I know you get 5 volts just from the initial power supply of the controler but i want to know is what is the voltage comming off off the rumble packs cause i want to run like 10 leds off of it and have them light up when when it vibrates?

Anyone tell me?

im no expert but im pretty sure this is how it is... no power essentially comes from the rumbles themselves... you would simply be using power flowing from them to power the LEDs... im pretty sure that is how it works.

just connect the led's to the motor them selfs

heres why when you start up the xbox there is no power going through the rumble motors but when the controller starts to rumble there is so just run a couple of little wires from the motor to the led's the when you art up your xbox the led's will be locked on but when they start to rumble they will flash because of the power flucuations created by the rumble motors
