German Super Pen Chides You When Making Grammatical Mistakes, As You Write


Before the art of putting pen to paper completely goes extinct, it is getting an opportunity for a few high tech improvements. The Lernstift pen pictured above is a German creation that is able to analyze your child’s writing in real time (or your own if you feel like you need it), and provide him with two types of corrections: orthographic and calligraphic. In calligraphy mode, the pen will vibrate when it sees that the letter doesn’t look right; maybe that ‘b’ is really supposed to be a ‘d’, for example. In orthography mode, the pen will vibrate for spelling and grammatical mistakes; once for the former and twice for the latter.

It comes decked out with a bunch of sensors and chips. Things like pressure sensors and WiFi, and even motion sensors are included to give you the ability to write in the air, should no paper be present. It’s all running off Linux, but of course we have no idea how well it performs. Given the wide range of writing styles, it would be surprising if it managed to achieve its task with an acceptable degree of accuracy.

It’s slated for release in August of this year, though there is no official price. A figure of €120-€150 (or roughly $160 to $200) is being floated, though isn’t concrete. And you can pre-order now, though it’s more of a statement of intent rather than a binding sales contract.

$17,000 Rifle Uses Linux Wizardry And Fancy Scopes To “Auto-Aim”

Let’s get the moral aspect out of the way first: we’re not big fans of killing for sport. We’re not going to turn this into a debate on the topic, but we’re only covering the TrackingPoint XS1 because, frankly, that’s some impressive tech. What is it? It’s a rifle that takes so much guesswork out of aiming, a child could do it. Not that a child should, but we’re just sayin’. The company calls it a PGF, a precision guided firearm. And this is how it works:

To shoot at something, you first “mark” it using a button near the trigger. Marking a target illuminates it with the tracking scope’s built-in laser, and the target gains a pip in the scope’s display. When a target is marked, the tracking scope takes into account the range of the target, the ambient temperature and humidity, the age of the barrel, and a whole boatload of other parameters. It quickly reorients the display so the crosshairs in the center accurately show where the round will go.

The shooting mechanism is also different than a regular gun. Once you’ve pulled the trigger, the shot won’t go off until you line up the reticle with the previously set pip; at the precise moment they’re lined up, the bullet leaves. This eliminates a lot of the shakes associated with pulling the trigger and dramatically increases accuracy. But you can also change your mind and take the finger off the trigger altogether, and cancel your shot.

DIY: Pi-to-Go Is A Portable Raspberry Pi Mini-Laptop

The beauty of the Raspberry Pi, in case you don’t know, is not only that it’s a full-featured PC not much larger than a credit card, but also that it’s so darn cheap: $25 for the base model, $35 for more RAM and a few extra features. It’s great, but it’s also barebones. Its potential is unleashed in projects like the above from one Nathan Morgan, called the “Pi-to-Go”, and which involves a custom-built, 3D printed case and extra parts to build a fully portable mini-laptop.

[The] 3D printed case is made up of 5 sections. The Portable Raspberry Pi-to-Go computer has a 64GB SATA II SSD, 4GB SD card and rechargeable battery with 10 hours of backup stuffed inside. The only put down about the awesome Pi-to-Go by Nathan is its very small screen and poor resolution – the 3D printed computer casing features a 3.5-inch 4:3 LCD display with 640 x 480 pixel resolution.

Nonetheless, Nathan has taken great care to make it an extraordinary device. He has the Pi-to-Go designed with a small USB keyboard with built-in touchpad mouse attached to the screen, much like a best college laptop. The device has built-in WiFi and Bluetooth and uses a 6 cell 48WH Dell Latitude D600 laptop battery with standard 9 pin connector.

The cost for the parts came up to $390, excluding the 3D print. This of course is starting to get more expensive than some of the larger laptops on the market currently, but that’s missing the point. If you want to learn how to make your own, hit the jump for links. Also, more pictures.
