Among the New Year's decorations, many people know the "Falling Snow" installation, which is a rotating ball with pieces of a broken mirror glued to it and illuminated by a lamp. But such an installation tires the eyes, and the effect of "falling snow" is not very diverse and quickly gets boring.
The improved installation is combined with a color-music device. Its design is clear from the figure.

The drum is easy to make from tin, it is covered with Moment glue and pasted over with pieces of a broken mirror. Changing melodies change the illumination, the effect of "falling snow" also changes.

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 Keys in the hole
13.04.2001
A strange-looking, but comfortable and effective keyboard for a computer began to be produced by a small American company, Kinesis.
The main keys are collected in two holes - for the left and right hand. Auxiliary are under the thumbs. When typing, the brushes comfortably rest on the inclined board of the keyboard; the way of moving the fingers is significantly reduced. The submerged layout of the keys has reduced the overall size of the keyboard, so that, according to the manufacturer, you can put the mouse with its mousepad closer to your hand, and in general there is more free space on the table.
Those who have tested the novelty say that it may take at least a month to relearn from a conventional keyboard.
