Ben Heck's at it again, and this time, he's cobbled together a breath-controlled kick pedal for use with Guitar Hero (or Rock Band, if that's your flavor) meant for people in wheelchairs, or who don't have use of their legs, but still want to get in on the rocking action. After tearing apart the kick pedal to expose its piezoelectric sensor, he mods it so that, rather than reacting to physical pressure, it'll react to air pressure. To get the job done, you'll need some PVC piping, a hot glue gun, and a drill. Hit the read link for full instructions and video of Ben himself testing out the device!
