please, please, dont send new members to another site for information that is readily available at AM, the llamma tut is for a wired controller.
you will need a switched power supply (one that turns on and off with the controller) first determine what type of controller you have then use the proper schematic. these pics came from a king mike install, one of the six or so pined to the top of the rapid fire controller page. very easy to find, but here you go.
FTW the llamma link above is using a wired controller that turns off when the usb ports turn off. if you use thoase points for a wired controlled they stay hot.
use the red and black points cg is 3v and matrix is 2.5v
