Genrad – General Radio – Instrumentation

History and accomplishments of the General Radio Company, one of America’s first equipment manufacturers for the radio and electronics industry.

General Radio Historical Society

Founded in Cambridge, Massachusetts in 1915, GR provided the tools and instruments that allowed the electronics industry to burgeon into today’s giant that fills our lives with radio, TV, computers, cell phones, DVDs and all the other electronic products in our homes, businesses and automobiles.

General Radio Experimenter

This pioneer publication first appeared in June 1926 and became the model for many others to follow (most notably the HP Journal). It began with engineers talking to radio amateur customers and gradually changed to engineers talking to other engineers, who might also be customers.

Circuit Cellar – The Magazine for Computer Applications

Since its founding in 1988, Circuit Cellar has delivered exactly what its paying subscribers demand-intensive, exploratory articles about hardware and software methods for embedded-control systems.

Circuit Cellar – The Magazine for Computer Applications

Circuit Cellar Ink, the best magazine devoted to hardware and embedded computer development, or “What’s Inside the Box”.

Index to Circuit Cellar Ink – Dave Tweed

“By joining forces with Elektor International Media in 2009, we’ve taken the meaning of “global contest” to new levels. Engineers hail from the U.S., Germany, Netherlands, France, Spain, India, and more, to see who has the most skill and ingenuity to take their design ideas from an innovative concept to a winning solution!”

Portable Power Quality Meter

“The Portable Power Quality Meter uses an RL78 MCU to read power factor, total harmonic distortion, line frequency, voltage, and electrical consumption information and stores the data for analysis.”
