Very basic beginning electronics

I would like to see some interest in basic, for beginners... like:what
does a diode do, and what is it for; what is a transistor and what is
the difference between a PNP or NPN.
Anybody interested in hobby electronics , maybe kit design and
building. What say you all about something like that?

Google will find you all sorts of information on any of
those things (remember to add the key word [tutorial] to
your searches).

If you find something that is confusing or leaves a nagging
question, this group might be the place to get help with
that. But this discussion forum is not the best place to
hold classes.

The subjects you mention are NOT for beginners. Be with
electric/electronic hardware for few scores of years and it will dawn on
you. "Designing" a kit for someone else to build is an art by itself.

Good luck.

Agreed. Books and web pages are fine as one-way conduits of
information. What this newsgroup does is add another important
dimension, two-way conversation. Learning well often involves two way
interactions. This is one place to get some of that. Books and web
pages are great for various attempts at explanation in a one-way
setting. Start there. Then ask questions as they arise, here.

I don't know, I kind of skipped all that and didn't get lost.

I think too many here are reading too much into the post.
"Difference between a PNP and NPN" could simply be wanting to
know what polarity goes to their collector. "Diodes allow
current to flow one way", and they are commonly used to rectify
AC voltage to get a resulting DC voltage.

One problem is that the hobby electronic magazines have gone away.
They used to be the introduction to the hobby, and people could build
things without needing to know much, yet the practice of drooling over
the schematics and reading the "how it works" section of the article helped
to raise their technical ability. And those practical examples were
the impetus for seeking out more detail in the books.

There is a lot of "basic" informatin that one accumulates that way that
has little do with "understanding" yet in effect does help to bring
understanding.

Obviously if someone is asking such vague questions, they do need to
hit the books Or dig up old hobby electronic magazines at the used
book stores (though I think any such magazines have pretty much disappeared
from such stores by this point). But sometimes people just want
practical bits of knowledge, and they don't care how a diode works,
just what it does and how to use it.

i will try to answer a diode is a semiconductor that will pass current one way only basicly will pass electrons from node to cathode conventual current. an PNP is defined a positive and positive substrate and the reverse is for a NPN. this is simply put i suggest that you read about it untill you understand how a transistor amplify voltage and how they do work,
