I have seen on some YouTube channels procedures for testing components and circuits in addition to assemblies that do not seem reliable. How can I know if the material presented is consistent?
Indeed, on Youtube channels there are many videos made by people who do not have technical knowledge that can be said to be good enough to explain what they do, or even, to do things correctly. Some aberrations are common, aiming precisely to "deceive" people with even dangerous procedures or even tricks that can make things work in the video, but not in practice. We saw the case of a trick in which a potato LED is approached, and it lights up indicating the presence of dangerous radiation. Obviously, whoever has a minimum of technical knowledge does not fall for this. However, there are some videos that indicate more advanced procedures such as testing and assembling circuits that are more difficult to evaluate by those who do not have a firm base in electronics. What to do in this case. Do not trust everything. Look for other sources if you have questions and even write to us, as we can help.
