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.

iLAB Analog – Practical Introduction to Analog Circuits

During the Christmas break, I ended up reading iLAB Analog, a new textbook written by Dr. Chen Yun Chao from National Taipei University of Technology Department of Electronic Engineering. I was excited to read a book that deals with both conceptual knowledge and has practical labs. For anyone who wants to learn about analog circuits but has very basic knowledge of physics, it is a good starting point. This book is currently being used in the Intro to Analog Circuits class held at National Taipei University of Technology.

How Do I Use Digilent Products at School? (Digital Edition)

As you learned from my previous post (the Analog Edition version of this post), we used the Analog Parts Kit and Analog Discovery in EE352 at Washington State University (WSU) to make an AM radio transmitter and receiver. Not only do we use Digilent products in EE352, but we also used Digilent parts in EE324 (Fundamentals of Digital Systems) — the digital lab class I was taking.
