My colleague Bill Hunt wrote a nice OER lab manual for introductory digital electonics, Digital Electronics Laboratory Manual:   PDF   DOCX

Here are some open and/or free items that I can recommend. I have used these for my coursework and to create the books and videos listed above.

You don't have to use MS Office! Here are two good office suites that include a word processor, spreadsheet, graphics, etc., and best of all, they're free, open and multi-platform (Windows, Linux, MacOS) :  https://www.openoffice.org/ and https://www.libreoffice.org/. I use Open Office for most of my work and it's the primary tool I used to create my OER texts.

SciDAVis Scientific Data Analysis and Visualization is an excellent, easy to use, free, multi-platform (Windows, Linux, MacOS) data plotting and visualization application.
XnView is a graphics file viewer and editor. Free for non-commerical use, it is great for manipulating image files.
TINA-TI DesignSoft's free circuit simulator, runs under Windows.
Dia Diagram Editor A nice tool to create diagrams, simple graphs and the like.
OBS Open Broadcaster Software is great for a variety of video needs including creating instructional videos that use your computer desktop.
fre:ac A free audio converter. A useful companion for my free Sample Wrench audio editor/analyzer.

    A Note From the Author

Hi. My name is Jim. I've been a college professor for 40+ years teaching in the areas of electrical engineering technology, computer programming and the science of sound. Along the way I've won a few awards for my efforts (State University of New York Chancellor's Award for Excellence in Teaching, SUNY Chancellor's Award for Excellence in Scholarship, and others). I'm also a musician and an endurance athlete. I established dissidents in the late 1980s as a way to offer various software items that I created, figuring that other people might find them useful as well. Some of these have been commercial and some have been freeware. I also write a lot, including published college text books and lab manuals. Recently, the open educational resource movement has gained momentum (no doubt at least partly propelled by the rising costs of college tuition and texts). As I am no supporter of the growing "corporate-ness" in our society, nor a believer in the dogma that unfettered free market capitalism is the answer to all problems, I decided to do the dissident thing and offer all the titles here free. This includes all of the above technical titles which, if offered by a traditional college textbook publisher, would be fetching in the neighborhood of $100 for a lab manual and over $200 for a text these days. It is my hope that others will do likewise, all of us offering something of value to the community, improving the situation for everyone. An appropriate quote comes to mind:

"We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on."
