    Help me explain how charging a capacitor works here?

    Can someone please explain this to me? https://www.youtube.com/watch?v=e3NDH-JDxXM In this video it seems as though he charges a capacitor to 400 volts with a 1.5 volt AA battery which makes no sense at all. I realize that I'm probably missing something major, but can someone explain how that...

    Switches and Power Supply

    Yeah Thats how I have it set up. But even when I have no wires for input at all the LED still turns on. As you can see here: **broken link removed** I have no inputs but the LED still turned on.

    Switches and Power Supply

    The top is CD74HC86E and the bottom is M74LS08P, but the bottom one works fine.

    Switches and Power Supply

    Alright thanks! One last thing, The top IC in the picture is an XOR. Why is it that basically the output is on all the time to matter the inputs? Two ground, two Vcc in, or opposites(which is the only time its supposed to light up).

    Switches and Power Supply

    Okay so i do need more power... and the switches? Also what does using a resistor do? And mister_rf what changes so I need to make? EDIT Nevermind, I saw the attachment but again what do resistors do?

    Switches and Power Supply

    Okay so I want to make a ripple carry adder. I have and XOR and AND IC's and they are wired up but I want to use switches for toggling the inputs. I bought two to test it out but they are a lot bigger than I thought so I don't think I can use them. Also I have a power supply that uses two AA...

    Making a Half Adder or possible other types of adders

    Would I just hook the battery up to the switches if I chose to use switches?

    Making a Half Adder or possible other types of adders

    Okay, thanks! Also two more things. What do I do about getting the input? Are there switches that I can buy? Also what about power?

    Making a Half Adder or possible other types of adders

    What is a good website to buy the gates from? Is this pretty much a schematic?

    Making a Half Adder or possible other types of adders

    Need help with making a Half Adder or possible other types of adders Hi, I was think about making a half or full adder (I'd make the half on first and if its not too hard I'll try the full), but I don't really know where to begin. I think I need a bread board but I don't know what type to buy...
