simply experiment with values. values are not critical. R = (when VU meter have big ohmic resistance put there 1K or something similar ) . C = (determines how fast will the needle oscillate / values in microFarads uF) D = just make from the AC the DC
Yes . C is there to smooth the " wave " [ how fast will the "needle" oscillate ] . R depends on your Voltmeter ... Try to experiment with RC values ...
@@AlbiDartanan thanks for the quick reply. I will definitely try it. A cheap voltmeter is around $3-4, while a VU meter can be around $25-40. Both are basically galvanometers. I can get a photo printout of an expensive VU meter background and paste it to a voltmeter.

I need a value of item not meaning of the symbol.
What are the values for C1 D1 C2 D2 ?
1st circuit it's almost an 1/2 wave rectifier, right?
Can I use this circuit to convert an ordinary voltmeter into a VU meter.
