I will place the order with Digikey later today unless you folks want to add some else to the circuit.
It is a great place! This is where I learn as well, as you can see, thanks to stan2004, gunrunnerjohn and many others too.
For your parts order, I just realized I didn't have any LED's listed. I'm not sure I have ever gotten any from Digi-Key, but I am sure they should have them. I got some assortments of red, green, yellow and clear at Radio Shack quite a while back. I have gotten some at Jameco and also on ebay. They are just the plain old 5mm ones. I also have some assortments of 3mm that I think came from RS as well, but I can't remember for sure. Anyway don't forget the LED's.
It's good to have extras of all this stuff too, mine sometimes go bad. I have no idea how this happens, but usually some circuit study and moving a jumper or two will make the next ones last a lot longer. It's still good to have extras.
I got the Knight Rider circuit off the internet too (like the traffic signals), but it seems like it also needed a little fiddling to get working? Neither the traffic signals or the Knight rider circuits were my design (I'm not that smart). They were both found on the internet and I just fiddle with them a little to get them working and made a new diagram.
