This is a question DIY Techno-hacks

Old hard drive platters make wonderfully good drinks coasters - they look dead smart and expensive and you've stopped people reading your old data into the bargain.

Have you taped all your remotes together, peep-show-style? Have you wired your doorbell to the toilet? What enterprising DIY have you done with technology?

Extra points for using sellotape rather than solder.

certainly be welcome to have the software and code.

You'd have to get the RFID kit (I've just looked and I can't bloody find the one I have on ebay any more - I was rather hoping to use the same readers and tags for the whole house).

Short of having 4 PCs in each room I am struggling to think of a way to narrow the search down - I'm sure I'll think of something though ;-)

Got it.
Arduino units with the parallax RFID reader sheild and the wireless network sheild (when it becomes available) telling a central TCPIP listener to update the database when any RFID tags get within range.

...or maybe some sort of pic.

Much cheaper than 4 PCs in every room, and much cheaper on electric too.

i'm by no means technologically minded
but would a portable reader work? [dunno if they can be portable...]
That way you could just wander through the rooms quickly and it'll scream at you when you're close.
Still WAY quicker than having to LOOK through every room.

[also, if you get this working, I fucking WANT one *clicks*]

You could have one in a laptop I suppose, but it's just not geeky enough ;-)

you attach two readers to one PC and triangulate the location of the tags based on the strength of the signal? That would give you a much better location for the keys. Bear in mind I have no idea how rfid readers work.
