Well if anyone can post a simple schematic then I'd be (and I'm assuming everyone else would be as well) interested!
I have a simple setup that I think should work, using only 2 diodes, 2 caps, 2 resistors and 2 transistors which provides a basic delayed shutdown that should work. Super duper cheap and easy to implement. But it's not very versatile. Any more info on how to make the PIC setup work?
