Comments on the article
A new version of the lighter for gas [1], as practice has shown, has the best characteristics. Its circuit is less critical to the selection of elements, in particular, the VD3 diode.
The generation frequency determined by the capacitor C2 is reduced. Excluded heating part - resistor R1.
Diode VD3 can be replaced with D220, D223. The T1 transformer has the same winding data as in the previous design, but there is a difference: 10-20 pieces must be inserted into the coil hole. permalloy or transformer steel plates 4-5 mm wide per coil length. You can also install a ferrite core from the DV, SV, IF circuits, or from the SB with a magnetic permeability of 400-2000. If the secondary winding T1 is wound with a PELSHO 0,09 wire, then the number of sections from three can be reduced to one or two.

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 Black hole for microwaves
27.04.2010
A black hole absorbs everything - both matter and radiation. Microwave black hole, created by Chinese scientists from the Southeastern University in Nanjing, led by Qiang Cheng, does not absorb matter, but does not allow microwave radiation to leave it. This hole is a metamaterial - a substance with a negative refractive index.
Recall that the most famous idea associated with the use of such materials is the invisibility cloak or the invisibility carpet, and the most useful is the lens with an infinite focal length. Scientists wound sixty layers of metamaterial on top of each other and got a cylinder, falling on which, the microwave seems to become entangled and cannot fly out. Instead, it is 99% converted into heat.
"We hope that this device can be used as a heat emitter or to collect energy. And in the future we want to create the same for visible light," the scientists say.
