As an energy source, it is supposed to use Li-Ion batteries with a capacity of 6-12 ampere hours (4 pieces connected in series), Lead-Acid 12 Djkn or a car battery. It should be taken into account that when using the device, it is necessary to take care of the battery protection circuit from deep discharge and the battery status indication circuit. Coil inductance 100-160 mkGn (52 kHz 5A).
The output voltage is adjusted by potentiometer R3. A filter is assembled on coils L2-L3 to reduce the level of interference from the car's generator. If you do not need to limit the level of interference - you can not install the filter.
The microcircuit must be installed on the radiator.

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 ... >>
| Random news from the Archive Dense bulletproof tree
15.03.2018
Scientists from the University of Maryland have developed a technology for making heavy-duty wood, which can now be used in places where heavier metals and alloys have traditionally been used and are now being used. Moreover, the process of creating such heavy-duty wood is quite simple, it consists in pre-treatment of a wooden blank in a solution of sodium hydroxide and sodium sulfate at the boiling point of water. These chemicals remove lignin and hemicellulose from wood, substances that are the basis of its structure and give wood its strength. After such a chemical treatment, the wooden block is compressed between two plates heated to 100 degrees Celsius at a pressure of 5 megapascals, which is 50 times higher than normal atmospheric pressure.
As a result of the sequence of such processing, the volume of the tree is reduced by 20 percent relative to its original volume, and the density of the resulting material is three times higher than the original density. And, thanks to this, the processed dense wood acquires completely new physical properties. It withstands 11.5 times greater mechanical stress, which puts it on par with steel in terms of strength, but treated wood, at the same time, is significantly lighter than steel. As an example of the properties acquired by densified wood, the researchers fired steel balls at it with airguns. And if these balls passed through the untreated wood, then they either bounced off the board of the compacted wood or got stuck in this board.
The chemicals used to make compacted wood are not a significant environmental concern. At the same time, almost any type of wood is subjected to the compaction process, ranging from the most dense and heavy varieties to lightweight and less dense varieties.
Researchers believe that the new material can become an alternative to the use of steel where environmental cleanliness of buildings and structures being built is required, for example. In addition, certain vehicle components can be made from the new wood material, which will thereby become somewhat lighter and consume less fuel or energy.
