Evidently even Forrest Mimms isn't famous enough to fly without hassle when carrying a briefcase full of electronics; he writes at Make about his experiences, both before and after 2001. A relevant slice: After police were called when I was going through security at the San Antonio International Airport and after major problems going through security in Kona, Hawaii, I finally realized the obvious: Most people who don’t make things have no idea how to evaluate homemade equipment. Some are terrified by exposed wires and circuit boards, maybe because of bomb scenes in movies. So I gave up. Now my carryon bag is only half stuffed with electronics; the rest is shipped ahead via FedEx.
