Whenever I bring my TV-B-Gone out to restaurants, I look suspicious pointing it around. Mitch Altman, the device’s creator, concealed his by putting it inside a hat (see the TV-B-Gone Hat project), but I rarely wear hats and wanted a more subtle and dinner-appropriate solution.

So I bought a zippered hoodie sweatshirt from a thrift store and turned it into a wearable TV silencer. For the switch, I sewed paths of conductive thread to 2 little pads that are bridged by the metal zipper pull when it passes by, so all I have to do is zip the sweatshirt up or down to activate the TV turning-off action. It works great, and you can just unsnap the circuitry to convert it back into a normal sweatshirt for washing — or for avoiding trouble.
