A new electronic gadget called the Loc8tor uses radio waves and multiple aerials, plus some fancy software, to locate postage stamp sized transmitters which can be attached to almost anything, within a range of up to 600 feet.
This thing sounds really useful. I know I put things down and then spend ages looking for them. It’d also come in handy when trying to find my glasses (if an incredibly small chip could be developed to attach to my glasses) as the loc8ter device is far easier to see when not wearing glasses than my glasses are.
This could especially be very useful for paticularly scatty people who have a heck of a lot of gadgets, keys and other small items.
