Interested in learning in hydro-any info/links?

Hey guys, I have been a soil grower for a few years now, and Im not ashamed to say...that I love it. That being said, I am very interested in looking into how hydro works. I am a complete noob when it comes to hydro. I'm hoping some of you experinced hydro growers have some good links to-

- DIY hydro builds.

-The basic principles of hydro.

-And just any helpful info on the general topic of hydroponic growing.

I'm not a information mooch and will definetely do the necessery reading, I just need you're help to find the material.
Thanks alot guys.
