“Ultimate Electronics” is a Free Interactive Electronics Textbook

The creator of the CircuitLab simulation software, now used in electronics courses at MIT, CMU, and other top universities, has just released the first few chapters of a new book. It’s called “Ultimate Electronics: Practical Circuit Design and Analysis,” and it’s available free online. It’s interactive because every schematic in the book can be clicked to open it, and many have a simulation that can be run and changed right in the browser.

How to Read Your First Autodesk EAGLE Schematic

Back to basics. Here is a tutorial on autodesk.com blog on how to read schematics:

The schematic forms the building block of every electrical circuit, and even if you aren’t designing one yourself, knowing how to read one is invaluable. And with some schematic reading knowledge in hand, you’ll be able to design, build and ultimately troubleshoot your way through your design logic before heading on to your PCB layout.

EAGLE Is Now Released By Autodesk

After acquiring CadSoft in June 2016, Autodesk released a new version of EAGLE with new features that improve program functions and a new pricing plan.

The new version of Eagle added a modular design blocks feature to the schematic editor that allows you to quickly replicate sections of circuitry between multiple projects. Even better, any change you make stays synchronized between your schematics and PCB.

The route engine comes with new, interactive routing features that make it easy to design beautifully precise PCB layouts. It includes a whole set of trace clean-up tools that makes it much easier to tidy up your board and make adjustments to existing paths. There is also an automated loop removal, cornering for super-smooth tracks, quick and easy via placement while routing.

Autodesk said that upgrading EAGLE will be available as a monthly or yearly subscription, providing continuous updates and better support, and it said to be budget friendly. Which means that users will get more consistent and frequent updates backed with dedicated support from the PCB design pros at Autodesk, and cheaper than buying a cup of coffee every day for a year.

Eagle Pricing Table

Many Eagle users found it a bad deal, because having the old Standard option will cost $100/year instead of the one-time $69 payment. Autodesk also killed the lower cost options for non-commercial use, what used to be a $169 version that was positioned for hobbyists.

“We know it’s not easy paying a lump sum for software updates every few years. It can be hard on your budget, and you never know when you need to have funds ready for the next upgrade.”

You can download the free version from here, but for anyone using Eagle for commercial purposes this is a big change. Even if you agree with the new pricing, a subscription model means you never actually own the software. This model will require licensing software that needs to phone home periodically and can be killed remotely. If you need to look back at a design a few years from now, you better hope that your subscription is valid, that Autodesk is still running the license server, and that you have an active internet connection.

KiCad appears as the alternative software for Eagle users, and many of the PCB designers planned to start using it as it has been improving steadily in the past years.

Eagle CAD Tips and Tricks

cmdEagle

Most hobbyists and many professionals use Eagle CAD as a daily tool in designing schematics and laying out PCB. Yahya Tawil is going to share with us the most important tips and tricks for using Eagle CAD, which make your work much easier and faster.

My advice is to keep one hand on the mouse to do wiring, etc. inside the editor workspace and use the other hand on the keyboard to write commands and select tools. My advice of using the keyboard is not only for selecting tools. You will see the other benefits of using the keyboard in Eagle CAD in the rest of this series.

Search Github projects by component – find design references

search_github

dangerousprototypes.com has launched a new search feature that is able to search GitHub for specific parts and enables you to easily find reference designs for your next projects. This new search feature can also display Schematics and PCB previews without having to open a CAD software on your local machine, but some limitations exists. They write:

TomKeddie first mentioned this idea at Hacker Camp Shenzhen, and later in the forum and on WeChat. Tom generously shared his scraping/search method. Eagle 6+ files are XML, so we can find them on Github by searching for the “eagle SYSTEM” tag in files with “extension:sch”. That gives more than the maximum 100 pages of results, so we filter by file size and increment size 500 bytes at a time “size:1001…1500″. We use the normal user search interface, parse the HTML results, and grab all urls ending with .sch. While Github has an API, that API doesn’t give access to search code search without specifying a repository by name (probably so people don’t do what we did…).
