    Default simple on/off timer - need help!

    Hi, I want to make a 5V relay turn on/off every 3 seconds.

    Anyone got some ideas of how to do this? Preferably with an analog circuit.

    it may seem simple, but I can't think of any good solutions right now..

    - Eric, electronics engineer student.

    You should already know how to do this.

    I do not answer private messages asking for help because no one else can: benefit from advice I may give or correct me if I'm wrong.

    Please ask on the open forum if you have a question and I'll be happy to help,     if I know the answer.
