rtr12, are you building both the Knight-Rider and the traffic-signal projects? I'm getting myself confused on who is doing what and don't want to send you off on a wild-goose chase! That is, I know Kris has a MP3 sound module for his Knight-Rider and it's going on rolling stock so what I suggest for his application may not apply to yours.
If you're doing the traffic light I'm pretty sure you want to replace the 1uF capacitor supplied with the kit with a 10uF capacitor since the lights change every so many seconds rather than several times per second in the Knight Rider. This value difference is shown in your schematics but again if you are starting with the assembled waterfall board it may not be obvious since the capacitor is one of those surface mount parts too small to have its value printed on it.
Sorry, I didn't mean to confuse. My writing is not always the best either, I confuse myself sometimes when re-reading things I have previously written a day or two before. The old brain goes faster than the fingers and it also abbreviates and skips a lot. 
I am just getting the kits for experimenting and possible future use. I have some needs and ideas that are far from well defined like Kris's are. I am also interested in the mp3 stuff you all are working on, but I am just following along on that one, trying not to get in the way. Some of the things you and GRJ were talking about in his sound player thread were way above my pay grade.
As you stated earlier, the fact that the kits have the PCB really opens up a lot of possibilities for different things when I finally pin them down. I will probably try to make at least one of each in a few weeks when the kits arrive. I got plenty of kits just in case there is an oops somewhere during construction. 
I really like fiddling with all this stuff and learn something with each new post from you and GRJ and some of the other electronics folks here. I think some of it is actually starting to stick and even make sense too.
I really do appreciate all the help you guys offer here too.
