Help with starting out in electrical design

  1. Jul 1, 2010 #1
    Hi guys, ugrad electrical engineer here. I've never designed before and I'm thinking of starting out with something simple, like say, a timer that flashes a LED at a certain frequency. I know there are ICs out there that can do this, but can you guys point me in the right direction if I want to build it from simple components? (Instructions, websites, books, etc would all be much appreciated)

    Thanks again.

    Welcome to PF BrackenFernso.

    A good place for you to start might be with some http://www.ramseyelectronics.com/" [Broken].

    You mention flashing LEDs, so http://www.ramseyelectronics.com/cgi-bin/commerce.exe?preadd=action&key=MK176" [Broken] might be a good start.

    You could look into the 555 timer ic chip. It is very common and has many applications. You could replace the led with a speaker.
