    admirlk got a reaction from enl in Circuit Help   
    Hmm, After going through 300 or so magazines, I found one project using a LM3914, but it was unhelpful. In my web searches, that landed in a forum where this question was asked, someone always says there is an example in the datasheet, but no matter how many times I look I cannot find it. Or that examples are readily available, but that is close to an example as I can find, which is why I tried asking for myself. A couple times a circuit similar to the one I mentioned was mentioned, but only as far as a parts list. I did finally find one, in the datasheet, that had a switch, so I have an idea of how to do that part now. I am still not clear on how to do the hold though.
    The chip really has not been obsolete for that long, I think it was still readily available at the beginning of last year. I have never had a problem buying from China, other than waiting a month to get my order. As long as they work, it is not taking away from anyone, since the original manufacturer stopped making them. At 10 for < $5.00 shipped, I will have plenty of extras, if I ever need them also.

    Well, we are in the same boat then, so maybe it is even ones out.
    I just started writing my current project, desktop app, for real. I used no documentation in the "breadboard" versions, so I am having to go back to the APIs and relearn what I did. Unfortunately it is all sub-classes, at this point, so I am not sure where I added functionality for one operation, or another. Since I do not remember what order I added stuff in, I do not Know if things that are not working just need other sub-classes fleshed out, or if I am doing something wrong. I just need to remember to go back and document my real code when I figure out what the problem was.

    I know this is an older post, but it struck a "pet peeve" nerve.
    I recently went back to school, I had to learn how to use a calculator because they were not allowed in math class when I was in high school, and was surprised at how often people did not bother to even copy things by hand. When we had peer reviews, or otherwise were able to see each other's code, there was always at least one that was a direct c&p of code that did not even work. Had they copied it by hand, and read it in the process, they would have realized that it did not work. Keep in mind, these are simple school problems that have numerous examples on the internet. I have also seen, many times, where the code seems to have been intentionally written wrong, but someone who actually reads it will be able to fix it easily.
    When I have problems with code, I am often reluctant to ask questions because I do not want someone to just write it for me. I appreciate answers that simply point me in the right direction. On the other hand, with electronics, I tend to look for a more definitive answer. This is usually something like what size cap should I use, because I am trying to copy something that did not give the value, and I am just trying to get it to work, without ordering "one of each" or frying something.
    Personally, I appreciate everyone who tries to help me.
