Take a cylindrical plug. Make a hole in the center of it. Insert a thin metal or glass tube into the hole, through which then pass the axle (metal). Fix the axis motionless in wooden racks. Insert six to eight thin wire rods or needles into the cork, on which attach (as shown in the figure) paper cones.

air wheel

Place a candle end on a stand or a piece of tin so that the flame does not touch the wheel. Warm air will cause one cone after another to rise up, and the wheel will rotate.

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. ... >>

TCL NXTWEAR S Augmented Reality Smart Glasses 11.06.2023

TCL has launched new smart glasses that use augmented and augmented reality to provide an additional portable display for PCs, game consoles and other devices.

The main advantage of TCL NXTWEAR S is their dual Micro-OLED display, which can project a virtual 130-inch 1080p screen in front of the user, which looks like it is four meters away from it with a 45-degree field of view. Using USB-C, the Virtual Display can stream video from a PlayStation, Xbox, Nintendo Switch, PC, tablet, or (most likely) an Android phone. It can also display 3D content upscaled to 3,840x1,080. The screen has a contrast ratio of over 100000:1 and supports 108 percent sRGB color gamut.

The goggles weigh 85g and the USB cable adds another 30g. They have interchangeable front lenses for different sunlight conditions, adjustable nose pads and magnetic lenses for myopic users.

Google famously tried to popularize smart glasses a decade ago with the $1500 Google Glass, but privacy concerns over the built-in camera kept them out of the market. The company tried again with a $1000 enterprise-focused version, but stopped selling them in March, promising to support current owners until September.

These issues haven't stopped other companies from entering the smartglass market with cheaper consumer-grade models. Over the past few years, Meta, Razer, Amazon, Xiaomi and others have released smart glasses ranging from $200 to $400, mainly to bring features from other devices into the user's field of vision.
