Reading time: 4 minute This volume includes practical electronic schemes that include, as much as possible, a wide range of fundamental electronic circuits in more complex schemes, in accordance with the desired application.
Reading time: <1 minut This collection is the first attempt to popularize the achievements of radio amateurs working for the introduction of radio electronics in the national economy.
Reading time: 2 minute This book has a practical character, the reduced models that are recommended for realization are given in the ascending order of the degree of difficulty, from all fields of application of electricity: from static electricity, to electromagnetism, to electric lighting, electrothermal, electric actuators, power supply, electric traction, electrocommunications, radio electronics, automation, etc.
Reading time: <1 minut In this paper, in addition to the basic notions on components used in construction, we propose a deeper knowledge of electronics through a series of assemblies with transistors easy to make, using radio parts produced by "IPRS" Baneasa and "Electro-Arges ". Before that, however, there will be a short journey into the micro-cosmos of electronics.
Reading time: <1 minut This bulletin presents a new chapter (for 1981) - "TVs with electronic games". It continues with "Troubleshooting Practice", a consistent chapter, with many more serious defects, most reported by amateur electronics.
Reading time: 2 minute This book is addressed to all young radio amateurs who love music and are interested in playing it in the most natural conditions. It is generally addressed to all young people concerned with the technique of sound recording, the problems of practical construction of audio frequency amplifiers, as well as their development and troubleshooting.
Reading time: 2 minute The book contains data on the following power sources: silver-zinc microaccumulator, gas accumulators, iron-coal elements, miniaturized alkaline accumulators, solar battery, atomic battery, thermionic converters and
Reading time: 2 minute This paper presents a series of examples of small automations easy to achieve, especially by young radio amateurs. Some assemblies are based on electrical applications. At each installation, however, there are several variants of use, especially electronic, which work with greater precision and safety in operation, presenting where appropriate both the variants with electronic tubes and semiconductors.
Reading time: 2 minute The presented book includes various DIY projects in the following fields: Electrical Engineering, Automation, Radio-electronics, Aeromodels, Navomodels, Automodels, Energy, Astronomy and Experimental Chemistry.
Reading time: 2 minute In this paper, addressed especially to vintage electronics enthusiasts, the principle of operation and realization of vintage electronic musical instruments is exposed, as well as the adjustment data.
