Sinusoidal waveforms, AC, and DC signals.

A sine wave

The whole purpose for almost all electronics is to modify changing signals. Even in the case of our thermistor circuit, there would be no reason to be interested in the temperature if it did not change. This is our introduction to signals and AC.

The type of waveform that is always

Parachute Cord and Popsicle Crane Analysis

Face View of the Spring Scale

I spent some time analyzing the good the bad and the ugly of the popsicle crane boom test and there was some of all three. The main problem was the parachute cord stretching but I also did not have the angles I thought I did. First, the issue

Energy Storage – Capacitors – Equalization of Pressure

A Low Voltage Electrolytic Capacitor

In electrical theory we have so far been dealing with unchanging or very very slowly changing values. Tonight’s post is the start of talking about changing values of current and voltage. We are still talking about Direct Current, but we are starting to change the course of the path

Test 2 of the Popsicle Crane Boom.

The crane boom.

Last night I tested the crane boom and the video has been published. The boom did a great job. The cables did not. I used paracord for the most stressed cables and it turns out that paracord is very elastic and I was not able to maintain the angle of the

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
