Unscrewing deep screws and screws. Encyclopedia of radio electronics and electrical engineering

Comments on the article
When repairing imported consumer electronic equipment (radio receivers, tape recorders, etc.), many people experience difficulties in unscrewing fixing screws or screws located at the bottom of very deep (up to 20 cm) "blind" holes. The length of the screwdrivers in such cases, as a rule, is not enough.
A set of homemade extension cords will help to cope with this problem. Each of them is a round rod, the working end of which is an ordinary screwdriver, flat or Phillips. At its technological end, the handle replaces the slot for a flat screwdriver.
An extension cord with a working end of the desired shape is lowered into the hole of the disassembled apparatus and a screw is unscrewed with a standard screwdriver. The extension cord is removed either with a magnet or by tilting the apparatus.

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 ... >>

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 mosquito prick
14.09.2002
A mosquito bite begins to be felt only after the bloodsucker injects poisonous saliva into the injection site, but the injection itself is painless. Taking the structure of a mosquito proboscis as a model, employees of Kansai University in Osaka (Japan) created a needle for a syringe, the injection of which is not felt.
The new needle is made of crystalline silicon oxide and is only one millimeter long and one-tenth of a millimeter in diameter.
