Will this work? All caps r 1uF (thinking of 2.2uF). Connections without a circle across it means there's no connection. Adapted from a commercial VU meter i saw somewhere. (Though not sure if i'm connecting it the correct way.) This is a left and right channel VU meter. Pin1 of the LM3915 is labelled in the diagram. Light blue dots are LEDs, Dark blue r caps, Red with black band r diodes (thinking of 1N914 and 1N4148). Cheers!
The pic isn't showing. It looks like they don't allow you to post images to other sites. Can you post a link? Not that I can actually help you though, but others might if they can see the pic.
Wicked circuit diagram! lol I think we need a few more labels on there saying what's what. What's that in the top left?
that's the audio jack thingy... Code: * >>> GROUND * >>> LEFT CHANNEL * >>> RIGHT CHANNEL the rectangular line ard it is to group it up.
ok, a couple of observations. The diodes in the inputs are not needed at all if you're using LM3914/3915 chips. Just hook pin 5 straight to your audio source. All that other stuff is unnecessary. You don't label your supply voltage at all, so it's pretty damn tough to read. The diagram you need to build is on page two of the LM3915 datasheet. One of those for each channel will do nicely.
Here I have a improved curcuit. (I renamed my file into a *.txt to fool the tripod server) Will this work? TIA and Cheers!
the host name portion of the URL has an underscore, that's illegal. (The http cops will be along shortly to issue your citation.)
will ya pls comment on tat curcuit??? (btw, learnt that only recently, rename image files to *.txt to allow off-site linking)
