Oral B

[ptonsparky]

Took my wifes rechargeable Oral B toothbrush away from youngest GC who was quit contentedly chewing on it. After rinsing it off I noticed there are no direct electrical connections between it and the base. Someone know how they are doing this? It is not that old, so I better not take a hammer to it just yet.

There's a coil in the toothbrush and another coil in the base; the coils act as the windings of a transformer when you set the brush in the base.

Had a hunch that was it. I'll have to mark howstuffworks.com as a favorite.

Thanks

Why cant they apply that to other stuff like Ipods, cell phones, cameras etc so you dont have to have 200 differnt cords to deal with?

Because when they give you the phone for nothing they have to charge $47.00 for a 5 dollar charger.

If they wanted to they could make it like a 8x10 mat which would be the larger transformer and all you would have to do is set the item on top of it and it would start charging. Not a bad idea huh?

The system used in toothbrushes only works at extremely short range, but there is technology being developed that has a range of several feet.

Technology is amazing, except to me it is even more amazing that the answer to such an obscure question is printed in detail on a web page. :grin:

If you like that concept, do a search in "Induction cook tops". They are way cool and will be the next technology in my kitchen remodel next year.

Induction cooking has been around at least 15 years now. It can boil a pot of water in a third the time it takes conventionaly. If you cook a lot I would highly recomend it. But if your idea of a meal comes out of a box or can your wasting your money.

I thought about an induction cooktop, but then I'd have to replace all of my copper, aluminum and glass cookware. I don't own much iron/ferrous cookware, so consider the extra expense.

That's akin to why I switched from a Mac to a PC last time I needed a new computer.

I couldn't afford all the new OS-X-compatible software I would have needed to buy.
