I'm currently trying to learn how to understand technology by taking apart some old tech I have and trying to put together how they work. So far I've dissected an Xbox mic with a short in the wiring, and gotten some vague understanding of how it works, but for the most part I have no idea because I have no way to put it back together.

 

Basically what I'm asking is, do you guys have any tips on how to learn this stuff, and what to look for? My current list of stuff I can "dissect" consists of an old hardrive, an NES game that doesn't work, and a DVD player remote.

I would suggest looking into books and hobby electronics. Building little model kits of remotes and whatnot will help you get the hands on experience and books will teach you more in depth information.
