Focus Description:

You have an ordinary balloon in your hands. Invite someone from the audience to inflate it and pierce it with a sharpened pencil so that it does not burst. Hardly anyone can do it.

Focus secret:

Meanwhile, everything is simple. Remove the case from the matchbox, insert the ball there. Puff it up and tie it up. Now pierce the balloon through the case with a pencil. The ball will not burst, since its middle part, the one in the box, is denser, and this gives the entire ball the necessary strength.

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.

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. ... >>

New low-level API will reduce the power consumption of ARM chips 13.04.2015

The market for wearable smart devices is growing, but its growth is constrained by the lack of any visible progress in the field of power supplies, and, as a result, a relatively short operating time. Developers understand this and are doing their best to reduce the power consumption of such devices.

ARM has taken a new step in this direction. ARM Cortex-M processors will receive a Silicon Labs EFM32 Gecko power management microcontroller and the corresponding low-level API.

Both companies, ARM and Silicon Labs, plan to use a bunch of these chips in a new generation of devices that form what is called the "Internet of Things" (Internet of Things, IOT). Unfortunately, Silicon Labs has not yet published details on exactly what level of savings it plans to achieve, but mentioned that the new API will allow for automatic smart sleep mechanism and power distribution depending on the level of activity of specific system components.

Preliminary tests of the "optimum sleep" system showed an impressive increase in efficiency: the LCD module consumed 1,03 milliamps before it was turned on, and after activation, the current it consumed in sleep mode dropped to 0,1 milliamps, that is, an order of magnitude. A very impressive achievement.

New software and hardware with such capabilities will be in high demand in the world of smartphones and tablets, however, for now, both companies will concentrate their efforts on its implementation in the world of the Internet of Things.
