via HACKADAY: Scribble Your Way To Quick Printed Circuit Boards

There are a variety of techniques employed by electronic constructors seeking the convenience of a printed circuit board without the inconvenience of making a printed circuit board. Dead bug style construction in which the components float on a spiders-web of soldered leads above a ground plane is one, Manhattan style construction in which pads made […]

via HACKADAY: The components are INSIDE the circuit board

Through-hole assembly means bending leads on components and putting the leads through holes in the circuit board, then soldering them in place, and trimming the wires. That took up too much space and assembly time and labor, so the next step was surface mount, in which components are placed on top of the circuit board […]

Cornell has a radio for the whole world with software filtering

Researchers at Cornell University have developed a new type of radio-on-a-chip that could mean cheaper, more flexible wireless systems. Smartphone makers could, for example, use the technology to make a single model of each phone that works anywhere in the world. Single-chip radios have become a popular choice for communications hardware in the last decade […]

ARRL Reintroduces a Popular Classic — Experimental Methods in RF Design

ARRL has reintroduced the popular title Experimental Methods in RF Design as a classic reprint edition. Immerse yourself in the communications experience. Build equipment while understanding basic concepts and circuits. “This is a…classic, extremely good text on designing circuits for the ham,” ARRL Life Member Bob De Varney, W1ICW, a professional radio communication technician and […]
