cloude-pottier writes "An enterprising individual went on eBay and found boards with more than half a dozen Virtex II Pro FPGAs, nursed them back to life and build a SHA-1 cracker with two of the boards. This is an excellent example of recycling, as these were originally a part of a Thompson Grass Valley HDTV broadcast system. As a part of the project, the creator wrote tools designed to graph the relationships between components. He also used JTAG to make reverse engineering the organization of the FPGAs on the board more apparent. More details can be seen on the actual project page."
