  • Hi Nate:
    Great tutorial, thanks for doing this. I built the board as shown, but when I fire it up the first time, and connect the control wire to 5V, I hear the relay click on once, and then click off once, and then it's dead as far as I can tell.
    Any idea what a likely fail point is? The LED still lights up when I connect the control wire, but the relay doesn't do anything anymore.
    I'm fairly new to soldering, so could it be something as simple as not using a heat sink when I put the transistor on?
    Thanks very much for your help.

  • Are these coming back in stock soon? Hope so -- I have a project waiting on them.

No public wish lists :(
