Summary of the standard op-amp amplifiers

The Op-Amp Circuits under test.

We have went through a lot of information about the standard Op-Amp amplifiers so before going on and complicating things even more it is time to summarize what we have learned. To keep things as practical as possible I will do this from the point of view of the

A new LibreCAD tutorial – toolbars and the divide function.

I am self taught on LibreCAD although I have used other CAD programs. I have learned some things since the first tutorials that can save some keyclicks. I think I have one more tutorial coming on these miscellaneous functions and then I will spend some time creating some blocks and show as much about the

Column Buckling – Length, Radius of Gyration, & Elasticity

Rubber Columns just don’t get it done.

It this post I am going to try to tie together all of the recent posts about the forces on beams, moment of inertia, and the stress-strain curve. This is an overview and not number crunching like the last post. Since we are dealing with unknowns with

A LibreCAD tutorial – miscellaneous topics part 1

Tonight I posted a new YouTube video – Another LibreCAD tutorial. This one cleans up a mistake I made earlier and explains a button that can cause some problems with the hatch function and probably has a bug associated with it in relation to the line types.

I also explicitly explain some of the tool

The Resistance seen by the Op-Amp in our circuits.

The Op-Amp Circuits under test.

Thankfully we are through with the heavy meals of Op-Amp theory for awhile. Tonight’s post will be a full meal but nothing like the last one. We will not have to loosen our belts, walk around the parking lot a few times and move the seat in the car

Op-Amp Current and Voltage Offset

No Chip (or man) is an island.

In the last post on this subject, “Our Op-Amp Circuits Input Impedance“, I mostly talked about the the outer two squares on the diagram to the left. Today we will talk about the two inner squares on the diagram. This is some of the things I kind

How Our Craft Stick Beams Resist Bending.

Four 2 X 3 Popsicle Columns

Cross section view of possible craft stick beams.

The problem we have with the craft sticks and bending is bending in the thin direction (axis). The answer I have come up with is stacking the sticks to get a wider beam in that direction as shown in
