Comments on the article
The long-standing debate about whether electronic means help from these vile creatures that can poison any summer vacation does not subside. We decided to contribute our two cents to this matter.
Diagram:
Everything is done on a single K561LN2 chip containing 6 inverters. On the elements DD1.1 and DD1.2, the generator is assembled directly, everything else is an amplifier. The generator frequency varies from 10 to 30 kilohertz. As a radiator, a piezoelectric radiator of the ZP-1 or ZP-3 type or any other that is at hand is used. The circuit is powered by a source with a voltage of 9 volts. For example, from the Krona battery.
The bourgeois analogue of the microcircuit is CD4049.
A big request to everyone who repeats the scheme to share their impressions - does it scare mosquitoes or not?

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 Dream Chaser spaceplane tested
15.11.2017
The American company Sierra Nevada tested its reusable Dream Chaser spacecraft for the first time in four years. In the future, it is expected to deliver cargo to the ISS.
The Dream Chaser spacecraft carried out a gliding test flight on November 11. It was launched from a helicopter and landed at Edwards Air Force Base. This is the first flight of the device in 4 years and the first demonstration of a successful landing (when the ship made its last flight in 2013, the landing gear failed during landing).
The Dream Chaser carried on board the same avionics that will be used for the ISS missions.
The test flight shows that the Dream Chaser can fulfill the role of a reusable cargo ship.
