Manipulating Electricity

Well, without the advent of these devices, there could have been no radio, no tv, no computer, no cassette tapes, no electronic microphones, no speakers, no remote controls, no high tech toys, no CD players, no CD, no telephones, no LCD screens, no automation, no mainframes, no electonic sensors, no motion controlled alarms, no electronic fire alarms, no ATMs, no radar, no cruise missles, no lunar modules, no ECG, no optical fibers, no heart monitors, no digital watches, no mp3 players, no computers, no internet, no oscilloscopes, no electronic counter measures, no HUDs(heads up display), no DVD, no F-117, no smart bombs, no live television broadcast, no SMS messages, no GPRS, no frequency modulation, no amplitude modulation, no pulse width modulation, no short wave radio, no citizen bands radio, no phase locked loop circuits, no active filters, no bandpass filters, no html, no xhtml, no visual basic, no perl, no java, no c, no c++, no pascal, no basic, no css, no CALL CENTERS, no javascript, no USB, no mouse, no DSLR, no spectrum analyzers, no curve tracers, no cctv, no hdtv, no broadband... blah blah blah... did it get complicated??

If you can't understand, how about NO FLICKR? hahahaha.

This is a snapshot of an electronic circuit mounted on a PCB (printed circuit board). All electronic devices analog or digital has these kind of components, maybe smaller on some, and microscopic on some. Took this shot on one of my old remote controlled car controls. That small rounded brown thing in front is called a capacitor. The one with some stripes of different colors are called resistors. The black one on the center with multiple silver looking metals attached to it is called an IC (integrated circuit) -- it is usally composed of different transistors, capacitors, resistors and other electonic components. In the distance are groups of different capacitors too(the cylindrical looking components). A typical electronic circuit these days which are in your computers, cellphones and music players, contains millions of this components -- which are shrunk by recent technology to add more functionality and features to your device.
