A circuit of a 12 V DC to 220 V AC converter is proposed, which, when connected to a car battery with a capacity of 44 Ah, can power a 100-watt load for 2-3 hours. It consists of a master oscillator on a symmetrical multivibrator VT1, VT2, loaded on powerful double-phase switches VT3-VT8, switching the current in the primary winding of the step-up transformer TV, VD3 and VD4 protect powerful transistors VT7 and VT8 from overvoltages when operating without load.

The transformer is made on the Sh36x36 magnetic circuit, the windings W1' and W1 "have 28 turns of PEL 2,1 each, and W2 - 600 turns of PEL 0,59, and W2 is wound first, and on top of it with a double wire (in order to achieve symmetry of the half-windings) W1.

When adjusting the RP1 trimmer, minimal distortion of the output voltage waveform is achieved

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 ... >>

AMD FirePro S9300 x2 Dual Processor Accelerator 08.04.2016

AMD introduced the AMD FirePro S9300 x2 server accelerator, built on two Fiji GPUs. According to AMD, this is the world's fastest accelerator when compared to single precision. Members of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) are looking to use the AMD FirePro S9300 x2 to process massive amounts of data to create the largest XNUMXD map of the universe.

The CHIME project uses four 100-meter-long cylindrical reflectors instead of dish-shaped telescopes. The data collected with their help needs intensive computational analysis - at this stage, the capabilities of the AMD FirePro S9300 x2 cluster will be in demand.

As for the card, it is equipped with a PCIe Gen 3 x16 interface, occupies two slots and consumes no more than 300W. Cooling system AMD FirePro S9300 x2 - passive. In addition to two 28nm GPUs running at up to 850MHz, the configuration includes 8GB of HBM memory. The card supports OpenCL 1.2, HC (Heterogeneous Compute), C++ AMP and 64-bit Linux OS.

The price of the novelty is $6000.
