creating a zenner like floating point using BJT


 

Hello , In the manual shown in the link the author says that the point I sighed in red arrow is floating at 2:46 and 32:20 time of the video.
How is this floating happening?
every potential needs reference, Why the pair of BJT shown in the red arrows is creating floating point?

Thanks.


 

There were no GRAPHICS in his post. It was a URL to a Video.

‘Floating’ is a poor choice of words on his part. That node will have a voltage Vbe(T6) above the minus node. ?


 

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.

No graphic showed up here, either.

To prove I'm not totally nuts (yea good luck with that Terry) I'm going do a screen print and post it in files under "IsTerryNuts.PNG."
Please view IsTerryNuts.PNG in the files section.
Now can someone explain how I can see the graphic when no one else can?

OK for the technobabble....
My primary net PC is a HP Probook 4530 8G of RAM laptop running Windows 64 bit professional with no tweaking, my secondary net computer is a HP netbook I keep for "on the road" [doctor's offices and the like.] The PCs are stock with no tweaking.

?
All 4 of these machines see what I show in the screen print.
?
I am really confused here.?
How can a Youtube video display as a PNG still graphic?
How/why are our PCs showing what no one else sees?
And, have I made a complete fool of myself yet? If not, lots of time left.

There was both.? John23's message had a URL to a video, and he also attached a screenshot with red squibblies scrawled on it.? By visiting the message on the groups.io website (99943), you can see it, below the URL.? It is a big graphic, with lots of circles and arrows and a paragraph on the -- oops, not that, but lots of scribbled stuff.
?
In my email program, the screenshot did not display; just a small icon saying something went wrong.? I don't know why.? Something about Gmail, perhaps.
?
Since this group allows attachments like that, and the group's guidelines say nothing about where to not put screenshots, I don't think john23 did anything wrong in that respect.? You can't criticize him for that.
?
I wish there was a Groups IO "how this system works" along with detailed rules.
It works pretty much straight-forward.? In most cases, it just works, the way it's supposed to work.? Yet you need to understand that there are things beyond groups.io's ability to control.??But if you want to know more about groups.io, read away.? They have plenty of instructions, with a link to them in the lower left corner of your screen.
?
As for "rules", that is what group Owners are for.? Owners set the rules for their group.

Graphics belong in the files section, please edit your post; delete and move the graphic to the files section.
If you don't I, or another moderator will be forced to delete this post.
Sorry, such are the rules of the road.
Really?? Here does it say that?? Where are the "rules of the road"?

Graphics in the messages section use a disproportionate amount of memory.
Graphics use about as much memory no matter where they are.? Admittedly, it is true that emailed graphics files use a bit more memory because the bytes need to be converted to make them text instead of binary, but that is a moderately small overhead.
