After Spending Months Submerged, This Drone Can Launch From the Ocean

From remote villages to the tops of skyscrapers, there aren't many places a drone can't reach. Now, there's a chance you may even run into one while scuba diving in the ocean.

As reported by Popular Science, the CRACUN drone (pronounced Kraken) is a "Corrosion Resistant Aerial Covert Unmanned Nautical System” developed by researchers at the Johns Hopkins Applied Physics Laboratory. The 3D-printed, watertight craft is designed to stay submerged hundreds of feet beneath the sea for months at a time before eventually breaking through the surface and taking flight.

To keep it protected from the corrosive effects of salt water, parts of the body are coated with a commercial sealant that's commonly used in marine applications. The prototype was able to fly through the air successfully after spending two months underwater.

The research team has yet to reveal the intended applications for such a device, but they say the low production costs “makes it expendable, allowing for the use of large numbers of vehicles for high-risk scenarios.” According to Motherboard, the U.S. secretary of the Navy even went out of his way to praise the project. You can watch the CRACUN launch from the water in the video above.

The New MacBook Has a Crumb-Resistant Keyboard

Soon, you won’t have to worry about ruining your Macbook’s keyboard with muffin crumbs. The 2018 MacBook Pro will feature keys specifically designed to withstand the dust and debris that are bound to get underneath them, according to Digital Trends. The keyboard will also be quieter than previous versions, the company promises.

The latter feature is actually the reasoning Apple gives for the new design, which features a thin piece of silicon stretching across where the keycaps attach to the laptop, but internal documents initially obtained by MacRumors show that the membrane is designed to keep debris from getting into the butterfly switch design that secures the keycaps.

Introduced in 2015, Apple’s butterfly keys—a change from the traditional scissor-style mechanism that the company’s previous keyboards used—allow the MacBook keyboards to be much thinner, but are notoriously delicate. They can easily become inoperable if they’re exposed to dirt and debris, as any laptop is bound to be, and are known for becoming permanently jammed. In fact, the company has been hit with multiple lawsuits alleging that it has known about the persistent problem for years but continued using the design. As a result, Apple now offers free keyboard replacements and repairs for those laptop models.

This new keyboard design (you can see how it works in iFixit's very thorough teardown), however, doesn’t appear to be the liquid-proof keyboard Apple patented in early 2018. So while your new laptop might be safe to eat around, you still have to worry about the inevitable coffee spills.

A New App Interprets Sign Language for the Amazon Echo

The convenience of the Amazon Echo smart speaker only goes so far. Without any sort of visual interface, the voice-activated home assistant isn't very useful for deaf people—Alexa only understands three languages, none of which are American Sign Language. But Fast Company reports that one programmer has invented an ingenious system that allows the Echo to communicate visually.

Abhishek Singh's new artificial intelligence app acts as an interpreter between deaf people and Alexa. For it to work, users must sign at a web cam that's connected to a computer. The app translates the ASL signs from the webcam into text and reads it aloud for Alexa to hear. When Alexa talks back, the app generates a text version of the response for the user to read.

Singh had to teach his system ASL himself by signing various words at his web cam repeatedly. Working within the machine-learning platform Tensorflow, the AI program eventually collected enough data to recognize the meaning of certain gestures automatically.

While Amazon does have two smart home devices with screens—the Echo Show and Echo Spot—for now, Singh's app is one of the best options out there for signers using voice assistants that don't have visual components. He plans to make the code open-source and share his full methodology in order to make it accessible to as many people as possible.

Watch his demo in the video below.
