More than 20 years ago, I installed a table lamp switch and a simple mechanism in the bathroom (see picture). Its design is very simple and exactly performs the functions of the circuit breaker described in [1].

Simple bathroom light switch

The device worked for 10 years, after which the push-button switch had to be replaced. Only and everything!

This example is an excellent illustration of how an electrical circuit of a dozen and a half radio components can be replaced by a simple mechanism consisting of a lever, a spring and a pusher.

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 ... >>

Universal Driver GP-LC7028-Q5D 23.07.2014

GlacialPower, a division of Taiwanese technology corporation GlaicalTech, has released a new dual-mode LED driver for powering 7W to 20W LED lighting fixtures. The driver operation mode (constant current or constant voltage) and output power are set manually depending on the lamps or light boards used. Input and output wires are connected to strong convenient clips.

The GP-LC7028 driver is two LED drivers in one housing with a dip switch. It can be configured for use with various equipment, for this there are 8 modes of operation with a constant current from 250 to 700 mA and a constant voltage of 12V, 24V and 28V. as well as push dimming.

Safety is the number one priority for the GP-LC7028 LED driver. As a Class 2 power supply, it is fully isolated and complies with EN6134-1 and EN6134-2-13 safety standards, as well as EN55015, EN61000 and EN6154 internal structure standards. In addition, over current protection (OCP) and short circuit protection (SCP) ensure that this LED driver meets all safety standards for LED lamps and signage applications.

The driver is covered by a 3-year manufacturer's warranty.
