Long time since I've posted on Usenet.
What I want to do is give some public address system
operators (in a hotel actually), a clear and easy
visualisation of just how loud they have got things
running. A VU meter situation.

What they should be able to do is see, from a distance,
a meter which preferably will have a 270 degree travel arm

Small meters just won't cut the mustard. Ideally, too,
I envisage driving the meter from the amp speaker supply
so that's why I'm not employing electronic level display systems.
Trying to keep things as simple as possible.

It occurs to me that what I really should use is something
like a car's tachometer movement. I know modern units have
internal electronics etc. They would be un-necessary and
unusable so I'd be stripping them out.

In general, what are the movements?
Still D'asonval ?
What sort of FS sensitivity - 1 mA FS?
Anyone played with these things?
Thanks.

Hmmm. Off the top, an ordinary (wide pointer?) meter with a video cam
hooked up to a 17 inch monitor. I doubt that the hotel staff would
recognize proper VU ballistics.

?-)

1024 LED VU meter:

Kinda like a light show.

Kinda attractive but it would make my Cherry-brandy,
at the bar, a little black looking wouldn't it?
I wonder where GreenXenon got to -)

Black is the current high fashion color. The Darth Vader and Gothic
looks are back. Notice how HP printers went from all off-white, to
all black. Black is cool.

I think (not sure) that he's morphed into "Skybuck Flying". Same dumb
questions, bad physics, bizarre logic, and chronic computer problems.
I doubt that there could be two different humans with exactly the same
bad habits, strange personalities, and bad luck.
