https://archive.org/details/bstj-archives The scientific discoveries and technological innovations produced by Bell System research and engineering were critical not only to the evolution of global telecommunications but, more widely, they had a considerable impact on the technological base of the global economy. The invention of the transistor at Bell labs in 1947, and subsequent advances in related →
https://www.edn.com/electronics-blogs/si-pi-masterclass/4461028/Make-simple-fixtures-from-SMA-connectors For testing SMD components you need some test fixture. A fixed-geometry fixture produces consistent and repeatable results. This article tells how you can easily make fixed-geometry fixtures out of PCB-mounted SMA connectors. You can build a fixture to measure bypass capacitors using SMA-female edge-mount connectors. The narrow-base connectors (5 mm grid) and are best →
https://www.edn.com/design/analog/4461000/A-technical-performance-based-view-of-opto-isolators-and-digital-isolators Galvanic isolators are devices that couple an electrical data or control signal across an insulation barrier without any flow of current through it, thereby enabling signals to be transferred while blocking noise. The insulation barrier also safeguards equipment and human operators from high voltages. The earliest isolators were optically coupled devices, also called opto-isolators →

https://spectrum.ieee.org/semiconductors/devices/july-1958-kilby-conceives-the-integrated-circuit In 1958, 11 years after Bell Labs reinvented the transistor, it became clear that semiconductors would be able to conquer the electronics market only if they could be greatly miniaturized. In July1958, Jack S. Kilby of Texas Instruments came up with the monolithic idea. In January 1959, Robert Noyce was to jot in his →
http://www.electronicdesign.com/analog/what-s-all-prank-stuff-anyhow Who says engineers don’t have a sense of humor? Remember the WOM, inspired partly by the Umac 606 phantasatron? The DEAD diode? Many of the early analog electronic greats were inveterate pranksters – and sometimes the prank made the papers and history. This article tells the story of some famous electronics design pranks. →
