The inventor of Brick'R'knowledge about this book: Brick'R'knowledge allows to pass electronic knowledge and conduct experiments in a simple way with small modular building blocks. In this book, which is further enhanced by their own blocks to be developed in order to implement certain functionalities. For this purpose, the term brickifizieren introduced. By adding less new members a variety of additional experiments may already be done. knowledge They wrap it in small-Contai ner. By designing new Bricks can be the correct handling electrostatic-African components implemented quickly and easily, without, as usual, the entire circuit must be soldered together consuming. How to reach from simple measuring instrument to applications with Prozesso-ren that control the developed system. The tube technology is not neglected in this book. Today it is used not only for nostalgic tube amplifiers, but also in industrial applications when it comes to performance. Tubes are very popular among radio amateurs in amplifiers. In this book, tubes are used, which are operated with hazardous battery voltage and therefore perfectly fit into the Brick System. Straight tube circuits are particularly easy with the Bricks reconstruct, understand and modify. All in all a successful work that offers a wide-SSE and interesting circuit collection for many electronics enthusiasts, but also many experiments that are suitable to a deeper understanding of the art.
