A new technology video has gone viral showing a backpack helicopter that is said to change the future of aviation. It is also mentioned that the technology will be produced in the next few years.
The futuristic invention, known as the CopterPack, recently completed its first flight over a beach in Australia, and it’s pretty impressive.
It looks like the helicopter is flying when used by someone strapped to his back. It seems that the user can walk on the ground and can also use it to fly at low altitudes.
The Backpack Helicopter consists of two giant turbines attached to the backpack, which allow the person wearing it to fly.
As per the CopterPack website, the device is described as an ‘electric backpack helicopter with self-leveling autopilot. The lightweight fuselage is made of a carbon fiber honeycomb. As seen from the video, there is no tail rotor, as the main rotor rotates in opposite directions.
The pilot controls yaw by fine adjustment of the differential gear on the rotor drive transmission. In other words, when one rotor is set to rotate slightly faster than the other, it induces a rotating motion. CopterPack videos have impressed many people.
Positive changes on the market. RAM is finally getting cheaper
RAM prices started to drop by 5-10 percent. both on the American and European markets.
Cowcotland reports that several Corsair and G.Skill module kits have already fallen by € 5-15 this month. In the US, prices for 16GB and 32GB RAM kits drop by an average of $ 10 to $ 30.
CowCotland reviewed price charts for several G.Skill and Corsair products, including the Trident Z and Vengeance lines. Some kits, such as the 2x8GB Trident Z and 2x4GB Aegis kits from G.Skill, were only cheaper by € 1-3. However, other kits, such as the G.Skill Trident Z 2x8GB 3000MHz, Corsair Vengeance LPX 2x8GB 3200MHz, or the G.Skill Trident Z 2x8GB 4000MHz show larger drops of 15-20 euros.
According to PCPartPicker, in the US, the same price cuts also apply to 32GB and 16GB kits. Especially the Corsair 2×8 GB LPX and RGB Pro 3200 MHz CL16 kits fell by almost $ 10-20 in August.
In general, more common memory kits suffer from greater price reductions, and rarer high-clocked kits with low latency have higher downgrade tolerance. The same applies to four-channel sets.
We recently wrote that contract prices in the RAM market should drop by a maximum of 5%. This is because manufacturers have to cut prices to get rid of excess inventory. The contract market situation translates into consumer prices with some delay.
Unfortunately, it is impossible to predict how long the price cuts will last. The last three quarters have seen steadily rising RAM prices, so reversing this trend is a major respite for consumers.
China Launches World’s First Glass Cable Car, Gives Passengers Beautiful Views
China has debuted its first glass-bottomed sky train, which will allow passengers to see 270-degree views of the country’s beautiful landscape.
According to a report on CNN, adapted on Wednesday (7/7/2021), the glass-bottomed sky train, which resembles the country’s most popular animal – Panda, was launched from the production line from Chengdu, Sichuan Province on June 26.
The train runs on renewable energy and can travel at a speed of 80 km/h. The train is part of the Dayi Air-rail project, which includes China’s first renewable energy suspension rail demonstration track.
According to Global News, reported on Wednesday (7/7/2021), the new energy aerial rail refers to a cable car driven by a lithium battery power pack.
Maximum 120 people can fit in each car. Given the fact that glass can reflect heat, the train is air-conditioned to balance it. It is made of lightweight carbon fiber material. Unlike the subway or light rail, the air-rail project combines tourist traffic and sightseeing features.
The Dayi Railway, with a distance of about 11.5 kilometers, has four stations connecting several important tourist points. The project is being developed by Zhongtang Air Rail Technology. They are targeting construction to be completed by the end of this year.
“The new generation of vehicles weighs about 2.5 tons, is 0.5 tons lighter than traditional ones, and has the lowest self-weight coefficient in the industry,” Zhong Min, deputy general director of Zhongtang Air Rail.
This YouTuber Builds a Mini PC That Can Run the macOS Big Sur Operating System
Running the macOS operating system on PC devices has become a common thing, but what happens if the operating system is run on a mini PC with not too high specifications? Of course, that’s a pretty interesting thing.
Recently a YouTuber named Ike T. Sanglay or Iketsj has uploaded a video where he tries to assemble a PC device that will later run Apple’s macOS.
Initially, Iketsj used the LattePanda Alpha SBC board which was then equipped with an Intel Core M3, 8GB RAM, 240GB SSD, and was also connected to an Arduio Leonardo.
The process of making the casing is also shown where Iketsj made it using a 3D printer. The results of the case can be said to be quite good where he can include all components such as the board, screen, and keyboard in a size that is not too large.
Although the process of installing macOS Big Sur (Hackintosh) on the device is not shown, at least Iketsj shows how the macOS can be used smoothly.
In the video, Iketsj says that it costs more to assemble the device than buying a Mac Mini from Apple. But Iketsj wants to do something challenging and doesn’t want to buy a ready-made device.
