In order to provide my readers with more details about “how this project actually works,” I am providing this explanation that I call an informal review. There is nothing scientific about my test and review. Simply, it is just a simple set of measurements taken with my multimeter. There are quite a few variables (components) of this project that are affected by various environmental conditions, like, temperature changes, vibration, noise level, etc. I do my best not to measure, or look at every variable but keep it simple by only testing a small chunk that can be isolated and controlled in each test (and that is my best excuse for missing other important measurements).
