Super-modder Ben Heck has used his powers for good. Again! This time, he's helping the wheelchair-bound enjoy Guitar Hero 4's drums by using a blow-tube to operate the kick pedal.
Heck took apart the kick pedal that came with GH4's drum set and used the piezoelectric switch in it, McGuyvered it into a little chamber with a diaphragm and added a tube that uses air to hit the switch. Voila, instant breath-controlled pedal!
