How does an iPod work?

Black iPod 30GB 5G

Ever wondered how an iPod’s Click Wheel works? The answer is… *magic*. Ok, seriously. Actually the answer is something called capacitive sensing which works because of the conductive capacity of your skin.

No, I did not suddenly become an electronics whiz. I merely stumbled upon this Howstuffworks article on how iPods work. The article also answers a common question that pops up when playing with the iPod:

“If your finger controls the Click Wheel because your finger is a conductor, why can’t you control the Click Wheel with a paper clip?”

Find out how the iPod’s Click Wheel and other bits work in the article. Now you’ve got the perfect subject of conversation for your date this weekend.

  3. Hi everyone.
    What's a good alternative to the IPOD?
    I'm wondering if any of you can recommend a good MP3 player that is comparable to the IPod but WITHOUT they hype and price tabe to go with it.
    I was at the apple store a few days ago, and really liked the new 40GB or 80GB IPods that also show video, but was wondering if I could get the same kind of funcationality without that heftly price tag.
