Comments on the article

Below is a diagram of a simple PIC thermometer. The indicator (in my case BA56-12SRWA) is used with a common anode.

Temperature sensor DS18B20 (resolution 0.1'C) or DS1820 (resolution 0.5'C). The program itself will determine the type of sensor.

If there is no sensor on the line, "Err" flashes.

If the measured value is outside the measurement range, "---" flashes.

Measuring range from -55'C to 125'C.

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 ... >>

Computer speed - 100 km/h 04.01.2022

The Japanese company Sega (video game publisher) has created the fastest computer in the world. The Sega computer can not only handle any game, but it can also drive at high speed - in design it resembles a small remote-controlled racing kart. Sega tested its creation on the race track and it turned out that it accelerates to a speed of 100 km/h. After testing on the race track, the computer remained unscathed and continued to work.

Sega has joined forces with Intel and ASRock to create this computer. A truly powerful gaming PC is packed into a compact package, assembled from the following components: Intel Core i9-12900K processor (12th generation Alder Lake, 16 cores, frequency up to 5,2 GHz), ASRock Radeon RX 6900 XT OC Formula 16GB graphics card , 32 GB of RAM and a 2 TB SSD.

Sega timed this project to coincide with the New Year's sale of games on the Steam service, where games from this publisher are presented. Sega has launched a contest among subscribers on social networks and the lucky one will be able to win this unique PC, however, only in Japan.
