Just FYI, as I've seen a lot of confusion about humbuckers...
To get humbucking, you need the coils wired electrically out of phase. If you wind your coils in the same direction, this means you connect (e.g.) the start leads of the coils together and send the finish leads to the output jack. You also need the coils to be opposite magnetic polarity. These two kinds of out-of-phase add up to a signal that is in phase and hum that is out of phase.
Also, if your coils are not balanced (say one coil is 3k and the other 4k), you won't get as much hum cancelling. However, in my experience, unbalanced coils can make for an interesting sounding pickup, so it's not a bad thing if you don't mind a little hum.
At least, that's my understanding. It may be helpful to your project.
Good luck.
