Often in amateur radio practice, a sufficiently powerful regulator is required to control various electrical appliances. For example, many people use a building hair dryer to mount / dismantle components and there is a danger of overheating the component. The scheme proposed below will reduce the power of the hair dryer. The circuit is quite simple and accessible even to a novice radio amateur.

Simple power regulator for electric heaters
Rice. 1 Schematic diagram of the power regulator

The printed circuit board was not developed, the device was assembled by surface mounting and was used to adjust the temperature of the hair dryer.

Attention! To control a more powerful load, thyristors must be placed on a radiator (150 sq. cm or more). To eliminate the interference created by the regulator, it is desirable to put a choke at the input.

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 ... >>

Nylon artificial muscles for future robots 27.11.2016

Creating an efficient muscular system for robots has always been one of the main problems of modern engineers. Artificial muscles turned out to be either not strong enough and flexible, or too expensive for mass production. However, scientists from the Massachusetts Institute of Technology managed to solve this problem, using the most common nylon.

People tend to create robots in their own image and likeness, because, as far as we can tell, a person is best suited to interact with the outside world. Thanks to MIT researchers who have found a way to use cheap synthetic nylon as artificial muscles for future androids, we are one step closer to our goal.

The idea of ​​an artificial muscle system is far from new. It has been developed for several decades, during which scientists using various materials try to imitate the properties of real muscle fibers, the main of which is the ability to contract and be quite flexible. However, researchers most often rested on the fact that complex synthetic polymaterials with the necessary qualities were very expensive and often were not at all as strong and elastic as real muscle tissue.

Trying to solve this problem, scientists at the Massachusetts Institute of Technology turned their attention to another material that would allow them to create simple and cheap artificial muscles. They found that when heated, the nylon fibers contracted while increasing in diameter, which caused them to bend. So, by controlling the exact amount of heat and the direction of heating the nylon, the researchers were able to repeatedly move the plastic fibers in specific patterns, which means they can be controlled using fairly simple systems.
