Entering images into a computer using a hand-held scanner, I quickly learned that to achieve high quality scanning, the device must be moved, deviating no more than 5 degrees from the image axis, and done this very slowly and evenly. The first can be achieved using a guide ruler or frame, the second can be achieved by moving the scanner not manually, but by tying to it an ordinary thread wound on the shaft of a low-speed electric motor.
To move the scanner, I used a motor from a recording temperature meter DSOR32-162UHL. When powered from a 220 V AC network, its shaft rotates at a frequency of 3...5 min-1. Scan quality has improved significantly. Another suitable engine can be found in almost any apartment equipped with an electric kitchen stove. He turns a very rarely used cooking spit in her oven.

Artificial leather for touch emulation
15.04.2024
In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>
Petgugu Global cat litter
15.04.2024
Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>
The attractiveness of caring men
14.04.2024
The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
| Random news from the Archive New principle of X-ray generation
16.02.2021
X-rays, which are widely used in medicine, flaw detection and many other fields, are usually obtained using special vacuum devices called X-ray tubes. Inside these tubes, electrons are accelerated by a high electrical potential and collide with a metal anode. The energy of accelerated electrons is transferred to the metal atoms, which pass into an excited state, a complex oscillatory process occurs that generates a radiation flux in the X-ray range.
Unfortunately, the generated radiation flux spreads uniformly in all directions, and the properties of X-rays greatly complicate the task of focusing them and forming a narrow directional beam; moreover, the X-ray pulse front in most cases has an absolutely random shape.
However, physicists from the University of Göttingen have developed a new principle for generating X-rays, which allows you to get a beam directed in a strictly specified direction.
The new technology is based on a structure of three materials with completely different electronic characteristics. And the thickness of such a three-layer "sandwich" is only a few millionths of a millimeter.
An object made from such a thin layered material is placed in place of a metal anode in a conventional X-ray tube. X-ray parameters can be controlled at the stage of production of a multilayer anode by changing the order of alternation and thickness of layers of different materials.
