Capacitor handle. Tips for the home master

Builder, home master

From the used electrolytic capacitor K50-6, you can make a switch knob for radio equipment. In this case, it is necessary to free the glass of the capacitor from the electrolyte, and instead pour epoxy glue.

After the glue hardens slightly, the axis of the device handle lubricated with petroleum jelly is pressed into it - until it is completely cured.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Life is born at the same time as the planet 11.09.2012

Life is built from a set of complex organic molecules, including sugars. A team of astronomers led by researchers from the Niels Bohr Institute have discovered sugar molecules in the gas surrounding a young star. This amazing discovery may indicate that even during the formation of the planets, the elements of life already existed. The results of the observations were published in the Astrophysical Journal Letters.

A new star and a disk of dust and gas rotating around it - the future planets - were observed using the modern large international telescope ALMA, located in northern Chile. Among other things, astronomers also wanted to examine the gas for the presence of water vapor and understand the chemical composition of complex molecules. In a protoplanetary cloud of gas and dust, scientists have found glycolaldehyde, the simplest form of sugar. This is one of the building blocks of RNA.

Initially, the temperature of the gas and dust cloud is very cold - only ten degrees above absolute zero. Therefore, simple gases such as methane and carbon monoxide settle on dust particles and solidify like ice. Here they behave differently than in the free state - they can bind to each other and form more complex molecules. When a star forms in the center of a cloud of gas and dust, it radiates heat and heats the particles of the cloud rotating around it to about room temperature. Chemically complex molecules evaporate from solid particles like a gas. The radiation of this gas is observed by astronomers.

The observed star is located at a distance of only 400 light-years from us - is, on an astronomical scale, practically, our neighbor. The power of modern telescopes is already enough for scientists to study the gas in detail and see in it, in addition to sugar molecules, signs of other complex organic compounds, including ethylene glycol, methyl formate, and ethanol.

Astrophysicist Jes Jørgenson, associate professor at the Niels Bohr Institute and the Center for Star and Planet Formation at the University of Copenhagen, says the discovery has shed light on the origin of life on planets. Potentially new data, he says, means that the harbingers of life could have arisen in stars long before the formation of planets.
