and there is the development of various devices to order, help in creating interesting inventions, programming microcontrollers. Manufacturing of printed circuit boards, printing on a 3D printer, milling on a CNC machine and much more :)
Projects that are developing in parallel:

Data acquisition system.
Automatic data acquisition and transmission system via GSM. Many types of sensors allow you to use this system to monitor various processes. The compact size and the possibility of battery life will allow you to find a wide range of applications, such as:
- meteostation
- data counting system
- tracking of various technological processes

Signaling by radio
Compact module that helps protect property from theft. Can be used for the protection of premises, transport and hand luggage. Signaling to commit any actions or incidents.

Standalone event logger
Module embedded in other systems for recording various parameters:
- Device operation time
- Temperature or vibrations during transportation of certain goods
- Storage humidity, etc.

Metal detector with discrimination by type of metal.
Metal detector with discrimination by type of metal. The main focus of this metal detector is ease of use and low price. At the same time, the capabilities of the device are at the level of rather expensive models of famous brands..
