Chizhevsky's chandelier has been repeatedly described in various publications. Your attention is invited to an effective power supply circuit for the Chizhevsky chandelier, which is shown in fig. 4.62.
The T1 transformer is made from an old TVS-110 line transformer. The primary windings are removed and 70 turns of PEL, PEV wire with a diameter of 0,5 ... 0,8 mm are wound. Capacitors C1, C2 - MBM, K73-17 with an operating voltage of at least 250 V; C3 - POV (operating voltage 15 kV); Thyristors VS1 - KU221A, KU202K...KU202N. Resistors R1 and R4 are selected when setting up the ionizer for the type of emitter and room (you can use a construction one as R4). The main advantage of this power source of the ionizer is the use of the TV multiplier UN9/27. Looking at the UN9 / 27 circuit, you can see that in order to use it as a negative voltage multiplier, it must be turned on "vice versa". But for this it is necessary to "get" to point A. The experiment is best done on a faulty multiplier, dismantling (breaking) it, and finding the necessary connection point. After that, on the new multiplier, you should carefully scratch or drill the “fill” until it is in reliable contact with the necessary conductor, solder a piece of high-voltage wire to it and insulate the soldering point with epoxy glue.
Unused multiplier leads must also be insulated. Multiplier input - points "A" and "B", output - points "V" and "body". They are connected together and through a resistor MLT-2 with a resistance of 10 ... 20 MΩ are connected to the emitter.
The ionizer, assembled according to the proposed scheme, passed a year-long test and proved its high efficiency and beneficial effect on the human body. This ionizer is operated with a nichrome wire emitter with a diameter of 0,15 mm, stretched along the perimeter of the room at a distance of at least half a meter from the walls and ceiling.

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 system for simultaneous interpretation into the sign language of the deaf and dumb
27.05.2003
The Institute of Computer Technology of the Chinese Academy of Sciences, as a result of the development of intelligent command recognition technologies, created a computer system for simultaneous translation into sign language. It is intended for deaf children.
According to the project manager, Professor Gao Wen, this system has no analogues in the world and is capable of recognizing over 5 gestures. The words spoken by the operator are translated into sign language by the computer and displayed on the monitor. Now deaf and dumb TV viewers will be able to "listen" to the news.
The system can also be used for teaching sign language, as an electronic dictionary or as a tour guide.
