Rationalization scheme power supply for heaters, to save electricity, reduce the load in the neutral conductor, remote control, extend the life of the timer and wooden lining (lining) of the sauna room.

The scheme was developed on the example of the Harvia electric heater, but can also be used for other types of electric heaters.

We remove from the control circuit of the electric heater timer. We exclude the neutral conductor from the power supply circuit of the electric heater.

We assemble the control circuit of the magnetic starter M1, using a timer. Via machine F2 and the closing contact of the timer, we supply power to the coil KM1 magnetic starter M1. Power contacts K1 when switching, they supply power to the heaters of the electric heater from the machine F1.

Advantages: increased the life of the timer; remote time control; reduced the load in the neutral conductor

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Upgradable rifle 20.02.2019

The leadership of the US Army said it was looking for a contractor to develop the latest type of rifle, which should come to replace the popular M4.

The new weapons will work with a special operating system reminiscent of IOS, which will be constantly updated. This statement was made by the leaders of the research center of the Picatinny arsenal in New Jersey.

According to the head of the research center, Colonel Elliott Caggins (Elliott Caggins), when creating a rifle, the military will be guided by the same principle as Apple when developing iOS. Instead of trying to implement many different technologies at once, the system will be gradually improved.

"Imagine Steve Jobs and his engineers were trying to turn the iPod Touch into the first iPhone with 3G. There were thousands of technologies they could put into the first iPhone, but they first grew the platform before it became a system," says Caggins.
