    I'm trying to make an LED blink using an LRC circut,
    but I'm having a little trouble. Could someone give me some pointers. Any help is appreciated.

    I'm not surprised. Why do you think that a completely passive circuit will perform the blink function?

    It sounds as if the idea comes from somebody who is not too conversant with electricity. You will need an active device like a 555 free running oscillator to be able to blink a LED. Bouncing charge between a cap and a coil doesn't work very well.

    Oh, okay. Well I guess that's good. I've been working on it for about two days without success, and thought it was my fault. Thanks for the help.
