Read for a while and don't post, they get real cranky when someone posts "I don't know anything about pickups but want to build my own" do your research, google up "pickup building" there's a few site online showing how to do it. There's also my own site in my signature. Thats how I build my first pickup 3-4 years ago. It's not that great now(for me) but it's a good start to learn. (click on the sunburst bass, it's the third or fourth page)
The bible of the craft is Jason' Lollar's "Basic pickup theory and complete guide to making your own pickup winder" It used to sell for $20 but is now out of print and fetches about $150 everytime it pops up on ebay. I scanned my copy and made a nice profit when I sold it

If you really want to get into it, it's worth the investment (then resell it on the bay too once done) I've seen a copy once go for $300
