Fix it with BEES.

My friend cameo is opening an urban beekeeping store, Her Majesty's Secret Beekeeper. She's got hives. Hives all over the place. And a blog, hmsbeekeeprfeed.

What's the cheapest you can get tiny RFID tags? I was trying to talk her into lowjacking a statistically significant percentage of her bugs so that her hives can twitter.

        Would you really want to be friends with a drone? I mean basically they are kept around until it's obvious that the queen is laying eggs, and then they toss them to the curb. They get a bit of excitement if the queen stops laying eggs, a new, virgin queen is created, then there's a mad rush to mate with her.

        They are useless male creatures who sit around and have women taking care of them by feeding and cleaning them, and have about a one in one hundred thousand chance of mating.

        So in other words, they are my D&D friends and me from high school.

        There's a Borg joke in this somewhere, isn't there.

    The only case I've heard of where insects were tracked via RF wasn't really RFID. It was harmonic radar, similar to that which is used in retail stores for anti-theft alarms. The tag was basically a small thing shaped like this:

    < --------[]---------
    wire diode wire

    Basically, the whole thing is an antenna, and exciting it at its resonant frequency causes a harmonic to be generated by the distortion from the diode. The scanning apparatus looked like a tennis racket, and researchers would follow it in the field.

    The diode was made by Hewlett-Packard, back before they spun off everything but computers and ink-suckers.

    I suppose you could identify individual insects by making the antennas different lengths, using a frequency sweep, and finding the point at which the harmonic peaks.

    If you really want lojacking, then you will need active RFID which needs a battery to work for a long period of time and distance.

    For "passive" the industry consider long range to be 1 m ot be read, while average range is about 4 inches.

    You might still need additional supporting discretes/electronics still for these (I didn't look closely):

    So it looks like readily available is about $.76 to $6 depending on part and volume.

    ..maybe one'd find oneself less disappointed if asking something like "what's the carrying capacity of..', just not the Swallows part.
