The Hacker Fab [1] project at Carnegie Mellon is creating and publishing guides to building simple fab equipment including photolithography and a sputtering system. For somewhat more complex equipment, I appreciate [2] from the founders of InchFab [3]. But maybe the easiest way to do (very low resolution) photolithography at home is to use dry film photoresist, which is like tape you can stick onto a copper PCB you then expose and etch; a cheap roll is ~$20 from eBay/Amazon.
