Practical electronics 08/2017

Editor-in-chief recommends

We give readers the issue of Practical Electronics, where you can find 22 designs of useful devices that you can build in your free time. They will be useful in the workshop, home, hobby and other applications. In addition to the aforementioned projects, as last year we dealt with the subject of modeling. This time, we publish an article on multirotors popularly known as drones, a table with a list of model stores and ... a text about fishing boats for anglers. There is no laughing matter! These are also some kind of drones, but they fit into this definition. The unreal dream of many electronics is the construction of a tube amplifier, which is why I recommend paying special attention to the article on a perfectly made set for self-assembly of such an amplifier. Have you heard about the Amazon Alex project yet? I encourage you to read the article about the assistant, which maybe most of us will have at home. Will search the Internet for us, find information, give the time, timetable and weather forecast. Listed and other topics in the August EP. I encourage you to read and I wish you a great holiday!
