A New Chapter for Contextual Electronics, Literally

Contextual Electronics is relaunching with an exciting new announcment. I will be the author of the fifth edition of Practical Electronics For Inventors, one of the most popular moderen electronic instruction tomes. The relaunch of the site introduces a faster, more streamlined experience for Contextual Electronics members, and introduces a new tier where community members can follow along and contribute ideas they would like to see in the book.

Practical Electronics for Inventors was first written and released in 2000 by Paul Scherz. It has become a much beloved tome of electronics knowledge, progressing with updates over the years and adding new features. Simon Monk took on the fourth edition and added new content in the digital domain and updated the text in 2015. I am now adding more hands-on content that will match the spirit of Contextual Electronics and introduce a new generation of students and hobbyists to this seminal work.

While there is still a lot to do and we are a long way off from teh release of the new book, there are so many changes in the electronics space I want to cover:

• Low cost manufacturing
• Open source design tools like KiCad
• New classes of parts
• New processing architecture like RISC V
• The impact of AI in the electronics space

That last one begs the question: A book?? With all this AI stuff happening?

Why a book?

A book does seem a bit...old fashioned, in the modern era. But that was likely said when radio, TV, and the internet were first introduced as well! I think the thing that excites me about this book is how it is used as a reference guide by so many, even past their first reading. It is well suited to pick up off the shelf to

So is this the book's website?

Contextual Electronics remains distinct from the book. I am not the owner of Practical Electronics for Inventors, merely its steward and new author. Furthermore, the book is not required to work on the course, and the course is not required to understand the book. Of course, I believe they will complement each other perfectly.

The Contextual Electronics website continues to have the course material from the inception of the course in 2014. Members can choose to go through the 20+ courses at their own pace, and build the projects that others have built over time.

What will change?

Contextual Electronics' hands-on, project-based approach remains core to the platform. You get video walkthroughs, applied projects, and real-world troubleshooting guidance. We're showing not just how circuits work, but why they matter and where they show up in actual products.

Some of the big changes involve:

• Updates to the tools, most notably moving to the latest version of KiCad (10, as of this writing)
• Adding additional walk-throughs of projects that look like the ones in the book's chapters
• Building in additional community features
• Improving feedback loops
• Adding peer learning—so everyone working through the material learns from each other.

As part of the relaunch of the site, we are switching to a centralize login service. This will allow members to tie their course login to their forum login, which was a pain point in the past. This is crucial to build up additional capabilites around the community.

Community Involvement and a new Tier

As I discussed working on the book with the folks at McGraw Hill, I was excited to do what I have always done: Work while others are following along. This is a key piece of Contextual Electronics. Throughout the years we have developed courses and worked with community members to improve and refine content over time. This time is no different.

We are introducing a new $1/mo Book Community tier to give access to the newest content as it is developed and a private section on the Contextual Electronics forum. This will allow users to peek in on content as it is developed, and ask questions and direct the future content that is made. For example, as I design and build the board that is part of the first chapter I am developing for Practical Electronics for Invetors, members of the Book Community can watch as I post each new video. Then on the associated forum post we can discuss the merits of one methodology over another, and I may even ask for community feedback on a new feature to include. This will form the basis of the book content in the first chapter and beyond.
