I've got a steering wheel and set of pedals for the computer (see link below). I'd like to modify the brake pedal because it doesn't work like a normal brake pedal, it works just like the clutch or accelerator going all the way to the floor. I presume the best option is a strain gauge. I've phone a couple of places and they can sell me something for over $200 but the set of scales I have in the bathroom has 4 of the things and it was something like $80. Where would I get something like that? How hard would it be to interface with the pedals that currently use a pot?
Thanks, Michael
