I have written a lot of on electret microphone connections on my Powering microphones document. Here are some additions to my documents on electret microphones I found at SANKEN Basis of Wiring Method web page. The first circuit diagram shows the traditional “2 wire” method of wiring an electret capsule. Practically all electrets I have →
Some days ago read Things Every Electrical Engineer Should Know about EMC slide set by Todd H. Hubing Michelin Professor of Vehicular Electronics Clemson University. I must say that it is an interesting slide set to check. It is a short 25 slide set that introduces EMC fundamentals and ground loops. Here is one fact →
Modern automobiles are no longer mere mechanical devices; they are pervasively monitored and controlled by dozens of digital computers coordinated via internal vehicular networks. Experimental Security Analysis of a Modern Automobile report experimentally evaluates these issues on a modern automobile and demonstrate the fragility of the underlying system structure. The paper demonstrates that an attacker →
Nikola Tesla was an inventor and a mechanic and electrical engineer. He was one of the most important contributors to the birth of commercial electricity. In the field of electrical engineering, Tesla enriched the world with more than 700 registered inventions, many of which were so far in advance of their times that they could →
Crimping without a crimp gun video tells how to install a 0.1″ crimp connection with pliers if you don’t have a crimping tool. If you don’t have many connections to make this method works OK. I have used similar methods myself. When you need to make many connections, it is a good idea to invest →
May 11, 1951: RAM Is Born article tells Jay Forrester files a patent application for the matrix core memory that day. A team at Massachusetts Institute of Technology led Jay Forrester developed a three-dimensional magnetic structure code-named Project Whirlwind. In short, magnetic core memory was the first random access memory that was practical, reliable and →
It has been hard to miss the story of the Apple engineer who left a rumored prototype of 4G iPhone at a beer garden. Some time later Gizmodo got hold of that 4G iPhone and posted a report on it on-line (interesting stuff). Scott Adams, the man behind Dilbert comic has made a two comic →
You might know my Time Domain Reflectometer (TDR) signal source circuit published on ePanorama.net many years ago. It has worked well for me many times. Some years ago I made a modification to my own TDR unit. This simple modification allows me to use the same box also as a signal source with a wide →
Imagine, putting on a glove and you can play the piano. Colorado State University students have created such a glove that detects the bend of a finger and plays a corresponding piano note. Gadget Freak Case #162: Magic Fingers Tickle the Ivories article tells you the details of their design. There is also a video →
I have been posted many articles related to LED lighting. And I think I will post more articles related to this quickly evolving field of electronics. So I created a category LEDs for all articled related to LED technologies. →
