The OU has released some course materials under a Creative Commons license. They've included 24 technology units (units are sections of a course); including some I've taken as part of my ongoing quest to get letters after my name. You don't even have to register to get access to the materials. The courses range from technology, through science, health, maths, education to arts and history (which includes a creative writing course, handy for all those tech specs you want to write.)
