The converter is designed to power electronic equipment with a nominal supply voltage of 5 ... 9 volts from a battery of 2 ... 4.5 volts, including emergency power supplies. The maximum power of the converter is up to 1.5 - 2 W, the no-load current at an output voltage of 9 volts and power supply from a 2.2 V source is about 30-35 mA. The efficiency of the converter at an output voltage of 9 V and power supply from a source of 2.2 V is about 75%. The output voltage of the converter is set by the applied zener diode. The inductor is wound on a ferrite ring with a diameter of 10 mm and has 40 turns of PEVTL wire - 0,35. Size printed circuit board 40x23 mm.

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 Autonomous car turns the driver into an instructor
09.06.2016
When autonomous driving is enabled, the driver takes their hands off the steering wheel and feet off the pedals. He should be in the car - just in case - but his function is the function of a driving instructor: in which case, apply the brakes.
This approach to the development of an autonomous car was demonstrated by Carnegie Mellon University professor Raj Rajkumar. The university has been developing autonomous driving technologies for almost three decades, and this process was intensified last February as a result of a partnership between a well-known ridesharing company and Carnegie Mellon University's National Center for Robotic Engineering.
A professor showed attendees at a conference in Pittsburgh, Pennsylvania, the University's latest 2011 self-driving car, the Cadillac SRX, on a windy road lined with parked school buses and other vehicles, and explained the principles of autonomous driving through a camera.
"When the autonomous driving function is enabled, the driver takes his hands off the wheel and takes his feet off the pedals. He should be in the car - just in case - but his function is the function of a driving instructor: in which case, apply the brakes."
The car uses a set of cameras, lasers and four computers to monitor and analyze everything that is happening around. It can follow a given route, obey speed limits and traffic lights, smoothly enter curves, and brake or accelerate when circumstances require.

Got this converter. What can I say. Throttle took ready. The turns are smaller, the dimensions are larger, the wire is thicker. Zener diode 15v. The output voltage matches. But the current consumed at idle is 70mA... With a load with a current of 45mA, the current consumed by the converter is 330mA . The throttle must be wound with a thinner wire. And more turns ... We will try ....
