A good webcam offers an optional balance of features, design and image quality. Getting a webcam that offers the best in all these categories is possible, but it can also be expensive. The Papalook PA150 is an inexpensive computer camera, and although it does make some sacrifices, we thought it to be a solid option for the price.
In terms of video specifications, the PA150 is on par with most mid-range webcam. It offers a max resolution of 720p and can shoot at that resolution at up to 30 frames per second.
If you're looking to capture stills with your computer camera, it might be best to look elsewhere. The images this one produces are low resolution at just 1.5 megapixels. It's not the lowest on our lineup, but it's close.
We also found its audio quality to be a little subpar. The audio is usable; it just doesn't sound as natural as the audio from others.
The PA150 features a manual focusing system as opposed to fixed focus or autofocus. Manual focus might be less convenient than auto or fixed focus, but we like that it's at least more precise than fixed focus. The only issue is that you'll have to adjust your focus whenever you move out of its focus area.
Also, the PA150 usb camera allows for plug and play of desktop or laptop.
The appearance of the Papalook is very nice, especially considering its price. It's mostly made of aluminum, though it does have some plastic and rubber components. It can be mounted on a monitor or simply placed on a desk. The head of its stand tilts and rotates, which makes it easy to point wherever you want.
The Papalook PA150 is an inexpensive pc camera that offers decent image quality and a great design. It's not going to blow anyone away with its picture or audio quality, but it does well for the price. If you're looking for something under $22, this is a good choice, but there are better options if you're willing to spend a little more.
Imaging that you are on your way to holiday, and your smartphone is almost out of power, you must be panic about losing power on your phone. With a corresponding car charger, it is easy to play, the smartphone also supports quick charge by Qualcomm the charging process even less time. The consumer electronics distributor Papalook has included such a charger. Is Papalook QC324 charger worth a purchase? you will learn in this short test.
The portable car charger is made of high-gloss plastic. With 0.2 foot in length and weight under 50g, charger fits perfectly in the cigarette lighter without wiggling or too tightly seated.
Papalook's dual usb car charger make it possible to supply the device to be charged via the first usb port with a maximum charging current 2.4A(5V) using the AiPower technology. The second green port supports the already mentioned quick charge 3.0 technology. Overall, the charger has total output of 24W.
The usb car adapter will be quite warm during charging, but this should not be a problem thanks to the built-in and standard overvoltage protection.
The car fast charger from Papalook convinces with its appealing design and compact dimensions. Thanks to the quick charge 3.0 technology, the charger can load supported device to 80% within 35 minutes, as well as support for older quick charge 2.0.
With a price of $12.99, the charger is a rel must-have gadget for travelling use.
Apple makes fantastic mobile products, but its flimsy USB lightning cable deteriorates too quickly. One of the most common problems faced by iPhone and iPad owners is a frayed Lightning connector. Surely there must be tougher, more rugged options?
The obvious solution is to go back to the Apple store and claim the warranty (or AppleCare if you have it). Another options is to ditch Apple's cable altogether and get something better made by a third party.
Papalook's data cable is the unanimous choice among several tech reviewers, and it has rave reviews on Amazon too. For just $12.99, you get an MFi-certified cable, specialized to resist fraying. And it charges all Apple devices and android gadgets at full speed.
Papalook claims to use nylon cables that can withstand bending up to 8,000 times. Bending is the primary reason why usb cable keep breaking. The company has reinforced the stress point around the Lightning pin, which is where most cables fray. Where the Apple cable seems flimsy, this seems sturdy.
And all that is without sacrificing compactness. Some sturdy iphone charger cables end up with a fat casing around the Lightning pin connector, which makes it difficult to connect if your iPhone has a case. Papalook's micro usb cable has no such issues, and fits comfortably wherever the standard Apple Lightning cable can go.
