This would be a device designed to fit in the expansion slot of a PDA (e.g. a Visor). It would be powered by the PDA. Apart from that it would be very similar to a device that has existed for years.
When the user loses his/her PDA in the house/flat, they would walk around, whistling. The PDA's
screen would light up, and it would start making noise. The device itself could have a speaker, so that it could be set to reach a loud volume if desired. It could also have bright lights of it's own.
This idea could be expanded so that, instead of picking up a whistling signal, it could pick up the signal from the user's car key radio transmitter. Although maybe not if the person is liable to lose important items! [link]

I've never owned a PDA, but don't they already have speakers/microphones built in? |

And you need to find it before the batteries run out. |

They do, but I don't think it would be possible to write software that could listen for a certain sound when the device was switched off, so the manufactures would have to do it as part of the OS or something. |

That's true about the batteries running out, though. |

Get a PDA that you can phone. |
