Way back in March, I gave you plans on how to build your own "BlueSniper" rifle in How To: Building a BlueSniper Rifle Part 1. With the BlueSniper rifle, you can discover Bluetooth devices and perhaps perform exploits such as copying an address book. But the physical construction of the rifle is only half of the battle.

In this installment, I'll cover the software side of construction by providing a step-by-step for building a custom Linux kernel for the rifle. I'll then guide you through transferring that kernel to the Gumstix computer that makes up the heart of the rifle and storing it in the Gumstix' flash memory. Finally, I'll show you how to use some of the basic Bluetooth tools that are built into the kernel.

You will need six things to get started:
