Basically the guy has a speaker on the back of the chair generating vibration one can feel when the rear tires slip or there is a gear change and another puck on the pedals doing the same when the front tires lock under braking or otherwise slip. Anyone know if the method he shows here would work with Beam?
I've done something similar, using two joystick rumble motors on the throttle and brake pedals connected to an Arduino. It works and this way it should also cost a lot less. ShakeIt doesn't exist anymore, it's been incorporated into SimHub.
