I found VU meter schematic that uses LM3916 and UA741. It is velleman kit K4304. I'd like to use this schematic to buid my VU meter and so I have a question about it.
Is this schematic correct? Is there anybody who made VU meter exactly in a way that this schematic shows?
I ask about it, because velleman in pdf file wrote: “Modifications and typographical errors reserved”. So i can’t be sure that everything in this schematic is correct. That's why i ask You about it.
Well considering the age of the technology used (30 years or so), I would expect any errors to have been corrected by now!. The quote is just a legal thing, rather like everything you eat tends to say "may contain nuts".
I see, but sometimes they apply several errors intentionally in pdf files just to discourage pepole from doing projects on their own. They want people to by their kits. But maybe in this case it isn't true i don't know.
I thought that this schematic is well known and many people know if it works but now i see that i have to make it myself and try, then i will tell you if it works.
