Backpack

http://www.instructables.com/id/How-to-make-a-backpack/

I've wanted to make my own backpack for years and as the contents of my backpack have settled, that is seaming more feasible.

The sewing is fairly complex, it may be worth finding a good starter project, like a tool bag.

Compartments

The bag will be composed of a few sections so that I can remove some easily.

Main

Internal compartments for notebook and laptop. Small pouch on top for power brick. The stuff I have in the container will go into a custom wrap that rolls up and attaches to the pack.

The main pack will also have a frame, probably from aluminum tubes.

Straps

I want small pockets on the straps. For pencils and my skeletool.

The straps will actually have paracord running inside them. I don't need paracord often, so I'm willing to make the trade off of losing the straps if I do need it.

Power

I'd like to build a LiIon supply into the pack. A usb port near my shoulder lets me charge right from the pack. I can also plug a flashlight in there. I'd like to put the batteries inside the main frame.

Padding

The back of the pack is padded with a thin layer that holds the towel. Like the straps, I don't use it often, so when I do, I'll just have to dry and replace it.

Water

I want a spot for my gopher water bottle. I'd like a second top with a plastic tube leading to the bottom so I can drink without taking the pack off. I'd like a bite valve (not sure what they're actually called). Not sure if I should buy or make this.
