AVerTV Mobile 510 - Android TV tuner that works without internet

28.11.2014

AVerMedia Technologies has announced the launch of a new generation TV tuner - AVerTV Mobile 510. It can be used to transform Android devices into personal portable TVs.

The AVerTV Mobile 510 will provide DVB-T/T2 signal reception without an Internet connection. To do this, you need to install the free AVerTV Mobile II application by downloading it from the GooglePlay online store. The application also supports channel scanning and scheduled recording.

The AVerTV Mobile 510 weighs only 7,5g. It comes with a highly sensitive telescopic antenna connected to the MCX connector. AVerTV Mobile 510 is connected to an Android device via a micro-USB 2.0 connector.
The TV tuner provides signal reception in the ranges 177,5 - 226,5 MHz (VHF) and 474 - 858 MHz (UHF), supports QPSK, 16 QAM, 64 QAM and 256 QAM modulation.

It should be noted that the AVerTV Mobile 510 is easy to use. To start watching TV, you need to download the AVerTV Mobile II app, connect your TV tuner to your Android device, and open the app.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Sun dimming to combat warming 01.12.2018

Cooling the Earth by injecting solar-blocking particles into the stratosphere can be very cheap. So, at least, says the most detailed engineering analysis of this project.

There is a project that can cool the Earth by launching millions of tons of sulfate particles into the atmosphere. This form of geoengineering is reminiscent of the effect of volcanic eruptions, which have significantly lowered global temperatures in the past.

Perhaps the most efficient and cheapest way to deliver particles would be to develop a new type of aircraft. If sulfates are released from ordinary jet aircraft, all particles will fall to the ground in a few days.

Currently, no aircraft can deliver many tons of particles to a height of 20 km. That is where they have to be in order to stay in the atmosphere for at least a year. And the use of rockets turns out to be too expensive. The new aircraft should have larger wings and four engines instead of two, as the air at that altitude is much less dense. The design of such a vessel will be unusual, but in general, no technological breakthroughs are needed to create it.

For a 15-year program, eight of these aircraft would need to be added each year, plus costs for crew, maintenance, fuel, insurance and training. The program is estimated to start with 4000 flights a year and end with 60 flights a year with nearly 000 aircraft. As the scientists comment, only the number of planes and flights will guarantee that such a plan cannot be carried out in secret.

What can be achieved with such a daring plan? Reducing warming by 0,1 degrees Celsius per year, which in general will give a decrease in temperature by 1,5 degrees, which in theory should be enough to prevent catastrophic climate warming.

How much does such a project cost? "We have shown that such a hypothetical program would be technically possible," says Harvard University's Gernot Wagner. By comparison, about $2 billion a year is now invested in green technologies every year.
