Several Announcements and another Qucs Video.

Qucs video Part 5

This post is an announcement of several things. As usual I am going to change direction for awhile for several reasons. First the Big Announcement. Create-and-make is the featured website for this week on an outstanding Website for the Electrical Engineering Community, EEWeb.com, A link to the feature and the

Qucs – Documentation, the Net List, and the Component Library

Title screen of the new video.

I hope by now I have many of you interested in using Qucs for simulating electronics circuits. This is another blog wrapped around a video I have posted. I still do have my “love – hate” relationship with simulations. You can do a lot very quickly with simulations,

Circuit simulation software – Qucs

A Simple model in Qucs

I spent a fairly large about of time trying to find some simulation software to meet the needs of this blog and the readers of this blog. Some of the criteria I used in the search were:

Free or very low cost: Most of us do not have hundreds

Drawing the Schematic for the Desulfator in Kicad.

The Desulfator Schematic in KiCad

HAPPY NEW YEAR! Usually this time of year I think about what I accomplished in the last year and also where I want to go in the next one. I have been so busy this season that I really have not given it as much thought as usual. However,

LibreCAD Tutorial – Adding Blocks to the Parts Library

A small library of nuts

In this tutorial we are taking the library of nuts we have created the final step and adding them to the Library Browser. Although this sounds as if it is a minor step there are a lot of gotcha’s and things to think about. Foremost of all is as

LibreCAD Tutorial – Building and Using a Library of Parts.

Finally we are to a point of building a library of parts to use over and over in different drawings. In this video I show one way of using a library of those parts in your actual drawings. I call this the cut and paste method. In the next video I will show you

LibreCAD Tutorial – Using Blocks Part 2

This is a continuation of the previous post: Using Blocks Part 1. Many modify functions in LibreCAD work fine with blocks. These functions such as trim, scale, copy, and mirror do not affect the block. However, functions such as round, bevel, & stretch would modify the block so those cannot be used with blocks. Please

A new LibreCAD tutorial – Blocks Part 1

No. 6 Nuts

When designing a project, often the same things are used over and over. It is good to have these available for easy insertion into a drawing. These are called blocks in CAD and can be thought of similar to “rubber stamps”. These are helpful, but some planning and thought must be

The Incredible Shrinking Drawing and a Good Website.

Tonight’s post will be very short, but it actually will be about two subjects. First I am embedding a new video I have created about CAD. Second, I am going to recommend a web site about electrical and electronics theory.

Some co-workers told me about the website All About Circuits. The site is very well

Using Manufacturers drawings in LibreCAD

A manufactures drawing being used in LibreCAD

Many manufacture’s have dxf files of their products available for download. These can be used in LibreCAD as well as the high-priced proprietary CAD programs. In the embedded video I show how you can download and use these files for components in your projects.

The example I
