Real Inductors and a couple of real life stories about them.

The magnetic field around a coil of wire.

When I started down this path of talking about inductors in the post “Through the looking glass – Duality – The Inductor”, I chose to make a big deal about how the magnetic fields build and collapse. That was done for several reasons. First the magnetic

Inductors and Alternating Current and ELI the ICE man.

The rate of change throughout a sine wave cycle.

In the last posts about an Inductor, Through the Looking Glass – Duality -The Inductor” and “The Inductor – Part II” my goal was drive home the idea of duality: It is very similar but sometimes a mirror image of capacitor so I was jokingly

Solar Energy Book Review and Recomendation.

If you have followed my blog for very long, you have come to realize there are a lot of details on just about every subject. First you need to know the basic principals of the subject you working with, possibly some math, and then the critical things about the construction techniques and materials. Some of

Soldering Irons, Soldering Pencils and Soldering Stations.

A Cheap Soldering Iron

In the last post “Soldering – Construction of Electronics” posted a video about the skills of soldering. In this post I will talk about the tool necessary to do the job. I really do not have a recommendation, because the iron I currently use I would not recommend. I will

Soldering – Construction of Electronics

A Recent Built Electronic Kit.

We are getting very close to where “the rubber meets the road” in our electronics work. We have worked in design a bunch, but now we need to start talking about skills. There is no make of the create unless we make it. The first and probably in many

Calculating the “Hinge Boom” on the crane.

The angle from the cables to the new frame.

In the last post about the crane, “Using CAD in initial design – More work on the Popsicle Crane“, we determined all of the angles necessary to calculate the forces on all the beams and cables. In this post I will calculate all those forces

The Inductor – Part II

The Inductor circuit.

In the last electrical post “Through the Looking Glass – Duality – The Inductor“, I spent a lot of time building up the fundamentals of electromagnetism and what is going on inside the inductor. I also probably over-used the “twisted sister” analogy, but I will continue with that because we are
