“If we did not have ICs then this is what a 7400 NAND gate would look like! The 7400 TTL (and LS-TTL) quad NAND gate is one of the most common integrated circuits (IC) around. Here is a discrete …
“This book contains both simple and more advanced projects, and it is hoped that these will be found of great help in developing a knowledge of the workings of digital circuits. Various forms of assembling and wiring the integrated circuits …
“Considering that it offers a solution to many current problems, today I am continuing the discussion concerning the ESP32 LORA, a marvel for this Internet of Things world. In this article, I deal again with safety when discussing an infrared …
“This handbook describes in detail a wide range of electronic circuits designed around that tiny but versatile modern device, the transistor. The arrangements described have a great variety of practical uses. Some of these circuits derive their power solely from …
“The IOT123 BRICKS are DIY modular units that can be mashed up with other IOT123 BRICKS, to add functionality to a node or wearable. They are based on the inch square, double-sided protoboards with interconnected through holes. This BRICK adds …
“Chemnitz University electrical engineers are the first in the world to print electric motors using iron, copper and ceramics Using metallic and ceramic pastes, extruded layer by layer into a predetermined form and then sintered together, researchers from the Chemnitz …
“ One way that scientists control the structure of materials at the nanoscale – where features are a few to several hundred nanometers (nm) – is by using “self-assembly,” in which molecules are designed such that they spontaneously come together to form a …
“A current area of intense interest in nanotechnology is van der Waals heterostructures, which are assemblies of atomically thin two-dimensional (2D) crystalline materials that display attractive conduction properties for use in advanced electronic devices. A representative 2D semiconductor is graphene …
“Researchers have shown that certain superconductors – materials that carry electrical current with zero resistance at very low temperatures – can also carry currents of ‘spin’. The successful combination of superconductivity and spin could lead to a revolution in high-performance computing, by …
“The use of semiconductors in electronic circuits has, and still is, growing at a rapid rate. Experimenters and hobbyists are continuously looking for transistor circuits to construct. This book is a compilation of many r -f and audio circuits using …
