Suggest a cooking method painting paints.

The paint prepared according to this recipe is more durable than oil paint, odorless, dries quickly, and is not afraid of dampness and the action of cold water. These paints prevent wood from rotting and breaking, are less flammable and can be washed off with hot water and soap.

Prepare this paint as follows.

Zinc oxide (zinc white) is heated with a small amount of potato starch and any mineral or vegetable paint is added to this white powder. Separately, a solution of zinc chloride in water is prepared, a small amount of cream of tartar is added to this solution. This solution is added to the first mixture until the paint of the desired consistency is obtained: the paint made by this method is very cheap and gives good results.

The paint is applied with a brush.

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. ... >>

AVR-DВ microcontrollers with three operational amplifiers 18.10.2020

A new series of general purpose microcontrollers from Microchip. The family belongs to the line of high-performance devices and is built on the basis of the AVR core, which can now operate at a frequency of 24 MHz over the entire supply voltage range. The series consists of 11 devices with memory sizes from 32 to 128 kB, in packages from 28 to 64 pins.

The series is designed to bring analog signal processing, real-time control, and multi-voltage support on a single board to areas such as industrial devices, home appliances, automotive, and the Internet of things.

For the first time in the history of microcontrollers with the AVR architecture, devices have three operational amplifiers, thanks to which it is possible to form gain stages and filtering functions without the use of external components. The analog peripheral set also includes a 12-bit differential ADC, a 10-bit DAC, three comparators, and analog zero-crossing detectors.

The innovative Multi Voltage I / O (MVIO) technology has been implemented, allowing UART, SPI or I2C to communicate with external devices operating at voltages other than the microcontroller supply voltage. Other advanced Microchip technologies are also applied, increasing the flexibility and reliability of the system.

The AVR128DB48 Curiosity Nano Evaluation Kit has been released to evaluate the capabilities of the new series.

Characteristics of microcontrollers AVR-DB:

Clock frequency up to 24 MHz;
Up to 128 KB Flash, up to 16 KB SRAM, 512 Byte EEPROM;
Up to three operational amplifiers;
12-bit differential ADC;
10-bit DAC;
Three analog comparators;
Up to three analog voltage zero crossing detectors - Zero Cross Detectors (ZCD);
Automatic Flash Integrity Check - CRCSCAN;
Configurable Logic Module - Configurable Custom Logic (CCL);
Event system supporting up to 10 channels;
Reference voltage module - Voltage Reference;
Serial interfaces: up to 6 x USART, up to 2 x I2C, 2 x SPI;
Microcontrollers are available in packages:
8 pins (SSOP, SOIC and SPDIP);
32 pins (VQFN and TQFP);
48 pins (VQFN and TQFP);
64 pins (VQFN and TQFP).
Supply voltage range from 1,8 to 5,5 V;
Operating temperature range from -40 to 125°C.
