Would it be helpful to have some kind of Sticky or other warning about the danger of operating LEDs without current restriction?
I have seen a number of instances of beginners' travails with LEDs recently, but this example involving a mains transformer and rechargeable batteries prompted me to put this in writing. http://forum.allaboutcircuits.com/attachment.php?attachmentid=35476&d=1319094779 We must hope that the OP for this article will get the necessary advice, but a standard reference would be useful.
From time to time I have considered referring such enquirers to Bill Marsden's comprehensive notes,http://forum.allaboutcircuits.com/showthread.php?t=19075 but as a relative newcomer here myself was unsure if that would be the done thing. There is also an article in the forum book http://www.allaboutcircuits.com/vol_3/chpt_3/12.html#03294.png This is all very useful, but I wonder if it may also help to have a short simplified warning presentation, in language aimed at the sort of real beginner who is in most danger of making these mistakes. It may be better for them to grasp the basics first, before moving on to detailed information and an interesting selection of LED circuits.
