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.
