Just yesterday we were in a situation in office where a projector would have added so much value to whatever we were doing. But despite the giant leaps this particular technology has made, there is still a lot amiss when it comes to convenience and practicality. This is why over the past many years a new segment of Pico projectors has been making big strides. Pico projectors are really handy and portable enough to come inside any backpack. We just tested the Portronics Progenie.
Portronics Progenie review
The Portronics Progenie is a 100 Lumens, 854x480p resolution projector about the size of a small watch box. It can throw images up to 80 inches in size, but is just 200 grams in weight. The Portronics Progenie comes with a remote, a small tripod to prop it up and the ability to play from HMDI, USB and a card reader. It has an inbuilt speaker as well as an auxiliary out option.
Portronics Progenie price in India: Rs 29,999
Portronics Progenie: What is good?
Well, we will have to start with the size for that is clearly what makes this a unique product. No, this is not the first projector that is this small, but this is certainly among the few pico projectors that can pack in so many features. Just the choice of sources was good enough for me to be interested the Progenie.
The image quality is good, though I would have liked it to be Full HD. There is a focus dial on the side to easily get the clarity you need. It worked well, though I did not have a screen to project on. The 100 Lumens is good enough to overpower an off-white wall and make content the king. Thankfully, you do not have to play around with keystone adjustments to get the image shape right and just keeping the projector in the right place helps.
Controlling the projector is easy and there is remote which can do most of the stuff. There are some controls on the side of the box too. But this is among the most uncomplicated projectors I have seen. It is as easy as select source, find file and start playing when it is from the USB or SD card and a simple plug-and-play from HDMI. There are easy settings for picture quality too, but don’t expect too much here. Also, this projector has a fan inside that keeps it relatively cool even after a longish movie screening.
Portronics Progenie: What is not that good?
The projector couldn’t recognise the media files I tried to play via a USB drive. So you will need to be a bit choosy about the kind of formats you save your files in.
I know it is a bit of wishful thinking and doesn’t really work with projectors, but some amount of battery backup for a device like this will come in really handy for those who will buy this device.
Portronics Progenie: Should you buy?
If you are someone who is always on the move and needs to keep presenting stuff to a larger audience, the Portronics Progenie might be a good device to have in your bag. While this is good for homes too, I am not sure people who want to watch movies on a larger canvas would like to invest is a Pico projector as a larger, more powerful device makes more sense for them. However, I feel the Progenie is a bit expensive at Rs 29,999 and you should have a really good reason to pay a premium for the portability.
Samsung Galaxy S10 5G Launched: What You Need to Know
Samsung Galaxy S10 series was unveiled at the Unpacked event in San Francisco, and alongside the Samsung Galaxy S10e, Samsung Galaxy S10, and the Samsung Galaxy S10+, the company also launched the Samsung Galaxy S10 5G variant. Apart from the upgraded 5G chip, the phone incorporates a larger display, is heavier than the other three variants, comes with a quad camera setup, and packs a big 4,500mAh battery. From price, availability, carrier partners, to its hardware differences – we’ve listed all the important things you need to know about the Samsung Galaxy S10 5G.
Samsung Galaxy S10 5G price, availability
Samsung Galaxy S10 5G’s price was not unveiled at the event, but Drew Blackard, Samsung senior director of product marketing, told CNET that the phone may be a $100 more than the most premium Samsung Galaxy S10+, but didn’t go into more detail. For those unaware, the Samsung Galaxy S10+ price starts from $999.99 (roughly Rs. 71,000).
Mystery around the price is understandable given that the phone isn’t expected to launch until later this year with no specific timeline announced by Samsung. The company is reported to partner with Verizon first to launch the Samsung Galaxy S10 5G in Q2 2019. Later in the same quarter, Sprint, AT&T, and T-Mobile will also start selling it, the report stated.
Samsung Galaxy S10 5G processor, 5G modem
Samsung Galaxy S10 5G will improve upon network speeds thanks to the Qualcomm X50 5G modem integrated alongside the chipmaker’s Snapdragon 855 processor. At the event, the company said that the 5G variant is capable of downloading a full TV show season in minutes, play graphic-heavy cloud games with virtually no lag, and support real-time 4K video calls as well. It is coupled with 8GB of RAM and 256GB of inbuilt storage – which is not expandable via a microSD card.
Samsung Galaxy S10 5G sports a larger display
The Samsung Galaxy S10 5G comes with a large display than the other three, and it is seen sporting a 6.7-inchQuad-HD+ Curved Dynamic AMOLED display with a 505ppi pixel density and 19:9 aspect ratio. To, recall, the second closest premium variant, the Samsung Galaxy S10+, sports a 6.4-inch QHD+ Curved Dynamic AMOLED Infinity-O Display, retaining the same 19:9 aspect ratio but having a lower pixel density of 438ppi.
