Comments on the article
An increase in the output current can be achieved not only by introducing an external control transistor, but also by connecting microcircuits in parallel.
For example, by connecting two 142EN5A microcircuits, as shown in the diagram, you can obtain an output current of up to 6 A. Here op-amp DA1 compares the voltage drops across resistors R1 and R2. Its output voltage affects chip DA1 in such a way that the current flowing through it turns out to be exactly equal to the current through DA3. To prevent an unwanted increase in the output voltage when there is no load, the output of the device is loaded by resistor R6. It should be noted that at the maximum load current, the power dissipated on resistors R1 and R2 is no more than 2 W, so it is advisable to use such a voltage supply only in cases where the load cannot be divided into two parts (for example, into two groups of microcircuits) with a current consumption of up to 3 And feed from them from a separate CH.

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. ... >>
| Random news from the Archive Lenovo ThinkStation PX, P7 and P5 workstations
25.03.2023
Lenovo has announced the release of the ThinkStation PX, P7 and P5 workstations. When designing them, Lenovo collaborated with Aston Martin.
The collaboration focused on capturing Lenovo's signature red design, delivering the best possible performance, and expanding customization options. In particular, the 3D body grille is inspired by the iconic DBS Grand Tour.
All three new workstations feature a modular design with front drive access for ease of service and upgrade flexibility.
The devices feature the latest Intel processors with up to 120 cores and support for professional NVIDIA RTX GPUs. In particular, the 4th generation Intel Xeon Scalable and NVIDIA RTX 6000 Ada Generation can be installed in top models. Can be installed
The workstations feature a new chassis design, an improved cooling system, and a baseboard management controller (BMC) for remote system monitoring.
The new workstations will be available from May 2023.
