Well, everyone has different levels of understanding in this field. It seems that the lower-level the question, the more people it will help. So to an extent the rating for that answer is somewhat valid.
Hey, so I'm using an op-amp here, but the circuits hooked up to input and output pins don't share a common ground. (I have a microphone as the input). How should I wire this?
I'm trying to use it as a non-inverting amplifier.
only time I had to do it was to fix some old dumbass engineer's mistake that ended up having a composite video signal 2x the level it should have been
then I realized that the eng. director listened to him as though he knew everything, and that I would be stuck working for people like that forever, so I quit being an engineer
From a young age, most people are told that vegetables are really good for you and you must eat them...
But why? If I eat loads of vegetables for a week, and then the next week I eat nothing but burgers and fries I don't feel in the slightest bit different.
Different people have different taste...
Hey, seeing as how there are 2 more people in chat now, maybe someone knows the answer to my question: I'm using an op-amp here, as a non-inverting amplifier, but the circuits hooked up to input and output pins don't share a common ground. (I have a microphone as the input). How should I wire this? (I'm trying to use it as a non-inverting amplifier. But it's being fed into a microcontroller after this for processing, so inverting is ok if necessary.)
Well, the microphone is piezoelectric. So it produces its own voltage across 2 leads. The amplifier is being powered off of a battery. So they don't share a ground.
A question I asked on a mailing list. Thought I'd echo it here.
I just want to brainstorm something I'd like to exist, and I want a reality check from people who really know about radio / electronics etc.
I'm trying to find smaller, more flexible input devices for electronics projects : at firs...
Is it OK to ask questions that are really just requests to brainstorm with the community?
I'm referring to this question, which just came to the top of the main page. It caught my attention because it mentioned brainstorming explicitly, even in the title. However, this type of question has b...
pic kit 3 is the ish, its back with full features.
as low value because it has no meaningful content.
"is the ish" is slang (afaik) for "great" or "excellent". I know we're supposed to be nice to new users, but this is not a very good start. I think that cases this bad should be deleted, with a comment stating that the question already has 7 decent answers, and that more content is necessary for an answer to be worth keeping.
There's a point where an answer is so bad that it's unacceptable and should be deleted, and where a new user just needs some help getting answers up to standards. This one, I believe, falls on the delete side of that line.
Does anyone else know if Daniel/oengenheiro is ever in chat?
Yeah, it's a Javascript LaTeX engine that gives us beautiful mathematical equations. I'll post that sandbox/formatting question on the site shortly with links to documentation etc.
Hi! That's funny, I haven't seen you around much. Anyways, I was a little confused by how you handled that answer on the PICKit 3. I don't want to nit-pick, you've got the diamond by your name, but I was curious if you saw something in the user or answer that I didn't, or knew of a policy that I'm unaware of. Or, maybe you were feeling particularly generous.
Purpose of question
We now have $\LaTeX$ support through MathJax. Now, instead of writing equations like this:
w0 = 1 / sqrt(L * C)
we can write:
$\omega_0 = \frac{1}{\sqrt{LC}}$
Hooray! However, TeX has a steep learning curve, and it will take some time to figure out how to use this fe...
I didn't either, and I'm a 22-year-old American kid. Had to do some googling. I think it's derived from "is the s**t", which has the same meaning, though I don't understand that one either.
