In the future, when ubiquitous little computing
devices broadcast their happy little bluetooth
clouds into the empty space around them, I think
there should be a protocol that lets people with
little money (or lots of time and a hunger for
electronic appreciation) do little helpful deeds
sums of money.
You know, like picking up litter, searching garbage
land fills for valuables, or turning in
aluminum cans for change.
A device that has gotten lost in the bushes
and needs to be found and returned to its owner,
say, could broadcast a low-range distress
signal saying, "find me, and I'll probably pay you
such-and-such an amount of money for taking me
to a drop-off point."
Things that are genuinely recycleable could work
Publicly installed devices that need batteries could
get them by offering money to anyone willing to
listen, on that protocol.
A car could want to be washed while its owner
||The dogs collar could ask for a ride home, the kids backpack could say,I've been forgoten, please leave me with the principal......etc etc
||Please DO keep thinking of ideas for bluetooth applications, meanwhile I'm working on an aerial, that uses all your useful RF energy to power my notebook, calculator, digital watch - Thanks for the free power!
||Ok, I've seen it several times here, and I give up.
What means 'bluetooth'?
||StarChaser, it's a little module for your computer, that transmitts data to anything else that is "Bluetoothed", using low power microwaves.
||This would be even better if it could be done passively (like an access card). That way disposable items (like aluminum cans) would only have to incorporate an antenna and diode (both of which could be built into the can) to provide resonance on a Bluetooth frequency - turning your Bluetooth device into a detector.
||I thought this would be the communication protocol used by the old 'two-cans-and-a-length-of-string' system.
