I got some of those cheap non-standard "VU meters" on Ebay and I found a driver circuit online. Here it is:
http://objectivesounds.co.uk/articles/driving-vu-and-other-ac-meters/
So, I want to try to run the "improved version" on a single 12v heater supply. How would you go about it? That's what I did, but for some reason, it won't simulate on SPICE. Returns floating point calculation errors. Please, have a look at the schematics attached, and let me know what you think.
