VU Meter

metal · 10th July 2005, 11:27 AM

Hello every body

I have deisgned a PCB for LM3914/5/6 for which it can be used as an audio VU Meter.

I just wanted to see if there are any comments, please don't hesitate to download the eagle files and comment or modify

Thanks in advance

perhaps you could put up a picture of the board, rather than the files, so that people dont have to download and open the files just to see it, not everyone has eagle installed

I would strongly recommend using the 3915 (the one with logarithmic scale - 3 dB per step) and using the full-wave peak detect circuit from the datasheet. It will produce a much more pleasing visual effect than just the chip alone.
