    Underdriven 12V LED chips in a 120VAC system

    It depends on what you mean by "properly 12V rated", "work properly", and "shortening the life". I would tend to say no, but, based on your experience reading the LED resource, what do you think?

    Fuse identification?

    From what I can see it is 400VDC rated and can interrupt 100A. If you're really concerned, replace it with an HRC fuse. :-)

    How to fix uncontrollable volume of a portable AM/FM/SW radio?

    Excellent, well done!

    Great, even though I don't necessarily entirely believe you, this thread can now be closed.

    PSU advice

    I don't see a fuse. Even though you have fused plugs, I wouldn't feel comfortable without fusing my device. I see the two leads going to your mains connection, what are the other two connections to the primary side doing? They look a bit like they're just floating there disconnected. Have...

    Ultrasonic sensor not perfectly measuring distance|plan to use laser sensor

    Are the reasons you're getting consistent? If so, you could apply a correction to them in software.

    Underdriven 12V LED chips in a 120VAC system

    I have, and I think I might post about the obvious problems. My success rate in getting obviously bad items is about 75%. However, my success rate in getting refunds for the bad ones is currently running at 100% (eBay is good for something). As @Audioguru will remind me, I can't be sure that...

    Array in ascending order

    But what do the the parts mean? So far all I can see is that you've written some code and explained what it did. The fact that you can't understand the original code is evidence you don't understand the c statements it uses. If you understand the for statement For (a; b; c) { d; } Then...

    Underdriven 12V LED chips in a 120VAC system

    Read this. If you can get yourself to the point where you understand all of it, you're at a point where you can think about the project you're contemplating.

    Open collector problem

    Why not just as a pull-up resistor to your open collector output? The signal input to a string of neopixels doesn't require high power. I done see the reason for your circuit unless it's to provide some form of protection to the microcontroller.

    Array in ascending order

    Hi I'm that case you clearly don't understand. Research the c for statement and come back when you have learned what they do. Trying to claim you understand when you only have the vaguest notion is another example of your penchant for trying to run before you can walk. There are no short...

    Array in ascending order

    No, just the for statement. Do you understand it? What do the three parts of the for statement do?

    Array in ascending order

    So, what does this do? for (j = 0 ; j <(n-1); j++)

    Array in ascending order

    Do you understand "for" loops?

    Arduino system

    Firstly, the Arduino isn't a system, it's more like a module. And the differences between the various versions of the Arduino might not even matter for your application... Or they might be very important (you have given us insufficient information to tell). What does it take to "fire" this...

    Slayer Exciter with arcs?

    Yeah, but a straight piece of wire isn't a coil (but it does have inductance)

    New Here, Considering Capacitors.

    A screwdriver presents a very low resistance (very close to zero ohms) to the capacitor. This it often referred to as a dead short. The only thing limiting the magnitude of the current when you place a dead short across a capacitor is the resistance. In this case it may be the internal...

    What is this?

    Here are 1518 different littelfise diodes. Note that they are TVS diodes, a circuit protection device that is certainly related to their core business. They don't just do fuses.
