100 LED's Oscilloscope circuit | ONLINE ELECTRONIC ...

I really didn't have anything else better to do when I spent a day bending LED legs over to make this very limited o-scope. I built a tiny function generator board to play with the o-scope more, and I tried this board out with a commercial function generator-- it worked ok. You are not going to see anything like what you'll find on a commercial oscilloscope, but you will be able to pick out a square wave or sine wave. If you've ever thought about building such a circuit and wasn't sure how to go about it, I hope seeing this will help. My board is a bit oversized for the project, as you can see. If I had upped the LED count to 500 or so, I might have decent resolution, but I'd need a bigger board too! What I really use this for is watching audio output, kind of a funky looking bar graph type display. I've changed some values and added a resistor and a couple caps that weren't in the original schematic, but my board follows the book fairly closely.
