  • Arfids (RFIDs) -- Borrowing New Technologies To Find Our Lost Discs

    Hahah, damn, you're on a tear this morning, Bob. I know you're not a fan of aluminum, but I'm not sure if that stainless steel hat is quite doing the trick. I've always thought that RFID chips in discs would be pretty cool, great way to track down lost ones. Unfortunately, hand held RFID readers still cost several thousand bucks (yeah, I actually researched it one day).

    Cut here to new topic.

    A reader wouldn't be necessary. All one would need would be a detector. We could reuse the RFIDs off the products that we tear off and shitcan. I can't imagine a simple detector woud be terribly hard to design and build. Whudayathink?

    Just like a frikkin hippie, subverting a potential capital market.

    =================

    Just tested for any interference with a 2.4GHz phone. Nada. I imagine the RFIDs run higher up in the GHzs.

      Hmm...I don't know enough about the technology to know what would go into building one, but I like the idea. I know the Seattle library system uses RFID tags on all their materials, so the tag part of it's gotta be pretty cheap.

        Geeezo! Is that the same guy?

        Actually, all you need is a windowless van and a black helicopter or two. Remember when Gene Hackman swept Will Smith for chips in Enemy of the State? Maybe the NSA will help us find our lost discs.

          Borrowing New Technologies To Find Our Lost Discs (sorry to all you disc manufacturers and sellers).

          I'm inviting the topic cops to move the last few posts in And Now a Word From... to here, that we might sort out something many of us have been thinking about for a long time--having a portable detector for finding our discs.

              I continued clicking links until I found a reference to 2450 MHz. I immediately recognized this as the operating frequency of microwave oven magnetrons. We may be able to begin building an interrogator device using some microwave oven parts, though the power range of an oven's maggy would be quite dangerous, perhaps there are some tank circuits on which to base a less powerful oscillator.

              The range for reading completely passive RFID tags is said to be 20 feet. The coded pulsing necessary to send and read a bar code wouldn't be needed, just a 2450 MHz transmitter/receiver to pick up the reply. Our reader could be quite dumb, and therefore, relatively quite inexpensive.

                  Is this a BINGO!?!

                  http://www.hkc.co.th/Product42.asp

                  Reading this page would indicate the the 2450 MHz reader is for the more expensive battery assisted tags. It looks like is says the completely passive ones are in the UHF range.

                        Slightly related - my wife is convinced that I could get rich by developing a GPS based disc locating system.

                        Not sure that I would get rich, but the money I could save on my discs alone......

                            You've seen that hoax video where the people pop popcorn with cell phones? I read that it's done by placing a magnetron below the table. The people in the video survived!

                              Was the table approved for use in a microwave?
