Make a Master Remote

So you’re ready to settle down on the couch in front of a good movie. Wait, there’s still work to be done: Turn off the lights, make popcorn, maybe even mix some drinks in the blender. No, don’t get up—just use a home-built receiver box that lets you turn any household appliance on and off with your TV remote. For example, plug a lamp into an outlet on the box (we’ve dubbed it the Zapper), program one of the remote’s little-used buttons to control it, and the next time you want to watch Halloween VI, you’ll barely have to lift a finger to set the mood.
