LED oscilloscopes can be cheap and fascinating tools to look at some curvy signals, but the resolution is so poor! When Dave decided to build an XY LED oscilloscope, he wanted to go bigger as well and solder up 400 10mm LEDs. With an XY oscilloscope, you can take a look at Lissajous figures and even watch oscilloscope music on it!

Interesting project.

That was really cool. I never knew such a thing existed. It's kind of hypnotic. Put something like that on your desk and just watch the people get pulled in.
I wonder if I can voltage divide this to…
Thanks! You would need another frequency to show mains, otherwise if the frequencies are the same then you will only get a diagonal line. There are some pretty cool oscilloscope music videos on youtube…
