Light a burning candle with a powerful electric lamp. On the screen from a white sheet of paper, not only the shadow of a candle will appear, but also the shadow of its flame.

Flame shadow

At first glance, it seems strange that the light source itself can have its own shadow. This is explained by the fact that there are opaque hot particles in the candle flame and that there is a very large difference in the brightness of the candle flame and the powerful light source illuminating it. This experience is very good to observe when the candle is illuminated by the bright rays of the Sun.

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. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

TRACO TMPS ultra-compact power supplies 24.08.2021

TRACO has launched ultra-compact PCB-mounted power supplies to the market. The family includes three series with output power of 3, 5 and 10 W (series TMPS 03, TMPS 05, TMPS 10, respectively).

The main feature of these series is small size; 3 and 5 W series have a seat size of 1"x1" (25,4x25,4 mm), and 10 W models have a size of 1,5"x1" (38,5x25,4 mm). In addition, the power supplies have reinforced 4000 V input-output isolation and do not require grounding (II electrical safety class), are characterized by low power consumption without load (<150 mW) and can be permanently connected to the mains. The 10 W models have an overload capacity of up to 130% for up to 30 seconds, which makes it easier to start the main stages of the device. The TMPS family IPs comply with IEC/EN 60335-1 and UL 62368-1 safety standards (for consumer and information technology devices). The power supply has a built-in class B EMC filter.

Products are intended for wide use in various applications where a minimum size of IP and high security requirements are required: IoT applications, devices for security systems, industrial automation control and monitoring devices, sensors.

Features:

Ultra compact size
Safety Compliance IEC/EN 60335-1 and UL 62368-1
Reinforced insulation 4000 V
EMC class B
Overload capacity up to 130% (for TMPS 10)
3 year warranty

Application:

IoT applications
SENSORS
Industrial automation
Household appliances and devices.
