Instructables has just posted its latest installment in its collection of HOWTOs inspired by my new novel Little Brother, a young adult book about hacker kids who use technology to win back their civil liberties from the Department of Homeland Security.

This week, it's instructions for building a simple device that will let you spot hidden "pinhole" video cameras:



With one hand, hold up the toilet paper tube to your eye. With your other hand, hold up the flashlight at about eye level and point it away from you. With one eye, look through the tube and scan the room. If there are any small points of light bouncing back, inspect it further. It might be a camera.
