The WiFi Wart is a wall charger housing a 1.2Ghz quad core microprocessor and two WiFi radios. Security professionals and hobbyists can use it to conduct WiFi attacks, such as man in the middle, network deauthing and password sniffing. The design is completely open-source: electrical, mechanical and software. In addition, all the tools used in the design are also open source: KiCad, FreeCAD and Buildroot. There is a custom Linux distribution created from Buildroot that is used to boot the boards, I have successfully booted the boards and configured the wifi radios.
