Comments on the article

The design described below allows you to control the opening and closing of curtains from the remote control. For this, an electric motor is installed in the curtain rods.

(click to enlarge)

The design is made on the ATMEGA328 microcontroller using the Arduino BootLoader, the L293D drive driver (although I used the L293B plus external diodes, because I did not find the L293D), the TSOP1738 IR receiver, the DC motor. current from an old printer, etc. As a remote control, I used the remote control from the PixelView TV tuner. The program provides for the movement of curtains from left to right, back and step-by-step movement. As limit switches, a small magnet is used on the last hook and two reed switches located at the ends of the eaves. The last hook moves along the cornice string, on one side of which there is a motor, and on the other side there is a roller.

The source code of the program is written for Arduino. To decode the remote control signals, I used the NECIRRcv libraries.

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 ... >>

Danger of welding fumes 10.01.2019

An international team of scientists has found that no matter what type of electrode is used, welding will still produce harmful smoke.

This smoke will always contain solid nanoparticles of oxides of iron, manganese, silicone (about 41%, 18% and 6% respectively), as well as chromium. The average particle diameter is 5 nanometers, but there are also smaller ones among them. Metal oxidation products are generally toxic, but particles approaching 1 nanometer in size are of particular danger - it is known that they can even penetrate the human nervous system.

Particles in air suspension can move with air currents far beyond the area where the welder worked, and this must be taken into account in safety regulations.
