Graphical Construction: Drawing a circle tangent to other circles

An actual problem solved. The build of wire making a coil

Tonight’s post is a graphical construction that does not have a built-in function in CAD. Drawing circles tangent to other circles was an actual problem I had to “go back to the books” to solve a problem. The picture to the left is

LibreCAD Manuals and Some Good LibreCAD Links

A long time viewer of my LibreCAD videos and one of the first people to subscribe to this site sent me an e-mail this weekend informing me of two manuals available for LibreCAD. In addition I am providing some links to some good sites that contain forums about LibreCAD.

The links to the manuals are

The Mechanics of a Loudspeaker

The cross section of a Loudspeaker

In the last loudspeaker post, “The Electrical Part of a Loudspeaker” we “divorced” the mechanics from the electrical part of the speaker. But like good divorce judges we are now going to listen to the other side of the story. The picture to the left shows a cross

Our First Motor – A loudspeaker.

The dross section of a Loudspeaker

It is time to get back into some theory. Almost any project will end up producing some kind of mechanical motion so the understanding of electrical motors and magnetic devices is very important. My way of learning and teaching is to learn one thing very well and then
