Open Source Hardware List
SparkFun makes the list of OSH projects
Phillip Torrone has put together a fairly impressive list of projects that offer schematics, layouts, and firmware open to the world.
If you're looking to buy a kit or project for someone this winter, this is a great place to checkout. Open source hardware is also a good place to get a PCB layout to learn from and good tricks of the trade for your next design.
