Screwdriver
All Xbox 360 controllers can be opened with a No. 1 Philips screwdriver. This is the most critical of the items you will need for any modification job; without the screwdriver, you will not be able to get to the device's critical components.
Soldering Gun
There are many kits that require soldering components to the circuit board. Having a variable temperature soldering gun or a soldering iron is critical when doing more intricate and complicated modifications.
Hot Glue Gun
To do jobs that require attaching components to the case, you will need a hot glue gun. Hot glue dries fast and is removable if items are improperly set. Glue guns are ideal for projects that call for placing LED lights in the controller.
Wire Stripper/Pliers
When moving components off and on a circuit board inside the controller, you might need needle-nose pliers to get into those tight places where your fingers cannot reach. Some pliers come equipped with wire strippers, which will be useful when connecting components with wire.
