# MCU pushers, the lot of ya! [closed]

I see so many questions, including some of mine, in which a particular implementation is described and help is requested.

And, without fail, the team of MCU pushers comes around and strikes down any solution which does not use the MCU.

This occurs without even considering the original design requests.

A good example is I asked for a way to wirelessly send data. The question was even downvoted and all the information I got was to 'USE A MCU'.

Well, with only two chips I was able to solve my problem. Of course, I did not use an MCU. I stated in the question my reasons for avoiding on in this case. But, inevitably, I am given the normal responses: "USE A MCU! WASTE OF TIME OTHERWISE".

Just today there is a question regarding making a clicky sound with a relay. Of course, the gang comes around again. "USE AN MCU". Why? For god's sake, the OP is requesting a retro sound via analog means (relay or turn-signal clicker). It's not like he asks "How can I make the clicky sound". No, he asks "I want to make the clicky sound with a relay, how can I make it louder".

Why is there this great push for all solutions to all problems to be solved with an MCU? They are arguably less robust than most direct solutions, and they abstract the problem space to an area which may not benefit the person asking the question.

I understand that MCU's are powerful tools that can do great amazing things.

For example:

• light up a matrix LED display to music;
• control a remote car or drone;
• control a smart fridge;
• control a camera;
• track my energy usage and wirelessly relay this to the energy company;
• run my thermostat with my time and temperature preferences;
• send sensor data in real time to central hub;
• control the timing of my garden watering schedule taking into account rain and sunshine;
• analyze plant controls and implement feedback;
• and a million other practical examples

But I am getting a little tired of every question in which a particular implementation is provided being rebuffed with "USE AN MCU" (without even analyzing the originally presented idea by the OP).

Can we please judge each question on its own and not automatically assume the user is an ill-informed idiot who should use an MCU?

• I'm voting to close this question as off-topic because it isn't a question at all. – Dave Tweed Oct 8 '16 at 20:57
• @Dave Tweed: As I expected. I tagged as "discussion" so that it could be discussed. The site has a problem, which is the incessant pushing of MCU's for simple design problems. You can discuss it or you can "make me respect your authority" and close the question. Really pathetic honestly. I put this on meta because it is a meta-problem on the EE stack exchange. – jbord39 Oct 8 '16 at 21:06
• @Dave Tweed: Put on hold because "does not appear to be about Electrical Engineering Stack Exchange " Yet the question is 100% related to Electrical Engineering Stack exchange; how can you even deny it? This is another problem. High rep users just arbitrarily closing questions based on them not liking it; taking on some random arbitrary reason to close it. So pathetic dude, I guess you retired and now no one listens to you so you build up high rep here and close questions? – jbord39 Oct 8 '16 at 21:08
• @Dave Tweed: I insulted your answer and you lash out by closing question. If you were truly objective you would base your decision soley on the question and not on myself personally. Another high-rep user abusing his privileges. Can we make downvotes -10 rep so people can't just grind out rep like the wild boars in world of warcraft??? – jbord39 Oct 8 '16 at 21:09
• @DaveTweed: From the help center: "Electrical Engineering Stack Exchange users to communicate with each other about Electrical Engineering Stack Exchange (asking questions about how the websites work, or about policies and community decisions)" This is a question which you may not like. But how can you say that it is not a "communicating with each other about Electrical Engineering Stack Exchange community decisions". You are a fascist if you say otherwise. – jbord39 Oct 8 '16 at 21:12
• Wow, you are really angry about something, but I'm beginning to think that the stated topic of your question really has nothing to do with it, other than being the proximate trigger for your tirade. Would you like to take this to chat? I've got a couple of other things going on right now, but I'll try to be as responsive as I can. – Dave Tweed Oct 8 '16 at 21:25
• I would love to. And no, it is the stated topic which is bothering me. I was hoping responses would be more like "well you see many times in the past people came and we gave them direct solutions and they never worked so now we always push mcu solutions" but instead I get ridiculed for honestly a completely legitimate inquiry about a real problem on the site. MCU's are not the end all be all. You can do stuff with transistors and resistors, even in the 21'st century. And my questions get getting downvoted because I say this. – jbord39 Oct 8 '16 at 21:28
• Good questions yield good answers. – Scott Seidman Oct 8 '16 at 21:29
• And in the case of my wireless transmission an MCU is stupid. It really is. I still have to send the data through some encoding and antennae. Since the data is 1-bit, changes once every couple seconds at most, is very noncritical, what is the point of the MCU? On top of that the analog aspect of it almost increases the security compared to a vanilla MCU implementation!! There is no analysis. It is like using a chainsaw to cut a flower. It was a blanket response which given the design still has no basis. Defend it if you want, but a direct solution was better. – jbord39 Oct 8 '16 at 21:30
• Did you notice that NOBODY gave you an MCU based answer to the wireless thing, and nobody down voted the question? It's hard to understand what you're whining about. – Scott Seidman Oct 8 '16 at 21:57
