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 ... >>

3D printer from a welding machine 03.12.2013

One of the limitations of 3D printing today is the materials used to create the model. Plastic, although the most affordable material, is cheap and rather high fragility. Therefore, students at Michigan Technological University decided to design a relatively affordable 3D metal printer and present their novelty to the public in the near future.

The estimated cost of creating such a printer should not exceed $1500. It will require a small truck welding machine and a microcontroller extracted from a "plastic" ReRap 3D printer and running on open source software to make it. The result of the work of such an unusual XNUMXD printer, which is based on a welding machine, can be jewelry-like parts with simple geometric shapes.

"Anyone who can get along with a welding machine can try to build their own version of our 3D printer and start a technology race," University of Michigan engineer Joshua Pearce said in a telephone interview.

The new 3D printer should be cheaper than the well-known MakerBot Replicator 2. However, the invention of university students is an order of magnitude more dangerous to use. Therefore, in addition to carefully studying the operating instructions, you should also enroll in locksmith, welder and mechanic courses. And that's not counting getting the basic skills of an amateur 3D printer.

So far, the plans of the team of enthusiastic developers are at an early stage of their development, but they are hoping for help in creating the project from outside. At least, even such an undertaking can already be called a serious step. To facilitate the processing of various metals, and not only them, but also polymers, fibers and much more is a really worthwhile idea.