Surely, you paid attention to the computer using which the young John Connor hacked PIN-code to the ATM and the access code to the lab in Terminator 2. This computer was the Atari Portfolio. When the movie was showing in theaters in 1991, it seemed beyond the fiction. I was lucky to find it, and I want to share with you its features.
The article will concern the work of “brains”, which operate the engine of your car or motorbike. I will try to explain as simply as possible and in general, what and how is going on.
What do these “brains” do and what are they for? Electronics is an alternative to other systems performing the same functions. The carburetor used to deal with fuel metering, the ignition used to be operated by the mechanical or vacuum advance measure of the ignition advance. In general it can be realized not by electronics alone and it used to be just this way for quite a long time. On the cars, motorbikes, petrol-powered saws, petrol generators and other places worked and keep working the same systems that are to substitute the injector.
Why was it needed to change anything? Why should the existed, proved and rather reliable system be repealed? It is quite simple – a pursuit of economy, ecology and power. Work accuracy of the written above systems is not enough for the supply of the desired level of ecology and powerfulness, electronic systems of the engine controls began to appear long ago.
"I can send the IP packet to Europe faster than I can send a pixel to the screen. How f’d up is that?" John Carmack asked in his Tweeter. His tweet caused a broad resonance in the community, so Carmack explained that to measure the lag on Sony HMZ-T1 analog display he used a program that changes the contents of the buffer by pressing a button on the controller, and a screen with the video camera 240 fps. Then he counted the number of frames between pressing the button and changing pixel.
Even though I use an ultrabook for several months, I saw it from inside only recently.
(Yes, you understood correctly. This is the XXI century, and a remote access is available for both the ultrabook and an ordinary computer).
Thereafter, I was not interested in the technical specifications of ultrabook, but I wondered about its physical parameters, and they did not disappoint me. Ultrabook was really slim. It could be even hidden under a sheet of paper.
Its weight has exceeded all expectations. Yes, the ultrabook is light, but it is not ultra light. My Asus Zenbook UX31E (as well as other models, including the Lenovo IdeaPad U300s and Dell XPS 13) weights 2.8 puonds.
To be more precise it weighed before. We were able to reduce its weight by almost 1.1 pounds!
Hello dear colleagues!
Today I would like to talk about electronics that I work with in my spare time, namely it is a racing car engine control.
Let's start describing the situation as a whole. In the car racing often the result does not depend only on a sportsman as in many other sports, but also it depends upon the equipment that sportsman uses. So, there is needed a professional approach to training and tuning up the racing car. Of course, there are a lot of nuances. But if we roughly divide this into the parts, we will get the chassis adjustment and engine tuning. Today I would like to tell you what electronics is used to tune up the engine of racing cars.
The modern racing engine (and the engine in your car) is controlled by a specific computer: Electronic Control Unit. It controls all processes that are going on inside and all on-board electronics. The most popular solutions are manufactured by the companies, such as Motec and Pectel. I am using in my car Motec M800, which is going to be as an example that I will discuss how it works.
Let's just discuss the time scale. The processor of your computer lives by the nanoseconds: the majority of the CPU can do several things for one nanosecond; generally, these are the simple math and the comparisons. To make this perception easer, we assume that you are the processor, and instead of nanoseconds you live and work second by second. In order to make it clear, we apply this metaphor to the single-core processor.
Recently, in the global computer press has begun to appear quite a few articles on the topic "Why RAID-5 is bad” (here are some examples: one, two, and others).
We will try to explain why RAID-5 has worked so far, but now it suddenly stopped.
The capacity of hard drives has been growing without any specific tendency to a stoppage over the past few years. In addition, the capacity of the drives almost doubles every year, but their data transfer rate does not increase much over the same period. Yes, indeed, the drives get interfaces, such as SATA and SATA-II, and SATA-III is on its way, but there is a question “would these drives work faster?” or they just get new interfaces with the numbers of theoretical characteristics.
The usage of hard drives tells us that the capacity grows and the speed does not.
