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.

There's something magic about ancient cutting edge technology.

Not to mention ancient security exploits.

The family of a friend of mine had one of these ultrasonically remote-controlled TV sets, made somewhat later than my grandmother's TV which I've already mentioned.

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. :-)

Cheap thrills, I know. But thrills, nonetheless. :-)
