Mainly, though, this is a larger-than-a-bell-jar kind of operation.

Thank you. There's yet another LTSpice Tutorial at

LTSpice needs to be overhauled by someone to bring its adherence to UI
conventions forward to 1993.

It's like something written by someone who has been living on an island since
1985, who hasn't received any software update since Windows 3.x running on DOS.

What kind of power does that thing draw?

I don't know the exact numbers, but it is in the multi-KW range. But
it's "efficient" with switchers regulated to supply just the exact
amount of forward drop required by each LED grouping.

...Jim Thompson

Do you also have a constant current in the design, or do you just supply
"exactly the right voltage"?

I was actually thinking about this, is there such a thing as a switching
constant-current source, rather than a switching voltage source?

Whether you regulate current or voltage depends on what information you convey
in the feedback signal. If the negative feedback signal is derived from a
voltage across a current-sensing resistor, then you have current regulation.
(That is the high level view; the devil is in the specific details, always).

Also, regulating current seems to be, in a sense, "native" to the switcher.
Justification: what does an inductor "do"? It "wants" to keep the same current
going!

Yeah, that makes sense...

Lordy are you ever off the wall. Ctrl-Z predates MSDOS for talking about

And I found a peculiarity... you can only drag components, not wires.

...Jim Thompson

My annoyance is when you want to extend a schematic. The workspace does not
quite behave as an "infinite sheet"; it shows a kind of "resistance" against
growing larger to make room. In other CAD programs, you can more easily
navigate in any direction away from the drawing and start drawing there.

Here is a test. Make a new drawing. Hit F2 and place a component. Now hit Space
to enlarge the view so that it contains pretty much nothing but that component
with just a bit of space around it.

Now hit F2 again and try to place another component somewhere reasonably far
away from the existing one. If you move toward the edge, the program doesn't
scroll. Or it only scrolls a tiny bit and then stops.

If you're near the edge of the view and use mouse wheel to zoom out, it zooms
out in such a way that not much new area of the "world" is revealed at that
edge; but rather at the opposite edge. So if you want to extend the drawing at
the bottom, you have to go to the top, zoom out, and then you have extra
space at the bottom.

Is there a way to just scroll through the drawing?

My fingers seem to want to just hit Shift in an empty area and drag the view
around with the mouse while maintaining the same zoom level; that would be
good.

Another alternative that would work would be to be able to set the size of the
drawing in some dialog somewhere, and have scrollbars whenever the view doesn't
show that entire size.

And: there is a checkbox for reversing the direction of the scroll wheel;
another pet peeve of mine. Scroll-up to zoom out is just a wrong-way default
that can be fixed in one click, Yay!

Every other program that has anything to do with drawing that I have
ever used does it like this: roll the wheel up == zoom in.

Wow, so much better now ...

That's fundamental... a rule of thumb that makes some circuit analysis
more intuitive, particularly finding starting points in switchers
_and_ oscillators:

(1) The current in an inductor can not instantaneously change.

Likewise:

(2) The voltage across a capacitor can not instantaneously change.
