Here is my breadboard version of Andrew Holme's homemade GPS receiver.
I used a BeagleBone Black (USD$45) running the preloaded Angstrom Linux. A breadboard "cape" plugs into the BBB expansion connectors to which I attached a XuLA2 FPGA development board (USD$119) based on the Xilinx Spartan-6 LX25.
This quote is a gem:
You haven't really lived until you've dead-bugged a 4 x 4 mm QFN package with 0.5 mm pitch pads using 40 AWG wire.
Anyone working with software-defined radios? Or have steady enough hands to try this project? 
cheers,
drew
