, though not always, between two and six) notches rather than dozens of them, and the second is that these notches aren’t harmonically related to each other. The notches...
We still sat in the Activities Office, each of us on one side of the desk upon which sat the transistor radio, currently our portal to the outside world. We sat for a while staring at one another – my mind was racing. His mind ...? Well, I didn’t know what was going on in...
