The $299 Wristcam is a bulky-looking wristband that features an 8-megapixel, outward-facing camera and a 2-megapixel front-facing selfie camera. An earlier version of the camera was plagued by years of development delays and never made it to shipping. Now that a camera for your Watch is finally here, some observers are intrigued but underwhelmed. Mark Vena, a senior analyst at the tech advisory firm Moor Insights & Strategy, eagerly ordered a CMRA (the original name of the product, now called Wristcam) when it was first announced over three years ago, but never received one....

How to Get an Arduino Phone Interface The Arduino playground contains numerous tutorials and information about how to interface with hardware using Arduino. Two programs it recommends for developing mobile interfaces are pfodApp and Annikken Andee. The former is exclusively for Android, but the latter is compatible with iOS. Neither option requires any extensive mobile programming experience. Arduino and Android The relatively open platform of Android devices makes them great candidates for integration with Arduino....

Machine learning is a type of artificial intelligence, but it’s not the style and sort of A.I. we see on TV or in movies; instead, it’s the process used to create virtual intelligence. What Is Artificial Intelligence? Artificial intelligence is the measure of a computer’s intellectual ability. But there isn’t a scientific body that decides what is or is not, technically, artificial intelligence; the term is defined by whoever is using it....

What Is an ARW File? A file with the ARW file extension stands for Sony Alpha Raw, and is, therefore, a Sony raw image file. It’s based on the TIF file format and is similar to other raw files from Sony cameras, like SR2 and SRF files. A raw image format just means that the file hasn’t been compressed or manipulated in any way; it’s in the same raw form it was when the camera first captured it....

With all of these features, you might wonder what you’ll have to fork over to pay for it. Fortunately, it’s completely free! Avast Description: Important Features Avast’s no-cost AV program includes fully functional antivirus, antispyware, and heuristics engines. There’s also real-time protection of files, email, web surfing, and suspicious behavior. It scans browser plugins, too, to find installs that have a poor reputation and may be malicious.

This is not a minor refresh, as the Level.2 is filled with innovations, both big and small, to make your daily commute just a little bit easier. This electric bike includes a 48V/500W brushless hub motor that can be overclocked to 750W, allowing for speeds up to 28 miles per hour, though your speed may be hobbled to 20 mph according to local rules and regulations. This motor also includes a torque sensor, a first for the company, that promises a more nuanced and responsive pedal assist....

With Bose calling the SoundTouch 30 their “most powerful wireless speaker,” you’d be forgiven for thinking that this is a premium portable speaker. Although definitely premium in its build quality and features, this speaker is anything but portable, weighing in at a hefty 18.5 lbs, measuring a long 17.1 inches wide, and requiring AC power at all times to drive its prodigious sound output. The “wireless” part is merely a conflated reference to all the ways it can connect to other devices and services via Wi-Fi, Ethernet, and Bluetooth....

Can Two Routers Be Used on the Same Home Network? Yes, using two (or even more than two) routers on the same home network is possible. The benefits of a two-router network include: Support for more wired devices: If the first router is wired Ethernet, it supports a limited number of connected devices (typically only four or five). A second router provides more open Ethernet ports, allowing additional computers to join the network....

Every time a new technology floods the camera world, things get more expensive for a while. Autofocus, digital, and now mirrorless, direct-view cameras. And every time, Canon steps in after a few years with a surprisingly capable and affordable ($979 body-only) model that goes on to be a hit. The latest of these is the R10, a 24-megapixel mirrorless camera that does everything you want it to. “The Canon R10 is important to Canon’s future because, like the EOS Rebel series, it allows the company to offer a high-quality product at a less expensive, entry-level price,” indie filmmaker Braidon Thorn told Lifewire via email....

The desktop version of Google’s Chrome web browser will get a pair of new settings for you to adjust to improve performance. More precisely, these upcoming mode settings will let you better optimize how much (or how little) of your system memory and battery power that Chrome uses. Energy Saver mode, which Google says will make Chrome use 40 percent less energy, will automatically kick in (if it’s turned on) once your battery drops to 20 percent....

Your Camera Lens’ Enemy Camera lens fungus is one of those problems that you may not have heard about much, but depending on the climate in your location, it could be a problem with which you should familiarize yourself. Moisture trapped inside or on the camera’s surface causes lens fungus, where, when combined with warmth, the fungus can grow from the moisture. The fungus, as it grows, almost looks like a small spider web on the interior surface of the lens....

Depending on your recording needs and situations, one may be the better option over the other. The thing is, it’s difficult to tell the different types apart by looking at the microphone. Whether you plan to create a podcast or newscast, record music, or entertain an evening of karaoke at home, a dependable microphone plays a crucial role. Although most microphones stick to a familiar form, you can find ones exhibiting creativity with different shapes and sizes....

The mini3 by DDPai is unique among the dashboard cams we’ve tested because its primary function is as a social media and photography device, rather than as a basic security camera for your car. The picture quality was the best among the car cams we reviewed and is by far the most stylish and discreet. What really makes it stand out is the mobile app, which adds a social media element that makes owing this device a lot of fun....

Fortunately, turning off a vacation auto-reply and preventing new replies from being sent is even easier than setting it up was in iCloud Mail. (If you thought of a particularly clever and useful text for your auto-reply, you need not remember or save it elsewhere; iCloud Mail will keep it for the next time you want it to mail automatic replies.) Example Vacation Auto-Response For example, you may have a vacation auto-responder set up that sends reply emails stating “I will be out of the office until January 2....

Depending on the specific home theater receiver, video connection options may include HDMI, Component Video, S-Video, or Composite Video. However, does that mean that you are required to connect all your video source signals (such as VCR, DVD, Blu-ray Disc, and cable/satellite) to your home theater receiver? The answer depends on the capabilities of your home theater receiver and how you want your home theater system to be organized. If you prefer, you can bypass the home theater receiver for routing video signals and instead connect the video signal source device directly to your TV or video projector....

Multimeter A multimeter’s measurement flexibility combined with its precision and accuracy makes multimeters a useful tool in any electronics lab. Multimeters measure both AC and DC voltage and current as well as resistance. Multimeters are often used in troubleshooting designs and testing prototype circuits. Multimeter accessories include transistor testing modules, temperature sensor probes, high voltage probes, and probe kits. Multimeters are available for as little as $10 and can run several thousand for a high-accuracy, high-precision benchtop unit....
