OK, this is a spin off of this thread...
2 led timed circuit
It is funny, what the OP needed was actually much simpler than what I came up with. However, I came up with a circuit that shows how a basic SCR works.
I'm thinking of using this for one of the articles. I'd like to understand when something don't go the way I think it should. The first circuit doesn't work on the alarm/red light, the second does. I'd like to understand why.
