    I have moved this article to here, for formatting reasons I've explained in the new thread. Please do not post here, it will be ignored (by me at least).

    If you want to offer constructive feedback instead of rambling incoherently with yourself, then feel free to do so; remember this article is very much a work in progress. Otherwise, just pass by the thread by and keep your comments to yourself - Dave

    Just relax... this article is great for people just starting out. I found it helpful. Also note that he said most leds - not all. 1.8v white LEDs are uncommon, just because you have them doesnt mean the article is wrong.

    Seems there are always exceptions; most LED's mark the cathode with a flat spot or a dimple on the case bottom or a short lead; but not always, I have both, so always check first.

    Bill, would 1N4002 be ok to use for CR1 to 8 in your cyclon and emergency circuits?

    Yeah, almost any diode will work. The 1N4002 is a 100Volt 1Amp unit, so it is overkill, but not a bad choice.

    At this point I'm asking a moderator to close this thread. Thanks.
