I would like to offer some constructive criticism.
I often see on this forum that the people who are very experienced on a topic give teasing responses. I don't understand the point of that.
For example, Tautech sends three replies in a row essentially saying that you need to search better, that you haven't done enough.He could have simply explained the hardware differences right away. He dit not help in any way but he had the answers looking for.
TV84 says for example that you need to read better through the large amount of text. I find that unfortunate. Personally, I always try to provide someone with a helpful answer and not belittle them.
Let me finish by saying that I appreciate the wealth of knowledge here, but it could sometimes be a bit more friendly.
In this case let me offer you an insight to the other side:
Some of these are questions answered already hundreds of times.
It gets old to do due diligence for other people that are too lazy to do their own work and learning.
As for beginners that ask an honest question without knowing, they also need to be set on path of learning how to learn.
Reading documentation is very, very, important part of electronics.
Learning to do it is best as soon as possible.
OTOH, a person saying:" I read that this SA has this parameter and other one has something else, could please someone try to explain it to me what it means.." will generally be met with many people trying to help.
A certain amount of demonstrated homework done is prerequisite before asking for help with learning.
Nobody here is paid for support.
Tautech is from New Zealand. Any help he provides to the rest of the world is just his good will in his free time. Same with everybody else.
And, yes, people are also grumpy sometimes... We are all only humans..
