How to Build Logic Gates Using Transistors?

This is a continuation of previous blogs about logic gates. Earlier you read about logic gates and their functions. Then you read about how to code logic gates in Verilog, VHDL, and C. Now its time to learn about creating logic gates with transistors. After reading all of these posts you’ll have learned about logic gate theory, coding logic gates in both hardware and software, and the physical hardware design of logic gates.

Plasma Arc Microphones

In a previous post, I talked about how plasma can be used to build high-fidelity speakers. Plasma isn’t limited to only producing sound– it can also be used to record it. Being made up of physical particles, plasma can be affected by vibrations through the air. This means it is possible to build a plasma arc microphone using the proper circuit. This application is far less common than using a plasma arc for a speaker, but research has still been done on the subject.

Women’s History in STEM

As I mentioned a couple days ago, we will have a greater focus on women’s history within STEM this month. Last summer, I did a blog series focusing on just that! With it being the beginning of the month, I’d like to do a throwback to one of my first posts in the series that provided an overarching history of women’s involvement in the long history of science, technology, engineering, and math.
