Tutorial - Controllable Power Outlet
about 8 years ago
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 :(
