I modded my tv-b-gone kit to embed it in a hoodie so I could wear it out to restaurants and turn off TVs all stealth-like. I used conductive thread to make a zipper-activated switch for such a purpose, and in true fffffat manner, published an instruction set for making your own. It’s great for a walk through the mall.

yo Becky, this is an elegant hack. I had a TV B Gone for a while but never used it cause it’s too big to really fit on a keychain. This way there is a much better chance you’ll have it on you… maybe attach one to a USB stick?
