I assembled this strobe circuit, only the R5 resistor was set to 100 ohms. It works, but this resistor and the lamp are very hot. I managed to cool the lamp with a fan from a computer power supply.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. 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, ... >>

Microsoft Surface Duo 2 foldable smartphone 24.09.2021

Microsoft has officially announced its second-generation foldable Android smartphone, the Surface Duo 2. The novelty has retained the design of the first-generation device. At the same time, the engineers have improved those aspects that caused criticism.

The Microsoft Surface Duo 2 smartphone contains two 5,8-inch OLED displays with a resolution of 1344x1892 pixels and a refresh rate of 90 Hz. The hinge used allows the device to be opened like a book or set up like a tent. Together, the two Duo 2 displays measure 8,3 inches in diagonal. The slight curve of the display allows you to view a small image (time, notifications) when closed. The screens are covered with protective glass Corning. The Surface Pen series digital pen is supported, and the Surface Slim Pen 2 version can be attached to the side of your smartphone using a magnetic attachment.

The novelty carries a Qualcomm Snapdragon 888 processor and supports 5G communication. These features have been significantly improved over their predecessor. Another improvement was support for NFC Qi wireless charging. The battery capacity is not specified, but it should be enough "for the whole day"

In the first generation model, only one camera was available. The Microsoft Surface Duo 2 version has already received a triple camera unit. It includes a 16-megapixel standard wide-angle module with optical image stabilization, a 12-megapixel ultra-wide module and a 12-megapixel telephoto module with optical image stabilization.

The operating system uses Android 11. Microsoft says 150 games, including Asphalt Legends 9, Modern Combat 5, and Dungeon Hunter 5, are optimized for using one screen as a controller while viewing the game itself on another screen.

The novelty will go on sale from October 5 at a price of $1499,99. The choice of users will be available in white and black color options for the case.
