So break out your favorite microcontroller and let's get to work! Will the REAL Autonomous Lawnmower Please Stand Up Firstly, let's put one thing to bed. Those ridiculous robotic mowers that use a boundary wire and cut in random paths are not what we're talking about. Any hacker worth their weight in 0.1uf capacitors knows it needs positioning. How's that? , you ask? Well, just watch one of those things scurry about like some stupid bug running from the wind and you'll say to yourself You know, this thing would work a lot better if it knew where the heck it was. And that's what we're going to do. In order to make a real autonomous lawnmower, we need positioning. If we can locate our mower on an XY Cartesian plane, then the automation part is much easier to do. Yes, there are other ways to achieve autonomy for our lawnmower and I highly encourage you to discuss them in the comments.

Related pins are served up according to a similarity score that Pinterest's algorithms assign between images. Lens expands on that earlier search tool beyond images to include things in the real world. Image-detection programs identify an object and visual search digs up similar images, making it easier to buy a coveted item online. The potential for this kind of product-search innovation is interesting: You can search for things that won't fit in a standard search box, and more tightly connect things found offline with those found online. For shopping specifically, improvements to online discovery means new ways to find products youre interested in but may not have the words for, says Andrew Zhai, an engineer working on Pinterest's visual search. Visual discovery gives people a way to discover new brands and ways of styling that they never knew existed.

A deer that got itself stuck between two trees found a helping hand from a group of hunters. In November, a truckload of hunters were out driving on a hunting trip in Oregon when the car in front of them stopped suddenly. After spotting some commotion in the trees, the hunters discovered a doe, stuck between two trees. After multiple attempts, one of the men decided to grab a hatchet to make the job easier. The doe was less than pleased, but after several minutes the hunters managed to free the deer, and it ran off into the wilderness. Read more...

A documentary analyzed an interesting question about the Moon and NASA missions. Have you ever asked yourself why mankind has not returned to the moon in recent years? According to many researchers and Ufologists, the American space agency is hiding a sinister secret from society, and we are not familiar with everything that has occurred—and is still occurring—on the surface of the moon. Many people claim there is enough evidence to suggest there are Alien bases on the moon. Rumors, declassified documents, and whistleblowers have come forward saying that agencies around the globe simply cannot afford to let society know what’s really on the moon. The idea that there are alien bases on the moon would explain why we stopped so abruptly going to the moon. Also, with our current technology, why havent we created a permanent manned outpost on the lunar surface? Wouldnt it be easier to build a permanent structure on the surface of the moon, than to have a floating space station orbiting around Earth?

Nor were they filmed in the act. The military authorities admitted that the killing of the four was a mistake, but the military advocate general decided there would be no criminal investigation. The killers of the Abu Dahrouj family enjoy the anonymity that was denied Azaria and Dery, who killed Nadim Nawara , a teenager who posed no threat to him. Is being Moroccan a condition for the rare instance in which the authorities prosecute soldiers for killing Palestinians? Let me guess: It’s not a condition, but it helps. Among the ruling echelons, the non-Ashkenazi is still the “other” who it’s easier to present as the exception and to sacrifice on the altar of the false claim of purity of arms. Let me guess: In the state comptroller’s report on 2014’s Operation Protective Edge, which is due to be released this week, there will be no mention of the Abu Dahrouj family, nor of the other 141 families that lost three or more members who were killed by our military with the push of a button or two.

[Jeff Tranter] has done a number of retrocomputing projects. But he wanted to tackle something more substantial. So he set out to build a 68000-based single board computer called the TS2 that he found in a textbook. He's documented it in a series of blog posts (about 30 posts, by our count) and a video that you can see below. The 68000 had a very rational architecture for its day. A flat memory space was refreshing compared to other similar processors, and the asynchronous bus made hardware design easier, too. While most CPUs of the era assumed bus devices could perform their service in a fixed amount of time, the 68000 used a handshake with devices to allow them to take the time they needed. Most other CPUs had to provide a mechanism for a slow device to stall the bus which was complicated and, in many cases, less efficient. [Jeff] used KiCAD with an autorouter to lay out some PCBs and all his files are available on GitHub .

The keyboard accessory is sadly an add-on and not included in the box, but it's a better-than-passable attempt at being a good physical set of keys. It connects using magnets and Pogo pins in a rather satisfying manner, and while it's a little on the cramped side (which makes typing difficult) it's got more travel than the iPad Pro's smart keyboard, so we've no doubt you'd get used to it. The S Pen is in the box if you buy the Galaxy Tab S3 though, and it's chunkier than ever, making it easier to hold. Samsung is claiming the rubberised tip is more akin to sliding a pen across paper, and the resistance does help, but it's still not quite the same feeling. It's pleasant to hold, and the 0.7mm thin tip means you can work pretty accurately with the multitude of drawing apps available apparently PDF markup will be possible too, but we couldn't find that app on the demo unit we tried.

