Since SHA-256 is so easy, why was BFL's FPGA power&performance estimates off by a factor of 5?
I know I am nitpicking, but they were off by "only" a factor of 4... A single draws 66W(*) from the 12V input --ignoring inefficiencies of the power adapter-- and 62W without counting the 2 (or sometimes 3) fans.
(*) Average measured from my batch with a clamp meter.
