Reply to "Semaphore and 555 Timer Circuit"

I found the comment curious when I saw the component.

FWIW, when you're drawing something like this and you know the right component is, say a 10k pot, and you're using a 500k because you have one in the junkbox, I'd still make the schematic indicate the correct value.  Most folks that are going to try to duplicate it should know that you can use a larger one and simply not use the full range.
