Comments on the article
The electric fence is designed to protect pens and pastures of cattle and calves, to protect orchards, orchards, haystacks from damage caused by livestock and animals, as well as to prevent livestock from getting on highways and ravines.
The electric fence is powered by 220 V AC or by a battery of 6 A373 cells. Its scheme is shown in the figure. When powered from the mains, a voltage of 220 V is supplied through the capacitor C1 and the resistor R3 to the rectifier VD1, VD2 with voltage doubling. The rectified voltage charges the capacitors C2, C3 until the voltage on them exceeds the breakdown voltage of the dinistors VD3, VD4 (180-220 V).
When the dinistors break down, the storage capacitors are discharged to the primary winding of the high-voltage transformer T2. In this case, a high voltage pulse is induced on the secondary winding, which is fed to the wire of the electric fence.
When powered by a battery, the pulse generator on the transistor VT1 and transformer T1 is turned on. The pulse frequency is regulated by a variable resistor R2.
The electric fence was made at the "Contact" plant in Zenkov, Poltava region.

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 Electronic locks for Godson processors
05.01.2017
Designed on the basis of MIPS instructions, Godson's (or Loongson's) national microprocessor architecture is suitable for creating a whole range of computing solutions. Based on Godson, not only 8-core processors for servers were created, but also processors for PCs and laptops. Moreover, based on the Godson architecture, single-chip assemblies are being created that can be used in almost any electronics. But it will be a platform with impressive capabilities, which ordinary microcontrollers are unlikely to be capable of. For example, based on the Godson 1C300 assembly, a platform for creating robots has been prepared.
Developers consider the market of electronic locks with fingerprint scanners to be another promising direction for using Godson assemblies. At the end of December, an agreement was signed between the developers of solutions based on the Godson architecture and a number of Chinese electronics manufacturers to use the Godson 1C100 platform as the basis for electronic locks. At the moment, there are already prototypes of solutions that are ready to be delivered to the market, but the flowering of this direction is still expected in 2017.
The basic capabilities of Godson Fingerprint Identification electronic locks based on the Godson 1C100 platform include not only scanning and maintaining a fingerprint database, but also working with voice commands, responding to passwords, working with credit cards, and more with displaying information on the built-in OLED screen. Separately, it is possible to work with RFID keys, support for Bluetooth, laser keys, SIM cards (sending SMS), proximity sensors, video recording and other features, since the power of the computing cores is quite enough for all this.
According to analysts, over the next three years, the market will distribute over 500 million electronic locks. Oddly enough, the smartphone market will contribute to this, which makes fingerprint sensors a massive and fairly inexpensive solution.
