Hum, on both of my net PCs and my wife's win10 and Mac, there is a graphic of the circuit in question. I guess Groups IO now automagically inserts graphcs from URLs. Odd since it comes from youtube and is a is is "2.png."
I wish there was a Groups IO "how this system works" along with detailed rules.
I'm going to delete my "edit and move the graphic or this post will be deleted."
Thank you for letting me know the graphic isn't embedded in a message.
