How to firmly and securely fix a wooden workpiece during its processing? There are such wedge vise applicable for both small parts and long boards.
The device can be made at home. A groove is hollowed out on the right side of the board. To its edges, flush with the upper edge, the guide strips are firmly screwed. Between them, two wedges are inserted into the groove. A metal visor with teeth is embedded in one, with which it must dig into the end face of the workpiece. Another wedge acts as a lock. It firmly holds the wedge with the visor in a fixed position, the wedges, as well as the guide bars, must be made of solid wood, namely beech, oak.
The part is fixed and released from the clamp with light blows of a hammer sliding along special cutouts made for this on the wedges.
The second stop for the workpiece is a pin with an iron comb. It is inserted into one of the nests hollowed out in the board.
In order to be able to fasten parts of different lengths, the distance between adjacent nests should not exceed the length of the groove.
When processing thin parts on a workbench, the protruding parts of the wedges and checks should not rise above the plane by more than 10 mm. Otherwise, it is difficult to rigidly fix the workpiece.

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 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.

The American company "Aprex" began to produce jars for medicines with built-in computer memory. Such a jar remembers the time and date when it was opened to take a pill.
From time to time, the jar can be connected to a computer and receive a printout of all the terms of taking the medicine. If the patient's condition has not improved, the doctor can determine whether the medication was taken regularly.
In the future, the company intends to provide this package with a sound signal that will remind you of the need to take the medicine.
