From master builder Ben Heck:
Ben builds his new game systems by taking apart old video game consoles such as the Atari 2600, or the NES and cutting up the internal printed circuit board (PCB) until it can fit in his hand. He then designs a custom case, which is cut on a CNC machine, to enclose the now-handheld device. His creations have been featured in such publications as Wired, Popular Science, and Maxim, and on G4tv shows such as The Screen Savers, Attack of the Show,and X-Play. They are also commonly presented on high popularity Blogs such as engadget.
