Where did you find $0.10 UHF passive tags available in quasi-reasonably small quantities?

At least the hardware part sounds a lot like a worthwhile kickstarter project.
But even if this would only result in a well documented diy project with an open source software solution, I would be very interested.

You might want to have a look at the Mele A2000 or the Mele A100 as a replacement for the raspberry pi or dreamplug. $70 resp. $65, wifi & case included, SATA adapter, 3x usb, vga, hdmi, spdif, wired ethernet.

“find”

That was an impressively creative spell-checker substitution…

Very cool idea.

Cory Doctorow describes a very similar RFID-based system in his novel Makers (full text here: http://craphound.com/makers/Cory_Doctorow_-_Makers.html; search for “monte cristo” to Findus the first reference).

That’s what I mean by tagging locations within them. It would be even more precise than just a particular room.

An interesting project. Their idea is to use fixed RFID readers, and thus passively monitor the progress of object throughout a building. This produces even less need for manual activity.

On the other hand, it drives up the cost significantly, to the point where it is not really worth doing for a residential setting.

Metal and liquid pose the most difficulty. This is indeed a risk, which I’m thinking of as part of the read range risk I discussed above. That said, I don’t think I really have any liquid items to tag, and perhaps can be creative enough with metal ones so that it’s not an issue.

Why not directly tag the rooms ? No more conjecture !

They have some bits implemented already.

I think a major problem could be what kind of things you want to find because depending on the material RFID technology could not work.
