signal to analogue VU circuit ?

Hi, (total electronics n00b)

what is the circuit for signal to analogue VU ? eg: a line level (send etc.) to VU activity.

i've retrieved some VUs ( 2 mono, one stereo ), and i'm wondering if i can recycle them in some way, as a passive standalone device/s. i used to like the VUs on my first mixer. this is just a curiosity thing at this point.

if you're got any ideas for other creative audio use, interested in that as well.
thanks.

i'm looking for links, but all so far seem to refer to driving LEDs.
(what do you even call this type of VU meter?)

Required reading on the SVI ('standard volume indicator')

According to the Ampex list brain trust, the original and only 100% true 'VU' meter was made by Weston.
Sifam make a good knock-off. Most are not true 'VU' meters.
The mass of the pointer and the compliance of the restoring metal spring establish the precise ballistics.

For close-enough-for-Jazz, passive VU metering, you can use a DAT machine or spare D/A converter to signal to a meter's terminals, with a network of resistors in series and parallel so as to calibrate and dampen the response.

If so inclined, from this link, download two files:

VU.xls (a spreadsheet); and Passive VU damping.txt (the instructions).

Both files were provided by Dr. Christopher Hicks of CEDAR.

ok, so say this is not about accurate monitoring. i just have these parts, and wonder if i can make anything with them :-)
what about this 'ballistics' question? can that 'bounce' be used for anything? hehe
