Submission + - SHA-1 cracking on a budget (hackaday.com)

cloude-pottier writes: One thing that is always amazing is what people manage to pull off on absolutely minimal resources. One enterprising individual went on eBay and found boards with more than half a dozen Virtex II Pro FPGAs, nurse 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 using JTAG as to make reverse engineering the organization of the FPGAs on the board more apparent. More details can be seen on the actual project page. If an individual is able to pull this off for under 500 dollars, it almost makes one wonder what resources the government has available to them to do the same thing...

Submission + - Continuous Rotation about a Magnetic Ring

Sterling D. Allan writes: "The Searl International Space Research Consortium has published two videos at YouTube demonstrating a key proof of concept of a technology John Searl produced in the 1960's, but for which he was jailed, and his devices and papers pilfered by the government. The completion of this mock-up marks the first time since 1968 that a roller has rotated about a ring continuously. According to Searl, the purpose of the mock-up was to find out why the rollers spin, why they stay on the plate, and to see what input power is necessary for operation — to see what kind of rare earth material will be able to provide the input power in the place of the small electrical excitation. The next task will be to build a full Searl Effect Generator (SEG) capable of cheaply and safely producing electricity (15 kW) without fuel, pollution, friction, or noise. Anti-gravity applications will be pursued after that."
