Flashlight Darkfad

07.08.2022

Engineer Jaco Di Muro presented an unusual Darkfade flashlight on the Kickstarter crowdfunding platform. It has a thoughtful shape, which, according to the author, unloads the wrist joint of the hand. Moreover, the brightness of the flashlight is adjusted by turning the brush.

Darkfade uses a convex lens that includes over 200 microlenses. They smooth and even out the light emitted by the powerful Samsung LH351D LED. The length of the light beam reaches 125 meters, and the peak brightness is 3800 cd. The flashlight is powered by a 18650 lithium-ion battery or directly from an external power supply via a USB Type-C cable.

The main feature of the accessory is the built-in gyroscopic brightness control, which reacts to the rotation of the wrist like a dimer. By the way, the flashlight has protection according to the IP68 standard, so it is not afraid of rain and even complete immersion in water.

The price of the flashlight for the first buyers of Kickstarter starts from 129 euros. The start of deliveries is scheduled for April 2023.

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 ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

The world's largest battery 05.01.2012

BYD, commissioned by the State Power Corporation of China (SGCC), has built what is arguably the largest battery in the world. The battery has a capacity of 36 MWh and is the size of a football field.

The giant storage facility was created to store energy from a complex of wind and solar power plants in northern China in Zhangbei County. The peak power of the complex is 140 MW, and the use of such a storage device, according to the creators, increases the efficiency of using renewable energy sources by 5-10%.

The battery is assembled from iron-phosphate cells, the choice of which is due to the long service life (20 years), relative cheapness and high peak energy efficiency. Iron phosphate batteries operate at temperatures up to 60°C and provide storage efficiency in the region of 95%.

The cost of the complex of wind (100 MW) and solar (40 MW) stations with a battery is $500 million. This is the first project of the Golden Sun national program for the use of environmentally friendly and renewable energy sources.
