Ok so a couple months back I had a question about a circuit I couldn't get to work that was supposed to alert the user when the circuit it was attached to lost power. We couldn't figure it out but KrisBlue, a user on here was kind enough to draw up a different circuit for me to use.
It works great, and he kindly explained how it worked, but after revisiting said circuit, I got curious and starting removing certain components to see if it would still function. It does, and now I'm terribly confused as to why and was wondering if someone could it explain its operation to me.
Here it is.