Samsung Galaxy S10 5G comes with a quad camera setup
The camera on the Samsung Galaxy S10 5G is also different, and it sports an additional 3D depth sensor with an hQVGA resolution. The other three sensors are identical to what’s integrated on the Samsung Galaxy S10+. The setup consists of a 12-megapixel 77-degree lens wide-angle camera coupled with 2PD autofocus, a variable aperture ranging from f/1.5 to f/2.4, and OIS; a 12-megapixel 45-degree lens telephoto (0.5x and 2x optical zoom) camera with autofocus, an f/2.4 aperture, and OIS; apart from a 16-megapixel 123-degree ultra-wide lens camera with fixed focus and an f/2.2 aperture. The setup also provides up to 10x digital zoom.
On the front, the Samsung Galaxy S10 5G bears a 10-megapixel Dual Pixel AF with an f/1.9 aperture and 80-degree lens. There is a second front camera, once again a 3D Depth Camera with an hQVGA resolution.
Samsung Galaxy S10 5G battery, other specifications
The Samsung Galaxy S10 packs a large 4,500mAh battery compared to the Samsung Galaxy S10+ which sports a 4,100mAh battery. This also makes the phone heavier and thicker than the rest, with dimensions measuring at 162.6×77.1×7.94mm and the smartphone weighing at 198 grams. The phone bears an ultrasonic fingerprint scanner, and comes with connectivity options like 5G (Sub-6GHz / mmWave 28GHz, 39GHz), Wi-Fi 802.11ax, Bluetooth v5.0, GPS/ A-GPS, a 3.5mm headphone jack, and a USB Type-C port.
Blockchain technology to help verify and trace natural diamonds
Scientists have developed a new method based on blockchain technology to help verify and trace natural diamonds, and fully guarantee their authenticity.
In a situation where natural, synthetic and fake stones exist in the diamond market, the system could protect the financial assets of market participants, said researchers from the National University of Science and Technology in Russia.
The modern diamond industry is undergoing a period of global restructuring, they said.
This expansion is explained by scientific achievements that are pushing for an increase in diamond volumes for potential applications, both for jewellery and industry.
Modern synthetic diamonds are almost as good as natural diamonds in terms of quality and chemical composition. With these trends, gemologists often cannot distinguish a good synthetic diamond from a natural one.
Taking into account the growth of the market and the multiple possible diamond origins, the guarantee of authenticity is becoming crucial.
A blockchain is a growing list of records, called blocks, which are linked using cryptography. Each block contains a cryptographic hash of the previous block, a time-stamp, and transaction data.
The solution proposed by Russian cryptographs and members of the Russian startup Bitcarat.com is a unique system of traceability of natural diamonds.
The system traces the entire history of the transfer of rights of individual stones, starting from the moment it is mined. Moreover, it is absolutely impossible to falsify this history.
“We offered a digital blockchain-based certificate for each natural stone,” said Alexey Dimitrienko, one of the startup founders, leading expert of the National University of Science and Technology.
“The technology will ensure the reliability of the history and authenticity of the stone through the use of the blockchain as a special mechanism for storing information.
According to the concept, while being mined, each natural diamond will be provided with a special digital code. This code will be entered into a distributed database, that is, a database that is stored by all market participants. Next, the entire history of the transfer of rights to the stone will be blockchain-recorded, becoming 100 per cent traceable.
This guarantee will be provided by the very principle of blockchain — it is impossible to falsify this code because of its full transparency. As a chain of information blocks, it records absolutely all transactions that occur within it.
Each attempt to edit the code — or to add an allegedly natural diamond into the blockchain — is permanent and changes the entire chain, which automatically shows any attempt to falsify.
The technology of the digital certificate alongside the idea of a digital diamond exchange and a diamond token has already raised interest among a number of the world’s largest diamond manufacturers.
The development team plans to launch a security token offering within one year.
This new wearable gives personalised information on environment
Researchers are developing a wearable device that aims to provide individualised information while gathering environmental data.
According to researchers, the device can measure the wearer’s physiological response to their immediate environment.
“We have added some sensors to the Fitbit watches that get information from air temperature and humidity, but also from the physiological response of the individual in that environment, such as your heart rate, your skin temperature, and your skin humidity,” said Negin Nazarian from UNSW.
“We have also developed some apps where you can interact with and tell us how you feel about the environment, so that way we can develop a methodology and a solution that is personalised and not one-size-fits-all,” Nazarian added.
The team says the aim of Project Coolbit is to create a personalised comfort model for each wearer, as well as crowdsourcing environmental data in the city in real-time.
“So your wearable already knows your personal comfort model, it knows your preference of the environment, the type of activities you like and some information about your physiological response,” the team said.
A Coolbit user could create a personalised heat safe route for a run, based on the previous information received by the wearable, according to the researcher.
“It also knows, based on the environmental information that other parties may give about the cities, the climate of the city,” the researchers said.
