In an effort to better focus the material, make the best use of lab resources, and reduce book costs to students; a series of textbooks and laboratory manuals have been developed at MVCC for use in our Electrical Engineering Technology and related courses. These replace the formerly used materials which, in some cases, were over $200 each, in paperback. A description of the collection can be found here. The materials listed below are available to anyone, free of cost. The following titles are copyright by the author, Professor Jim Fiore, and use a Creative Commons license. The author thanks the MVCC community for their support of these projects. PDF is the ".pdf" portable document format version, ODT is the ".odt" open document text format which is editable by Open Office and other word/document processors, HTML is an online version (thanks to LibreTexts), and PRINT links to Amazon for a printed copy at a very modest price. For e-book and other formats, consider using Calibre for conversions (see software links under OER From Other Sources below for descriptions, or just go here: Open Office  Calibre).

There is a YouTube channel for videos supporting these texts, Electronics with Professor Fiore: https://www.youtube.com/ElectronicsWithProfessorFiore
It's a work-in-progress right now thanks to Covid-19.


Sample Wrench is an extensive digital audio analysis and editing tool that runs under Windows. Formerly a commercial product for many years, I recently placed this as non-commercial redistributable freeware. It is useful for coursework in electronics, audio, acoustics, music production and the like. More information about it can be found here (these links will take you to my other site, dissidents.com). This software is used in PH106 Science of Sound and can be useful in AC circuits and electronics courses.

Soundcard Oscilloscope (Windows) uses your soundcard (mic/line input) to create a dual channel oscilloscope suitable for audio frequencies (sines below 20 kHz, square waves below a few kHz). There are other limitations set by the sound card, namely, a limit on the maximum input amplitude and potential issues of excessive loading due to the input impedance of the audio circuitry (probably just a few kilo ohms), but it's worth a look. Also generates sines and other waveforms via the soundcard output. You'll need to buy/make appropriate cables (typically computers use 1/8" stereo plugs). Free for educational use: https://www.zeitnitz.eu/Scope_en

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) :  http://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.

Calibre is an extensive e-book format converter and manager. It is free, open source, and runs on Windows, Linux and MacOS. Convert your PDFs into Kindle, Nook, EPub, and other formats.

SciDAVis is an excellent, easy to use, free, multi-platform (Windows, Linux, MacOS) data plotting and visualization application.

Octave is a mathematical tool very similar to Matlab. It uses the GNU Public License and runs on Windows, Linux, MacOS and BSD. 

If you need graph paper for your courses, here is a utility that generates several different kinds of graph paper using your printer. It runs under Windows. This is a self-extracting zip file (about 400k): gpaper.exe You can also create your own graphpaper online. For three cycle semi-log landscape paper go to http://www.incompetech.com/graphpaper/logarithmic and set paper to other (11 x 8.5), x axis to 3 cycles, and y axis to linear. Try 4 lines per inch and include fine lines. Other kinds of paper are available also.

XnView is a graphics file viewer and editor. Free for non-commerical use, it is great for manipulating the image files that are generated by the digital sampling oscilloscopes in labs AB216, AB218, AB286, etc. (such as scaling, rotating, color inversion, etc. for insertion into lab reports). It's also good for doing screen captures so that you can grab the circuit and analysis windows of circuit simulators and insert them into reports. This is much more powerful than MS Paint.

You may wish to download this free "Virtual Minirator" sound generator software (Windows). This uses your computer's sound card to emulate an NTI Minirator (similar to what we have in lab). Useful for Circuits 2, Linear, Op Amps, Science of Sound, etc.

Python is used in ET154 Computer Programming. Powerful, free, and multi-platform.

Pelles C is a free C compiler used in ET283 Microprocessor Fundamentals. The Arduino software for this course is available here.

In a culture that seeks to monetize everything, creating something of value and then giving it away is a subversive act.
