Just a couple of interesting gadgets.
The Sharkstopper is an accoustic shark repellent. It produces sound at a pitch sharks find uncomfortable, so they just swim away. That’s the idea, anyway.
If testing shows this is effective I can see the Sharkstopper being a big hit in Australia. There are about 12 shark attacks every year in Australia, and one fatal attack every five years, so it’s really not something to panic about. But that never stopped anyone.
Of course, even with one fatality every five years, Australians are still more likely to die from a shark attack than Swine Flu. But not if you are wearing the Sharkstopper. Presumably.
The Jupiter Jack is a little device you plug into your mobile (cell) phone. It produces a short range FM radio signal which plays your caller’s voice through your car stereo. It is easier and cheaper than a bluetooth connection or traditional hands free kit. Another one of those simple (and cheap) ideas you see and wonder why no one thought of before.
The Jupiter Jack claims to work with any phone in any car. Not yet available in Australia. Bother.
