Is there a device that that can be somehow activated by 'some' signal produces by today's cell phones (bluetooth, wifi, infra...) and then make a beep sound? Preferably it should be small, light, cheap, with low consumption of energy.
It should work as a beeper to find a thing that it is attached to more quickly. The thing is to activate it by a cell phone.
Any ideas?
