Topic tags/keywords: question cord space aliens cia mystery cord canister

I see these on cords of all sorts – USB wires, small low voltage chargers, etc, and I’m sure you’ve seen them too. Sometimes they slide freely up and down the cord, like a large bead on a string, and sometimes they are attached to the cord so they won’t slide. I started seeing these things about 10 years ago (right about the time I was abducted by aliens, but never mind that), and I see them more and more often.

The reason I’m asking here in the tools forum is because today I bought a Makita 3 1/8” planer and it’s got one of these weird doohicky thingies attached to the cord – the sliding type – and now my curiosity has got the best of me. What the heck are these things?

I’m guessing if I removed the thing my shiny new planer would work perfectly normal without it, and no secret agent men or space aliens would come after me, but I was wrong once and it could happen again.

Best I have been able to figure out is that it is a theft detction device. One blow with a hammer and it will pop right off.

Theft detection is probably right. Possible government GPS maybe. Long shot that it’s an alien spy device, but we never say never!

Something like that was attached to the leg of my last child. I too would be interested in what it is.

I’m guessing what you’re talking about are these:

In which case, they’re ferrite beads, which are designed to act sort of as a filter, primarily to prevent electrical/signal noise from interfering with other things near by

EDIT: looks like Karen beat me to it

Not real convenient to get a photo because I left the planer at work and taking my camera with me would be a hassle, as I’m not driving these days (don’t ask). I think it may be a locator, in case of theft. There was some writing stamped on it referring to security, but I was too busy to actually read it, so I’m guessing a tracking device. I wouldn’t really call it anti-theft device, since it does’t actually stop anybody from stealing it.

nomercadies, I think the one on your kid’s leg is probably from space aliens. You can remove it using a quarter and a goldfish, but it’s complicated. Anyway, the aliens will come after you, so I wouldn’t advise removing it. They have probes.

Loran, thanks for the tip about the ferrite beads. I looked it up – http://en.wikipedia.org/wiki/Ferrite_bead

Mosquito, nope. :) I’m pretty sure dbol and Monte nailed it… theft or tracking device.

I have one of those on my cordless cabinet saw. It is a receiver for wireless electricity.