If only Marv and Harry were burglars today; they might have found it much easier to case houses and perhaps would know which houses were occupied by technically inclined kids by capitalizing on the potential vulnerability that [Luc Volders] has noticed on ThingSpeak. As an IoT service, ThingSpeak takes data from an ESP-8266, graphs it, and publicly displays the data. Some of you may already see where this is going. While [Volders] was using the service for testing, he realized anyone could check the temperature of his man-cave thereby inferring when the house was vacant since the location data also happened to be public. A little sleuthing uncovered several other channels with temperature data or otherwise tied to a location that those with nefarious intent could abuse. Not a vulnerability with the software per se, but [Volders] well observes that privacy settings must needs be altered whenever you're using an online IoT service.

But BMW is the most famous brand to use six inline cylinders and still makes iconic ones today. What are some of the pros to an I6 engine? Firstly, they're easier to build, work on and are more reliable. less moving parts, such as cam shafts, make the I6 the more reliable and the inherent balance of six cylinders in a straight line make it the far smoother engine than anything with a V configuration. There's also a great sound that comes from I6 engines that enthusiasts usually love. There are some cons, though. The length of an I6 engine makes it difficult to package, which is ultimately why automakers switched to V6 engines. Especially in today's world, which necessitates frontal crash zones and crumple zones. There is also quite a bit of torsional stress on certain parts, such as the crankshaft and camshafts. Because of the length of the engine, both kinds of shafts are quite long, which can cause serious stress in the middle while rotating at extreme speed.

That means you'll get a screen resolution of 1440 x 2880, and a pixel density of 564 pixels per inch. In comparison the 5.5-inch iPhone 7 Plus has a pixel density of 401ppi, while the Samsung Galaxy S7 Edge comes in at 534ppi. In short, the screen on the LG G6 should be eye-popping. The 18:9 aspect ratio also makes it longer than most smartphone screens, which means it's ideal for split-screen apps and movie playback. It's also apparently 30% less power hungry than the previous generation of LG QHD displays, as well as having smaller bezels, better touch performance, and being easier to view in direct sunlight. But it's also HDR-enabled, with both Dolby Vision and HDR10 supported - while there's a dearth of such content available at the moment, LG tells us that it's worked with both Netflix and Amazon to bring high-res HDR content to your phone, making use of the extra clarity and color reproduction to give high-quality images during your movie time.

One of the biggest challenges of traveling to Mars is that it's far away. That might seem obvious, but that comes with its own set of problems when compared to traveling to something relatively close like the Moon. The core issue is weight, and this becomes a big deal when you have to feed several astronauts for months or years. If food could be grown on Mars, however, this would make the trip easier to make. This is exactly the problem that [Clinton] is working on with his Martian terrarium, or marsarium . The first task was to obtain some soil that would be a good analog of Martian soil. Obtaining the real thing was out of the question, as was getting similar dirt from Hawaii. [Clinton] decided to make his own by mixing various compounds from the hardware store in the appropriate amounts. From there he turned to creating the enclosure and filling it with the appropriate atmosphere.

If a new startup has its way, highways might soon be filled self-driving semi trucks Embark , which emerged from stealth mode to launch publicly Friday , is the latest autonomous long haul solution to hit the road. The company claims its semi trucks will be able to self-navigate freeway routes from exit to exit without any driver interaction. The State of Nevada gave its blessing to Embark to test vehicles on public roads earlier this year, so the company has already begun to collect all-important on-road data to hone the system.

A lot of you have been asking me to draw a car and honestly I've been avoiding it! But for good reason… because it is hard. Drawing a car is a lot different from any other product conceptualization. I think this is because we have strong emotional associations with cars. So much so that our minds have built them up a system of symbols and it can be hard to get past those to draw what actually feels like an automobile. The most similarly difficult subject to draw is the human form and face. If you can master the human form and the car, then I think you can draw just about anything with ease. In this video, I set up a relatively simple perspective without a lot of forced vanishing points to make it a little easier on ourselves. The more you get comfortable with sketching a vehicle the more you can start to play with challenging perspectives. For this video, I chose a relatively simple front 3/4 view with more emphasis on the front.

The plastic frame tends to deform under this sort of load, just enough to stop the scanning bar moving across the platen. Instead, it's necessary to support oneself by placing the hands on the corners of the copier, hovering above the platen, ideally with an assistant to help you by pressing the start button. In all seriousness, though, short of reinforcing the copier bed with a steel frame to enable the easier imaging of the human anatomy, I was running short on ideas and paper was jamming repeatedly. This test run behind me, I had an agonizing troubleshooting session ahead. Luckily, there were still a few beers in the fridge. Amateur Copier Repair A jammed print. Notice the rippling from the paper bunching up in the various rollers. I had to figure out why the paper was getting jammed for your viewing enjoyment, I filmed the process and embedded it below.
