rtr12 posted:...I'm making the go-no-go one as well, but may do some more fiddling with some of the other suggestions above. The parts I ordered were just about the same as what Stan posted so I think I got that part ok. We will see when the boards get here.
So as part of the learning moment are you considering modifying the schematic and the actual PCB layout?
If so, I will describe my 2nd LED idea which would "cost" you 4 resistors, 1 capacitor, and the additional LED...but using existing values so no "new" values to procure.
