Reply to "Semaphore and 555 Timer Circuit"

Stan, this sounds very interesting, I might just give it a go. Pretty sure I have some CD4070s  XOR in a 14 DIP package, would that work? There's a chance I might have some of the 74xx86 also, but not sure of the AC part of the number as above? I'll look around. Why I am not sure, but I have been adding a logic chip or two here and there for a while now so I have a few on hand, but I am not sure of exactly what all I have so far? If I live long enough I might even learn what one or two of these are used for. 

GRJ, I did order a PICKIT 3 (I think it was?), the cheaper one. I don't know how to use it, but there are directions available and youtube (see above line about life span and learning all this).

After that I looked at the selection of PIC chips available and got completely lost as to which one to choose? I'll take the chip number you posted and maybe give those a go too. I'm definitely saving that PIC number. Lots of learning to be done on the PIC stuff too, as Sgt. Schultz would say, I know nothing!

I really do enjoy the LOGIC ICs though. It's both confusing, exciting and challenging all at the same time! (Not that the PICs wouldn't be as well.) Plus I learn more about using Diptrace at the same time and it's fun.
