    Capacitor discharge pulse circuit topology, series capacitor?

    I would say there is little difference between them. The main distinction is that one charges the capacitor through the transformer and the other doesn't. If you're going to have a current limited charging circuit that charges at a rate which is lower than the holding current of the SCR, then...

    Print the string of structure

    Then do what I say and write a program which prints the value of the indeed loop after the loop. I have asked you to do this three times and I won't ask you to do it again. int i, j; j = 10; for (i=0; i < j; i++) { printf(" number %d \n", i); j = 3; }...

    Are you sure? Feel free to ignore me. You tend to do that.

    Then you don't understand how the for statement works. Perhaps you can write the program and try it out. And when you discover that something unusual happens you need to be able to explain it. But before you do, read the last two paragraphs of your post 33 and see if you can see where you...

    Underdriven 12V LED chips in a 120VAC system

    Again, if you had read the resource I pointed you to, you would realise that a small increase in voltage can cause a large change in current, AND that you can't predict the actual current for a specific voltage. As @Audioguru has pointed out, LEDs should be driven from a current source, not a...

    Motion sensor timing

    Katie, it's just frustration. The problem we have is that people with no knowledge come to us with the solution they have thought of, wanting help with it. Unfortunately, if we don't know the actual problem they're trying to solve, the answer we give may end up being totally unhelpful. What...

    In that question a, b, c, and d represent initialize, condition, increment/decrements, and statement, respectively. You've shown the same thing in your while loop. All I was asking you to do is match up which of z, y, x, and w were initialize, condition, increment/decrements, and statement...

    Open collector problem

    OK, now I get what you want to do. There are a number of options depending on what you're trying to optimise for. Some options are board space, cost, "simplicity", and speed. The best solution may also be affected by what parts you happen to have on hand. Here are a few options: Get an...

    Underdriven 12V LED chips in a 120VAC system

    And you only just noticed this? But yeah, We should have warned the OP that he could kill himself, and that the insulation resistance of these COB LEDs are unknown.

    @vead, can you answer the question possessed in post 28? The c for statement is especially completely and subtle compared to other languages. I feel you're using it in a very cookie cutter style without understanding it. What would you make of: for (int i = 0; i++ < 10;) printf('%d', i)...

    Entering square bracket in text

    Yeah, they're not implemented here, but there is a way in the software to do it. The "censoring" allows the operator of the software to provide a list of words and what they will be rendered as. You might have "shit" become "****", to limit the effect of poor use of language. It's actually...

    Underdriven 12V LED chips in a 120VAC system

    At low currents you can see that the module you have has a number of bright points on the surface, each of these is an individual LED. It's not uncommon for each of these to be rated near 1W each, but it can vary substantially. The specs you linked to indicate that the base of the module is...

    Print the string of structure

    If you understand the for statement For (a; b; c) { d; } Then you can trivially give the mapping of a,b,c, and d to w, x, y, and z below z; While (y) { x; w; } The answer is something like a = w, b = x, c = y, d = z <-- but it's not that.

    Entering square bracket in text

    You're giving away all my secrets :-) Another way is if you set up the censoring to change \[ into [ and \] into ].

    Print the string of structure

    Vead, Imagine you asked me to prove I could drive a car. Imagine I replied with two photos showing the car in different places. Have I demonstrated I can drive a car? Your attempts to show your understanding of C is very similar. I suspect that you don't understand much at all, and your...

    Underdriven 12V LED chips in a 120VAC system

    If the unknown LED is nominally rated at 12V, what voltage is safe to restrict the current to a safe value if you use an unknown heatsink at an unknown ambient temperature? I don't know the answer, do you?

    Print the string of structure

    Do you understand the c for statement? Do you understand how a string is stored? Do you know how you determine the length of a string? Do you understand loops at all? You've either said yes to these questions (or ignored them) previously. Your question indicates the answer is probably "no"...
