The off-the-shelf Bluetooth adapters didn't do what I wanted, so I built my own. This is the story of how someone with very little knowledge of electronics embarked on a project to build a 2.4 GHz wireless development platform and ultimately succeeded in creating a low cost device that can be used for Bluetooth sniffing and more. Find out how to build your own Ubertooth One, how to use it for Bluetooth experimentation and other things, and catch a glimpse of an exciting future of wireless security research enabled by open source hardware.
