We have opened up a Playstation 2 controller for you people so that you people dont have to open
up your controller. The chip is very complicated for any ordinary man ( not a scientist or somethin’). There is a carbon sheet upon the controllers chip which connects the buttons and the analog to the chip which finally connect’s to the wire. And also there is a motor in the handle which goes round and hit’s the controller’s handle which make’s it vibrate. that’s all! Have a look at these pictures.
