a clever workaround for wheelchair-bound gamers who possess a penchant for Rock Band drumming, but were unable to use the kit's kick pedal due to their disability. Ben Heck, modder extraordinaire, recently did the same for the Guitar Hero: World Tour set -- however, rather than attaching an extra button to drumsticks, Heck found an altogether brilliant method of using the set's foot-activated percussion: He made it breath-controlled.
It took a fair amount of fancy engineering, but Heck recently uploaded instructions to his blog that show how to remove the pedal's piezoelectric sensor, and make it respond to air pressure rather than, well, foot pressure. You can get further details on the modification, as well as a video of Heck giving it a test run, on his site. It's definitely an intriguing idea, though it more or less prohibits the drummer from simultaneously singing, making Phil Collins role-playing a near impossibility. Still, great work, Ben!
