Our electronic fishing rod provides for the placement of a power source and electrical wiring in the handle. This minimized the size of the rod and its weight. The use of a variable resistor makes it possible during fishing to give a "nod" of various oscillation frequencies - from 50 to 300 per minute.
The use of a relay of the RES-9 type (passport PC 4524202) allows you to reduce the current consumption to 12-14 mA, while the supply voltage can be from 2 to 4,5 V.
Rice. 1. Electrical diagram of the fishing rod
The electrical circuit (Fig. 1) is placed on a getinax board 55x18x1,5 mm in size and mounted in an duralumin tube with an internal diameter of 18 mm pasted over with a cork (Fig. 2). Power supplies are inside a special frame; contacts - one fixed, the other movable - on a spring.
The relay, circuit board with bosses, batteries, variable resistor, and back cover are one piece, with the relay, circuit board, and bosses glued together. The cone and body are also glued together.
This design will facilitate the repair of the fishing rod and the replacement or recharging of batteries.

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 A new type of nanotraps for studying the properties of proteins
06.09.2021
A new type of molecular trap that can hold a protein molecule for several hours has been developed by scientists at the Universities of Delft and Munich.
A technology called nanopore electroosmotic trap (NEOtrap) allows the study of individual protein molecules over a much longer period of time than was previously possible. This allows you to observe how individual proteins change their shape over time.
NEOtrap combines two nanotechnologies: solid state nanopores and DNA origami. Nanopores are small holes that scientists use as sensors for individual molecules such as proteins. Since proteins usually pass through a small opening in microseconds, they may only be available for study for a short time.
By sealing a nanohole with a nanosized bead made entirely of DNA, researchers can trap a protein in the nanopore for hours. The scientists created this nanobead using an approach called "DNA origami". This is a method that mimics origami folding, only on a micro scale, using nano-sized strands of DNA.
NEOtrap will allow scientists around the world to conduct completely new experiments, potentially revealing previously unexplored functional features of proteins.
