I have always viewed them as on-topic here. I can recall a number of questions on power transmission lines and the like, and I don't remember any objections and certainly didn't object myself. I think the reason these questions are largely on topic is because the same theory ultimately is used to explain and analyze both signal and power applications. ...

I'm inclined to say that PLC software and programming is on-topic. (If you disagree, please feel free to downvote). Please note, I have very limited experience with PLCs, I welcome concerns and comments from more experienced users. The standard reasoning that we use for software and programming is that it's on-topic as long as it's not so removed from the ...

Asking about some detail of software that is for electrical engineering or related to equipment primarily for electrical engineering is on topic. We often get questions about Eagle, LTSpice, MPLAB, etc, and they are considered on topic. A logic analyzer is definitely EE equipment, so asking about software to use one is really asking for help with the ...

There is also the additional fact (as pointed out during earlier discussions about renaming the site) that "Electrical Engineering" has different meanings in different countries. In certain countries if you were looking for Distribution questions you would automatically search for EE and if you were looking for low voltage, digital analog you'd use a ...

I think most such questions will relate back to design well enough. In the case you pointed out, "how does this work?" is really "how does this design function?" or "why was this designed that way?". Note that "high-power" is a current (though not used very often) tag here. I think in my short time here, I've seen a power systems question or two received ...

I would say that questions about cell phone CPUs are subject to the same rules as every other type of CPU - shopping questions are off-topic, but design questions are fine.

What are the components I need for assembling a hobby mobile phone? Way too broad. Do you mean individual parts, like specific ICs, etc? Or do you mean high level, block diagrams? A hobby device is exactly like a commercial device. How would I go about assembling such a hobby device? Again too broad. There is no one way except "Soldering" Are there ...

What W5VO said, but in addition, make sure you specify your environment properly. State what hardware you are using, what language, what compiler or software environment if it matters, etc. We get too many questions here like "How do I set a single register bit without affecting the other bits" without specifying the micro or the language. Those will get ...

Yes, but questions about the application of commercial products are specifically off-topic. The reason for this is that without knowing anything about the design of the circuitry associated with the solar panel, it is impossible to infer anything about its behavior outside the applications specified by the manufacturer. You would either have to get more ...

In the "Don't ask about section" I would put a bullet point along the lines of: Homework questions unless you post an good faith attempt at a solution, with a specific question of your problem. Source: How do I ask and answer homework questions? Questions on the repair of consumer electronics, appliances, or other devices unless you can demonstrate a good ...

Those, simply, are not valuable questions. The answer can change at a moments notice, and due diligence on the part of the asker can make these better questions with a few hours work on their own. "There are thousands of parts available, which is best for me?" -- which is what all three of your example questions boil down to -- really doesn't help you, ...

No, it's really not a EE.SE question, and there's a two main reasons for it: It's a high-level question about computer software (video drivers). It is not an electronics design question In general, one should be familiar with the standards and requirements of a site they recommend migration to - just because it's off-topic on one site doesn't make it on-...

The first example would be off-topic, because it's too broad and also the internet is riddled with advise about car electronics (not as easy as wall adapter power, even though instructables makes you think it is) and 12V (9V~36V+) to 5V generation. So some personal research should give you more than enough to start with and ask specific questions about if ...

I have no idea what you're trying to suggest with such an odd tag. The question may be on-topic, but it is way too broad to seriously consider. Look at the help center for an indication about what shouldn't be asked, and you will find that your example is not a good fit for here or Stack Exchange in general. Hardware related software questions are ...

I disagree with Nick on this one. Your first question was a very generic question relating LCD display resolution to power consumption — an important engineering question for anyone in the business of designing such systems, and very much on-topic for this site. Your second question related strictly to the use of a particular device, not its design, ...


4

I think it's on-topic if it's a challenging question for you, but can't you simply look up the instructions and how they affect the flags? I wrote and ported a lot of math routines back in the day and all that information was actually necessary to do that job properly. Never had any problems finding it in the manufacturer's documentation (and that was long ...

If you're going to post software questions keep in mind: As with any question, the problem and\or question should be well documented, and conform to site guidelines. You should consider the likelihood of getting your question answered. If no one uses the software or the software is kind of obscure, then its probably better to find a different site. If ...

I can eventually suggest chat for this, which has much less strict requirements. The problem is that chat leverages far less visibility than regular questions, so if you're lucky, you'll eventually have an answer from a single guy (my bet would have been for PlasmaHH, but unfortunately he doesn't seem to be around anymore - probably The Photon, then). But ...

This is a common question, but the harsh reality is that it's not "our" job to find the right place for your questions. This is true for questions about where on Stack Exchange to ask a question, but also true for external websites. Any such question would turn in to a list-question, and Stack Exchange isn't great for those. Stack Exchange started because ...

[Let me preface by saying that I don't have a general prejudice against specialized EE software questions and EE lab equipment questions. I've asked and answered a few of those myself.] The question boils down to: "How to work the zoom on the Saleae logic analyzer chart?" It's more of a software (usability?) question than an EE question. As such, it's a ...

This sounds OK if you ask about how to go about testing a battery for capacity. If it's just "What's the capacity of this battery pack?", it's off topic and can't be answered anyway.

12 people upvoted your comment, but only you have voted to close the question. Nobody has downvoted the question, and it has attracted reasonably high quality answers. Personally I think it's borderline as to being on-topic, so I'm letting the community decide. Comment votes don't count. To reject a migration, the question simply needs to be closed. That's ...

Closing that question was inappropriate. It may well be that there is nothing one can do from inside LT Spice to use the specific processor more efficiently, but that's what the question was about. Perhaps the difference is that I've never used LT Spice, so it wasn't obvious to me at all that the question wasn't about some little-know app configuration, or ...

We have decided in the past to allow homework questions with an attempt at a solution. For those that don't: Close the questions, in a nice way. Ask the OP to provide a solution for the question. Unfortunately sometimes the site (moderators and ques) can't respond fast enough to questions being answered. The moderation team can send serial offenders a ...

I could see your proposed Q & A having long-term value to future readers (and therefore to the site as a whole), due to your experience at Maxim. On the "downside" there would be an element of opinion in any answer (e.g. perhaps someone from say, ST or TI, would say something different from you). But on the "upside", it sounds like ...

I agree that this could be useful to the entire community. I feel that a good answer: Would not name names. No mention of specific manufacturers or distributors. Would be fact based and not just speculation or opinion. Would be applicable two or three years from now, not just today.

Asking for product recommendations is off topic (for all of SE). If you need to ask these types of questions, the chat feature will be the best way, but YMMV. https://stackoverflow.blog/2010/11/23/qa-is-hard-lets-go-shopping/

One thing worth note here is the many similarities between PLCs and PLDs/FPGAs. I don't think anyone would label the latter off-topic here, nor that anyone would label VHDL or Verilog off-topic for this site. Historically, the first use of PLCs was to replace chains of relay logic. The first use of PLDs was to replace chains of digital logic. Then as the ...

You just need to close it, and it will revert back to the site from which it came.

Questions about use are off-topic. Questions on the use of electronic devices are off-topic as this site is intended specifically for questions on electronics design. Questions about repair are off-topic. Questions on the repair of consumer electronics, appliances, or other devices must involve specific troubleshooting steps and demonstrate a good ...
