Geek stuff, sci-fi... "Ever since the remote control's co-inventor Robert Adler passed away [in March], I've wanted to own one of the first remote controls. After trolling through eBay every now and then, I finally have in my hands a piece of the history of the button. But there's a mystery: which piece?" Entertainingly written piece on the world's first remote controls. I totally enjoy the simplicity of the ultrasonic remote: "All these early remotes are purely mechanical. No batteries at all. When you push the button, a small hammer strikes an aluminum rod, triggering a sound above our hearing range that's picked up by the TV. Each rod is a different length, thus a different frequency, thus distinguishable by the TV." Brilliant.

"We discovered that if we dropped our keyrings on the hardwood floor in just the right way, we could make it change channels without the hand-held remote."

That's not a security exploit, it's a useful feature ;) It could prove useful if, for example, someone else of your family is holding the remote controller and you don't like the channel and program he's watching...
