    Re: Demystifying LEDs.

    Yep.

    This wasn't meant to be an exhaustive article covering every available option. It was mainly meant to cover 'standard' types which most of us will use for our mods. Typically, running 10-20mA...

    Re: Demystifying LEDs.

    There's a good write-up on wikipedia, but it's a bit too technical for most users, as it goes on about which chemicals produce which light etc. I concentrated on their use, since that's what concerns...

    Great. More information is always good, so long as it's not conflicting. Since you agree 100% with what i wrote, I guess that won't be a problem. I'm interested to see your animations...

    Re: Demystifying LEDs.

    Yeah, but I don't wish to confuse things. This is aimed at computer modders, who will mostly be using the 12V supply. Whilst it has resistance, it's negligible so I didn't mention it.

    Demystifying LEDs.
