Re: LM324 based automatic voltage stabilizer circuit simulation
Quite apart from that, it's impossible to
simulate that complex circuit without the full specification of
every component. This is undoubtedly impracticable.

You are right, dropping Character Map would be a dumb idea. When I still used Windows years ago, it was a useful tool to me. I used it often to copy/insert non-standard chars into documents. Change for the sake of change is the dumbest idea ever, in my opinion.

I'm guessing that you uploaded it to a different group and later downloaded it from that other group.? Or maybe you imagined doing both?? But the modified file never made it to the group until now (0111 UTC).? It would have to be a really major "glitch" for the file to show up but have no record of it in the group's activity log, and then to spontaneously disappear some time later.

Re: Confused, adding a pin to an existing Symbol and .cir
But I see that the one I had was quite different from the one you uploaded in August.
Seems to work, and has the same calling structure (A B W Vpct vs. 1 2 3 Vpct), so def related.

A while back I uploaded "Multi_VCPot_Test_20240813.zip" that demonstrates how to use multiple vcpots.
And...yes..each pot has a hidden pin that expects a voltage source to control the rotation percentage.
If each pot is expected to rotate independently of each other, then each pot requires a dedicated rotation voltage source.
Or, they can be ganged together by using a common voltage source.

Re: Confused, adding a pin to an existing Symbol and .cir
OK, something possibly glitched at Groups.IO
I did a new download (twice) and found no pot.asy – as you said.
But an earlier download of the same file does have the .asy!

I jus now updated the upload, downloaded it, and *this* one does have the .asy

Re: Separate from .CKT for .lib file
Thank you very much for your help.
Chances are good that the photodiode part is smaller, so it might be easier to single it out. ?It might be as simple as one line in the model file, or it could be dozens of related lines.
SPICE netlists are not hard to figure out. ?For example, any line starting with "R" is a resistor. ?"D" is a diode. ?The first letter is always the key.

Do both; put them in the .ASC folder AND in

I understand that and it's easily feasible, by creting your own
directories. I used to do that but you run the risk of making
your project not portable if you forget to join all the
necessary files (models and symbols) needed to run it.
I have long ago decided to put them in the same directory as the
.asc, at the cost of having to copy numerous files.
Just my $0.02...
