Comments on the article
Fluorescent lamps (LDS) often become unusable due to burnt out filaments. In the literature, schemes for starting such lamps have been repeatedly described. I offer my scheme (Fig. 1), developed as a result of repeated experiments with dozens of lamps.

The table shows the values of part ratings for lamps of various wattages. The limiting resistor R1 must be wire-wound. If the lamp does not immediately light up when turned on, it makes sense (sometimes it helps) to swap its conclusions.

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 ... >>
Random news from the Archive Western Digital iNAND 7350 256GB Smartphone Drive
01.03.2017
Western Digital, under the brand name SanDisk, has introduced a new generation e.MMC 5.1 embedded flash module designed for use as a drive in smartphones, phablets and tablets.
The product received the designation iNAND 7350. 3D NAND technology is used in its manufacture. There are models with a capacity of 32, 64, 128 and 256 GB.
It is noted that the solutions of the iNAND 7350 series provide fairly high performance. So, the speed of writing information reaches 250 MB / s. The number of input / output operations per second (IOPS) is up to 22 thousand random reads.
Module dimensions are 11,5 x 13 mm with a thickness of 0,8 to 1,2 mm (depending on capacity).
Western Digital says the new products are suitable for ultra-high-definition video, professional-grade photography, augmented reality applications, and more.
It is expected that iNAND 7350 modules will be installed not only in cellular devices and tablets, but also in game consoles, Chromebooks and other gadgets.
