Transformers – Part 2

Old Smokey – 70 VA transformer.

Tonight’s post is relatively short compared to last night’s post. Last night I wanted you to really understand how the load on the secondary is reflected back to the primary through the magnetic coupling. It was primarily about concepts. Tonight’s post will talk about one other function transformers

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

An overview of heat solar collectors.

Solar Energy Concepts

In the last post, “Where is the biggest bang for the buck in solar energy?” , I hope the data was convincing that the best place to use your time and money is toward heating your house and possibly the hot water you use. Tonight’s post is going to work from

Episode 49 – Some more about heat radiation

In this episode I talk about a lot of general things and specifically about heat radiation.

I kind of went all over the road in this episode and started with a rant and funny story about the divisions happening among people here in the US and actually the rest of the world.

I did get

Episode 048 – Heat ,Thermodynamics, and Insulation – Part 3

5 TO 1 FT DIA

In this episode we review the difference between heat and temperature, state the laws of thermodynamics and how heat is transferred and then finally move on to insulation.

To further explain the difference between heat and temperature, I make the analogy of two tanks as show in the following two pictures. In the first picture

Episode 047 – Heat ,Thermodynamics, and Insulation.

This episode is primarily dedicated to heat and heat transfer. Building upon the previous episode the concept of heat and temperature are discussed some more. Using a water analogy, heat is similar to the volume of water in a tank and temperature is similar to the height of the top of the water in that
