Mini RC Helicopter Becomes Even Smaller Submarine

We often think of submarines as fairly complex pieces of machinery, and for good reason. Keeping the electronics watertight can naturally be quite difficult, and maintaining neutral buoyancy while traveling underwater is a considerable engineering challenge. But it turns out that if you’re willing to skip out on those fairly …read more

Lessons Learned Building a DIY Rebreather

While the homebrew rebreather the [AyLo] describes on his blog looks exceptionally well engineered and is documented to a level we don’t often see, he still makes it very clear that he’s not suggesting you actually build one yourself. He’s very upfront about the fact that he has no formal …read more

Undersea sensor is powered by sound waves from the surface

For continuously gathering information on ocean conditions, one thing that’s been proposed is a network of sensors that would transmit data from the sea floor. Changing their batteries, however, could be quite challenging. That’s where a new … Continue reading Undersea sensor is powered by sound waves from the surface

SubCruiser takes a unique approach to underwater jetpacking

Let’s face it: due to the amount of thrust required to lift a person off the ground, practical personal jetpacks may never exist – at least, not for use in the air. Underwater jetpacks, however, are another story. We’ve seen a few lately, wit… Continue reading SubCruiser takes a unique approach to underwater jetpacking

Underwater robot made to map and search abandoned mines

Fans of the movie Prometheus will recall the probes that were sent into the alien structure, autonomously flying through it to create a 3D map of its interior. Well, something kind of similar is now in development, in the form of an underwate… Continue reading Underwater robot made to map and search abandoned mines

Novel above/below Platypus watercraft navigates from dream to reality

Ten years ago, François-Alexandre Bertrand had an idea for a novel watercraft that cruised to a site and then lowered its passengers below the water to have a look around. We got to see the first renders in 2011, a working prototype followed … Continue reading Novel above/below Platypus watercraft navigates from dream to reality

GDome Mobile lets smartphones take "split shots"

You know those cool photos that are half-above the surface of the water, and half-below it? They’re called split shots, and a new underwater housing is designed to let you take them using a wide variety of smartphones…

Xpoovv underwater housing fits a variety of smartphones

More and more people are utilizing their smartphones for underwater photography, but there’s a problem with using a watertight housing made just for your device – it’s useless when you change phones. The Xpoovv, however, works with a wide ran… Continue reading Xpoovv underwater housing fits a variety of smartphones

Flipper-legged robot runs, swims, and is ready to hit the bigtime

Back in 2013, we heard about an all-terrain walking robot known as RHex. Designed in a collaboration between McGill University and the University of Pennsylvania, it used six flipper-like legs to scamper around. Now, its successor is taking t… Continue reading Flipper-legged robot runs, swims, and is ready to hit the bigtime

Breathing Underwater Using Wind Power

As hackers, our goal is to reuse something in a way in which it was not intended and [Rulof Maker] is a master at this. From his idyllic seaside location in Italy, he frequently comes up with brilliant underwater hacks made of, well, junk. This time he’s come up with a wind-powered pump to move air through a hose to a modified scuba mask.

The wind turbine’s blades look professional but you’ll be surprised to see that they’re simply cut from a PCB pipe. And they work great. The air compressor is taken from a car and the base of …read more
