The Thermistor Board is Calibrated!!!

Final Calibration.

The Thermistor Circuit Board is Calibrated! I was able to successfully calibrate it at 0 deg C and 70 deg C. Now is the time to think about what went right, what went wrong and what is the next step, both for this blog and with this project.

What Went Right!

First,

Update on testing the thermistor circuit board.

The final version of the circuit.

All the troubleshooting is complete and the circuit is working well. They say experience is the best teacher… just too bad it comes too late. My dad has a related saying: “Experience is the best teacher, but it is a heck of a lot easier if it is

The Thermistor Circuit is Complete. Finally!

The Final Thermistor Circuit.

Because of the loose tolerances used in electronic components designing circuits is not as easy as it sounds if you need close tolerances on the final circuit. Adjustable components and some sort of calibration procedure helps and are necessary, but making sure those adjustments can cover the complete range of

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

Where is the biggest bang for the buck in solar energy?

Solar Energy Concepts

Tonight I thought I would start pointing the direction we will be going toward solar energy. Like in all projects the first thing to determine is where do we want to go. I am going to make the first assumption. We want to use our money in the most effective way

The Thermistor Circuit and Zener Diodes.

The Thermistor Circuit.

The thermistor circuit is complete! There are a few resistor values I want to check before I show all of of the values, but essentially the circuit is complete. This circuit will do everything we described in the last thermistor post, “One More Step Closer to Completing the Thermistor Circuit”. There

One more step closer to completing the Thermistor Circuit.

Block Diagram of the Thermistors.

In Basic Training in the Army there is a very steep hill you have to march up. Just as you think you are at the top of the hill, you realize it was not the top at all. It was a curve and as you round it there is

Goals of Calibration of the Thermistor Circuit.

Block Diagram of the Thermistors.

Tonight is time to zoom out and look at the block diagram of the thermistors. When drawing a CAD drawing it is necessary to sometimes zoom in and work with details and sometimes necessary to zoom out and look at the overview. When designing parts of a process to
