Use your cell phone to detect mercury levels in water

It may not make your list of must-have camping gear, but a new sheet that detects mercury levels in water may prove useful to those who live or work downstream from industrial and mining sites (such as gold mines and coal-fired powered plants) and want to drink the local water.

When dipped in water for five minutes, the sheet, manufactured by chemists at the University of Burgos in Spain, signals the presence of mercury by turning red -- a process that can be seen with the naked eye.

Take a picture of that sheet with a digital camera, and you can learn the specific concentration of the mercury, a metal that is liquid at room temperature and has been found to cause long-term neurological issues after accumulating in the brain.… Read more

ReelSonar Bluetooth bobber finds fish, maybe sea monsters

It seems to me the point of going fishing is to get away from the hustle and bustle and have some quiet time with yourself, a fishing rod, and an implacable expanse of water. There's never a smartphone involved in my imaginary ideal fishing experience. I'm going to have to revise my idea of a good day fishing if ReelSonar reaches its Indiegogo goal.

ReelSonar is a combination of hardware and an Android and iOS app. A Bluetooth Low Energy-equipped bobber sends sonar signals down into the water. The information, including the depth of each fish, is relayed to your smartphone.

The app also lets you map the waterbed and share the location of your fishing hot spot with your buddies, if you're the type who doesn't hoard your secret fishing areas. There's even a bite alarm, which should wake you up if you snooze off with the bobber out on the water.… Read more

Computerized fishing rod won't put worms on hooks

If you like a little high-tech help when fishing for dinner, leave the fishfinder at home and try this electronic rod.

The SmartRod has an accelerometer that tells you when a fish bites your line. A sound or light alarm goes off so you can try reeling it in promptly.

Billed as the first of its kind in the world, the SmartRod is the subject of an Indiegogo campaign that's aiming to amass $50,000 for development with 20 days remaining. It's got a long way to go. … Read more

Disney Fish Hooks will appeal to parents and kids

Disney Fish Hooks takes after the popular Disney cartoon of the same name. The game follows Milo and his friends through different mazes. We found it surprisingly challenging and lots of fun.

Disney Fish Hooks opens with a simple menu. Through the Settings feature, you can turn the music and sounds off and on. The first step is to select a tank, but since we were new, we were only able to choose Freshwater High; the other tanks were locked until we scored enough points. The same went for the characters; we were only allowed to play with Milo since … Read more

Sustainable fishing 'SafetyNet' catches big prize

Imagine yourself as a little fish swimming far below the surface of the sea, just trying to make it in a big blue world. Suddenly, a horizon-encompassing net grabs you and takes you away from everything you once knew. Things go from bad to worse as the commercial fishing net rises and the pressure change kills you.

This fate, which often befalls millions of smaller non-target fish around the world every year, could change with the invention of the sustainable SafetyNet, which today was named winner of the prestigious 2012 James Dyson Award for design. … Read more

Raspberry Pi to cross Atlantic in solar-powered dinghy

What could make an awesome $35 bare-bones Linux system even more awesome? Sending it on an excellent, solar-powered trans-Atlantic journey, of course!

The FishPi project is one man's dream to use the Raspberry Pi microsystem to pilot a tiny craft across the ocean.

The idea is not just to redefine the term "budget cruise," but to prove that the inexpensive system can successfully guide and control a trans-oceanic vessel. The visionary behind the project, Greg Holloway, is currently working on a proof-of-concept vehicle for the project -- dubbed Fish Pi. Here's how he describes the plan on the project site: … Read more
