Have fun; I hope your ok with me putting the animated .gif on the other "Thread" I slowed it down. I've been wanting to slow it down; ever since I seen it.
Someone first posted it in the "Members Lounge" my mind *popped* when I seen it for the first time. I just felt it was running way to fast at the time.
I added it for anyone who might read your "Thread" just as a visual for those who need it. I've seen it on my Scope; but for those who don't have one.

Edit: Thanks to DP for taking a look and making sure its a good circuit.
