The proposed development is addressed to cyclists - lovers of night riding with a brightly burning (from the generator) headlight.
The essence of the technical solution I propose is that a diode limiter is introduced into the electrical circuit of bicycle equipment with the simultaneous replacement of a standard incandescent lamp with another one designed for a lower operating voltage. As a result, the headlight will shine brighter and more evenly. And even with a sharp decrease in the speed of rotation of the armature of the bicycle generator (and such a situation is not uncommon, say, when driving on a bad road at night, when you involuntarily have to "slow down") the light does not disappear.
The overheating of the lamp is practically excluded. After all, the guarantors of durability here are semiconductor diodes, on each of which, when the current passes in the "forward" direction, the voltage drops by about 1 V. And since the current generated by the cycle generator is variable, two differently oriented garlands of diodes work in the limiter at once.
The six-month period of intensive use of a bicycle with modernized electrical equipment confirmed the high reliability and prospects of the considered technical solution. The headlight is bright enough during the day. Even when they are walking, and the bike (with the generator on) is being led nearby.

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 ... >>
| Random news from the Archive Xiaomi Mi PTZ Camera for hoverboard
20.11.2017
Xiaomi has released the Mi PTZ camera, which is designed specifically for use on the Mi Ninebot Plus electric scooter.
Xiaomi Mi PTZ camera is equipped with a three-axis optical stabilization system, a lens with a viewing angle of 104 degrees, it can record videos with a resolution of 1920 x 1080 pixels.
You can fix the camera on the scooter at different angles (0, 90, 180, 270 degrees), the camera allows you to record slow and fast video, and can also broadcast the video stream on the smartphone screen in real time and transfer the recorded materials using the appropriate application.
The novelty is offered at a price of $ 225.
