They managed to collect more than 100 thousand signatures under the relevant document and even get a vote in Brussels on the change of 3-3313. Legislation 3r3356. related to the repair of household appliances.
The main task of European activists now is to achieve such changes so that home appliances can be repaired on their own, using parts provided by manufacturers. The traditional practice of manufacturers not only household appliances...

Xiaomi wireless devices in the smart home ioBroker

Xiaomi wireless devices in the smart home ioBrokerGreetings to all home automation lovers. I decided to share the experience of using Xiaomi wireless devices with ZigBee interface. I, frankly, oppose the use of any wireless devices in any automation, from serious large-scale process control systems to small automation systems like fire alarm systems or smart homes, but Xiaomi solutions bribed with low cost, availability, excellent design and many positive reviews from users, I decided to try.
 3r33655. This post should be taken as step-by-step instructions for integrating ZigBee devices into the infrastructure of a smart home. Described ...

Development of buck-converter on STM32F334: principle of operation, calculations, prototyping

Development of buck-converter on STM32F334: principle of operation, calculations, prototypingIn my last two articles, I talked about the power module and the control board based on the STM32F334R8T6 microcontroller, which were created specifically for implementing control systems for power converters and electric drives. An example of a DC /AC converter was also considered, which was a demonstration, not a complete construction. Now it's time to do something simple, but useful, and most importantly complete. 3r31196.  
Most of the issues related to the project and power electronics are related to specific topologies: someone is interested in knowing the PFC control algorithm...
