The Modular Electronics Learning (ModEL) project represents the culmination of nearly two decades of professional instruction in the field of industrial electricity and electronics. It is substantially different from earlier publications such as Lessons In Electric Circuits in multiple ways. First, the tutorials seek to explain as much as possible about electric and electronic circuits from first principles such as physical Conservation Laws, while remaining at a mathematics level below that of calculus. Second, the tutorials seek to be self-contained, each one beginning with a brief review of necessary background topics. Third, question sets, projects, and experiments are contained within each module, designed to challenge students to apply the concepts and procedures taught in the corresponding tutorial. Fourth, these application questions specifically address qualitative, quantitative, and diagnostic modes of thought in order to encourage well-rounded development of the learner's understanding.
Similar to my Socratic Electronics project, the modules contained here are expressly designed to be used within an instructional modality that is both ``inverted'' (students learning independently through reading prior to meeting with the instructor) and ``Socratic'' (the instructor challenging students to reason through all concepts and problems via dialogue).

Start at the top, and work your way down.
Modules in the same row may be completed in any order. Ideally, you should complete each whole row before proceeding down to the next row.
A reasonable pace for a full-time student in a learning environment where these modules are reviewed on a daily basis with an instructor is two days per module.
Any module titles appearing in italic font are either incomplete (if hyperlinked) or are not yet created (if unaccessible).

SPICE version 2G6 is a legacy, ``freeware'' program used to analyze DC and AC circuits. Using SPICE is similar to writing a computer program. The first step is to create a plain-text file containing instructions for SPICE to follow, and then you invoke the SPICE program to process that plain-text file. SPICE then generates readable output with an analysis of the circuit, either in plain-text form of in a format suitable to graphic display using other software applications. While this may seem primitive in comparison to ``WYSIWYG'' style circuit analysis programs where you draw a picture of the circuit to be analyzed, using SPICE to analyze simple circuits is far from complicated, and becoming familiar with writing SPICE code is an excellent introduction to text-based computer programming, which any serious student of electronics needs to learn anyway.
Here is SPICE2G6 compiled for Microsoft Windows XP, to be run in the command-line window (cmd). This is a precompiled set of executables and dynamically-linked libraries: spice-2g6-winxp.zip
Here is SPICE2G6 for the Linux operating system. After unpacking this ``tar.gz'' source code archive file, you will need to compile it to create an executable: spice2g6.tar.gz
A more modern version of SPICE is NGSPICE, the particular version hosted here is version 26. This is a derivative project based on SPICE version 3, copyright (1996) by the Regents of the University of California under a modified BSD license. A user's manual complete with all copyright notices and licenses is avaiable here: Ngspice version 26 manual (PDF)
Here is NGSPICE version 26 compiled for Microsoft Windows. It comes with an interactive terminal and graphic display. Simply extract all files contained in the ``zip'' archive: ngspice-26_140112.zip. Instructions for using the interactive mode are found in the manual. NGSPICE also supports legacy ``batch'' mode operation as well, where you invoke NGSPICE at the command prompt (cmd) and receive text output.
Here is NGSPICE version 26 for the Linux operating system. After unpacking the source code archive file, you will need to compile it to create an executable: ngspice-26.tar.gz.
This is the ``archive'' file for the Modular Electronics Learning project, in ``tar'' format which is a popular archival format on Unix-based operating systems: model.tar
