Samsung’s new app uses emojis to help people with language disorders communicate

 Once derided as a silly novelty, emojis are coming into their own as a communication tool. New app Wemogee uses the ideograms to help people with aphasia, a language-processing disorder that makes it difficult to read, write or talk. Read More

Reverse-Engineering the Peugeot 207’s CAN bus

Image
Here’s a classic “one thing led to another” car hack. [Alexandre Blin] wanted a reversing camera for his old Peugeot 207 and went down a rabbit hole which led him to do some extreme CAN bus reverse-engineering with Arduino and iOS . Buying an expensive bezel, a cheap HDMI display, an Arduino, a CAN bus shield, an iPod touch with a ghetto serial interface cable that didn’t work out, a HM-10 BLE module, an iPad 4S, the camera itself, and about a year and a half of working on it intermittently, he finally emerged poorer by about 275€, but victorious in a job well done. A company retrofit would not only have cost him a lot more, but would have deprived him of everything that he learned along the way. Adding the camera was the easiest part of the exercise when he found an after-market version specifically meant for his 207 model. The original non-graphical display had to make room for a new HDMI display and a fresh bezel, which cost him much more than the display. Besides displaying the cam...

The world’s new largest flash drive is the 2TB Kingston DataTraveler Ultimate GT

​So metimes, you need to be able to carry a preposterously large amount of storage in a more portable form factor. Enter Kingston’s DataTraveler Ultimate GT, the “world's highest capacity USB flash drive.” Available in either a relatively diminutive 1TB size, or a more staggering 2TB behemoth, there is a very good chance that the DataTraveler Ultimate GT offers more storage space in a gum stick-sized form than your laptop does in its entire hard drive. Obviously, the world’s high-capacity flash drive doesn’t come in a simple plastic shell, but rather a zinc-alloy casing for improved durability. Unfortunately (or fortunately, depending on your perspective), the DataTraveler Ultimate GT uses a USB 3.1 adapter, not USB-C, so you’ll need to break out a dongle to use it with some newer laptops. The USB 3.0 DataTraveler Ultimate GT will be out in February 2017. Pricing has not yet been announced, but it’s probably safe to assume that the world’s highest-capacity flash drives could also b...

World’s Fastest Camera Takes 5 Trillion Photos Per Second, Can Pause Moving Light

Image
High-speed cameras taking 100,000 pictures in one second are enough to fascinate us. But what about a camera that can film at a rate of 5 trillion images per second. It’s created by the researchers Elias Kristensson and Andreas Ehn at the Lund University in Sweden. The camera can make light slow enough that it could be analyzed by humans. In other words, it can be used to record events happening in the 0.2 trillionths of a second. In 2011, a similar camera device was created by the MIT Media Lab. But it was slower and capable of capturing 1 trillion images per second. The researchers demonstrated the camera by filming photons of light traveling a distance equivalent to the thickness of a paper. The trillion camera works in a different way in comparison to the normal high-speed cameras.
