Practical electronics 03/2018

The editor-in-chief recommends

Miniaturization. Trends prevailing in electronics perfectly fit into the theme of this EP edition - even more efficiently, even more sparingly, in even smaller space. You can read about this trend in our "Wehikule", an article on electronic components housings. In the same column, the second part of the article on operational amplifier circuits, which despite the universal digitalization of devices still play an important role, for example as a bridge between the analogue size and the microcontroller or A / C converter. Among the projects, it is worth paying particular attention to our "mini". In this column, we publish descriptions of useful modules and devices that can be assembled in several minutes. This time the Xbee module with ESP32, analogue-digital converter for Raspberry Pi Zero and motor controller (step or brush) with the DRV3906 system. Many of our readers build various CNC machines by themselves. That's why in the column "Automation and mechatronics" we decided to publish a description of the popular Mach3 program, with the help of which you can control the work of various machines. The article contains a complete instruction for installing, calibrating and using this very interesting program.
